I think B. would be your answer :)

Answer:
Impact as greenhouse gases
CFCs were phased out via the Montreal Protocol due to their part in ozone depletion. However, the atmospheric impacts of CFCs are not limited to their role as ozone-depleting chemicals.
Explanation:
Answer: Crossing-over allows the genes that come from each parent to recombine before they are passed on to future generations because chromatids of homologous chromosomes mate and exchange sections of their DNA.
Explanation:
Chromosome crossing-over is the process by which chromatids of homologous chromosomes mate and exchange sections of their DNA during prophase I of meiosis, when pairs of homologous chromosomes, or of the same type, are aligned. The chromatids of the homologous chromosomes break off in the chiasmas and rejoin to allow recombination of the linked genes. So it occurs when regions at chromosome breaks mate and then reconnect to the other chromosome. <u>The result of this process is an exchange of genes, called genetic recombination</u>.
This allows the genes that come from each parent to recombine before they are passed on to future generations. Then, <u>it is an important source of genetic variability</u>, since it involves an exchange of segments between homologous chromosomes during the development of gametes. <u>This process allows that the descendants of an individual are genetically very different</u>, since it is very unlikely that an individual produces two equal gametes, because all of them have different segments of the homologous chromosomes.
Answer:
Active site.
Explanation:
Inhibitors may be defined as the chemical that can binds with the substrate and inhibits the reaction. The competition can be overcome by adding the large amount of substrate.
The inhibitor compete and binds to the active site of substrate. This decreases the rate of the reaction and may inhibit it also. The target molecule is unable to binds with the substrate and inhibitor blocks the active site of the enzyme.
Thus, the correct answer is option (a).
Answer:
Energy (in the form of ATP)
Explanation:
The main difference between active transport and passive transport is that active transport needs the energy to work. Active transport also moves molecules against the concentration gradient, kinda like a pump. This pump will need energy in the form of adenosine triphosphate (ATP) to keep it working. Adenosine triphosphate will be broken down into adenosine diphosphate (ADP). The energy from the breakdown reaction will be used by the pump.
