Answer:

A student studying primary succesion should focus on Granite rock.

Explanation:

Primary succession includes the presence of rock and the other elements that break down rocks to form soil and other stuffs.

As the student is focusing on the study of the primary succession the main topic would be the granite rock.

The other options relate to the later stage of succession like the Mesquite grassland comes after the primary succession stage.

Granite rock is the intrusive igneous rock that looks like a granular structure.

Answer:

Mutations are errors in genetic information and code that cause physical and functional alterations in living organisms. Some of them may be beneficial, harmful, or not produce significant alterations (neutral).

Explanation:

When categorizing each mutation as beneficial, harmful, or neutral, it's observed that:

A mutation in the HBB gene, which codes for hemoglobin, produces red blood cells that are rigid and sickle-shaped and is harmful.

Sickle cell anemia is caused by the HBB gene mutation, producing crescent-shaped cells, or "YES", which are not functional and very short-lived, causing hemolytic anemia. Deformity in red blood cells can cause blockage of small-caliber arteries, causing other symptoms other symptoms related to the disease.

A mutation in the EYCL3 gene, which helps regulate eye color, produces two different colored eyes, is neutral.

Under normal conditions, EYCL gene determine the color of the eyes. A mutation of this gene can cause the same individual to have a green and blue eye, which is not a serious health problem, but rather aesthetic.

A mutation in the CFTR gene, which codes for a cell transport protein, causes a buildup of a thick mucus that covers the organs, which represents a harmful mutation.

Cystic fibrosis, a disease caused by a mutation in the CFRT gene, produces the excessive thick mucous secretion that lines up the lungs and other organs - liver, pancreas, intestine - that characterizes this condition.This causes a functional alteration of the affected organ. It is also known as mucoviscidosis.

A mutation in the LRP5 gene, which codes for a cell membrane protein, increases bone density, which can be harmful, when it produces symptoms or beneficial.

Increased bone density is called osteopetrosis, and depends on the LRP5 -Low density lipoprotein receptor-related protein 5- gene mutation, that can cause bone pain in childhood and adolescence in just over half of patients, but represents an increase in bone resistance and reduces the risk of fractures.

How did Darwin disprove Lamarck? Explain why Darwin still thought that Lamarck’s idea was very important.

ipn [44]

Darwin’s theory became accepted because it had more evidence that supported it. Lamarck’s theory suggest that all organisms become more complicated over time, and therefore doesn’t account for simple organisms, such as single-cell organisms. We also know through observation that characteristics inherited during an individual’s lifetime do not get passed onto their offspring; for example, if someone pierces their ear, it doesn’t mean that their children will be born with pierced ears. Darwin’s theory became even stronger when, many years after his death, the study of genetics emerged. Genetics ultimately showed that all inherited traits were passed on through genes, which are unaffected by outside world, as Lamarck would predict, and are instead naturally varied, as Darwin predicted. Though Darwin didn’t know what genes were, he could see their effect on natural selection.

Use a Punnett Square of a Bb x Bb cross. B is the factor for brown eyes and bis factor for blue eyes. What color eyes do the par

Georgia [21]

Answer:

The parents would have brown eyes.

Explanation:

Given Bb x Bb, this tells you that both parents have brown eyes and are carriers for a reccessive trait (blue eyes). Remember that the uppercase letters are considered dominant and the lower case letters are considered recessive. In order for the blue eye allele to show, you would need to have the genotype: bb.
