1. Phenotypes that decide the decide the development plan of the body do not vary in a population of organisms. Example, the segmentation of the body (number of hands, legs, ears, eyes, etc.).
2. Phenotypes that vary in a population are the eye color, hair color, hair growth, body size, body build, cold tolerance, skin color, etc.
3. Most of the phenotypes have a genetic basis, example, the colorblindness trait that is X linked inherited. But some phenotypes vary epigenetically, e.g., differences in body features of twins.
4. Yes, environment influences the phenotypes. Twins have a genetically identical DNA yet they have minute differences in their skin color, eye color, body build, etc. Such differences arise when the environment differently affects the gene regulation within the body of the twins.
The answer is B) whether the mutation makes some lizards more fit for their environment than other lizards.
<span>If a mutation introduces a new skin color in a lizard population and that </span>mutation makes some lizards more fit for their environment than other lizards then the frequency of <span>the new allele will increase. For example, if a mutation causes some dark skin color which can help some lizards to survive. The more lizards with dark skin color will survive, and after some time, the frequency of the new allele will increase.</span>
Answer: Chemotherapy kills the leukemia cells, but releases the content of the cell into the bloodstream which cannot be filtered at once by the kidney.
Explanation: Chemotherapy can be defined as the use of drugs to treat cancer. The drugs that is given in chemotherapy flows through the bloodstream to reach all over the body.
This treatment method is only used for the people suffering from acute lymphocytic leukemia. Because of its potential side effect it cannot be used for the person who is already sick.
The chemo cells are killed by leukemia cell and the contents are released into the blood stream which are not filtered by the kidney at once. Excess amount of these substances in blood can adversely affect the nervous system and heart.
This is how the chemotherapy enhances the effects of leukemia.
I can certainly see how this is likely to be a science book. With the latest photographic technology scientists have photographed everything from star nebulas, space gases, to exoskeletons of creatures, flowers, sun flares, waves in motion, inside cells, etc. so yes absolutely!
Answer:
Disconformity
Explanation:
Disconformity is the breaking end between non sedimentary and sedimentary rocks. It is when parallel layers between sedimentary rocks have no contacts with each other which indicate period of erosion or non disposition.
