Answer: Mass flow or bulk flow is the movment of substance in big masses or something moving in a big group.
Explanation:
Its kind of like a river or blood flowing through your veins because its a mass of a substance moving in a group.
The correct answer is option D. Prophase I
The crossing over is a phenomena, which occur in the cells undergoing meiosis. In the process of crossing over, the exchange of the genetic material takes place between the sister chromatids. This process takes place in the prophase 1 stage of meiosis 1 in the gametes. The exchange of genetic material between chromatids cause recombination, and hence, genetic variation.
Answer: Sun, clouds, vegetation or plants, little wind, Hill.
Explanation:Riding on my bike,towards the top of the hill, I know water cycle is happening, this is evident first from the SUN which had risen in the morning, heats up the LAKES ( water body ) while also providing energy for PLANTS which gives off water vapor through transpiration. That vapor then evaporates to atmosphere to form bright CLOUDS. because it is a warm summer day , there is less WIND which does not move the clouds to form rain. The big gulp of COLD WATER I saw on the HILL should be from the result of accumulated rain water. This will gradually infiltrates into the GROUND to return to the ocean. And thus cycle continues.
The water cycle, therefore is a continuous movement of water on every part of the surface of the Earth by processes of evaporation, condensation, precipitation, infiltration, surface runoff, and subsurface flow through different forms of liquid, solid (ice) and vapor.

Answer:</h2>
Option 3rd. anaerobic process that breaks down glucose
<h2>
Explanation:</h2>
- On observing only glycolysis it is an anaerobic process. As none of the nine steps of glycolysis involve the use of oxygen.
- After, immediate finish of glycolysis, the cell continues respiration either in anaerobic or anaerobic direction this depends upon the presence of oxygen and mitochondria.
- If oxygen and mitochondria is present the glycolysis will be broken down to produce 2 molecule of pyruvate as the end product which will be utilized in further processes(in kreb's cycle and ETS).
- In case if oxygen is absent then different types of alcohols and and acids are formed.
Result: Glycolysis does not involve oxygen and hence is a anaerobic process.
Somatic cell chromosomes (body cells) are in pairs. if you mean 12 chromosomes,Then there will be 6 pairs, groups of two, chromosomes. The gamete (aka sex cell) will thus contain 6 chromosomes.
One chromosome from each pair ends up in one gamete, normally.
