Specific heat is the amount of heat required to raise the temperature of a material by 1°C per what unit?
A. volume
B. joule
C. mass
D. pressure
E. density
Answer:
The answer would be C: Unit of Mass
Answer:
C. mass
Explanation:
Specific heat is defined as the amount of heat energy required to elevate the temperature of a material by 1°C per unit mass.
It is a physical property of a material. The standard international unit of heat capacity is joule per kelvin per kilogram (J/K/Kg).
If a substance has a high specific heat then it simply means that it will take very long to get heated but once heated it will take very long time to cool down either.
Water has highest specific heat.

In which area of the neuron is an action potential initially generated?
Answer:
(C). Membrane potentials above threshold at the hillock will open voltage-gated Na+
Explanation:
The action potential in a neuron is initially generated in an area called the axon hillock, which integrates incoming signals and decides whether or not to fire an action potential.
Explanation:The action potential in a neuron is initially generated in an area called the axon hillock. This part of the neuron is responsible for integrating incoming signals from synapses and deciding whether or not to fire an action potential. As the action potential travels down the neuron's axon, it stimulates other neurons and continues the cycle of information transmission. For instance, when you touch a hot surface, the sensation is relayed as action potentials from the sensory neurons in your finger all the way to your brain.

Benito is doing research on the effects of Florida's elevation on its climate. His notes include the following:
1. The average elevation of Florida is 30 m above sea level.
2. The highest point in Florida is Britton Hill, which is 105 m above sea level.
3. The change in temperature from 0 m to 1,000 m is 7 °C.
What can Benito conclude about the effects of Florida's elevation on its climate?
A.) Florida typically experiences cold temperatures and temperature changes within a narrow range.
B.) Florida typically experiences cold temperatures and temperature changes within a broad range.
C.) Florida typically experiences warm temperatures and temperature changes within a narrow range.
D.) Florida typically experiences warm temperatures and temperature changes within a broad range.
OPTION C.
Florida generally experiences warm temperatures due to its low average and highest elevations. The change in temperatures is also low, which means a narrow range of temperature variance.
Explanation:Based on the information provided, Benito can conclude that Florida typically experiences warm temperatures and the temperature changes within a relatively narrow range. This can be inferred from the fact that Florida's average and highest elevations are relatively close to sea level, and therefore, the effect of elevation on temperature would be minimal. As the temperature drop rate is 7°C per 1000 meters, the temperature difference within Florida's elevation range (from 0m to 105m) would be slight.

Residential construction is expanding in Florida, the expansion has caused fragmentation of habitats, one of the results of the increased construction is a decrease in the number of large predators such as the coyote, black bear and pool panther, which will be the most immediate local result of this fragmentation? 1)large predators will become extinct 2)decrease in middle sized predators 3)increase in population of top carnivores 4)increase in population of prey species
Answer: 1 ) large predators will become extinct
Explanation: Due to the expansion of residential construction in Florida these large predators will have no place to live and eventually die, leading to an extinction.
Answer: 1) Large predators will become extinct.
Explanation:
A predator is a organism which kill other organism to obtain it as food. The organism which is killed is prey. The predators are carnivores organisms, which means they are flesh eating organisms.
According to the given situation, the residential construction in Florida is the limiting factor for the growth and abundance of predator population. This has resulted in the decrease in the population of predator species. Hence, many predator species will extinct immediately due to habitat fragmentation.

A.the birds were not all finches
B.the birds evolved at different times
C.the birds had different diets
C. The birds had different diets. The bird's beaks evolve depending on their diet!
Sunny~ ☺
Answer:
c. the birds have different diets
Explanation:
The research that Darwin had at Galapago´s Islands, brought up several questions about why are living species the way they are. As part of the theory of Natural Selection, Darwin supported that the physical characteristics of the individuals are strictly related with their function. For example, the shape of the beak of the finches, which is a consequence of evolution, has a strict relation with the type of diet they have and as a consequence, the adaptation they will have in their environment.

Which of the following statements about amino acids is INCORRECT?
A turn or kink in a protein is more likely to be induced by a proline than by a glycine.
The more glycines that are found in a polypeptide's primary sequence, the more flexible the backbone of that polypeptide.
The bridge between cysteines, which connects parts of a protein, is a stable but noncovalent interaction.
Not every amino acid is asymmetric.
At typical cellular pH, the R groups of basic amino acids are positively charged.
Answer:
The answer is: The bridge between cysteines, which connects parts of a protein, is a stable but noncovalent interaction.
Explanation:
Hope my answer has helped you!
Final answer:
The incorrect statement is that the bridge between cysteines in proteins is a noncovalent interaction; it is actually a covalent bond known as a disulfide linkage, crucial for protein tertiary structure stabilization.
Explanation:
The incorrect statement among the choices provided for amino acids is that the bridge between cysteines, which connects parts of a protein, is a stable but noncovalent interaction. In truth, the bridge between cysteine residues is formed by a covalent bond known as a disulfide linkage. This link is a result of the oxidation of two cysteine molecules, which combine to form cystine, and it is significant in stabilizing a protein's tertiary structure.
A turn or kink in a protein is indeed more likely to be induced by a proline than by a glycine, due to proline's ring structure. Glycine, having a single hydrogen atom as its side chain, is small and allows flexibility in the protein structure, making the backbone of the polypeptide where glycines are present more flexible. Not every amino acid is asymmetric; for instance, glycine is not chiral. At typical cellular pH, the R groups of basic amino acids such as lysine and arginine are indeed positively charged.
What is the main sugar used by cells for energy?
Answer:
The answer is GLUCOSE.
Explanation:
Glucose is the main sugar used by cells for energy. Glucose is derived from the digestion of carbohydrates. In humans, glucose is usually absorbed into the blood from the small intestine, the blood then carry the blood around the body, allowing each cell to have access to the glucose it needs.
If the quantity of glucose in the blood is more than needed per time, the body usually store the excess glucose as glycogen, the glycogen will be turned to glucose and release for cell use when the quantity of sugar in the blood is low. In the absence of glycogen, other macro nutrients such as lipids and proteins can also be converted to glucose via gluconeogenesis when the concentration of glucose in the blood is low.
The cells oxidize the glucose and convert it to energy in form of ATP, which they use to carry out their life activities.
The main sugar used by cells for energy is glucose. It can be stored as glycogen in the body or it is converted into fat if in excess. During cellular respiration, it helps to form ATP, the cells' energy currency.
Explanation:The main sugar used by cells for energy is glucose. This simple sugar, a monosaccharide, is an important energy source for many organisms. Carbohydrates, such as sugars, are the most common source of energy for the body, broken down during digestion into simpler monosaccharides like glucose and fructose.
Once glucose is in the body, there are a series of endocrine control mechanisms that regulate its concentration in the bloodstream. Excess glucose can either be stored in the liver and skeletal muscles as a complex polymer called glycogen, or it can be converted into fat in adipose cells or adipocytes.
During cellular respiration, energy is released from glucose. This energy helps to form adenosine triphosphate (ATP), which is like the currency that cells use for energy. Photosynthetic plants synthesize glucose using carbon dioxide and water, and the glucose is then used for their energy requirements. Any excess synthesized glucose is often stored as starch, which can be broken down by other organisms that feed on plants.

