Answer: a. Stomata open at Night

Explanation:

As a tactic to minimize photorespiration in warm regions, many water-storing plants such as cacti and pineapples modified its method of carbon fixation. This process is called Crassulacean Acid Metabolism (CAM), following the plant family Crassulaceae, in which it was first identified. In these plants, the stomata (singular, stoma), specialized openings in the leaves of all plants through which CO2 enters and water vapor is lost, open during the night and close during the day. This model of stomatal opening and closing is the opposite of that in most plants.

The Energetics of Coupled Transport
andrezito [222]

Answer:

Explanation:

A. False - A symporter system requires that one of the molecules to be transported using passive transport.

B. True - The Na+ will move down the established concentration gradient releasing energy to facilitate movement of sucrose against its concentration gradient. This is known as secondary active transport.

C.  False -  sucrose moves through ion channels not by diffusion to better control its movement across the membrane.

D. True - Movement of molecules against their concentration gradient thus requiring energy input is known as active transport.

E. False - One of the molecules needs to be moving against its concentration gradient.

F. False - A Uniporter system allows the binding and transport of a single molecule at a time. A symporter allows simultaneous binding and transport of Na+ and sucrose molecules.

Describe the mutation in a plant that could have a negative outcome for the organism
iris [78.8K]
A mutation in a plant that could cause negative outcomes could be the plant has less leaves, or isn't hardy enough, like other plants. It would die. A plant from an area like Chernobyl, that has been affected by radiation could poison other animals, or pass that gene along, and ultimately kill that strand of plant.

If the characteristic is eye color, what could be two different phenotypes?
Feliz [49]
The phenotype is just a characteristic/trait. 

For instance Brown and Green are phenotypes of eye color. 

This can also be used in Punnet Squares, and could be displayed as B and G. 
B equaling dominant Brown, and G = dominant Green, vice versa to g and b where they are recessive.
