If two species have many amino acid differences, are they closely or distantly related? Explain how scientists know this.

Answers

Answer 1
Different amino acids means difference DNA sequences, which means they are distantly related.

Further understanding: if you look at identical twins, they are closely related to each other because they have almost the same DNA, which will code for the same amino acids, which will lead to the same phenotype or appearance.

To summarize, the greater the amino acid differences the less related they are and vice versa

Hope that helps

Answers

Answer:

The offspring will be black because they are heterozygous for a dominant trait that is controlled by monogenic inheritance.

Explanation:

Guinea pigs will be heterozygous because they inherit a dominant allele that encodes for the black color and a recessive allele associated with the white color. Heterozygosity is a genetic condition associated with the presence of two alleles at a locus which are inherited from both parents, one from the mother and the other from the father

How do the respiratory and circulatory systems work together to make gas exchange possible?Giving brainliest to first right answer

Answers

Answer:

Answer: The respiratory system moves air in and out of the body. When you breath in oxygen this creates oxygenated blood. The blood moves through the aorta which then distributes the oxygenated blood to rest of the body. The co2 then leaves the lungs when you exhale. Hope this helped. :)

Explanation:

Answer: [SAMPLE RESPONSE] The two systems work together in several ways. First, the respiratory system brings oxygen in the air to the alveoli in the lungs. The circulatory system then delivers the oxygen to the cells. Second, the circulatory system picks up carbon dioxide from the cells and carries it to the lungs, where it is released when we exhale.

Why do land plants need to conserve water

Answers

Answer: Some arid-climate plants are able to conserve water because of their reduced leaf size. Less leaf surface area results in reduced water loss through the epidermis. Small leaves have fewer stomata than larger leaves, and that adaptation also reduces water loss.

Why is the nitrogen cycle important for the survival of organisms in an ecosystem? A. The nitrogen cycle recycles nitrogen through an ecosystem, making it available to all organisms. B. The nitrogen cycle keeps organisms from consuming nitrogen in their ecosystem. C. The nitrogen cycle allows all organisms in an ecosystem to consume nitrogen instead of consuming each other. D. The nitrogen cycle stores nitrogen in safe places, keeping it from entering an ecosystem.

Answers

Answer: A.) The nitrogen cycle recycles nitrogen through an ecosystem, making it available to all organisms.

Explanation: Nitrogen is an essential nutrient for plants and a significant component of proteins, which all animals need to grow, reproduce and survive. The nitrogen cycle converts nitrogen into compounds that plants and animals can use.

Explanation: Because the first three fish listed feed on coral, their populations will decrease if coral is eliminated because that means there will be less food to go around for the populations to consume. Many will die out. If those fish die, there will be less of them for the sharks to eat, causing the shark population to decrease as well.

B-are made out of organic material that stores the sun energy

C-form where there are frequent earthquakes and volcanic activity

D- are produced high in the mountains where temperatures are low

Answers

Answer:

maybe C i'm so sorry if this is wrong

Explanation:

Organic materials and silt build on top to produce fossil fuels. Heat and pressure transform organic materials into coal, petroleum, or natural gas. Therefore, option (A) is correct.

What are fossil fuels?

An extracted and burnt fossil fuel is a hydrocarbon-containing substance that naturally originated in the Earth's crust from the remnants of extinct plants and animals. Coal, oil, and natural gas are the three primary fossil fuels.

Because certain sedimentary rocks contain trapped fossil fuels, sedimentary rocks and fossil fuels are connected. As organic materials and silt build up on top over time, fossil fuels are created. The organic material undergoes a chemical shift under heat and pressure, turning it into coal, oil, or natural gas.

Jeremy decides to make a model of the Earth. He makes his model by drawing the Earth on a sheet of paper. When he finishes his model, Jeremy notices that the shapes and sizes of the continents are not correct. He also notices that the Earth's surface is cut off at the edges of the drawing. Jeremy decides that he wants his model to be more accurate. How can Jeremy improve his model so that it is more accurate? A. Use a ruler to draw the continents with straight lines. B. Use a thicker piece of paper. C. Draw the Earth on a sphere. D. Draw the Earth smaller on the paper.

Answers

Answer: C. Draw the Earth on a sphere.

Explanation:

Jeremy should draw the Earth like a small sphere that can be drawn completely on the paper and edges will not be left incomplete. The shape and size of the continent can be traced using a map or a stencil. The exact dimension to be drawn is not important but the boundaries should be taken care of and must be accurate.
