a) precipitation is balanced by evaporation
primary division of the sea, which includes the whole mass of water subdivided into neritic and oceanic zones; also pertaining to the open sea (open water)
Answer: B (GTP serves as the energy input for AMP synthesis from IMP)
Explanation:
In the de novo synthesis of purine nucleotide, IMP represents a branch point for purine biosynthesis. IMP can be converted to either AMP or GMP.
The formation of AMP from IMP requires GTP; similarly formation of GMP requires ATP. The conversion of IMP to either AMP or GMP is highly regulated – AMP and GMP inhibits their own formation by feedback inhibition of adenlyosuccinate synthetase and IMP dehydrogenase.
Answer: The shoot grows up towards the sunlight is Positive Phototropism
The root grows down the soil is Positively Geotropism / positive gravitropism.
happy to help again :)
Answer;
D. Most of the energy from photosynthesis flows out as heat
Explanation;
Energy flow is the amount of energy that moves through a food chain in a given ecosystem.
Producers such as green plants in a ecosystem convert energy from the the sun into carbon bonds, such as those found in the sugar glucose through the process of photosynthesis.
The amount of chemical energy storied as nutrients in the bodies and wastes of organisms flows through ecosystems from one trophic level to the next and through this flow energy also is lost as heat. And the chemical energy available to the succeeding feeding level decreases.
