Answer:
A major factor in determining the mode of nitrogen excretion is the availability of water in the environment. Generally, aquatic animals excrete mostly ammonia, whereas terrestrial animals excrete either urea or uric acid.
Explanation:
The answer is A. Mitosis results in daughter cells through one division cycle while meiosis results in haploid gametes through two division cycles.
Answer:
I think that Viruses are not alive so Being composed of molecules that are found in cells (nucleic acids, proteins, lipids and complex sugars) and having the capacity to evolve, viruses are often said to be alive. But they aren't alive because they arent a living thing.
Answer:
The question is incomplete, it lacks options. The options are:
A) It has made the demand for insulin decrease.
B) It has made the incidence of diabetes decrease.
C) It has made it easier for diabetics to inject themselves with insulin.
D) It has made insulin cheaper and more readily available.
The answer is D
Explanation:
Genetic engineering is a biotechnological procedure that involves the transfer of genes from one organism to another using biotechnology. In this case, bacteria cells are said to be genetically modified because their genetic content is tampered with and the genes that produces the insulin protein in humans is added into their genome. Hence, they transcribe and translate this gene to produce the protein-insulin.
Diabetic patients cannot produce this insulin in their system. Hence, the insulin produced from this genetically modified bacteria cells can be administered to diabetics via injection. This genetically modified way of producing insulin has proven to be a far better option to the previous practice of slaughtering cattles and pigs to obtain this protein because the GM method allows insulin to be produced in large amounts making it available and cheaper to diabetics.

Homeostasis- state of maintaining a stable internal enviornment despite changing external conditions
