The fatty acids in the tail of a phospholipid molecule are?

Answers

It consist of two fatty acids, a glycerol molecule and a phosphate group that is controlled by an alcohol. Usually the phosphate group is the negatively charged polar head, making it hydrophilic. The fatty acids are chains of uncharged and non polar tails which makes these hydrophobic.

Answer:

Nonpolar and Hyrdrophobic

Which one of the following reactions occurs in the cristae of the mitochondria? A. The citric acid cycle B. The electron transport chain C. The prep reaction

Answers

Answer: B - The electron transport chain

The electron transport chain is a part of the cristae of the mitochondria and is vital for cellular respiration. The citric acid cycle takes place in the inner membrane of the mitochondria. The prep reaction does not occur in the mitochondria, it occurs in the cytoplasm of a living cell.

What is the main method of heat transfer from the core to the crust of Earth?A) conduction
B) convection
C) insulation
Eliminate
D) radiation

Answers

The answer to this question is letter B. Convection.

>Mantle's convection is thought to make up about eighty percent of the internal heat flow to the surface, while the remainder originates in the crust.
>The main means of heat transfer is convection. This process requires that the substance can behave like a "fluid", and the earth's mantle does.

The answer is

B

Convection currents raise the less dense hot material from the center to the cool crust and material from the cool (dense) crust settles down to the core to be heated again.

Explanation:

1. An advantage of light microscopes compared to electron microscopes is that light microscopes A)allow you to view living cells, while electron microscopes do not. B)allow you to view the surface of cells in greater detail than electron microscopes. C)have a higher magnification capability because they use natural light. D)have a greater resolution available because they use white light. 2. To study the details of protein molecules on the surface of a cell, a biologist would likely use a A) compound light microscope. B) dissecting microscope. C) scanning electron microscope. D) transmission electron microscope. 3. What would be the magnification of a specimen viewed with a compound light microscope that has an objective power of 40x and an ocular lens power of 10x? (2 points) 40x 50x 400x 500x

Answers

Answer:

1. The correct answer would be A) allow you to view living cells, while electron microscopes do not.

There are many advantages of light microscope over electron microscope such as:

It is easy to use as compared to the electron microscope.
It enables us to view both alive as well as dead specimen whereas electron microscope can be used to view dead specimen only.
Light microscopes are much cheaper and have much lower maintenance cost as compared to the electron microscope.

2. The correct answer would be C) scanning electron microscope

Scanning electron microscope or SEM is a type of electron microscope which is used to observe surface topography and composition of the specimen. It can achieve resolution of up to 1 nanometer.

3. The correct answer would be 400x

The total magnification of the microscope can be calculated by multiplying the powers of the objective lens and that of the eye lens.

Thus, the magnification of the specimen would be 40*10 = 400x.

1. The correct answer is A) allow you to view living cells, while electron microscopes do not. Light microscopes use visible light to illuminate specimens, which is less damaging to living cells compared to the electron beams used in electron microscopes.

The electron microscope

2. The correct answer is C) scanning electron microscope. Scanning electron microscopes (SEMs) are commonly used to study the details of protein molecules on the surface of cells. SEMs provide high-resolution images of the surface topography by scanning the specimen with a focused beam of electrons.

3. To calculate the total magnification of a compound light microscope, you multiply the magnification of the objective lens by the magnification of the ocular lens. In this case, the objective power is 40x, and the ocular lens power is 10x. Therefore, the magnification of the specimen viewed with this compound light microscope would be 40x * 10x = 400x. So, the correct answer is C) 400x.
