CAM photosynthesis limits CO2 fixation to nighttime hours in order to (A) allow water to enter leaf spaces during the daylight h
bixtya [17]

Answer:

(B) open stomata only at night, limiting water loss because of heat and low humidity.

Explanation:

CAM plants are found in the regions characterized by very hot and dry environmental conditions. These plants reduce the water loss through transpiration by exhibiting CAM photosynthesis.  

They open the stomata during night time when the air is cooler and rich in moisture. They take in CO2 during night time and fix it into the oxaloacetate which in turn is converted into malate and is stored in the vacuoles.  

During day time, stomata remain closed to prevent water loss and the CO2 trapped during night time (released by decarboxylation of malate) enter the Calvin cycle.

How does a magnifying glass make an object look bigger and closer?​
ANEK [815]

Answer:

Any converging lens that has a small focal length (several centimeters) can be used as a magnifying glass. The observed object is placed in front of the magnifying glass so that it is located between the lens and the focus (closer to the focus).

Explanation:

It consists of only one condenser lens of small life (a few centimeters).

The observed object is placed between the magnifying glass and its focus (closer to the focus)

The observer sees an upright and enlarged figure of the object.

In order to like clear video ("sharpen"), the magnifier zooms in or out of the subject.

When the character is most clearly seen, we can find ourselves on a given high species.

For a man with normal eyesight, it is about 25 cm.

Mazyrski [523]
