Taxol is a drug that comes from the bark of a tree that binds and irreversibly stabilizes microtubules. It is often used during chemotherapy to kill dividing cancer cells. How does taxol block cell division?
A-
Taxol prevents the contractile ring from forming and dividing the cell in two.
B-
Taxol prevents DNA replication.
C-
Taxol prevents chromosome condensation during prophase.
D-
Taxol prevents spindle formation and separation of chromatids.
Answer: D-
Taxol prevents spindle formation and separation of chromatids.
Explanation:
The Taxol is used as an anticancer drug formulation. It is obtained from yew tree. An anticancer drug affects the cell cycle machinery so as to limit the production of cancer cells. This drug ceases the microtube formation in animal cells. This prevents the spindle fiber formation and further prevents the mitosis of cancerous cancers as the chromosomes will not separate apart and so abnormal cells will not produce further.
Answer:
Types of tissues:-
Nervous tissue, Epithelial tissue, Muscle tissue, and Connective tissue.
Explanation:
Nervous tissue is made up of nerve cells (neurons) and is used to carry "messages" to and from various parts of the body.
Examples are cells, neurons and glial cells.
Muscle tissue includes striated (also called voluntary) muscles that move the skeleton, and smooth muscle, such as the muscles that surround the stomach.
Examples are blood vessels, biceps and intestines.
Epithelial tissue provides a covering (skin, the linings of the various passages inside the body).
An example is the epidermis, the outermost layer of the skin and outerlayers on internal organs.
Connective tissue supports other tissues and binds them together (bone, blood, and lymph tissues).
Examples include adipose, cartilage, bone, blood, and lymph.

Explanation:
DDT is an insecticide that can pass up the food chain from insects to small birds, and then from the small birds to birds of prey, like hawks. It can accumulate in the birds of prey, giving them a large amount of DDT
