Meiosis involves crossing over where chromosomes exchange genetic segments, resulting in different sets of chromosomes. Each time an egg or sperm created, it is different due to this recombination. Mitosis on the other hand is non-sex cells replicating exact copies of themselves which lead to no genetic variation as they aren't involved in producing offspring.
Answer: Protons contribute towards making ATP by producing proton-motive force that provides energy for ATP synthesis.
Explanation: In the respiratory chain, the transfer of electrons from one complex to another is accompanied by pumping of protons out of the matrix. This creates a difference in proton concentration and separation of charge across the mitochondrial inner membrane. The electrochemical energy inherent in this difference in proton concentration called proton-motive force is used to drive ATP synthesis as protons flow back passively into the matrix through a proton pore.
Answer:
Bacterial population shown in the graph is of Exponential type.
Explanation:
When the rate of population increases over time in proportion to the population size, it is known as exponential growth of population. Bacterial reproduction happens in an hour time span for many bacterial species by splitting itself in half.
This shows how the exponential growth occurs in bacteria. The amount of population gets increased with added organisms in generations of species.
