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.
The twisty columns of the double helix are phosphate and sugar(deoxyribose), which are bonded by a covalent bond. Each nucleotide consists of one of each, and also a nitrogen base. The rungs are nitrogen bases, each nucleotide has one base, and one side of the ladder bonds to the other side of the ladder through hydrogen bonding of complementary base pairs. The base pairs of DNA are A-T and C-G
Answer:
There are two types of melanin--eumelanin and pheomelanin. In general, the more eumelanin in your skin, the darker your skin will be. People who make more pheomelanin than eumelanin tend to have lighter skin with freckles. Like many other traits, the amount and kind of pigment in your skin is controlled by genes
