1. Plants, unlike animals, cannot move. <span>Living things move primarily to replenish their energy and find security by hiding from predators. Plants are able to do both quite fine while stationary as they are capable of mobilizing their inherent resources, plus those available from soil with the help of sunlight to make food</span> 2. Desert plants have needles instead of leaves to help prevent water loss and discourage animals from eating the plants. Desert plants tend to look very different from plants native to other regions. They are often swollen, spiny, and have tiny leaves that are rarely bright green. Their remarkable adaptations to the challenges of the desert climate. 3. As mentioned in the video; horseradish is spicy because the radish plants stores toxins in its roots for protection. The pungency of horseradish is essentially a defense mechanism against herbivores. Plants do not have legs, therefore, they have evolved to protect themselves; for example the defensive poison by horseradish gives it's hallmark pungency.
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:
C. active transport driven directly or indirectly by metabolic energy
Explanation:
The intestinal mucosa is the tissue that lines the inner walls of the intestines. It is characterized by the pleated appearance, which facilitates the absorption of nutrients already deferred and the formation of fecal cake. Most nutrients are absorbed by this region through active transport directly or indirectly driven by metabolic energy.
B An ecosystem because it is i dont know how to explain but i think is that one
