Why do rats have three lobes of liver and humans only have one?

Answers

Answer 1

Answer:

Although the rat liver is typically lobated2 and its ap- pearance does not resemble that of the human liver, the hepatic lobes of the rat liver have been found to be equivalent to the sectors of the human liver. As rats and humans belong to the class Mammalia, similar em- bryological development is expected.

Explain what scientists might be able to learn about the seawater that existed millions of years ago by studying rocks that came into contact with seawater at that time in the past . Use evidence from the text to support your inference.

Answers

Answer:

About composition of water and organisms that lives there.

Explanation:

scientists might be able to learn about the composition of seawater that was present millions of years ago if we study those stones that comes in contact to that ancient seawater because the traces of particles still present on it. This study provides valuable information about ancient times of earth and its natural resources. These rocks also provides animals that were present in that sea water at that time.

Geologists using the aspects of geology and paleontology can study and analyze the evolutionary, physiology and ecological relation of plants, animals and other microorganisms with abiotic and other biotic factors.

The scientists will be able to understand the composition of the organism and the water that resided in the region.

This inference can be supported by:

The stones and rocks present in the seawater will depict the characteristics as they will have traces of particles present on them from the past years.

This evaluation will provide insights into the natural resources and organisms present during the ancient times on the planet.

This will also give data about the organism living in aquatic or terrestrial areas.

Therefore, it will give the composition of water and organisms.

There are now several effective antimalarial drugs that can treat people who have malaria or prevent them from getting the disease altogether. Predict what will happen to the frequency of the sickle cell allele over the next 100 years as these drugs become more widely used by people living in areas where malaria is endemic: _____________ Predict what will happen to the frequency of the sickle cell allele over the next 100 years in areas like Boston MA, where there is no incidence of malaria: __________ stay the same ; stay the same decrease ; increase increase ; increase increase ; decrease decrease ; decrease

Answers

Answer:

decrease, decrease

Explanation:

By using antimalarial drugs in order to prevent malaria, the frequency of the sickle cell allele decreases in both areas where malaria is endemic and the areas where no incidence of malaria occurs because there is no necessity of sickle cell allele in the population to prevent malarial disease. Sickle cells have high significance in prevention of malarial diseases so when there is no malaria happens in the population so there is no need for it and the allele slowly removed from the population and decrease occurs in its frequency.
