A patient who
underwent mastectomy with removal of lymph node mostly experience swelling of arm on the affected side. The nurse should
instruct the patient to elevate the arm above the heart, perform isometric
exercise where <span>the muscle fibers are activated even though there is no
movement and massage is important to allow blood circulation and lessen the
edema of the arm.</span>
Answer:
Oxygen is the component of Earth's atmosphere which exists entirely as a result of photosynthesis.
<span>Excess nitrogen is brought in the pond from the fertilizer, which are ladden in nitrogen and phosphorous, and rain water or running water takes that nitrogen to the water bodies.Bacteria must have come from the sewage disposal in the pond. Sewage is rich in organic material and allows proliferation of bacteria, which is taken to the pond when the sewage is disposed in the pond.</span><span />
Answer:
The wings of the wasp have high in length due to the presence of dominant gene.
Explanation:
There are two genes present in wasp which indicates the length of the wing. The recessive gene represents short wing while dominant gene represent high length. So the offspring which is produced from the mating of male and female wasp produces offspring having high length of wings. It is because in the offspring only dominant gene expressed while the recessive gene remain hidden.
Answer:
Translocation
Explanation:
Translocation is a chromosomal abnormality (mutation) in which a chromosome breaks and a portion of it reattaches to a different chromosomal location. It can occur during the formation of sperms and eggs during meiosis.
Translocation is of two main types: 1. Reciprocal location, in which two fragments break off from two different (non-homologous) chromosomes and switch places.
2. Robertsonian translocation, in which an entire chromosome (usually acrocentric) becomes attached to another chromosome (acrocentric) at the centromere to form a metacentric chromosome.
Translocation can either be BALANCED, where no genetic information is missing or additional. Hence, there is an even exchange with no adverse effect on the affected individual or UNBALANCED, where the exchange of chromosomal material is unequal resulting in an extra or missing genes.
