Answer:
Sugars and phosphates
Explanation:
DNA is deoxyribonucleic acid.
The backbone is based on a repeated pattern of a sugar group (deoxyribose) and a phosphate group.
The image below shows one straightened-out strand of DNA with a backbone of alternating sugars and phosphates.
A is wrong. There is no ribose in DNA.
B is wrong. The nucleic acids A, C, G, and T join one strand of DNA to the other.
C is wrong. There is no RNA in DNA.
however the Question is not clear, but, the geosphere is defined as the natural environment we live in. it also controls the minerals distribution, soils and rocks and generate natural hazards that shape the land and impact the lives on earth.
Can certain diseases be hereditary?
Are genetic disorders passed though DNA?
Can we predict certain diseases based on certain chromosomes?
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: A) Increased GI mobility
Explanation: They sympathetic nervous system inhibits the activity if the stomach, therefore, GI mobility decreases and does not increase. The parasympathetic nervous system is the one that increases the GI mobility.
