On the Galápagos Islands, Charles Darwin observed Question 1 options: completely unrelated species on each of the islands. species exactly like those found in South America. species similar to mainland South American species. species completely unrelated to those found in South America.

Answers

We can confirm that on the islands, Charles Darwin observed species similar to mainland South American species and to those found on the other islands.

What did Darwin notice about these species?

Darwin noticed that each of these species were very similar, but possessed slightly different traits. These traits seem to perfectly fit the needs of each species for their specific island, leading to his creating the theory of evolution through natural selection.

Therefore, we can confirm that on the islands, Charles Darwin observed species similar to mainland South American species and to those found on the other islands.

·Why does it make sense that blood flow varies throughout different organs

Answers

It is important that blood flow varies throughout different organs because of differences in the metabolic activities of the different organs.

What is the circulatory system?

The circulatory system refers to the system of organs and tissues which are involved in the circulation of blood around the body.

The circulatory system performs the essential function of delivering nutrients to tissues and cells as well as removing metabolic waste from them.

Since the different organs in the body perform specialized functions, some organs are actively involved in metabolic activities, therefore need greater blood flow.

Therefore, blood flow varies throughout different organs because of differences in their metabolic activities.

eukaryotic. If the cell has nucleoid or indefinite
nucleus and without membrane-bound cell

Sally made a diagram to show one way that Earth's systems interact near a volcano

1. Identify the process that sally is moldering in her diagram

2. Explain how the individual parts shown in the model come together to form a cycle

Answers

The process that Sally is modeling in her diagram is the "Role of Volcanoes in the Earth's Systems". This particular system is called "the Cycle of Rock and Soil formation"

How do the individual parts of the model form the cycle?

The cycle of soil formation starts with the production of molten magma by the volcano.

The magma solidifies and cools, then they are transported, deposited and go through lithification.

After lithification, they become sedimentary rocks, and then through exposure to pressure, they become metamorphic rocks.

Over the years, as more and more layers are deposited onto the metamorphic rocks, pressure and heat build up creating molten magma.

The magma creates igneous rocks which after many years may be produced again as molten magma through an active volcano.

It is very efficient because the person can eat less.
It is inefficient because less energy is needed at the top.
It is very efficient because most energy is made by producers
Only a portion of energy from vegetation makes it to a person.

Answers

Answer:

It is very efficient because the person can eat less.

Explanation:

the common knowledge answer

Only a portion of energy from vegetation makes it to a person. The correct option is D.

What is energy efficiency?

The definition of energy efficiency is the use of less energy to carry out a task or achieve a goal.

Ecological efficiencies at each trophic link determine the food chain efficiency (FCE), which is calculated as the percentage of energy fixed by primary producers that is transmitted to the top trophic level.

The energy supply accessible to trophic level N+1 divided by the energy used by trophic level N is the definition of ecological efficiency.

Only a percentage of the energy from vegetation makes it to a person, which best sums up the efficiency of energy transmission in this situation.

Thus, the correct option is D.

What color hair do the parents have?

A. One has blonde and the other has brown

B. Brown

C. Blonde

d. unable to determine

Answers

Given what we know, we can confirm that the parents have brown hair.


Why do the parents have brown hair?

This has to do with how dominant alleles work. When an allele is dominant, it is because, in the presence of mixed alleles, this trait will always be the one reflected in the phenotype of the individual. Since the parents possess an allele for brown hair and one for blonde, but brown hair is dominant, both parents will have brown hair.

Therefore, we can confirm that both parents will have brown hair due to the dominant nature of the brown hair allele.
