Why do you think leaves have stomata on their underside only? Explain.

Answers

Answer 1
The stomata must be open during the daylight hours to let oxygen and carbon dioxide pass through. While they are open, water vapor escapes into the atmosphere (transpiration). ... Transpiration is the loss of water through stomata, so, more stomata are found on the lower surface to prevent excessive loss of water.

In a lotus plant, stomata is found on the upper epidermis of the leaf.

Stomata are responsible for the exchange of gas with the surrounding atmosphere of the leaf. Their guard cells stay taut during the day to keep the stoma open.

Guard cells can only stay open if they are saturated with a certain quantity of water.

From this information we can infer that stomata are typically found on the lower epidermis to prevent water damage when it rains.

The rain would not only cover the openings, it would also ruin the osmotic balance of the guard cells causing inefficiency and damage to the cycle of gaseous exchange.

Natural selection probably selected against such plants giving rise to those with stomata on the underside.

To melt the ice during the winter season, road crews often put sand and salt solutions on the roadways to help melt the snow and ice. The plants that live close to the road often die or wilt after this procedure. Using your knowledge of osmosis and plant structures, which type of solution would cause this to happen to plant cells? Group of answer choices

Answers

Answer:

The missing answer choices are:

a. hypotonic

b. isotonic

c. osmosis

d. hypertonic

The correct option is d. hypertonic

Explanation:

A hypertonic solution has a higher concentration of solutes than the concentration of solutes present inside the plant. As there is a difference in concentration between the inside and the outside of the plant, the plant loses water in an attempt to balance the difference. As a result, there is an excessive loss of water that dehydrates the plant and kills it.

Answers

Answer:

Due to environmental conditions.

Explanation:

With the passage of time, environmental conditions change which causes the evolution of of four legged land animals from fish like creature. This change occurs due to change in environment. In water, there is no need for legs because fish moves with the help of fins and tail but the organisms that lives on land has legs in order to move from one place to another so we can say that change in the physical structure of organism occurs due to environment.

Which statement explains why the structure of sickle cells differs from normal red blood cells?
a. The gene mutation affected protein synthesis.
b. The gene mutation prohibited DNA replication.
c. The gene mutation inhibited the cell's ability to produce tRNA.
d. The gene mutation affected the cell's ability to produce ATP.​

Answers

Answer:

A. the gene mutation affected protein synthesis

Explanation:

Basically, sickle cell results due to point mutation (change in one nucleotide) in DNA, which in turns affects the mRNA produced and finally the protein made from that mRNA is affected. I have listed a helpful image below which shows that the mutation actually results in formation of an undesired protein which causes sickle cell to occur.
