Answer:
Inducible
Explanation:
When a gene is expressed only under certain conditions such as the presence of an inducer in the environment to inactivate the repressor, the gene expression is said to be inducible. Here, the presence of substance Y is required as it serves as an inducer by inactivating the repressor protein. When the repressor protein is inactivated, RNA polymerase is able to express the gene. This is an example of inducible gene expression. For example, the presence of lactose is required for the expression of genes of the lac operon.
Cells differentiate in the womb.
Answer: the volume of oxygen increases
Explanation:
As light intensity increases which is the distance between the light and the plant the volume of oxygen or the rate of bubble production increases. This shows that the rate of photosynthesis increases with light intensity
Higher light intensity means more light called photons are heading to leaves as you increase from low light intensity to higher light intensity the rate of photosynthesis will increase because there is more light available
Answer:
lysosomes
endoplasmic reticulum
vacuoles
mitochondria
cytoplasm
golgi apparatus
ribosomes
chloroplast
Explanation:
in order of the functions listed
Answer: A (AA x aa)
Explanation:
In option (A) both of the parent mussels are homozygotes, for alleles "a" and "A" respectively. Therefore, every single one (100%) of their offspring would be expected to be Aa heterozygotes. Combinations (B) and (D) yield a lower proportion of heterozygotes (50%), and combination (C) yields none at all. Punnett squares follow:
(A)
<u> | A A </u>
<u>a | aA aA </u>
<u>a | aA aA </u>
<u />
(B)
<u> | A a </u>
<u>A | AA Aa </u>
<u>a | aA aa </u>
<u />
(C)
<u> | A A </u>
<u>A | AA AA </u>
<u>A | AA AA </u>
<u />
(D)
<u> | A a </u>
<u>a | aA aa </u>
<u>a | aA aa </u>
<u />
