Answer: B. Speed up the chemical reaction
Explanation: Enzymes help speed up chemical reactions in the human body. They bind to molecules and alter them in specific ways. They are essential for respiration, digesting food, muscle and nerve function, among thousands of other roles.
Kelp populations would be entirely depleted and it would impact the sea life that thrive off of kelp as their homes and source of food. Many sea creatures use kelp as a sort of barrier to prevent bigger fish from attacking them.
Answer:
Scientists mostly gain new knowledge through direct observation and applying the scientific method. They would start with a hypothesis and test it, then change it or confirm it. Others would test their confirmation from one point, while the third group would test what the second said. And so on and so forth.
Explanation:
Answer:
1. Substitution
2. Insertion and deletion
3. Amino acids can have more than one codon that signals for it. Due to this, some substitutions don’t affect the protein at all.
Explanation:
1. Substitution sometimes isn’t as impactful. It can result in the same amino acid to be signaled as the original one since amino acids can have more than one codon signaling for it.
2. Insertion and deletion are also known as frameshift mutations. This is because they shift the codon spots by adding or deleting a nucleotide.
Answer:
Cell wall, chloroplast, and central vacuole
Explanation:
Cell wall, chloroplast, and central vacuole are present in a plant cell but not in the animal cell.
Nucleus, cell membrane, and cytoplasm present in both plant and animal cells.
