Answer:
The correct answer is D. maintain membrane fluidity through its disruption of fatty acid packing.
Explanation:
Cholesterol is a steroid lipid and is a constituent of biological membranes. It regulates the fluidity of the membrane (so, option C is not correct). Since cell membranes are composed of another type of lipids, the phospholipids, which form a bilayer, cholesterol distributes between the phospholipid tails and avoids these molecules pack each other forming rigid clusters. Thus, the option which better explains the effect is D. maintain membrane fluidity through its disruption of fatty acid packing.

If there's a higher concentration of solutes outside of the cell what will happen
Answer:
If there's a higher concentration of solutes outside of the cell (the solution is known as hypotonic solution) then the cell will swell up as the solutes will flow into the water through the process of osmosis. The cell may also swell up & burst (if it's an animal cell).

Why are people who go to strip clubs generally NOT considered to be voyeurs?
Group of answer choices
The nudity of the performers is not complete.
There is no sense that people who go there are doing something frowned on by society.
The performers are consenting to being seen by the audience.
The performers are exhibitionists and it's impossible for someone to simultaneously be an exhibitionist and a voyeur.
Answer:
The performers are consenting to being seen by the audience.
Explanation:
A voyeurist experiences pleasure from observing someone else having sexual relations, undressing, or performing any sexual activity. The voyeurist does not have the person's consent to watch, and they find ways to do it from a distance or with discrepancy. Part of their pleasure is from observing the person without consent, and another part is from observing the person engage in sexual activities. They do not desire to be in a sexual relationship with the observed person; they want to watch.
People who go to strip clubs do not observe from afar and hiding from the performer. They have the consent of the performers, which is the opposite of what attracts a voyeurist.
A red flowered plant (RR) is crossed with a white flowered plant (WW) and produces plants with pink flowers (RW). If two pink flowered plants are crossed, what color offspring could be produced
Answer:
It would be 100 % pink.
Explanation:
Pink and Pink make Pink. Just as Red and White make Pink.
Due to incomplete dominance, when two pink flowered plants are crossed, the color of offspring could be 1Red: 2Pink :1White.
What is incomplete dominance?In some cases it happens that a certain characteristics does not match with either of their parents, rather it shows new traits.For example: snapdragon.When parent generation of red flowered plant (RR) is crossed with a white flowered plant (WW), F1 produces plants with pink flowers (RW). it does not resembles either of their parents.And when F1 was self pollinated: RW x RW, it produces 1 RR: 2RW: 1WW.Hence, the offspring will be 1 Red flowered plant: 2 Pink flowered plant :1 White flowered plant.

A model for gene expression and regulation is shown here. Not all genes are expressed at all time, and a study of the proteins within
a cell indicates that not all of the gene products are present within a cell. Analyze the model and evaluate which statement(s) below
are correct based on the gene expression. Select ALL that apply.
A)
Inactive DNA prevents the gene expression at the earliest stage.
B)
Removal of the mRNA before it is translated can regulate the gene
expression
Regulation of the mRNA is the most efficient mechanism for reducing gene
expression.
D)
DNA, once transcribed, will produce multiple protein products with very
little regulation in the process.
The targeted destruction of the protein can reduce the overall expression
of the gene at a later stage in the process.
E)

Quick question. I am trying to cite my sources for my biology research project and the website that I used is a rare disease informational center with different topics. For example there is a summary section, a symptoms section etc.... I need to cite my sources however each section has a different publication date because they don’t update the entire article at once. I am currently trying to use an in text citation for the summary because I used a quote from the summary so do I just use the summary publication? But I did use other sections of this website for other parts of my essay so when it comes time to making my bibliography what do I do
Answer:
For your bibliography, you need to put the website but also put the sections you got your examples from. Also, don't forget to put the person who published the summary down as well. Hope this helped

Villi and microvilli help to absorb nutrients in your small intestine.
True
False
Answer:
True
Explanation:
Microvilli: The cells on the villi are packed full of tiny hairlike structures called microvilli. This helps increase the surface of each individual cell, meaning that each cell can absorb more nutrients.
Answer: TRUE
Explanation: Villi are folds on the small intestine lining that increase the surface area to facilitate the absorption of nutrients. Absorptive cells that line the small intestine have microvilli, small projections that increase surface area and aid in the absorption of food.
So, the correct option is 'True'.

Explanation:
What volume will 1.2 mol of N, occupy at 17°C
and 2.0 atm?
Answer:
14.284
Explanation:
Know parameters from the problem are: the amount of the substance/ gas molecule is 1.20 mol, the Temperature of the gas is 17 Celsius degrees (i.e. 290.15 K [17 Celsius degrees plus 273.15 K]), the pressure exerted on the container by the gas is 2.0 atm.
The unknown ( what you are asked to find) is the volume that the gas would occupy in its container under those conditions above; V=?.
We use the ideal gas equation here; PV=nRT. R in this equation is called the molar gas constant or Ideal has constant. There are many values for R given different circumstances. For the condition of this problem, R's value is 0.08205 L atm/mol K.
Make V the mathematical subject of the equation PV=nRT.
V=(nRT)/P
V=(1.20 mol x 0.08205 L atm per mol per K x 290.15 K)/ 2.0 arm
V= (28.568169 L atm mol per mol per K)/ 2.0 atm
V= 14.284 [(L atm mol K)/(atm mol K) atm mol K is in the numerator and the denominator would be canceled. Leaving only L.
Therefore, V= 14.284 L of N

Suppose you want to design and build a house. How would you communicate your design plans with the construction crew that would work on the house
Answer:
Provide designs in the written form.
Explanation:
You will communicate with your design plans with the construction crew through designs or layout on the paper which they follow during building of the house. The best way to tell about the designs of your house is to made the design on the paper correctly. This design in the written form helps and guide the workers to build the house just like you wanted to be. Orally telling about the designs sometimes causes mistakes in the building of house so written form is the best way.

12. Individuals with Type O blood are able to produce both Anti-A and Anti-B antibodies, while individuals with Type AB blood produce neither of these antibodies. Explain why this is the case. How does this relate to the idea that people with Type AB blood are often referred to as universal recipients for transfusions
Answer: Blood group O individuals are able to produce Anti- A and Anti- B and are often referred to as UNIVERSAL DONORS, while blood group AB individuals produces none and are often referred to as UNIVERSAL RECIPIENTS
Explanation:
Two antigens, type A and type B, occur on the surfaces of the red blood cells in a large proportion of human beings. These antigens are referred to as agglutinogens because they often cause blood cell agglutination during blood transfusion. Because of the way these antigens are inherited, people may have neither of them on their cells , they may have one or they may have both simultaneously.
When type A antigen and type B antigen is not present in an individuals reb blood cell as seen in blood group O, antibodies known as Anti-A and Anti- B develops in the plasma. This is because small amounts of type A and type B antigens enter the body through food, bacteria and other ways and they initiate the development of anti A and Anti- B antibodies in their plasma.
Furthermore, individuals with blood type AB has antigen A and B on their red blood cells and therefore do not develop antibodies A and B in their plasma. This makes them universal recipient as their blood do not discriminate any ABO blood group during blood transfusion.
