Answer:
please put a picture of the work you have to do so i can help you
Explanation:
Imagine you are surveying a population of a mountain range where the inhabitants live in the valleys with no inhabitants on the large mountains between. If your sample area is the valleys, and you use this to estimate the population across the entire mountain range, <u>you overestimate the actual population size</u>
<u />
Explanation:
- An estimate that turns out to be incorrect will be an overestimate if the estimate exceeded the actual result, and an underestimate if the estimate fell short of the actual result.
- The mean of the sampling distribution of a statistic is sometimes referred to as the expected value of the statistic. Therefore the sample mean is an unbiased estimate of μ.
- Any given sample mean may underestimate or overestimate μ, but there is no systematic tendency for sample means to either under or overestimate μ.
- Bias is the tendency of a statistic to overestimate or underestimate a parameter. Bias can seep into your results for a slew of reasons including sampling or measurement errors, or unrepresentative samples
The stage is the last stage of speciation The populations become adapted to different environments and eventually become so different that they cannot interbreed to produce fertile offspring.
Speciation is split into 3 stages:
a) Separation.
b) Adaptation.
c) Reproductive Isolation.
Stage 1 Separation
- A part of the populace separates and adapts to a brand new environment. Natural occasions along with tsunamis, tidal waves can reason organisms to split from their preliminary habitat to a brand new environment.
Stage 2: Adaptation.
- At this stage, the organisms evolve new trends that permit them to a brand new environment. They own sure traits that permit them to match into the brand new environment. Example The notable white skin's color makes it tough for it to be visible withinside the dark.
Stage 3: Reproductive Isolation.
- At this stage, organisms of the equal species reunite and do now no longer interbreed. e, species are remoted into new ones in order that they have the great diversifications for or her new habitat.
<h3>What is speciation?</h3>
Speciation is an evolutionary method where the new species arises from previous ones.
Hence concluded that speciation involves the stage where the populations become adapted to different environments and eventually become so different that they cannot interbreed to produce fertile offspring.

Answer: To eliminate bacteria that failed to take in the plasmid.
Explanation:
Research shows that plasmid DNA is only taken in by small percentage of bacteria in a large population.
Therefore, the need of growing transformed bacteria in the presence of ampicillin is very important. The main reason of this process is to kill off or eliminate bacteria that have failed to take in the plasmid, due to their possession of recombinant DNA plasmid pARA-R (an ampicillin resistance gene), that allows them to survive.
However, after completion of the aforementioned procedure, the bacteria that have been transformed will be able to take in the plasmid.
This is because they lost nearly 30 to 50 ml of blood every month during menstruation and some even 80 ml.
And also the metabolism of females is lower than males due to low rbc count in hormones.
