Egg whites stiffen when they are whipped. The change that occurs in the protein is called ___________.a. denaturation. b. translocation. c. transcription. d. deamination.

Answers

Answer 1

Answer:

Denaturation

Explanation:

Proteins are huge molecules that need to get an accurate tridimensional structure to accomplish their function.

In water, these molecules keep their hydrophilic parts in the outside and the hydrophobic part in the inside.  

There are some treatments like changes in temperature or pH that provoke changes in the tridimensional structure of the protein. This process is known as DENATURATION. The protein losses its original native structure and its properties.

When denaturation occurs the protein tends to join together with other denaturalized proteins through the areas that repeal water, becoming coagulated.

Answer 2

Answer:

Answer is A. Denaturation.

Explanation:

Denaturation occurs when there is a disruption in the highly ordered or molecular structures, i.e, the secondary and tertiary structures ,present in the native state of the protein.

Denaturation can be caused through the application of some external stress, heat, inorganic salts among others.

Answers

Final answer:

In binomial nomenclature, the genus represents a broader categorization of related species, and the species denotes the specific type of organism within that category, like in Homo Sapiens, where Homo is the genus, and Sapiens is the species.

Explanation:

In the binomial nomenclature, which is a scientific system of naming species, the genus functions as a broader categorization and the species functions as a specific designation within that category.

For example, in the name of the species Homo Sapiens, Homo refers to the genus, which encompasses all types of human species that exist or have existed, and Sapiens is the specific species that represents modern-day humans. The genus (Homo) indicates the related group of species, while the species (Sapiens) denotes a specific organism within that group.

How do photosynthesis and cellular respiration contribute to the carbon cycle?

Answers

Answer:

Carbon cycle may be defined as a type of biogeochemical cycle that regulates the amount of carbon in nature. The carbon is released by the living animals and utilized by the plants in form of carbon dioxide.

Photosynthesis consumes the carbon dioxide to make carbohydrates where as cellular respiration releases carbon dioxide and breakdown the carbohydrate. Both these process helps in recycling of the carbon in nature and maintains the level of carbon in nature.

Photosynthesis removes carbon dioxide from the atmosphere and produces glucose and oxygen using sunlight. Cellular respiration uses glucose and oxygen to produce ATP, releasing carbon dioxide and water in the process.

Photosynthesis and cellular respiration are fundamental processes in the carbon cycle, which maintains the balance of carbon in the environment.

Photosynthesis :

occurs in photosynthetic organisms like plants and some bacteria. During this process, carbon dioxide (CO₂) and water (H₂O) are converted into glucose (C₆H₁₂O₆) and oxygen (O₂) using the energy from sunlight. This reaction can be summarized by the equation:

6 CO₂ + 6 H₂O + light energy → C₆H₁₂O₆ + 6 O₂

Cellular Respiration :

takes place in the cells of all living organisms. Here, glucose and oxygen are used to produce energy in the form of ATP, releasing carbon dioxide and water as byproducts. The general equation for cellular respiration is:

C₆H₁₂O₆ + 6 O₂ → 6 CO₂ + 6 H₂O + energy (ATP)

These two processes are reciprocal: photosynthesis removes CO₂ from the atmosphere and produces O₂, while cellular respiration uses O₂ and releases CO₂. Together, they form a continuous cycle that is essential for life on Earth.

B) cannot take place because Japanese goods and services will be less expensive than French goods and services.
C) cannot take place until French workers become more productive.
D) will take place so long as each country has a comparative advantage in a good or service that buyers in the other country want.

Answers

Answer:

Option D, will take place so long as each country has a comparative advantage in a good or service that buyers in the other country want.

Explanation:

Trading or globalization is a concept where services or goods of one  nation can be exported to other nation in terms of some monetary benefits of technological advancement. Two nations will be into a trading partnership till the service or goods of the two nations provide a comparative advantage over and above trading with any other nation. Thus, France shall be taking benefits of better productivity of its workers for meeting out the demand of its citizens in lieu to provide open market for business opportunities in other sectors as well to japan.

Hence, option D is correct

Final answer:

Trade between Japan and France can take place as long as each country has a comparative advantage in a good or service that the other country wants.

Explanation:

In this scenario, the correct answer is D) trade between Japan and France will take place so long as each country has a comparative advantage in a good or service that buyers in the other country want.

Comparative advantage refers to the ability of a country to produce a good or service at a lower opportunity cost than another country. If Japanese workers are more productive than French workers, Japan would have a comparative advantage in producing certain goods or services. Similarly, if French workers are more productive than Japanese workers in other areas, France would have a comparative advantage in those goods or services.

Therefore, trade between Japan and France can occur if each country specializes in producing the goods or services in which they have a comparative advantage, and then they can trade with each other to obtain the goods or services that they do not produce efficiently.

Three different alleles (c1, c2, and c3) at the c locus exist in a hypothetical population of juniper trees. If the frequency of c1 is 0.3, the frequency of c2
a) cannot be less than 0.3.
b) cannot be greater than 0.3.
c) is 0.7.
d) cannot be greater than 0.7.

