What example involves a cell membrane receiving and sending messages?
An example that involves a cell membrane receiving and sending messages is when the cells of an organism tell each other when predators are near. The membrane is very helpful in communication in the body. This question was already asked two times in Brainly, so if you want to go into more depth, I recommend you look at the answers there. :)
I hope this helps! :)
Answer: The signals are transferred from the brain to the various parts of the body and from the body to the brain.
Explanation:
The transmission of the signals though neurons can be defined as an example of cell membrane receiving and sending messages.
Any stimulus from the outer environment is transferred to the brain via signal transduction method and then response is generate as a feedback of the stimulus.
What three processes take place in the digestive system?
ingestion, propulsion, mechanical or physical digestion, chemical digestion, absorption, and defecation. The first of these processes, ingestion, refers to the entry of food into the alimentary canal through the mouth.
The digestive system performs three main processes: digestion of food, which includes mechanical and chemical breakdown, absorption of nutrients primarily in the small intestine, and elimination of solid food waste through defecation.
Functions of the Digestive System
The digestive system is integral to the process of obtaining nutrition and energy from food. It involves a multi-step process, which includes several distinct but interconnected functions. Three primary processes take place in the digestive system:
Digestion of Food: This is the mechanical and chemical breakdown of food into smaller components that can be absorbed into the bloodstream.
Absorption of Nutrients: After digestion, the small intestine absorbs nutrients from the food and transfers them to the bloodstream, where they can be distributed and utilized by the body.
Elimination of Solid Food Waste: Finally, the body expels undigested and unabsorbed food materials along with waste products, a process culminating in defecation.
Mechanical digestion starts with mastication (chewing) in the mouth, while chemical digestion involves enzymes breaking down complex molecules. Most absorption occurs in the small intestine, but the large intestine (colon) also plays a role in absorbing water, some vitamins, leftover salts, and in the formation of feces.

A)
how heavy Earth is
B)
how fast the Sun spins
C)
how many planets there are
D)
how big the Solar System is
ANSWER: C: HOW MANY PLANETS THERE ARE
EXPLANATION: A model cannot show accurate weight. The Sun doesn't spin, and the Solar System cannot be accurately measured in a model
Answer:
Option C, How many planets there are
Explanation:
The model of solar system presented here is a static model which means it can only display the static characteristics. Therefore, this model only presents the number of planets in the solar system.
In this model, weight of earth and size of the solar system can be resented through relative scale of weight such a one gram of weight representing 100000 Kg or 1cm representing 1 light year of distance but since no specific detail is given regarding any relative scale , thus option A and D are not the correct choice of answer
Option B is also not a correct choice of answer as speed is a dynamic characteristics and it cannot be represented in a static model.
What two main biological processes are responsible for the cycling of oxygen
Answer:
Main biological process are photosynthesis and respiration, responsible for the cycling of oxygen.
Explanation:
The two main process are responsible for the cycling of oxygen are photosynthesis and respiration. They are interconnected with the water cycle and carbon cycle.
The oxygen is the cycle that helps to move oxygen from biosphere, lithosphere and atmosphere. How the oxygen cycle takes place:
Photosynthesis: During the day, plants take energy from the sun, Carbon-dioxide from the air and water from the to make their food in the presence of sunlight. Their food is : Glucose. Oxygen is released into the air as a by-product.
Respiration: The oxygen is released by the plants used by animals, humans and other organisms that is breathing. During respiration, organism take in oxygen and release carbon-dioxide into the air.
Repeat: This carbon-dioxide is again take up by plants for the photosynthesis.

