Answer:

Mitosis is the the point in the cell cycle associated with division or distribution of replicated genetic material to two daughter cells. During mitosis the cell nucleus breaks down and two new, fully functional, nuclei are formed.

Explanation:

Answer:

In eukaryotic cells, or cells with a nucleus, the stages of the cell cycle are divided into two major phases: interphase and the mitotic (M) phase. During interphase, the cell grows and makes a copy of its DNA. During the mitotic (M) phase, the cell separates its DNA into two sets and divides its cytoplasm, forming two new cells.

Rosalind Franklin established that the molecule existed in a helical configuration and, more significantly, identified the density of DNA. Her efforts to improve the clarity of DNA molecule X-ray patterns.

Some would argue that Rosalind Franklin received unfair treatment despite having made a significant contribution to the understanding of the double helix structure of DNA. Brenda Maddox, a biographer, dubbed Franklin the "Dark Lady of DNA" because one of her employees once disparaged Franklin.

Rosalind Franklin, PhD, the brilliant and trailblazing scientist whose Photo 51 discovered the double helix of DNA, was honored with a dedication to our university in 2004. It is served as the basis for Francis Crick and James Watson's 1953 hypothesis that DNA is a double-helix polymer.

Explanation:

polar bear depend on ice so if it gets really hot out of a sudden the melt will melt away and it would be harder for them to live. and for grizzly bears if gets cold all out of the sudden the rivers where they get food turns to ice they'll food which is what they depend on (fish) will die and without food they'll die too.

Grizzly and polar bear evolution may be affected by climate change due to habitat loss, adaptation, competition, and interbreeding, all of which will lead to the evolution of polar bears.

As the climate changes, the habitats that these bears depend on may shift or disappear, such as as the Arctic sea ice melts and polar bears are forced to spend more time on land, where they have less access to food; as grizzly and polar bears are closely related and can interbreed, producing hybrid offspring that could potentially alter the genetic makeup of both species; etc. Both grizzly and polar bears may be able to adapt to changing environmental conditions, and grizzly bears may outcompete polar bears for resources, which could further threaten polar bear populations.

Hence, grizzly and polar bear evolution may be affected by climate change due to habitat loss, adaptation, competition, etc.

Answer:

D. New DNA is synthesized as the chromosomes are replicated

Ionizing radiation, including X-rays and gamma rays, has high energy and can penetrate deeply. It ionizes molecules, making them highly reactive, which can cause replication errors in DNA. Non-ionizing radiation, such as UV light, carries less energy and does not penetrate as effectively. Bacteria possess photoreactivating enzymes that can repair damage caused by UV light by splitting the dimers. This repair process may occasionally result in errors, serving as another source of mutation.

Ionizing radiation such as X-rays and gamma rays cause various mutations in DNA. They ionize molecules and produce ions that join bases in DNA, resulting in replication errors. In addition, the radiation may cause breakage in the sugar-phosphate backbone of DNA, leading to physical breaks in the chromosome.

Bacteria do not have any mechanisms to repair such damage caused by ionizing radiation. When the damage is substantial, the bacterial cell's DNA repair machinery may not be capable of repairing the damage, leading to cell death.

Nonionizing radiation such as UV light does not have the same amount of energy or effectiveness as ionizing radiation. However, it may cause thymine dimers to develop in the DNA strand. If these dimers are not repaired, DNA replication and transcription will not occur correctly.

Photoreactivating enzymes are present in bacteria and other organisms that can repair damage caused by UV radiation by dividing the dimers. Occasionally, this repair process can result in mutations. Nucleotide excision repair is another mechanism that bacteria use to repair damage caused by UV radiation. In this mechanism, the thymine dimer is removed and a new DNA strand is synthesized.

Bacteria use various mechanisms to repair the damage caused by radiation, but they do not have any means to repair severe DNA damage caused by ionizing radiation. UV light can be repaired by photoreactivation enzymes or nucleotide excision repair mechanisms.

