Answer:

CLOSED.

Explanation:

Stomata are found in epidermal layers in green aerial parts of plants, especially leaves. They occur mainly on the lower surface of dicotyledonous leaves, although on monocotyledonous, they are found on both surfaces. Intercellular air spaces found throughout the leaf are linked to stomata.

Stomata permits plant uptake of carbon dioxide, which is a necessity for photosynthetic processes. They also help to reduce water loss by closing when conditions are hot or dry. Stomata look like tiny mouths which open and close as they assist in transpiration.

Therefore, it can be said that Stomata adjust temperature, staying closed when temperatures are hot and dry.

icang [17]

Answer:

This question is incomplete

Explanation:

This question is incomplete because of the absence of the chart referred to in the question. However, what appears to be the case is that the three nitrogenous bases represent codons (and the missing chart is the codon chart). The mutation that has the potential to cause more damage will be the one that would change the amino acid formed from the codon change.

A. CAU to CAC: The codons CAU and CAC both form the amino acid histidine and thus is not expected to cause a major damage.

B. UGU to UGC: The codons UGU and UGC both form the amino acid cysteine and thus is not expected to cause a major damage.

C. UCU to UUU: <u>Codon UCU forms the amino acid serine while the codon UUU forms the amino acid phenylalanine</u>. Thus, this eventual change in the amino acid formed has the potential to cause a major damage and thus option C is the correct option.

NOTE that a codon is a sequence of three DNA/RNA nucleotides that corresponds to a single amino acid.
