Explain the role of a hypothesis in a scientific investigation.
k0ka [10]

Answer:

A hypothesis is a testable proposition

used to explain scientific phenomena. It

may be based on previous observations

(a sort of educated guess) or it may

simply be a hunch. Most scientific

hypotheses are combinations of

observation and intuition. The important

thing is that the hypothesis be testable.

If the hypothesis is disproved through

testing, then it is discarded and a new

hypothesis is proposed. If the hypothesis

stands up to rigorous testing, then our

faith in the hypothesis is increased.

This system of careful, rigorous, and

unbiased testing of a hypothesis is what

characterizes the scientific method.

Hope it helps!

Which of the following can affect the function of a cell?
AnnyKZ [126]

Hi there,

The answer to this question is

D. All of these

Changes in different temperature and acidity can change the function of a cell. Acidity and Temperatures are usually balanced for the cell function but one small change in one of them can throw off the cell of the pH levels.

Hope this is correct :)

Have a great day

A species of elm has winged-seeds. How would biologists explain how a species of elm with winged-seeds evolved from an ancestral
dimaraw [331]

Answer:

In an ancestral elm species, mutations gave rise to the phenotypic trait "winged-seeds". Subsequently, selection favored elm plants with winged-seeds that diverged over time to become a separate species

Explanation:

A mutation is a genetic change in the DNA sequence. In general, mutations have a negative impact on the fitness of the individual (i.e., mutations are generally deleterious) and therefore they disappear from the population. However, there are situations where mutations are beneficial and confer an adaptive advantage, thereby increasing their frequency in the population. In this case, mutations associated with the formation of winged-seeds conferred an adaptive advantage (i.e., higher seed dispersal capacity) to individuals who had this phenotypic trait, thereby these individuals had more chances to reproduce and pass their genes to the next generation. Eventually, Elm plants with winged-seeds accumulated sufficient genetic differences to prevent interbreeding, leading to the formation of a separate species.

You could say variation in offspring (so cloning things they basically just multiple the exact same thing but with reproduction, whatever is made differs a little bit or a lot from its "parents"
