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.
Biodiversity conservation protects plant, animal, microbial and genetic resources for food production, agriculture, and ecosystem functions such as fertilizing the soil, recycling nutrients, regulating pests and disease, controlling erosion, and pollinating crops and trees.
Meiosis is needed for sexual reproduction, here chromosome number is halved, it provides for mixing up of genes.
mitosis is needed for growth, repair, replacement, asexual reproduction.
it maintains same chromosome number
<h3><u>Comparison between Galapagos penguin and cold adapted Emperor penguin of Antarctica:</u></h3>
<u>Galapagos penguin:</u>
- Galapagos penguins are the only species of penguins that live north of the Equator.
- The Galapagos penguins breed all-round the year.
- The Galapagos penguins are smaller compared to the cold-adapted emperor penguins of Antarctica.
- The breeding and nesting place of the Galapagos penguins lie on the shoreline.
<u>Emperor penguin:</u>
- The emperor penguins live and adapt to the cold Antarctic environment.
- The Emperor penguins breed only during the Antarctic winters.
- The nesting of emperor penguins is on ice cliffs and icebergs where the eggs are protected from the strong and cold Antarctic winds.
- However, both of these species of penguins are at risk of extinction due to the rise in temperature and shortage of foods.
