RNA is a copy of DNA that is used to make proteins. We usually compare all eukaryotic cells as a group to all prokaryotic cells.
<span>Crossover is the first way that genes are shuffled to give rise to genetic diversity. Crossover takes place in sexual reproduction. Chromosomes line up side by side and break off pieces of themselves, then trade those pieces with each other. When they break at the same place (locus) in the sequence of base pairs, the result is an exchange of genes called genetic recombination. That is the normal way for crossover to occur. Genetic recombination ensures that the daughter cells produced have a different genetic makeup from the parent cell and thus diversity is created.</span>
Answer:
Well.
Explanation:
Recycling can prevent <em>more </em>plastics and other products that are harmful to the environment from being made. Because we are recycling the products so we can't make more of it.
Answer:
C. Liquid molecules and atoms are able to slip around each other and fill in gaps between them.
Explanation:
The liquid is a state of matter that has no definite shape. In fact, it can adapt to the shape of its container. This is because of the reason that molecules in the liquid phase have high kinetic energy and weak binding forces. The high energy keeps them moving freely and thus can take the shape of it its container. On the other hand, in solids, the binding forces are stronger and molecules have very little energy to move freely.
Example: If we melt a solid, the molecules initially have less energy. However, when we heat them, they gain energy and start moving. Upon further heating, they will have enough energy to break the bondings and move around. This is why the solid structure will change to the liquid.
Answer:
Enzyme is a catalyst
Explanation:
Enzymes make the chemical reaction faster than usual because the activation energy required for a substance to react becomes low with presence of enzymes. if we don't have enzymes it may result to slow metabolic processes. some environmental factor can affect enzymes like over exposed to radiation can activate the enzyme causing it to disrupt. or consuming a mutagenic agents that may affect the enzymes activities.