d. activated complex.
Answer:
d. Activated complexExplanation:
❣️个 jess bragoli 个❣️#keep learning!!The short-lived structure formed during a collision in a chemical reaction is known as the activated complex or transition state, which is a highly unstable arrangement of atoms with a brief lifespan.
Explanation:A short-lived structure formed during a collision in a chemical reaction is known as the activated complex or the transition state. This occurs when reactant particles collide with both proper orientation and sufficient energy. The activated complex is an unstable arrangement of atoms that exists at the peak of the activation energy barrier and has a very brief existence, around 10-13 seconds.
It can either revert to the original reactants or continue on to form products. This state is typically undetectable by standard analytical instruments, although sophisticated spectral measurements can sometimes observe these transition states.

Two pea plants with yellow peas are crossed. Most of their offspring have yellow peas, but about 25 percent of the offspring have green peas. For pea color, yellow is the dominant trait and green is the recessive trait. What does this tell you about the two parent plants?
A. The parent plants have only dominant alleles for pea color.
B. The parent plants are heterozygous for pea color.
C. Pea color follows an incomplete dominance pattern of inheritance.
D. The parent plants are homozygous for pea color.
Answer:
B. The parent plants are heterozygous for pea color.
Explanation:
If both the parent plants had only dominant alleles for pea color as described in A, all of their offspring would be yellow (dominant). We know that pea color does not follow an incomplete dominance pattern because the question states that yellow is dominant and green is recessive; there is no intermediate mixture of these colors as a trait. If the parents were both homozygous, then their offspring would either be all yellow or all green. If we do a punnett square with 2 heterozygous parents, we will see that one out of 4 (25%) offspring will indeed be green.
Answer:
B. The parent plants are heterozygous for pea color.
Explanation:
Select the correct answer. A chestnut-colored horse mates with a white-colored horse to produce a brown and white spotted offspring. What is the type of inheritance pattern?
Answer:
codominance
Explanation:
there is no blending of the two colours, both are shown equally and expressed in the proper colours not blended therefore they are both dominant and it is codominance
Answer:
codominance
Explanation:
Codominance is a situation where the alleles of a gene are active, that is, there is no dominance relationship between them, so the two alleles are expressed, as is the case with the horse shown in the question above.
Generally, in the formation of a phenotype, one allele stands out against the other (remember that every gene is formed by a pair of AA, Aa or aa alleles). For the father's eye color to be repeated in his son, for example, it is necessary that the gene that determines this characteristic has a dominant allele. The other allele of this gene in the child will be the recessive allele. It happens, in some cases, that the two alleles (recessive or dominant) have the same dominance relation over each other and there is a mixture of phenotypes of both. A beautiful example of this mixture is the birth of horse species with a spotted coat.
Which activity occurs when a flowering plant reproduces?
Hello There!
Flowering plants reproduce through the process called pollination. There are many different types of pollination
Answer:
Flowering plants require the formation of reproductive structures and pollination.
Explanation:
For flowering plants to reproduce, first the reproductive structures have to form (pistils and stamens) and then the pollen has to be taken from the first flower to the second or where the fertilization will happen. There are several ways to pollinate, including insects, or bigger animals like bats. After the animal is taking the pollen to another flower, it is fertilized and starts to transform into a fruit, where, later the seeds will also be carried by animals.

A. All of the different population of species in one geographic area.
Explanation:
Biological community consisting of living organisms in different locations. For example, a forest trees and undergrowth plants, inhabited by animals and rooted in soil containing bacteria and fungi, constitutes a biological community.
A biological community consists of the biotic and abiotic items in the ecosystem.
What is biological community?The term "biological community" refers to a group of variables that includes both biotic and abiotic variables. The biological community is defined by the way the two components interact.
Trees, rocks, and soil are examples of abiotic factors that interact with biotic factors like plants and animals. The biological community functions in this manner.
Ecological succession is the process by which a population gradually alters its genetic composition. The community is therefore dynamic since it evolves over time. Communities can be huge with many species populations or tiny with few species.
Their interactions, known as interspecific interactions, have an impact on a community's composition, distribution, and abundance, or the quantity of each species present.
