What is the plasma (cell) membrane? What is its main function?

Answers

The plasma membrane, also called the cell membrane, is the membrane found in all cells that separates the interior of the cell from the outside environment.

The plasma membrane, or the cell membrane, provides protection for a cell. It also provides a fixed environment inside the cell. And that membrane has several different functions. One is to transport nutrients into the cell and also to transport toxic substances out of the cell.

The plasma membrane is the outermost layer of a cell. It’s mainly responsible to act as a barrier to maintain proteins within the cell

pleiotropy

Answers

Answer:

D.) pleiotropy

Explanation: Just took the quiz.

Pleiotropy arises when one gene affects two or more seemingly unrelated phenotypes. A pleiotropic gene expresses many phenotypes. Therefore, option (D) is correct.

What is Pleiotropy?

When one gene influences two or more phenotypic qualities that do not appear to be related to one another, this phenomenon is known as pleiotropy. A gene is said to be pleiotropic if it can exhibit many phenotypic expressions in a single organism.

Phenylketonuria is a condition that serves as a straightforward illustration of a pleiotropy. A slow metabolism of the amino acid phenylalanine in the cells of the body is the root cause of this hereditary condition, which causes phenylketonuria.

What do you think is the more ethical and feasible approach to wildlife preservation: change human behavior to limit human impact, or create sanctuaries to preserve some of the threatened animals’ population? Why?

Answers

Answer:

I think we need to do both, but I'll let you decide which you think sounds better for you personally (personally I think sanctuaries are often more effective).

Explanation:

Behavior changes It is not really ethical to continue to have a negative impact when changing our behavior can help, however, this may not be ideal as explained below

Sanctuaries It is often more feasible to create preservation sanctuaries because 1) it is hard to get everyone to change enough habits in order to create large-scale change and 2) some species require more immediate action to save, whereas changing human behavior may not be enough and/or at the right pace to preserve and expand the populations of endangered populations

Depending on the main threat to a specific population, the approach will obviously be different.

how many calories are in an average trick-or-treaters halloween stash?

Answers

The number of calories on a Halloween stash depends on the type of candies and the number of units of each. If the stash contains 5 units of each of these candies: chocolate bars, taffies, lollypops, and candy corn the total number of calories is 1,650.

Calories are the most common unit used to define the energy a specific food gives to your body. For example, an apple has 52 calories, while a banana has 89 calories.

Considering this, in a Halloween stash the calories depend on two factors:

The types of candies or productsThe units of each one

Let's suppose there are 5 units of each of the following candies:

Chocolate barsTaffiesLollypopsCandy corn

Let's now calculate the calories

Chocolate bars = 220 calories x 5 units =  1,100 caloriesTaffies = 20 calories x 5 units = 100 caloriesLollypops = 83 calories x 5 units = 415 caloriesCandy corn = 7 calories x 5 = 35 calories

Add all the previous results:

1,100 + 100 + 415 + 35 = 1,650 calories in total

If an experiment was being conducted using an enzyme that was very sensitive to changes in pH (which could result in denaturation), what should be added to the experiment to prevent the enzyme from denaturing?
A. a buffering solution
B. extra substrate
C. an acid
D. a base

Answers

Answer:

maybe the answer is C..sorry if i wrong

If an experiment was being conducted using an enzyme that was very sensitive to changes in pH, a buffering solution must be added in order to prevent the enzyme from denaturing. Thus, the correct option for this question is A.

What is the denaturation of an enzyme?

The denaturation of an enzyme may be defined as a process through which a molecular structure of an enzyme gets deviate from its original state due to exposure to high temperature, pH sensitivity, etc.

The function of a buffering solution is to stabilize the pH of the given solution. It helps the other component of the solution to resist in response to pH change. A Buffer solution is capable to neutralize the effect of the small amount of acid or base.

Therefore, a buffering solution must be added in order to prevent the enzyme from denaturation. Thus, the correct option for this question is A.
