Chemotherapy targets fast growing cells , including cancer cells ,skin cells, Gastro intestinal cells, blood cells etc.
Explanation:
- Chemotherapy refers to use of chemicals to treat diseases like, cancer.
- This procedure involves the use of cytotoxic chemicals that inhibit mitosis.
- Drugs used in Chemotherapy principally target fast growing cells of the body .
- Thus along with cancer cells these drugs also effect normal body cells such as , blood cells, skin cells etc.
- Damage to blood cells weakens the immune system and the patient is susceptible to other diseases also.
- To avoid such situation chemotherapy is accompanied with other combination medicines.
- Even after having several side effects chemotherapy is suggested as most suitable treatment to reduce symptoms of most type of cancer because it involves the introduction of drugs into the blood and thus can be targeted to any anatomical location in the body.
Answer:
survive in their environment
Explanation:
According to Darwin's theory of evolution, natural selection is the main mechanism. Darwin explains that organisms that have heritable traits that help them survive and reproduce, will be favorable by natural selection. Those favorable traits will enable organism to better adapt to their environment and to pass more genes on to the next generation (offspring).
Organisms adapt to their environment by changing their behavior, structural traits or physiology as a response to environmental change, so that they become well suited to it.
A dihybrid cross means that both parents are heterozygous (which is both expressing the dominant form) for two genes.
Resistance stage of the general
adaptation syndrome (gas)
Resistance stage is the second
stage in which the body goes through series of changes while trying to resist
or adapt to the stressor. For the question given above, according to Hans Selye,
Katie is currently in the resistance stage of the general adaptation syndrome
(gas).
The Serratus anterior in man is homologous to the Serratus ventralis muscle in the cat. The Serratus anterior is a muscle that originates on the surface of the 1st to 8th ribs at the side of the chest and insects along the entire anterior length of the medial border of the scapula. The Serratus anterior acts to pull the scapula forward around the thorax. Serratus ventralis in the cats looks like fingers because it attaches to the ribs, but has nothing to attach to between the ribs.
