False.This would cause species to be endangered. When a predator preys on a single prey, it might end up to over-hunting. This will cause a domino effect, if there are no more preys in the area, there is also a big tendency that the predators will die because of the lack of preys in the area, which will eventually lead to extinction of both species.
Answer: Describe investigation involves the act of quantifying segments of a natural system.
Comparative investigation involves the collecting or collection of data on different population under different conditions or basics e.g time, location of the year by making comparisons.
Explanation:
The aforementioned examples are used in investigating variables. Descriptive research aim at accurately and systematically describe a phenomenon or situation, it can answer when, why and how question.
Comparative investigation that is why it is best in research work.
Comparative investigation will give out collection of data variably.
The Lock and Key Analogy of Enzymes and Substrates: Enzymes act as a catalyst in a given chemical reaction (for example, lactase allows lactose to break down into Glucose and Galactose); enzymes lower the amount of energy required to make a reaction occur. There is a key concept to this theory: Enzymes are designed work for only one reaction; there is only one key that fits the lock perfectly. Without enzymes, our bodies wouldn't be able to handle the amount of heat the reactions that occur inside if there weren't any enzymes (or the reactions just wouldn't occur! In the Lock and Key Analogy, the substrate (Lactose in the <span>example) is the "key".</span>
Answer:
earthworms , fishes , frogs , plants and insects .
Explanation:
biotic factors are defined as living things in an ecosystem.
The production of cyclin in the absence of a nucleus means that the cyclin is being synthesized using pre-existing mRNA.
The absence of a nucleus means that the cell does not have its own DNA. DNA is transcribed on to mRNA molecules before the production of proteins. If a protein, such as cyclin in this case, is being synthesized without DNA, this means that the mRNA for the protein already exists in the cell.
