CAM plants keep stomata closed in the daytime, thus reducing loss of water. They can do this because they - fix CO{2} into organic acids during the night.

The correct option is a.

As an adaptation to dry environments, certain plants developed a carbon fixation mechanism known as crassulacean acid metabolism, or CAM photosynthesis, which enables a plant to photosynthesize during the day but only exchange gases at night.

During the day, the malate is transferred to chloroplasts where it is transformed back to CO2, which is then utilised during photosynthesis. At night, the CO2 is stored as the four-carbon acid malic acid in vacuoles. The enzyme RuBisCO is surrounded by a concentration of pre-collected CO2, which improves photosynthetic efficiency. Plants in the Crassulaceae family were the ones that initially revealed this process of acid metabolism.

Suppose a plant breeder wants to isolate mutants in tomatoes that are defective in DNA repair. However, this breeder does not ha
Nana76 [90]

The provided question has marked options incorrectely the correct order as follows:

A) Expose putative DNA repair mutant plants to ionizing radiation L and see if they survive less well than wild-type plants.

B) Measure the amount of post-translational processing that occurs in the putative DNA repair mutant plants.

C) Measure the somatic mutation rates for the putative DNA repair mutant plants.

D) Expose the putative DNA repair mutant plants to a deaminating agent and select those that have a decreased mutation rate.

E) Measure the germline spontaneous and induced mutation rates for the putative DNA repair mutant plants.

Answer:

The correct answer is: A), C) and E)

Explanation:

The breeder wants to isolate the mutants in tomatoes that are defective in DNA repair, to identify such plants breeder should follow these methods as they will allow best to identifying the defective tomatoes-

Measure the somatic mutation rates for the putative DNA repair mutant plants.

Measure the germline spontaneous and induced mutation rates for the putative DNA repair mutant plants.

Expose putative DNA repair mutant plants to ionizing radiation L and see if they survive less well than wild-type plants.  This will allow the breeder to see and analyze the ability of DNA repair in tomatoes

Can someone please describe the role of fermentation in maintaining ATP and NAD+ levels? I cant fully grasp the concept. Answer
Solnce55 [7]
Fermentation is the process by which a carbohydrate molecule is broken down into alcohol and carbon dioxide in the absence of oxygen. During this process, two molecules of ATP is produced. In the absence of oxygen, pyruvate formed from glycolysis will undergo fermentation process. During the process of fermentation, NADH from glycolysis will be converted back to NAD+. This is necessary in order for glycolysis to continue. Thus, fermentation regenerate more NAD+ and only a few molecule of ATP.

Why are nonvascular plants short and small? They cannot adapt to decreased sunlight. They lack tubes for transport and support.
Karolina [17]

Non vascular plants are very small because their lack of a vascular system means they do not have the mechanics required for transporting food and water far distances. ... Non vascular plants are small, simple plants without a vascular system. They do not have a phloem or xylem.
