An example of mitosis at work is a leaf
turning yellow.
growing.
taking in carbon dioxide.
performing photosynthesis.
The right answer is Growing.
Mitosis is the cell division that allows an equal distribution of genetic information from an initial mother cell to two daughter cells while retaining the karyotype over the cell generations.
Mitosis will ensure - sometimes unfortunately - the good fulfillment of several phenomena:
1. embryonic development,
2. the general growth of organisms from birth to adult size,
3. the continued growth of certain organisms and / or organs; for example, trees, hair, teeth in ruminants, nails, ...
4. to renew dead cells; for example skin cells, red blood cells, ...
5. to ensure healing,
6. to preserve cellular identity during the development and renewal of cells belonging to the same organs, tissues, ...
7. As a result of disorders: cancers
An example of mitosis at work is growth. Therefore, option (B) is correct.
What is mitosis?Mitosis is the process of cell division where one cell divides into two identical daughter cells. Growth involves an increase in the number of cells and therefore, mitosis is essential for the growth of living organisms. During mitosis, the cell's nucleus divides into two identical nuclei, and then the cell splits into two daughter cells, each with a complete set of genetic material.
This process is essential for tissue repair, renewal, and growth in multicellular organisms. While photosynthesis and the uptake of carbon dioxide are important processes that occur in plant cells, they do not directly involve mitosis. Leaf turning yellow is an example of the aging process and does not involve mitosis.

To form amino acids from the main chemicals in Twinkies, what needs to happen? They need to be broken apart into individual atoms and rebuilt through RNA translation. They need to be broken apart into individual atoms and rebuilt through RNA translation. These compounds are already amino acids that need no further construction. These compounds are already amino acids that need no further construction. They can't be used to form amino acids, but are used in cellular respiration to create ATP. They can't be used to form amino acids, but are used in cellular respiration to create ATP. Bonds between their elements can be broken and reformed to construct amino acids. Bonds between their elements can be broken and reformed to construct amino acids.
Answer:
They need to be broken apart into individual atoms and rebuilt through RNA translation.
Explanation:
To form an amino acid the individual elements needs to be joined together to form a compound.
An amino acid is made up of nitrogenous bases they are joined together to form codon and are translated to amino acid
The process of translation in deoxyribonucleic (DNA) acid helps to translate the bases into an amino acid. This amino acids are said to be the buildings blocks of protein they perform specific function in the body system.
Which is one property of coal that makes it ideal for use in a power plant?
Answer:
it burns easily and it gives energy
Explanation:
The calorific power of coals varies from 2,000 to 7,000 kcal/kg, from anthracite and coal to lignite and peat.
The dry distillation of coal produces four fractions: ammonia, tar, natural gas, and coke. The latter (hard, resistant, and porous) is used in the metallurgy of iron and steel (steel).
Lignite is used mainly in thermal power plants to obtain electrical energy from it. Peat is used as a domestic fuel.
Answer:

It might have the negative effect of, after a failed hunt of a larger prey, it might have difficulty hunting after that, either by due to lack of energy or lack of food, which is basically the same
When hunting a larger prey the lion might have problems overpowering the prey and/or tackling it. When hunting smaller preys, it also has its drawbacks, sure, the lion might attack it and bring it down easily but it might be faster than said lion so it's always a gamble for a lion to hunt alone

This choice is true. Different molecules are used for different purposes.C. The molecules get completely eliminated by the rabbit as waste.
This is false. Nutrients and molecules are extracted and used in the body for processes like cellular respiration.D. The molecules are converted to energy only.
This is false. Some molecules will be used to produce ATP, but not all. Some will be used in other processes and eliminated as waste.The best answer is Choice B.
what is the difference between autosomes and gametes
Answer:
An autosome is any of the chromosomes, except the sex chromosomes, while is the sex cell.
Explanation:
Humans have 22 pairs of autosomes and one pair of sex chromosomes (pair number 23, made up of two X chromosomes in women and one X and one Y chromosome in men). Autosomes are numbered according to their relative size.
Gametes are the sex cells of multicellular and human organisms. They are haploid cells (that is, they contain 23 chromosomes, n), they originate by meiosis from germ cells (they contain 46 chromosomes, 2n).
During this process, germ cells mature and change shape until they become future gametes or cells with fertilizing capacity.
Where does the oxygen that plants add to the atmosphere originally come from

Why is the future climate response to increasing greenhouse gas
conzentrations uncertain?
Answer:
However, there are several aspects of climate change that remain more uncertain. These uncertainties stem primarily from uncertainties about future human actions, especially those that affect the sources and sinks of greenhouse gases, and uncertainties about how the climate system will respond to these actions.

Explanation:
As part of a laboratory experiment in his psychology course, Miguel is observing the activity of a recording electrode on the axon of a neuron. As an action potential
occurs what might Miguel observe?
A The axon will release neurotransmitters into the synapse.
B. The avon will remain at threshold potential as negative ions continue to flood the cell.
OC The decial charge of the neuron will go from positive to negative before returning to threshold potential.
OD. The curical charge of the neuron will go from negative to positive before returning to resting potential
Answer:
The correct answer is D
Explanation:
A resting neuron has a voltage across its membrane, which is referred to as resting potential. This resting potential is caused by concentration gradients of ions across the membrane. A neuron returns to the threshold potential by the movement of positive ions (especially K+ ions) through channels that stay open to exit the neuron.

Acetylcholine is found in the synapse between muscles cells and neurons. It can be broken down by the enzyme acetylcholinesterase. Which of the following describes what happens if acetylcholinesterase is inhibited?
Acetylcholine will continue to be activated.
Acetylcholine will be prematurely terminated.
Acetylcholine will lose specificity of the response.
Acetylcholine will be inhibited.
Answer:
Acetylcholine will continue to be activated.
Explanation:
When we inhibit acetylcholinesterase with an acetylcholinesterase inhibitor (AChEI) it will inhibit acetylcholinesterase from breaking down acetylcholine into choline and acetate. This will increase the level and the duration of the neurotransmitter in the CNS, autonomic ganglia, and neuromuscular junctions.

Answer:
One of them is the variance of the gene pool--in other words, the genetic adaptations plants and animals have help them to survive. That is where the phrase "survival of the fittest" comes from; if one is not genetically fit to survive in their environment, they will die off and their genes will not be added to the gene pool, making it easier for organisms with more fit genes to reproduce and add to the gene pool.
Another is the availability of resources. It is very hard for an organism to survive without food, water, and shelter. If the organisms of a species live in an environment with a lack of resources, they will die off, thus making them unable to reproduce and therefore go extinct.
Also, the presence of predators makes it difficult for a species to survive. Predators preying on prey make prey poulations go down and predator populations go up. However, going back to the gene pool, many organisms have adapted to hiding from predators with means such as camouflage or burrowing.
Finally, the general conditions of their environment. This one is self-explanatory. For example, you would not expect to find a polar bear in the desert or a cactus in the Arctic. The conditions are simply not right for their survival and they will die off. This is also why birds migrate--they need to go somewhere warm in the winter to keep themselves warm!
