Increased carbon in the oceans has caused the pH levels of the water to decrease. What is the largest impact of this ocean acidification on marine life?Increased coral bleaching
Increased fish predation
Increased marine bird migration distances
Increased marine mammal hibernation time

Answers

Answer 1
Answer:

Answer:

Option (1)

Explanation:

The amount of carbon present in the ocean is inversely proportional to the pH level of water. This CO₂ amount present in the atmosphere may rise because of various types of human activities, that results in the increasing amount of dissolved CO₂ in the oceans. This in turn, again decreases the pH level of water. This water when reduces, it becomes saturated with the CO₂ and it also diminishes the source of calcium carbonate.  

The increase in the ocean acidification leads to the significant reduction of the reef-building corals. As a result of which the temperature of the water increases and they are not able to assemble their skeletal parts.

Hence, the correct answer is option (1).
Answer 2
Answer: Increased coral bleaching

Which organic molecule is responsible for the insulation of internal organs against shock?

Answers

Answer:

The correct answer would be B. lipids.

Explanation:

Lipids are the compounds that are fatty acids or derivatives of the fatty acid that are insoluble in water and soluble in nonpolar solvents such as ether. These are some of the essential molecules of the bodies. these molecules have various functions in the body.

Such energy storage in the adipose tissues and utilize when there is not enough level of glucose, insulation: subcutaneous fats help in insulation as act as a blanket layer and insulate the body from external temperatures. Protection is also an essential function of lipids that protect the internal organs from shocks.

Thus, the correct answer is option B. lipids.
Which organic molecule is responsible for the insulation of internal organs against shock?Carbohydrates

A plant breeder found a species of flowering plant with very attractive flowers growing wild in a field and she thought it would appeal to her customers. Some of the plants of this species had red flowers, some white flowers, and some pink flowers. While she would like to be able to offer her customers all three colors of flowers, she only has permission from the landowner to dig up one plant to bring back to the nursery as breeding stock. What would be the best thing for her to do?A. Take a white flowering plants is the white allele could be masking the pink allele
B. Tickle pink flowering plant since it is likely to carry both the red and white Alleles
C. Take a red flowering plants if they could produce all three colors eventually
D. Take a red flowering plants is the red Allele Is likely the dominant one
