<span>Steroids are lipids because they are hydrophobic and insoluble in water, but they do not resemble lipids since they have a structure composed of four fused rings. Cholesterol is the most common steroid and is the precursor to vitamin D, testosterone, estrogen, progesterone, aldosterone, cortisol, and bile salts.</span>
The development of zygote into a blastula is called cleavage.
Cleavage is a division oflr separation of form. The act or state of splitting or dividing of a cell, particularly during the telophase
Hope this helped :)
Have a great day
Nucleotides can be radiolabeled before they are incorporated into newly forming DNA and, therefore, can be assayed to track their incorporation. In a set of experiments, a student-faculty research team used labeled T nucleotides to study the incorporation of labeled nucleotides into a culture of lymphocytes. They found that the lymphocytes incorporated the labeled nucleotide at a significantly higher level after a pathogen was introduced into the culture. they might conclude from this observation is that the Infection causes lymphocytes to divide more rapidly
- Lymphocytes is a type of immune cell produced in the bone marrow and present in the blood and lymphatic tissue. B lymphocytes and T lymphocytes are the two main types of lymphocytes. T lymphocytes help eliminate tumour cells and govern immune responses, whereas B lymphocytes produce antibodies. A lymphocyte is a white blood cell type.

<h3>Then the net population growth is zero.</h3>
Explanation:
When the birth rate is equal to each woman producing exactly enough offspring to replace herself and her offspring's father, and the birth rate is sustained for a generation, then there will be no increase in population so the net population growth will be zero.
Population of species is defined as the number of individuals of a given species.
For example, if their were 50 individuals in a population and a woman out of them mates with a man and produces one offspring to replace her and one offspring to replace her offspring's father, and then both of them die.
So the intrinsic rate of population growth = No. of birth -no. of death