Answer:

X and Y

these ur answer sir

Answer:

The primary mechanism by which a cell gets rid of excess carbon dioxide (CO2) is through a process called respiration or cellular respiration. In cellular respiration, cells break down glucose and other organic molecules in the presence of oxygen to produce energy in the form of ATP (adenosine triphosphate), along with carbon dioxide and water as byproducts.

Once carbon dioxide is generated during cellular respiration, it diffuses out of the cell and into the surrounding tissues and fluids. From there, it enters the bloodstream and is transported to the lungs. In the lungs, carbon dioxide is exchanged for oxygen through the process of gas exchange during breathing. Oxygen is taken up by the red blood cells, while carbon dioxide is released into the air as we exhale.

In summary, cells eliminate excess carbon dioxide by releasing it into the bloodstream, where it eventually reaches the lungs for exhalation.

hope that helps :)

Answer:

In small populations it unlikely genetic drift will occur but in large populations it’s very likely

Explanation:

Depending on population size there is different amounts of genetic variation. That will give different amounts of opportunities to have genes staying alike or becoming different.

In a small population, genetic drift will occur but in a large population, it is likely to be that.

The genetic variation depends upon the size of the population. Thus giving it the amount that the genetic variation will cause genetic changes in the population.

It is the variation dye to genetically changes in an organism. It changes allele frequency also leading to several changes in genetics.

Thus it is clear that changes in allele frequencies did you observe in the population in the short turf habitat and in the rough vegetation habitat by genetic variations.

Lateral inhibition refers to the phenomenon whereby the activation of sensory receptors in the center of a stimulus (like a pencil eraser) suppresses the receptors excited at the stimulus's outer borders.

This is a process that occurs within the nervous system and helps to sharpen the perception of stimuli by enhancing the contrast between the center and the surrounding area.

This mechanism helps to filter out sensory information that is not relevant to the task at hand, making it easier to perceive and respond to important stimuli. Lateral inhibition plays a role in many aspects of sensory processing, including vision, touch, and hearing, and is essential for normal perception and behavior.

Models are important in science because a model is a representation of an idea or an object or systems that could be used to describe something that cannot be experienced directly

Answer:

Models allow the scientist to describe objects that are too large or too small to be seen normally, things that don't exist anymore, things that have not been created, and events that occur too slowly or too quickly to be seen. Models also communicate ideas that might be difficult to describe otherwise.

If a human can continuously eat without feeling full, they might be in deficit of the hormone leptin, option 6 is correct.

Leptin is primarily produced by fat cells and acts as a satiety hormone, signaling to the brain that the body has sufficient energy stores. It helps regulate appetite and energy balance by suppressing hunger and increasing energy expenditure. When leptin levels are low or the body becomes resistant to its effects, the brain doesn't receive the signal that the body is satiated, leading to excessive food intake and a lack of feeling full.

While the other hormones listed, such as glucose, neuropeptide Y, testosterone, glucagon, and PYY, may play a role in appetite regulation and energy balance, leptin is specifically associated with signaling fullness and satiety. Its deficiency or resistance can disrupt the normal feedback loop between the body and the brain, resulting in continuous eating without feeling satisfied, option 6 is correct.

The imaging technique that doctors will likely use to assess both the structure and blood flow of Stephen's brain is called functional magnetic resonance imaging (fMRI).

fMRI uses a strong magnetic field and radio waves to produce detailed images of the brain's structure, similar to a traditional MRI. However, it also measures changes in blood flow to different areas of the brain, which indicates neural activity in those areas. By analyzing these changes in blood flow, fMRI can provide information about which areas of the brain are active during different tasks or in response to different stimuli.

In Stephen's case, fMRI can help doctors identify which areas of the brain are impacted by the tumor and how they are functioning. By comparing images of Stephen's brain with and without the stimulation, doctors can assess the effects of the tumor on the blood flow and identify areas of the brain that are affected by it.
