Answer:
Option C.
Ocean acidification is the main ecological problem due to mariculture.
Explanation:
- Mariculture also known as the aquaculture that stands for the fish farming occupation.
- The main ecological problem that mariclture addresses is the environmental degradation especially the water pollution.
- Many studies suggests that the tradition of mariculture has been increasing the acidificaton in ocean water that is directly affecting the marine organisms and plants.
- A build up of organic material beneath fish farms impacts the flora and fauna of an area.
- That makes drastic changes on sediment chemistry.

Hey You!
I believe this is true, as chemotherapy is most effective at killing cells that are rapidly dividing.
Answer:
1. <u>ntrdr</u> --><u> brken</u> --| <u>wag1</u> --> <u>Tail structures
</u>
2. Yes
Explanation:
(1) In this experiment three different genes are present;
1) Wag-1 - promotes production of tail structures
2) brkn gene - inhibits Wag-1 which leads to inhibition or inactive Wag1 gene and there is no tail formation.
3) ntrdr gene - stimulates the activity of brkn gene thus this in turn inhibits Wag-1 gene and results in inhibiting the tail formation.
(2) The ntrdr gene stimulates the brkn gene and active brkn gene inhibits the wag-1 gene. As we know Wag1 gene is essential for tail formation. on removing out ntrdr gene result in inactive gene brkn thus allows the expression of the Wag-1 gene allowing tail growth in dogs.
Answer: Option A.
During Mitosis in S phase DNA is replicated.
Explanation:
S phase(synthesis phase) Is the second phase in interphase. It is during this phase that DNA is replicated or synthesized through mitosis in interphase. This phase allow DNA to be doubled before it enter the cell, the doubled DNA is divided into daughter cells.
