Answer:
There is some debate about the definition of a species, especially across fields. However, what it likely being discussed here is the biological species concept which states that:
An organism is considered a new species when there is reproductive isolation from the population that they originated from. In other words, for two organisms to be the same species they must be able to reproduce to create viable (able to survive) and fertile (able to reproduce) offspring.
Reproductive isolation can occur by different means, classified as being prezygotic or postzygotic isolation. These include things like mechanical, behavioral, temporal, ecological, and geographical isolation for prezygotic isolation. And things like hybrid infertility and hybrid inviability for postzygotic isolation. These are not relevant to the question but they give you an idea of what you could look up if you wanted more information.
Answer:
A. Limits to resources exist for a population
Explanation:
<em>The explanation that fits the growth curve would be that there exist limits to the resources available for the population.</em>
As a result of limited resources, a population is prevented from reaching its biotic potential and confines the population growth model to logistic rather than exponential.
The limited resources keeps the population around the carrying capacity of the environment, that is, the maximum population size an environment can support based on the resources it has.
<u>A newly established population usually experience a short period of exponential growth. As a result of continuous competition for resources, the population becomes limited and begins to oscillate around the carrying capacity of the environment.</u>
The correct option is A.
Answer:
D. Two strands of DNA linked together
Explanation:
nucleotide join together to form a DNA molecule
Hi
- a: Substrate
- b: Active site of the enzyme
- c: Enzyme
- d: Products
The picture depicts an enzyme mediate reaction.
Enzyme is the proteinaceous substance that increases the rate of chemical reaction by binding to the substrate.
Substrate is the reactant of the reaction which is processed by the enzyme into a product at a faster speed than the normal reaction.
Active site is the specific part of the enzyme where a substrate binds and chemical reaction occurs. it is also known as catalytic site because it contains residues that formulate short term bonding with reactants or substrate molecules and then catalyse the reaction.
Products are the final outcome of an enzymatic reaction which are formed after the completion of reaction and are desired substances from reaction.
