Cytochrome C is a protein that functions in cellular respiration as part of the electron transport chain. It is frequently used to determine evolutionary relationships between different organisms because it is highly conserved (only differs slightly) between different organisms. A student researching evolutionary relationships between different organisms came across the following information about the differences between cytochrome C proteins in different organisms when compared to humans. Number of different amino acids compared to humansChimpanzee0Rhesus Monkey1Cow10Yeast42 The student plans to use an antibody to the human cytochrome C protein in an ELISA test on cytochrome C samples from these four organisms. What should she use as a positive control

Answers

Answer:

Human cytochrome C

Explanation:

The enzyme-linked immunosorbent assay (ELISA) is a technique widely used to detect and measure antibodies and antigens in biological samples. This technique can be used to diagnose different diseases by detecting antigens that bind to antibodies. The ELISA test consists of a plate with a capture antibody against the antigen of interest coating the plate. Subsequently, the target antigen is detected by adding a detection antibody labeled with an enzyme (e.g., alkaline phosphatase) that binds to this antigen. Finally, a particular substrate (e.g. ABTS) is added to the plate and the subsequent reaction converts it into a colored product which can be easily detected using microplate readers. In this case, the positive control will be human cytochrome C which will bind to specific antigens in order to evidence the presence of this molecule in the sample.

How does evolution work to create the diversity of life on Earth?

Answers

Evolution and diversity result from the interactions between organisms and their environments and the consequences of these interactions over long periods of time. Organisms continually adapt to their environments, and the diversity of environments that exists promotes a diversity of organisms adapted to them.

How does ovolution lead to both biodiversity and commonalities among
life?

Answers

Answer:

Evolution leads to biodiversity by changing the genetic code of organisms. When evolution leads to biodiversoty its called natural selection. It slowly decreases the popluation of organisms that are less adapted to survive in the world, and increas the population of more strong and adaptable organisms.

For example if there is a pink bird and a white bird, the white bird's population will increase due to its adaptation of camoflauge, and the pink bird will die out because it will be spotted by predators easily. Therefore the species of the white bird will become more common

Most cells in our body have two versions of each chromosome (Body cells). These cells are called diploid. We grow and replace these cells with identical cells through a cell division called mitosis.

For sexual reproduction, we need to make cells that have only one version of each chromosome (sex cells). These cells are called haploid. These unique cells are made through a cell division called meiosis.  

Explanation:

haploid = 1

diploid= 2 // "di"=2

Why do the temperatures change over the months?
O A. Because the Moon is tilted on its axis, it reflects more sunlight on Earth during different times of Earth's yearly orbit.
B. Because the Sun is tilted on its axis, parts of Earth get more sunlight during different times of Earth's yearly orbit.
O C. Because Earth is tilted on its axis, the stars reflect more light during different times of the Earth's yearly orbit.
D. Because Earth is tilted on its axis, parts of Earth get more hours of sunlight during different times of Earth's yearly orbit.

Answers

Answer:

Answer

Explanation:

B because the more the sun is titled the more heat=different season.

Because Earth is tilted on its axis, parts of Earth get more hours of sunlight during different times of Earth's yearly orbit. As Earth orbits around the Sun, its axis is tilted at an angle of about 23.5 degrees. Hence the correct option is D.

Why do the temperatures change over the months?

The temperatures change over the months primarily because of Earth's axial tilt. As the Earth rotates around the sun, the angle at which sunlight hits different parts of the Earth changes.

This is because the Earth's axis is tilted about 23.5 degrees relative to its orbit around the sun. When a particular hemisphere is tilted toward the sun, it receives more direct sunlight, resulting in warmer temperatures.

Conversely, when that hemisphere is tilted away from the sun, it receives less direct sunlight, resulting in cooler temperatures. This cycle repeats itself annually, causing changes in temperatures over the months.

Hence the correct option is D.
