The correct option is C

C.Stomata would not open and close.

This is because guard cells play an important function of controlling stomata. the ensures that stomata are open during the day and closed during the night for the purposes of photosynthesis. The stomata are the pores that are found on the under surface of a plant leave,whose role is gaseous exchange.

Answer: C. Stomata would not open and close.

Explanation: The main function of guard cells is to regulate the opening and closing of the pore formed between the gap of two guard cells, termed as stomata. Option A is incorrect as stomata are the least susceptible area from where pathogens can enter the plant cell. Option B is incorrect because photosynthesis is not directly and much affected by guard cells. Option D is incorrect as chloroplasts are not associated with the guard cells. Stomata are directly linked with movement of guard cells, so correct answer is option C. Through stomata, exchange of gases and water vapor takes place.

Describe how the role of phloem would would be affected if the leaves start to die off

Naya [18.7K]

The conductive tissues of the angiosperms are the xylem which drives the raw sap and the phloem which conducts the elaborate sap.The phloem, or liber, drives the elaborate sap, solution of organic substances rich in carbohydrates, from the leaves to the other organs.

The elaborate sap (which contains organic substances produces by photosynthesis) is produced in the leaves, where the majority of the chlorophyll subsist, so if the leave die off, the production of organic substances and the elaborate sap are reduced, so its transport by the phloem will be reduced, and this is how the phloem will be affected by the dying of the leaves.

What kind of mutation would occur if a sequence of DNA is changed from ATCGGCTTAACG to ATCGGCTAAACG?

Zinaida [17]

Answer:

Base substitution mutation

Explanation:

Mutation is the alteration or change that occurs to the sequence of a gene caused by a mutagen (chemicals) or spontaneously-induced. Depending on how the mutation occurs, it is of different types. The mutation shown in this question is as follows:

ATCGGCTTAACG to ATCGGCTAAACG

This type of mutation is called SUBSTITUTION MUTATION. Substitution mutation is a type of mutation that involves the replacement of one or more nucleotide base by another. In this original sequence; ATCGGCTTAACG, the eight base T was replaced by base A in the sequence, hence, it is a substitution mutation.

Metabolic acids __________. are acid participants in, or by-products of, cellular metabolism can leave the body by entering the

Marianna [84]

Answer:

a. are acid participants in, or by-products of, cellular metabolism

Explanation:

cellular metabolism is the process in which several chemical recation stakes place in body. there aretwo type of cellular metabolism - catabolism and anabolsim, which serves for several body functions.

During the chemical reaction of cellular metabolism, many acids are produced which are called metabolic acids. Several metabolic pathways produces different acids such as carboxylic acid, citric acid and amino acid. All the metabolic acid maintains body's functional activities,if any case acid formation increases it causes metabloic acidosis.

Hence, the correct option is a. "Metabolic acids are the acid participants of celular metablosim".
