keratin is a protein expressed in skin but not in white blood cells. how many alleles for keratin are in gametes?
In gametes, there are either one (if the person is homozygous) or two keratin genes (if the individual is heterozygous).
The number of alleles for keratin in gametes depends on the genetic makeup of the individual. Keratin is a protein that is expressed in skin cells but not in white blood cells. It is encoded by a gene that is present in the genome of an individual, and each person inherits two copies of this gene (one from each parent).
These two copies, or alleles, may be identical or different, and they determine the individual's genetic information for keratin. If both alleles are the same, the individual is homozygous for that gene. If the alleles are different, the individual is heterozygous.
During meiosis, the process by which gametes are formed, the two alleles for each gene segregate, meaning that each gamete receives only one of the two alleles.
Therefore, the number of alleles for keratin in gametes is either one (if the individual is homozygous) or two (if the individual is heterozygous).

why is a chloroplast kept in darkness for some time prior to being fixed for electron micrscopy does not contain starch
The reason for keeping a chloroplast in darkness for some time prior to fixation for electron microscopy is to deplete the starch content within the chloroplast.
Starch is a storage carbohydrate that accumulates in chloroplasts during the light period through photosynthesis.
By keeping the chloroplast in darkness, the plant is not actively performing photosynthesis, and therefore, the starch reserves are gradually depleted.
When preparing samples for electron microscopy, it is important to fix the chloroplasts.
If the chloroplast contains starch, it can be affected during the fixation process, leading to distortions in the final electron micrographs.
Thus, by depleting starch the chloroplast is closer to its natural state, allowing for more accurate observations and analysis under the electron microscope.

Ca++ ions that were stored in the sarcoplasmic reticulum are then released as a result of this (SR).Action potentials are transported into the interior of muscle fibers by the T-tubules, where they activate voltage-gated channels known as dihydropyridine receptors (DHPR). The amount of calcium that enters the muscle fiber from the extracellular space is much lower than it is in cardiac muscle (via the DHPR).The ryanodine receptors (RyRs) in the SR open and release calcium, which stimulates contraction. These events are triggered by the action potential, which invades T-tubules and opens L-type calcium channels.For more information on action potential kindly visit to
