Answer:
Rare species of plants can be cloned so they don't go extinct. To do this, stem cells are taken from the <u>meristems</u> of the plant.
Explanation:
Stem cells can be described as cells which are undifferentiated and have a capability to divide into specialized cells. In plants, the stem cells are located in the meristems of the plant. Out of these cells, all the specialized tissues and organs form in a plant.
Cloning is a method to produce identical copies of a gene or an entire organisms. The method of cloning is now being used widely to make organisms that are at the verge of extinction.
Answer:
There are two ways plants can achieve this. First, they can minimize the resistance to diffusion of CO2 through the stomata (i.e., have lots of large, open stomata). Second, they can maximize the biochemical rate of fixation (i.e., have high concentrations of photosynthetic enzymes).
Sometimes when the moon orbits Earth, it moves between the sun and Earth. When this happens, the moon blocks the light of the sun from reaching Earth. This causes an eclipse of the sun, or solar eclipse. During a solar eclipse, the moon casts a shadow onto Earth.

Explanation:
glaciers cause erosion in two main ways, plucking and abrasion. they freeze to the bottom of the glacier and they are carried away by the flowing ice. abrasion is the process in which a glacier scrapes underlining Rock. the segments and rock Frozen in the ice at the bottom and slides of a glacier act like sandpaper