TRUE OR FALSE
Nerve cells, or neurons, carry messages in one direction.
False!
Neve cells send messages from your brain and to your brain.
That's why you feel pain, etc
Final answer:
Nerve cells, or neurons, carry messages in one direction, which is true. They are designed to send signals precisely from the cell body through the axon to another neuron's dendrites, and although interneurons carry impulses in both directions, they adhere to the one-way system of nerve impulse transmission in the nervous system.
Explanation:
The statement that nerve cells, or neurons, carry messages in one direction is TRUE. Neurons are the main functional units of the nervous system and have a unique structure that enables them to transmit nerve impulses effectively. A neuron's anatomy comprises a cell body, an axon, and dendrites. Signals originate in the cell body, travel down the axon, and are transmitted to another neuron's dendrites across a synapse using neurotransmitters. This unidirectional transmission is essential for the precise flow of information in the nervous system.
Furthermore, different types of neurons, such as interneurons, specifically carry nerve impulses back and forth within the brain and spinal cord, often between sensory and motor neurons. This exchange allows for complex reflexes and neural processes. Though interneurons communicate in both directions, they do so within their structure, respecting the overall one-way traffic rule of neuronal communication.
Given the sequence of DNA nucleotide bases TAGTAGTAG, give the complementary strand of mRNA produced during transcription.
A) AAGGUAGUA
B) AAUCGGAAC
C) AUCAUCAUC
D) GAGGAGGAG
The answer I believe is C. T turns into A. A turns into U, and so on
Answer:
C) AUCAUCAUC
Explanation:
The mRNA is formed with nitrogenous bases complementary to the nitrogenous bases that the DNA strand (used as a template for the creation of RNA) possessed. However, RNA does not have the Thymine nitrogen base, instead the Uracila nitrogen base is placed. Accordingly, if the DNA base sequence used as template is adenine, thymine, guanine and cytosine (ATGC), the mRNA sequence will be uracil, adenine, guanine and cytosine (UAGC).
In the case of the above question, the DNA base sequence was TAGTAGTAG, from this we can say that the mRNA created from that DNA will have its AUCAUCAUC base sequence.

Meiosis is important because it generates genetic diversity and variation.
Explanation:
Meiosis has its significance generates by recombination and sexual reproduction genetic diversity. It also repairs genetic defects in germline cells.
It helps maintain the perpetuity of the germline, by the elimination of defective meiocytes possible or by a process of renewal involving the removal of faulty protein and protein molecules.
Thus, Meiosis is important because it generates genetic diversity and variation.
Which of these pollutants is biodegradable?
food waste
mercury
methane
lead
Answer:
Food waste
Explanation:
Food waste is an organic compound, unlike the other choices. Organic compounds are biodegradable because living organisms, such as decomposers, have evolved mechanisms of breaking down these large carbon-based compounds/polymers into smaller molecules for energy. Food waste is therefore easily recycled into the environment.
The others do not have naturally occurring organisms to break them down or reduce them. They would, therefore, accumulate in the environment. This is exactly what is happening to plastc pollution. Accumulation of plastic in the environment is due to fact that they are not broken down into simpler molecules by any naturally occurring bacteria or organisms in the environment.
Food waste is the biodegradable pollutant among the options, as heavy metals like mercury and lead accumulate in the environment and organisms without breaking down naturally.
Out of the options provided (food waste, mercury, methane, lead), food waste is the pollutant that is biodegradable. Biodegradability refers to a substance's ability to break down in the environment due to natural processes. Heavy metals such as mercury and lead do not biodegrade and instead can bioaccumulate in living organisms, posing significant health risks and environmental concerns. Methane, while a naturally occurring gas, is not typically referred to as biodegradable, as it does not break down into simpler substances through biological agents but rather dissipates over time through photochemical reactions in the atmosphere.
A women homozygous for blood type B marries a man that is heterozygous for blood type A. State the possible phenotypic ratio of the offspring?
The possible phenotypic ratio of children from a woman with homozygous type B blood and a man with heterozygous type A blood is 1:1, where half of the children will have blood type AB and half will have blood type B.
A woman who is homozygous for blood type B (genotype IBIB) marries a man that is heterozygous for blood type A (genotype IAi). To determine the possible phenotypic ratio of their offspring, we can set up a Punnett square. Since the woman is homozygous, all her eggs will carry the IB allele. The man, being heterozygous, can produce sperm with either the IA or i allele.
When we cross these genotypes, there are two possible outcomes for their children with respect to the ABO blood group:
The offspring receives IB from the mother and IA from the father, resulting in blood type AB.
The offspring receives IB from the mother and i from the father, resulting in blood type B.
Thus, there is a 1:1 ratio of phenotypes: half of the children will have blood type AB and half will have blood type B.

