Answer:
Basal meristems
Explanation:
Meristems are the portion of plants able to generate any kind of new tissues. Therefore, the way plants keep their meristems protected is related to climate adaptation.
Grasslands tend to be arid ecosystems, so grasses have developed basal meristems, meaning they spend the dry season very close or under soil, where water evaporates slowlier than above surface, until wet season allows meristems to generate new stems and leaves.
This disposition is also useful in cases of fire and grazing, which are also frecuent in grasslands.
Answer:
D
Explanation:
Extracting DNA involves firstly harvesting the required cells (such as from the inside of cheeks), then the cells are broken up using enzymes or detergents. The products (usually a mixture of cell products –mainly RNA, DNA, and proteins) are then put in a centrifuge to separate the proteins from the DNA.
Answer:
Inbreeding and greater chance of passing deletereous mutations through generations
Explanation:
There are several reasons why small populations are more prone to genetic diseases. One of them is that in small populations there tends to be more inbreeding
, that is breeding between individuals are closely related. Inbreeding increase the chances of offspring being affected by deletereus homozygous genotypes.
On the other hand, the acquisition of a deleterious mutation in a small population is more likely to be spread in that small population than in a large population.
Answer:
Photosynthesis
Explanation:
This is a role in the cycling of matter and flow of energy into and out of organisms. The flow of energy and cycling of matter can be traced.
Food is moved through the digestive system by a process called peristalsis<span>.
