Answers
Answer:
1 ) Living organisms can be divided into different taxa based on their characteristics. The name given to this process of classification is taxonomy.
2) Compound epithelium provide protection
against chemical and mechanical stresses.
3) Pine tree
4) is due to the presence of mineral salt in the osteoid matrix, which is a crystalline complex of calcium and phosphate.
5)When stamens are seen as arising from the perianth lobe (tepals), they are called epiphyllous.Epiphyllous stamens can be seen in tube-rose.
6)Nervous tissue is found in the brain, spinal cord, and nerves. It is responsible for coordinating and controlling many body activities.
7)Mitosis is a way of making more cells that are genetically the same as the parent cell. It plays an important part in the development of embryos, and it is important for the growth and development of our bodies as well. Mitosis produces new cells, and replaces cells that are old, lost or damaged.
8)Citric acid.
9) a.insulin
b.thyroxine
c.thyroid hormone.
Terrestrial animals are generally either ureotelic or uricotelic, not ammonotelic because, terrestial animals need to conserve water. Since, ammonia is toxic in nature and water soluble and can not be totaly eleminated from body.
