Answer:
B) The first and second answers are correct.
Explanation:
The law of Independent assortment is one of the four laws of Mendel which states that alleles located on the chromosomes segregate or assort independently of each other.
This means that whether they are present close to each other or they are present at a distance they can be passed on in the generation together but they will show their effect on the phenotype independent of each other.
The law was concluded form the result of the dihybrid cross which showed that although the two genes were controlling the trait each allele will show its effect independent of each other or like a monohybrid result.
Thus, Option-B is the correct answer.
Answer:
What occurs when too much of a population rely on something?
This leads to overcrowding after which competition sets in and it would diminish the resources and death of the unfit organism while the fittest survives.

Answer:
To maintain body homeostasis
Explanation:
The endocrine system consists of the endocrine glands that release hormones directly int the blood. Those hormones bind to their receptors on the target cells and thus regulate their function. The major glands are:
pineal gland-releases melatonin, controls sleep cycle
pituitary gland-control growth, blood pressure, thyroid glands and metabolism etc.
pancreas-secretes insulin and glucagon, control of blood sugar levels
ovaries, testes-reproductive role (release female and male hormones)
thyroid gland-controls metabolism and protein synthesis
parathyroid gland-controls Ca levels
hypothalamus-connects nervous and endocrine systems, controls other glands
adrenal glands-release adrenalin and steroid hormones.
