Explanation:
Having filtered out small essential molecules from the blood - the kidneys must reabsorb the molecules which are needed, while allowing those molecules which are not needed to pass out in the urine. Therefore, the kidneys selectively reabsorb only those molecules which the body needs back in the bloodstream.
Answer:
Answer is 2. Fibroblasts fail to divide.
Explanation:
Tissue culture experiment is the experiment where tissues are grown in an artificial medium. This involves the use of growth medium such as agar or broth. This process help to produce needed tissues in a short period of time.
Fibroblasts are cells which are found in the collective tissues, and they produce collagen. The collagen produced by the Fibroblasts play important role in tissue repair. Fibroblasts are regarded as the main cells in the connective tissue.
Note that, PDGF, which is Platelet -derived growth factor in full, is a growth factor regulating cell growth and it's division.
Hemophilia is considered a sex-linked recessive disorder which means the disease does not occur if only one gene in a pair is abnormal.
Inheritance pattern of the offspring of a father who has hemophilia and a mother who does not have hemophilia and is not a carrier:
- all sons will be born normal
- all daughters will be carriers
Inheritance pattern of the offspring of a father who has hemophilia and a mother who is a carrier:
- 25% chance of having a hemophiliac son
- 25% chance of having a son with no hemophilia
- 25% chance of having a daughter who is a carrier
- 25% chance of having a hemophiliac daughter
Answer:
Explanation:
Codominance means that neither allele can mask the expression of the other allele. An example in humans would be the ABO blood group, where alleles A and alleles B are both expressed. So if an individual inherits allele A from their mother and allele B from their father, they have blood type AB.
