Which statement below regarding membrane structure and membrane transport is true? a. Increasing the proportion of unsaturated f

atty acids of membrane phospholipids would be most likely to occur as environmental temperatures become warmer. B. Cyclization of membrane phospholipid fatty acids (like cyclopropane) would confer more rigid, straighter hydrocarbon chains. C. Membrane lipids of hyperthermophilic archaebacteria are of the ester-linked fatty acid type also found in non-archae bacteria and eukaryote membranes, respectively. D. Cell wall-containing bacteria and archaea tend to possess a slightly hypotonic interior to create a positive turgor pressure thereby helping it to maintain cell shape and form. E. Abc transporters and group translocation use a transport mechanism that moves molecules via facilitated diffusion.

The statement regarding membrane structure and membrane transport which is true is: B. Cyclization of membrane phospholipid fatty acids (like cyclopropane) would confer more rigid, straighter hydrocarbon chains.

<h3>What is a membrane structure?</h3>

A membrane structure can be defined as a thin bilayer (double sheet) of an internal cell compartment which forms the outer boundary in living cells that are found in the body of a living organisms.

<h3>What is membrane transport?</h3>

A membrane transport can be defined as collection of mechanisms that are saddled with the responsibility of regulating the movement of solutes such as ions and tiny particles across or through biological membranes and lipid bilayers containing proteins embedded in them.

Based on scientific studies, the similarity between membrane structure and membrane transport is that cyclization of membrane phospholipid fatty acids such as cyclopropane would confer more rigid, straighter hydrocarbon chains.

Satya, nina, and iana each have a 3/4 chance of going to café georgia for an afternoon coffee at 1:00pm. Bohan will only go to c
larisa86 [58]

Using the binomial distribution, it is found that there is a 0.9844 = 98.44% probability that bohan goes to café georgia for a coffee today.

For each friend, there are only two possible outcomes, either they go to the cafe, or they do not. The probability of a friend going to the cafe is independent of any other friend, hence, the binomial distribution is used to solve this question.

<h3>What is the binomial distribution formula?</h3>

The formula is:

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

C_{n,x} = \frac{n!}{x!(n-x)!}

The parameters are:

  • x is the number of successes.
  • n is the number of trials.
  • p is the probability of a success on a single trial.

In this problem:

  • There are 3 friends, hence n = 3.
  • They all go to the cafe with a 3/4 probability, hence p = 3/4 = 0.75.

The probability at least one goes is:

P(X \geq 1) = 1 - P(X = 0)

In which:

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

P(X = 0) = C_{3,0}.(0.75)^{0}.(0.25)^{3} = 0.0156

Then:

P(X \geq 1) = 1 - P(X = 0) = 1 - 0.0156 = 0.9844

0.9844 = 98.44% probability that bohan goes to café georgia for a coffee today.

A girl runs 40 m, west, 50 m south, 60 m, east. what is his net displacement?
balandron [24]

The displacement of the girl which the relative change in her position from her starting point. Therefore, the shortest distance between her initial and final position is 58.85 m North - West

From the sketch of the girls movement attached below, the displacement of the girl can be calculated thus :

Using Pythagoras :

Displacement, d = √(50² + 20²)

d = √(2500 + 400)

d = √2900

d = 53.851

Therefore, the displacement of the girl, which is the shortest distance between her current position and starting position is 53.85 meters NW.
