Binary fission enables them to reproduce quickly.
Answer:
Cells are so little, so they can maximize their ratio of surface area to volume.
Explanation:
Smaller cells have a higher ratio which allows more molecules and ions to move across the cell membrane per unit of cytoplasmic volume. Cells are so small because they need to be able to get the nutrients in and the waste out quickly.
Answer: Adaptive immunity
Explanation:
The adaptive immunity is also known as acquired immunity. It is a sub system of the overall immunity.
It can defined as the immunity which is not present in the body when we are born. It develops in the body when it is exposed to the pathogens no matter it is natural or artificial.
The acquired immunity can develop in the body and makes the body susceptible to infections and develops prevention for the next time when the body will be exposed for the next time.
Fertilization generally occurs in the fallopian tube.
Answer:
Thyroid hormones
Explanation:
Animals and people exposed to pesticides such as insecticides, fungicides, and herbicides, have shown to be affected by their effect on the thyroid. These chemicals can produce endocrine alterations acting as thyroid disrupters. They affect many mechanisms in the organisms such as inhibition of thyroid iodine uptake, <u><em>interference with the thyroid hormone receptor</em></u>, binding to transport proteins, among others. They cause toxicity in the functioning of the hypothalamic-pituitary-thyroid axis.
There are many studies that associate thyroid diseases with exposure to organochloride pesticides. Significant alteration in the TSH, T3, and T4 levels have been expressed by people directly or indirectly exposed to the chemicals.
