Answer:
B. The mutation results in a new, dominant allele
C. The mutation occurs in a gene that controls development and alters differentiation of a cell type during development.
D. The mutation occurs in a codon and alters the function of the final protein
Explanation:
All the above things will change the <u>ultimate expression</u> or phenotype by altering the proteins. Choices B, C, and D will all change the outer functioning.
Choice A only affects the rate of transcription, so it may go faster or slower, but the end product will be the same.
This part that doesn't look like it's one of the choices ("The mutation occurs in a portion of an intron not responsible for exon splicing.") would not affect phenotype, because introns are removed before the RNA is sent out.
Choice E says that the amino acid sequence is unchanged, meaning the protein final product will be the same and the expression will not change.
Two examples of how the biosphere supports life is by reducing the amount of harmful radiation to reach the surface of the earth. It also gives oxygen for animals to breathe
<span>B- tree > insect > frog> snake> hawk
The food chains are represented by organisms interconnected by red arrows that point in the direction of the one that's eating. So, the relation that is explicit by the arrow is that the organism from where the arrow departs is eaten by the organism where the arrow is pointing towards to. So, the food chain that can be observed accurately in the food web is: the tree is eaten by the insect, the insect is eaten by the frog, the frog is eaten by the snake, and the snake is eaten by the hawk.

<span>The nurse should tell the patient that eating a variety of healthy food is the best source of vitamins<span>. This is should be told by the nurse in a nice and emphatic manner, especially in this case wherein patients diagnosed with HIV are particularly emotionally sensitive. While this is true, the nurse should not advise the patient to stop taking his or her supplements; especially being diagnosed with HIV, his or her immune system is very frail and needs more than the usual nutrients compared to the normal population. </span></span>
Answer:
Meiosis
Explanation:
Meiosis is one of the two types of divisions that cells usually undergo. However, meiosis is unique to sexually-reproducing organisms. Meiosis is the cell division which results in daughter cells with a reduced number of chromosomes (by half). Meiosis is used to produce gametes in sexually reproducing organisms.
According to the question, Labrador retriever contains 78 chromosomes in each of its muscle cells, which is a somatic cell. Since Labrador retrievers are sexually reproducing organisms, a male one will produce gametes (sperm cells) via the process of meiosis. At the end of the meiotic process, sperm cells with 39 chromosomes each will be produced.
