23, half of the total. This is because a zygote receives 23 from the mother and 23 from the father.
Answer:
Explanation:
It is carried out by nitrogen-fixing bacteria. The bacteria live in soil and roots of legumes, such as peas. When plants and other organisms die, decomposers break down their remains. In the process, they release nitrogen in the form of ammonium ions.
Answer:
The production of new life through offspring by a sexual or asexual process.
Explanation:
<span>It depends upon what type of cell which underwent the division.
If it is a somatic cell and it underwent mitosis, the number of chromosomes remains
unchanged at 46 in each cell. On the other hand, if it is a sex cell, the
number of chromosomes is halved (23) after meiosis. By the way, mitosis is the
term for cell division among somatic cells and meiosis is for the sex cells.</span>
The correct answer is B. Electron transport.
The electron transport chain is the terminal step of aerobic respiration. It occurs on the inner membrane of the mitochondria. Reduced coenzymes NADH and FADH₂ are produced during glycolysis and Krebs cycle. When NADH and FADH₂ move along electron transport chains, high-energy electrons are released from NADH and FADH₂ produce ATP. The final electron acceptor in the process is free oxygen. Each NADH produces 3 ATP and each FADH₂ produces 2 ATP. Therefore, a total of 32 ATP molecules are generated in electron transport. Therefore, the electron transport system releases a lots of energy for cheetah to run fast.