Answers

Answer:

d

Explanation:

When considering the frequency of the potential alleles of a gene in a population, the total must add up to 1. Think of it like percentages. an allele frequency of 0.3 means 30% of the population carry it (out of a possible 100%).

We know that the frequency of c1 is 0.3. Lets take each option and see if it can be true

a) cannot be less than 0.3.  - false. It could be less than 0.3. For example, it could be 0.1, meaning the frequency of allele c3 would be 0.6 (because 0.3 + 0.1 + 0.6 = 1)

b) cannot be greater than 0.3. - false. It could be greater than 0.3. For example, it could be 0.5, meaning the frequency of allele c3 would have to be 0.2 (because 0.3 + 0.5 + 0.2 = 1)

c) is 0.7.  - false. It can't be 0.7, because that would mean that the frequency of c3 is 0. (0.7 + 0.3 = 1)

d) cannot be greater than 0.7. - true. It cannot be greater than 0.7, because  that would mean that the frequency of c3 is 0. (0.7 + 0.3 = 1)

Final answer:

Given the allele frequencies in a population should add up to 1, if the frequency of allele c1 is 0.3, the frequencies of c2 could, theoretically, range from 0 to 0.7. Hence, the frequency of c2 cannot be greater than 0.7.

Explanation:

The question relates to frequencies of alleles in a population of juniper trees. There are three possible alleles, denoted c1, c2, and c3 and we are given that the frequency of c1 is 0.3. Considering the principle of population genetics, the total of allele frequencies in a population should add up to 1. In this case where there are three alleles (c1, c2, and c3), if the frequency of c1 is 0.3, then the combined frequencies of c2 and c3 would be 0.7 (1 - 0.3).

Therefore, the frequency of c2 could be any value from 0 to 0.7. The only suitable answer provided is option d) cannot be greater than 0.7.

Answers

Answer:

3. intestinal phase

Explanation:

Intestinal phase starts at the first segment of the small intestinal where we have the duodenum. In this phase, the partly digested food called chyme stimulates the enteroendocrine cells of the duodenum causing the release of the secretin hormone. The secretin is one of the hormones in the duodenum. It is a peptide hormone that functions mainly in regulating the acidity of the duodenum.  The secretin hormone stimulates the secretion of bile in the liver and also initiates the secretion of bicarbonate in the pancreas in response to the acidity of the chyme.

Which of the following is an effect of myelination?

A) Myelination increases the rate at which phagocytosis occurs in the brain.
B) Myelination increases the speed of conduction of action potentials.
C) Myelination increases the rate of mitosis in damaged neurons.
D) Myelination increases the volume of cerebrospinal fluid in circulation.

Answers

Answer:

B) Myelination increases the speed of conduction of action potentials.

Explanation:

Myelination can be defined as  the process of formation of  myelin sheath around a nerve to allow nerve impulses to move more quickly.

Myelin is a fatty substance  that is rich in lipid which surrounds nerve cell axons to insulate them and increase the rate at which information  that are encoded in form of electrical impulses are passed along the axon.

Generally, myelin increases the transmission of electrical impulses called action potentials along myelinated axons by insulating the axon and reducing axonal membrane capacitance.

Final answer:

Myelination is a process that forms a myelin sheath around nerve fibers to speed up the conduction of nerve impulses. Therefore, the correct effect of myelination is the increase in the speed of conduction of action potentials. Myelination does not predominantly affect phagocytosis, mitosis in neurons, or the volume of cerebrospinal fluid.

Explanation:

In the central nervous system, myelination is the process of forming a myelin sheath around a nerve fiber to speed the transmission of nerve impulses. Among the given options, the correct effect of myelination is: Myelination increases the speed of conduction of action potentials (Option B).

The myelin sheath works like an insulating material, allowing electrical signals to jump rather than slide down the nerve fiber. This increases the speed with which these signals travel along the fiber, which is critical for rapid communication between the brain and the rest of the body. Thus, myelination does not primarily influence the rates of phagocytosis or mitosis in the brain or the volume of cerebrospinal fluid in circulation.

Which principle of stratigraphy could be used to determine the relative ages of Layer 7 and Layer 3?
a. the principle of fossil succession.
b. the principle of original horizontality.
c. the principle of lateral continuity.
d. the principle of inclusions.

Answers

Answer:

Option (A)

Explanation:

According to the fossil succession, the rocks that are comprised of similar fossils that are found in different places are of the same age. This law enables a geologist to determine the relative age of the rock layers in an undisturbed sedimentary sequence.

In the given condition, considering the layers as 1, 2, and so on, from the bottom towards the top, the relative age of the layers could be determine, where, the layer 3 will be older than the layer 7 as the fossils embedded in the layer 3 were deposited earlier, and the fossils embedded in the layer 7 were deposited later, in terms of geological time.

Thus, based on the principle of fossil succession, the relative ages of the layers can be determined.

