46 chromosomes. 23 pairs. 23 chromosomes come from the egg (from the mother) and 23 come from the sperm (from the father). Haploid (containing one set of chromosomes) sperm and egg fuse to form a diploid (containing two sets of chromosomes, one from each parent) zygote.
<span>This is most likely caused by horizontal gene transfer, which is the process of transmission of genetic material between organisms caused by any process different than parent to offspring transmission (which would be vertical transmission). This has heavily influenced evolution</span>
I would go with false, because not only 100,000 genes, there are lots to those. and there are not even like 100,000 genes, that is not really possible!!
hope that this helps you! =)
The right answer is both of them.
Take the example of fatty acids, it is an aliphatic chain carboxylic acid composed of 4 to 36 carbon molecules. The more carbons (and therefore the CC and CH bonds), the more the fatty acid will be rich in energy since it will give more ATP during its catabolism, and it will also be less and less soluble in water because the carbon chain is hydrphobic.
Answer:
The correct answer would be Atria push blood into the ventricles and Ventricles push blood out of the heart.
In humans, four chambered heart is present with two atria and two ventricles.
Deoxygenated blood from all over the body is passed into the right atrium through vena cava (superior and inferior).
Simultaneously, oxygenated blood from the lungs is passed into the left atrium of the heart with the help of pulmonary vein.
Both the atria contract at the same time to drain their blood into respective ventricles.
The ventricles undergo relaxation while receiving blood.
The valves present between the atria and ventricles (tricuspid and bicuspid valve) ensures that the blood flows in one way direction only. They shut down as the ventricles contract and produce the sound "lub".
The ventricles contract simultaneously to pump blood out of the heart. The right ventricle pumps deoxygenated blood into pulmonary artery which takes the blood to the lungs for oxygenation.
The left ventricle passes the oxygenated blood through aorta to all the parts of the body.
The pulmonary and aortic valves prevent the back flow of blood and shut at the same time which creates second sound called as "dub".
