Answer:
There is no change, the lac l gene is constitutively expressed, regardless of the presence of lactose.
Explanation:
Lacl gene codes for the lac repressor hence is always expressed to produce lac repressors which may or may not be bounded dependent on the presence of lactose. Lacl gene expression is not regulated, thus is constitutively expressed.
Because the earth's is roughly spherical the sun's light is distributed over a wider area towards the poles, so it has less heating effect... the air cools and falls over the poles and returns to the equator close to the ground. This assumes that there is no other effect (e.g. wind, low or high pressure regions etc.)
Answer:
Ovary
Explanation:
Anthophyta or the angiosperm are the plants which bear reproductive structure in a colorful modified shoot called flower.
The flower contains both male and female reproductive structures. It is the female reproductive structure that develops into the fruits when the female egg cell is fertilized with the sperm.
The female reproductive structure is made of the style, stigma and the ovary. The ovary encloses the egg cell which after fertilization becomes an embryo and the ovule turns into the seed and the ovary turns into the fruits. That is why the fruits bear the seeds.
Thus, the ovary is correct.
