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:
The digestion of dietary and blood protein.
Explanation:
Encephalopathy is a disease referring to brain damage or malfunction. This means that, a situation whereby the brain is not functioning very well.
This can be caused by drugs, toxins, trauma and infections among others.
In this case, the building up of ammonia in the blood will result to type of encephalopathy known as hepatic encephalopathy. This is when the consciousness level of the brain is being altered.
This happens when the the liver cannot remove toxic chemicals like ammonia from the body.
Answer:
Explanation:
Sequencing the human genome is the function of the human genome project with the goal of determining the base pairs/order of DNA nucleotides that make up human genome, and also identifying and mapping all of the genes of the human genome both from the physical level and its functions in molecular medicine. The benefits in this field could allow for better diagnosis of disease, early detection of certain diseases, and gene therapy and control systems for drugs.
Inborn errors of metabolism are rare genetic (inherited) disorders where the body cannot properly digest and turn food into energy through the normal pathway. The disorders are usually caused by mutations in specific enzymes that help in the break down of these foods.
Through the study of the human genome, sequences involved in these mutations giving rise to these disorders are identified and mapped to their variuos locations. This can help in the early diagnosis of the disorders and effective control system for drugs and gene therapy against these disorders.
