Answer:
B. In plants, there are no sister chromatids.
<h2>Incomplete dominance & Co dominance</h2>
Explanation:
- Twist- The mutant allele is prevailing to its relating wild-type allele.
- forked-the mutant allele is predominant to its relating wild-type allele.
- Pale-The mutant allele is neither prevailing nor totally passive to its comparing wild-type allele.
- Mendel's outcomes were earth shattering halfway in light of the fact that they repudiated the (at that point well known) thought that guardians' attributes were for all time mixed in their posterity. At times, the phenotype of a heterozygous living being can really be a mix between the phenotypes of its homozygous guardians.
- Closely identified with inadequate predominance is codominance, in which the two alleles are all the while communicated in the heterozygote.
- Hence, the twist mutations are codominant allels at same locus.
positive feedback could be contractions(as painful as it may seem, its true) in child birth and the ripening of fruit.
negative feedback include the regulation of blood glucose levels and osmoregulation
Answer:
The correct answer will be-ventral ramus
Explanation:
Rectus abdominis is a skeletal muscle found in the front part of the body which begins from the sternum and ends at the pubic zone.
Rectus abdominis is also known as "Abs" which viewed externally appears to be six, eight or ten in number.
These muscles are innervated by the thoracoabdominal nerves which carry and transmit signals to CNS and to the muscles back. The main spinal nerve which controls the movement of Abs is known as the "ventral ramus".
Thus, ventral ramus is the correct answer.
Cancer cells are the cells that divide rapidly than any other cells in the body. The drugs used in chemotherapy work on rapidly dividing cancer cells. Some cells of our body apart from cancer cells also divide rapidly along with the cancer cells such as the cells that line the stomach and the digestive tract. Chemotherapy drugs cannot differentiate the cancer cells and the normal cells so these drugs also attack the normal cells which divide rapidly along with the cancer cells. The drugs also attack the cells that are present in the roots of the hair. So, this results in the hair loss. Hair loss does not occur immediately after the chemotherapy treatment instead it starts after few treatments. The degree of the hair loss after chemotherapy depends on the drug type and process. So when the chemotherapy drugs are used it results in the hair loss and nausea.
Therefore, when chemotherapy drugs attack normal cells including the roots of the hair instead of cancer cells that divide rapidly along with the cancer cells it results in the hair loss and nausea.
