Answer:
Mechanical Isolation
A snail with a flat disc-like shell
will not be able to mate with a
snail having a conical shell.
The reproductive organs of
male bush babies do not
match with the reproductive
organs of females of other
bush baby species
Behavioral Isolation
The mating call of a cricket is not
recognized by a cricket of other
species.
The signals sent by a male firefly
are not recognized by the female
firefly of other species.
Explanation:
Mechanical isolation occurs in the scenario where two organisms are willing to mate but cannot do so due to the physical challenges. As in the case of snail a flat disk and a conical disk snail are willing to mate but physical barriers restrict them in doing so.
The same case is with the male and female bush babies where the difference in reproductive organs does not allow them to mate.
Behavioral isolation represents a scenario where two organisms are unaware of mating rituals, season, pattern or signals of each other and hence cannot mate.
For example – male and female cricket do not recognize the mating call of each other. Likewise male and female firefly is also not able to understand each other’s mating signal.

Answer:
To obtain a view of an individual's karyotype, cytologists photograph the chromosomes and then cut and paste each chromosome into a chart, or karyogram, also known as an ideogram. In a given species, chromosomes can be identified by their number, size, centromere position, and banding patter

Answer: b. can lead to other cardiovascular diseases
Explanation:
High blood pressure or hypertention can be define as a condition in which the flowing blood exerts force over the walls of the arteries. The arteries are the type of blood vessels which carries the blood from the heart to the rest of the body parts. This condition results in heart diseases like heart stroke or heart attack due to abnormal blood flow.
Answer: The appropriate information that will be used to fill the blanks includes the following respectively:
-1.7
- increased
-70%
- 0.5
- decreased
- 50%
Explanation:
The green (topmost) data point at June 2011 shows a proportional change of about 1.7, which means that the native fish population INCREASED by about 70 percent when 95 percent of the lionfish were removed. In contrast, the orange data point at June 2011 shows a proportional change of about 0.5, which means that the native fish population DECREASED by about 50 percent when only a quarter of the lionfish were removed (a result that was almost the same as when none of the lionfish were removed).
The native fishes are being haunted by the lion fish, from the results, removing just few of the invasive lion fish will not make a difference. In other to help the native fish survive, many of the lion fish has to be removed.