Hence, the correct answer is option (A).

Final answer:

The principle of original horizontality can be used to determine the relative ages of Layer 7 to Layer 3, as it affirms layers of sediment are originally deposited horizontally. Therefore, Layer 3 is likely older than Layer 7.

Explanation:

The principle that can be used to determine the relative ages of Layer 7 and Layer 3 is the principle of original horizontality. This principle states that layers of sediment are originally deposited horizontally, and then can be deformed into more complex structures. By this principle, we can say that Layer 3 is older than Layer 7, assuming no tectonic activities have occurred to disrupt the layers. The Principles of fossil succession, lateral continuity, and inclusions are also significant in stratigraphy studies, but for determining the relative ages of different layers, original horizontality is primarily utilized.

This concept is about companies taking responsibility for their product's environmental impact throughout its life cycle, in contrast to other market-oriented environmental policies.

Explanation:

An example of extended product responsibility is option c. the use of recycled wood products in the manufacture of new products. This concept entails that companies are responsible for the environmental impacts of their products throughout the product’s life cycle, including post-consumer use. This is in contrast to options like ecotourism, tradable emission permits, and soft loans for business planning, which are more aligned with market-driven environmental strategies or incentives for sustainable practices. The principle behind extended product responsibility is to encourage waste minimization and facilitate a closed-loop production system, ultimately leading to sustainable consumption and reduced negative environmental impacts.

Purchase of 'green' products, such as those using sustainably sourced timber or manufactured with recycled materials, represents a commitment to biodiversity conservation and often comes with higher costs. Consumers demonstrate their willingness to take on these costs for the sake of supporting environmentally responsible practices. Tradable emission permits, on the other hand, fall under market-oriented environmental policies, which serve to integrate the social costs of negative externalities into the economic activities that cause them.

In order to stimulate an effector in a toe, which pathway does a nerve impulse follow after it is initiated at a receptor?

A. sensory neuron -> interneuron -> motor neuron
B. motor neuron -> interneuron -> sensory neuron
C. interneuron -> sensory neuron -> motor neuron
D. None of these

Answers

Answer:sensory nuerone to internuerone to motor neurones

Explanation:

The sensory nuerone usually receive inputs from the receptors cells in the skin,organs,and other parts of the body.

These receptors send signals as action potential to the spinal cord to the brain.(CNS).

Synapse take place at the synaptic junctions, in the spinal cord with the internuerone.

The latter transmit the action potential to the motor neuron which synapse with the internuerone and transmita signal to the neuromuscular junction where it synapse with the muscels at the toe.

The action potentials causes influx of calcium ions and the relase of acetylcholine neurotransmitters for action potential to reach the toe muscles (effector)for contraction

The correct answer to the question is option A. sensory neuron -> interneuron -> motor neuron.

The correct pathway for a nerve impulse from a receptor to an effector in a toe is sensory neuron -> interneuron -> motor neuron. This pathway involves sensory neurons, interneurons, and motor neurons in a reflex arc. This process is fundamental for initiating quick, involuntary responses to stimuli.

Pathway of a Nerve Impulse to an Effector in a Toe

In order to stimulate an effector, such as a muscle in a toe, a nerve impulse follows a specific pathway after being initiated at a receptor. The correct pathway is:

Sensory neuron: Transmits information from the sensory receptors to the central nervous system (CNS).Interneuron: Relays the information within the CNS, typically the spinal cord, as part of the processing and decision-making steps.Motor neuron: Carries the impulse from the CNS to the effector (muscle or gland), causing a response.

Types of Neurons Involved

Sensory neurons: These neurons transmit information from sensory receptors to the CNS.Interneurons: These neurons are part of the CNS and are involved in the processing of information and decision-making.Motor neurons: These neurons send signals from the CNS to muscles or glands to initiate a response.

This pathway forms what is known as a reflex arc, which is a fundamental mechanism for reflex actions. For example, when you step on a sharp object, the pain receptors in your foot send a signal through the sensory neurons to the spinal cord, where interneurons process the signal and immediately send responses through motor neurons to pull your foot away.

Tryptophan is the signal molecule (effector molecule) that binds to the repressor. Determine which events lead to an increase in transcription. The trp operon is transcribed when a. the trp repressor dissociates from DNA. b. the trp repressor is inactive. c. Trp is present at high concentrations inside the cell. d. the trp repressor is bound to the operator. e. trp binds to the repressor. (a) Find a power series representation for the function. (Give your power series representation centered at x = 0.) f(x)=x/(10 x**2+1) sum_(n=0)^infinity (-1)**n 10**n x**(2n+1) sum_(n=0)^infinity (-1)**n (x**(2n+1))/(10**n) sum_(n=0)^infinity (-1)**n 10**n x**(2n) 10 sum_(n=0)^infinity (-1)**n x**(2n+1) sum_(n=0)^infinity (-1)**n 10**(n+1) x**(n+1) Correct: Your answer is correct.
