Answer:
20,000 genes...
Explanation:
<h3><em>Human genes vary in size from a few hundred bases to over a million bases..So every human has 20,000 genes and 3,000,000,000 bases.Your entire sequence of genes and bases is called
genome..</em></h3>
The answer is An object is in motion if it changes position relative to a reference point. You assume that the reference point is stationary, or not moving.
Answer:
The Oxygen liberated in photosynthesis comes from photolysis of water.
The CHO formed from Calvin Cycle during photosynthesis comes from reduction of CO2 with H+ of photolysis of water.
Therefore,since Plant 1 contains labeled Oxygen(from water) it will give radioactive Oxygen as the byproduct of its photosynthesis. It CHO is normal.
However,Plant 2, will contain radioactive CHO,because its radioactive CO2 will be reduced by H+ from photolysis of water to form radioactive labeled carbohydrate(CHO)
Explanation:
The condensation of water vapor formed the early oceans. It is an important part of the water cycle. It is easy to eliminate the other answers in this question. It can't be meteorites, living organisms, or nitrogen.
2. The endosymbiotic theory suggests that a eukaryotic cell is the result of one prokaryotic cell eating another.
