I think it’s D bc it’s talkin about fossil fuels
Answer: Gene flow is the movement of alleles from one population to another as a result of the migration of individuals. This causes a reduction in the differences between populations. ... Genetic drift is a change in allele frequencies due to change of events in a small breeding population.

Enzymes are typically composed of amino acids.
Enzymes specifically binds to their substrate, and accelerate the biological or in-vitro reactions.
Four real-life examples of enzymes are: Lipase, Maltase, DNA ploymerase and Alcohol dehydrogenase.
Explanation:
All enzymes are proteins. They are composed of amino acids as monomer units linked by polypeptide bonds.
The substrate is a molecule which has specific enzyme binding sites for the highly specific enzyme called as active sites. With this binding, the enzyme-substrate complex is formed, undergoes the chemical reaction and new product is formed. Enzymes accelerate the biological reactions by lowering the reaction's activation energy.
Four-real life examples of enzymes are:
Lipase enzyme: catalyses the hydrolysis of fats and triglycerides in the small intestine. Lipase enzyme is secreted by pancreas.
Maltase enzyme: catalyses the breakdown of maltose sugar. It is secreted by salivary glands and our mouths.
DNA Polymerase Enzyme: It catalyses the DNA replication in the cells. It is secreted by the nucleus
Alcohol dehydrogenase: It catalyses many reactions in the body as the reduction of NAD to NADH. It is secreted by the liver.
Hello, Christylucia96!! Your best answer would be C - Stellar evolution. Nuclear fusion is what powers the stars. Nebular clouds are a bunch of stars, also where they are born. Stellar means star and evolution means changes throughout time. The Big Bang Theory states that space began with a few stars and an explosion happened, which created a bunch of different stars that we have today. I hope I helped!! Have a great evening!!
