Answer;
Hot & Dry conditions
Explanation;
-C4 is the alternative pathway of Calvin cycle (C3 cycle) taking place during the dark phase (light-independent stage) of photosynthesis. In the C4 cycle the first stable compound is 4 carbon compound, namely oxaloacetic acid. Hence it is called C4 cycle. It is a process of carbon dioxide fixation.
-C3 plants have the disadvantage that in hot dry conditions their photosynthetic efficiency suffers because of a process called photorespiration. When the CO2 concentration in the chloroplasts drops below about 50 ppm, the catalyst rubisco that helps to fix carbon begins to fix oxygen instead.
-The problem of photorespiration is overcome in C4 plants by a two-stage strategy that keeps CO2 high and oxygen low in the chloroplast where the Calvin cycle operates.
Each gamete gets just one crest allele. Half of the gametes will get one of the parent's alleles, and the other half will get the other allele. The Punnett square shows the possible crest allele combinations in the offspring. There are 4 possible combinations in all.
plz mark me as brainliest :)
Conduction, it is direct contact from the hand to the hot coal.
Answer:
Gravity
Explanation:
When its altitude is matched by the pull of the Earth's gravity, a satellite circles Earth. The satellite will fly off into orbit in a straight line or crash down to Earth without this equilibrium.
By juggling two things, a satellite retains its orbit: its velocity (the speed it takes to travel along a straight line) and the gravitational force on it that the Planet provides. To resist the greater gravitational force, a spacecraft orbiting closer to the Earth needs more velocity.
2,996 people were killed and more than 6,000 others were wounded during the attacks, moment of silence for all those poor people and their families.
