In the experiment, the independent variable is the drug amount. Experiment group is given certain amount of drug, control group is not given the drug. The dependent variable is the body fat. I think you means the control is the living environment including food and water.
The male
human has a sperm cell and the female has an egg cell. The cells from the male
and female that combine to form a zygote are called gametes. The human sperm
and egg cells each contain 23 chromosomes. . A combination of gametes forms a
zygote with 46 chromosomes. The type of cell division that produces gametes
with half the normal chromosome number is the meiosis. Meiosis is the type of
cell division used in sexual reproduction. It will occur in the testes and
ovaries.<span>Chromosomes get
shuffled when eggs and sperm are made. Though most adult cells contain two sets
of chromosomes, sperm and egg cells are different. These special cells have
just one chromosome from each pair. Which chromosome they get from each pair is
random, making each sperm or egg cell unique. There is also a bit of mixing
before the chromosomes are sorted into individual sperm or egg cells.
Chromosomes from each pair in a mother or father, respectively, make contact
and exchange pieces of DNA, creating hybrid chromosomes. </span>
The answer to the question is enzyme linked receptor.
I would say D because it involves more selection but if that one is wrong it is most likely B. But I would go with D
The 3 and 4 are the structures at which the tympanic membrane to the oval window are communicated.
<h3>An example of a tympanic test</h3>
How well your middle ear is functioning is determined through a test called tympanometry. By tracking the motion of your eardrum, it does this. The outer ear, middle ear, and inner ear are all separate structures that make up your ear. You receive sound as energy or vibrations through your outer ear.
<h3>The tympanic bone's location is unknown.</h3>
The temporal bone's tympanic portion, which surrounds the external portion of the ear canal, is a curving plate of bone that sits under the squamous portion, in front of the mastoid process.