Arrange the trophic in ascending order starting from the base of the ecological pyramid of energy and increasing to the top.
• Secondary consumers
• Herbivores
• Producers
• Apex predators
Producers, herbivores, secondary consumers, apex predators
The ecological pyramid of energy is organized in ascending order as Producers, Herbivores (Primary consumers), Secondary consumers, and Apex predators (Tertiary and other high-level consumers).
In an ecological pyramid of energy, organisms are arranged in a linear sequence based on their roles as producers and consumers, known as trophic levels. The ascending order of these levels, starting from the base and moving up to the top, is as follows:
Producers
Herbivores (Primary consumers)
Secondary consumers
Apex predators (Tertiary and other high-level consumers)
At the base are the producers such as plants and phytoplankton, which are able to create their own food through photosynthesis. The next level up consists of the primary consumers, which are herbivores that feed on these producers. Secondary consumers typically are carnivores that consume the primary consumers. Finally, apex predators occupy the top of the pyramid, being tertiary or higher-level consumers that have no natural predators.

How do The thickness and darkness of glass affect the amount of light that is transmitted
The thickness and darkness of glass affect the amount of light transmitted due to changes in speed of light (refraction), absorption, and interference of light. Thicker and darker glasses reflect and absorb more light, reducing the light transmission. The interference between light reflected from the top and bottom surfaces of the glass also affects light transmission.
Explanation:The thickness and darkness of glass can influence the amount of light that is transmitted through it. This phenomenon is linked to the interactions of light waves and the refractive index of the material. The glass can be analyzed as a thin film - a structure possessing a thickness smaller than a few times the wavelength of light. As light strikes the surface of the glass, it is partially reflected and partially refracted, a process that depends on the thickness of the film and the indices of refraction of the various media.
When light travels through a physical medium, its speed is altered, which can cause the light to change direction. This is called refraction. If we take into consideration a thicker or darker glass which might potentially absorb more light, the transmitted light will be less. Essentially, the thicker the glass or the more opaque it is, the less light transmission occurs. This is due to increased reflection and absorption of the light waves.
The other important aspect to keep in mind is that there can be interference of light that has been reflected from both the top and bottom surfaces of the glass. This interference can either be constructive or destructive, which depends mainly on the thickness of the glass and can affect the amount and color of the light transmitted.

which part of the molecule holds the energy waiting to be released
Answer:
Energy awaiting to be released is held in the bond between the 2nd and the 3rd phosphate groups of ATP.
Explanation:
The ATP molecule has an adenosine molecule that is made up of three phosphate groups.
Energy produced during respiratiojn is stored in the bond between the second ans the third phosphate groups, when needed to be used by the cell, ATP looses its third bond exposing the stored energy for use.
Through the above process, it goes back to the ADP form that combines with a third phosphate group to store energy.
All of the following characteristics are used to classify living organisms EXCEPT –
Living organisms are classified based on their shared characteristics: order, sensitivity, reproduction, adaptation, growth and development, regulation, homeostasis, and energy processing. All forms of life, despite their diversity, share these characteristics, which have developed through evolution. Additional information would be needed to identify a characteristic that is NOT used for this classification.
Explanation:Biologists define living organisms by multiple shared characteristics including order, sensitivity or response to stimuli, reproduction, adaptation, growth and development, regulation, homeostasis, and energy processing. When all these characteristics are observed together, they serve to indicate life. However, the classification of living organisms does not involves their external appearance or habitats alone, as it encompasses other aspects relating to their fundamental function and structure like genetic make-up, cell structure, how they reproduce, and how they secure energy to function.
Despite the vast diversity among living organisms, such as plants, animals, fungi, bacteria, and archaea, they all share these defining characteristics. The diversity seen today is the result of evolution, where less diverse ancestral organisms have evolved into the varied forms we see in present times.
However, the question presented asks about a characteristic that is NOT used in the classification of living organisms. Since all mentioned characteristics; order, sensitivity, reproduction, adaptation, growth and development, regulation, homeostasis, and energy processing are indeed used, we would need more options or information to definitively identify one not used in the classification process.
