Sloan [31]

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.

Dan has noticed that when he adds fertilizer to his garden soil his strawberry plants seem to grow better. Dan wonders if it is
madreJ [45]

The correct answer is - the variable.

With the experiment, in the way that Dan had decided to perform it, the fertilizer is the variable, as in one of the parts with strawberries he uses fertilizer, while in the other part he doesn't uses fertilizer.

While this kind of experiment may give Dan some answers, and he might notice differences, still he would have to be more detailed in the experiment to see for sure if the fertilizer is the thing that makes some of the strawberries grow better than the others.

Dan should also put all of the strawberries at places that would receive the same amount of light, experience the same weather conditions, receive the same amount of water, and to be planted in a soil of the same quality. Only like this, after putting the fertilizer, Dan can now if it makes any changes or not.

<h2>The following scenarios state whether the mutation is likely to be passed on to the offspring of the organism or not: </h2><h2> </h2>
  • a. A single bacteria cell contains a positive mutation in its DNA - The mutation is likely to pass as it is a unicellular organism with the cell itself containing the positive mutation.

  • b. A skin cell on a cat contains a positive mutation in its DNA - The mutation is not likely to pass as it is the skin cell.

  • C. A sperm cell in a whale contains a positive mutation in its DNA - The mutation is likely to pass as it is in the sperm.
