The answer is Parathyroid Hormone (PTH). Steroids reduce calcium
levels in the blood. This results in activation of the parathyroid hormone that
is essential in the metabolism of calcium
in the blood. PTH induces reabsorption of
calcium from bones to restore homeostasis
Ca2+ levels in the blood hence causing
osteoporosis. Osteoporosis causes an increased risk of bone fractures.
The answer is proofreading feature of DNA polymerase. As the DNA polymerase III replicates DNA, it
has a proofreading mechanism in one of the
subunits of the holoenzyme. This subunit detects a bad conformation in the double
helix when the wrong base pair is placed.
In this case, the DNA polymerase III backs up
a bit and waits for the exonuclease to nick out the misplaced base.
1. Nucleic acids are the molecules that code the genetic information of organisms.
2. The two nucleic acids used in the repair, reproduction and protein synthesis are deoxyribonucleic acid (DNA, shown) and ribonucleic acid (RNA)
3. DNA and RNA are polymers made up of monomers called nucleotides
Answer:
The genotype of parents for 6 exceptional cross was
Bb * bb
Result for crossing the black and white guinea pigs from the 6 exceptional cases.
Bb * bb
Bb, Bb, bb, bb
Explanation:
Here trait for black guinea is dominant over the trait for white guinea
There is a possibility that for remaining 6 crosses, the genotype of parents would be as follows
Black guinea pig - Bb
White guinea pig - bb
Now when these two genotypes are crossed the following offsprings are produced
Bb * bb
Bb, Bb, bb, bb
Thus, out of four offspring half of them are heterozygous black and remaining half of them are white in color.
Now if these black and white guinea pigs from the 6 exceptional cases with genotype Bb and bb are crossed respectively, then following offspring are produced
Bb * bb
Bb, Bb, bb, bb
Your body cells use oxygen you breath to get energy from the foods you eat. The process is called "Cellular Respiration." This process or function consists of the cell using oxygen to break down sugars in the body. When the cell uses the oxygen to break down sugars, carbon-dioxide is produced and energy is released, thus producing the energy your body needs.
"Hemoglobin" is a protein with Red Blood cells (also referred to as RBC's) that are responsible for the transport of oxygen. The Cardiovascular System consists of the heart and vessels and may also be referred to as the vascular system or the circulatory system. The heart functions as a muscular pump that pushes blood through the vessels to all areas of the body and the vessels function to carry it back to the heart as well. Hence the name "circulatory."
