Answer:
Explanation:
The mucous membrane lining provides lubrication which allows the vagina to act as a sexual organ. Without this membrane lining, the skin would get dry which would create friction when involved in intercourse. This friction can cause damage such as membrane tearing and even bleeding or burns. The anus does not have the mucous membrane lining like the vagina does which affects it from being an effective sexual organ like the vagina.

What structure is found in viruses but not in cells?
The structure is found in viruses but not in cells is - Capsid, made up of protein around the virus but not present in cells.
Viruses are considered non-living as these are molecules neither these are cells nor they are made up of cells. They do not have any traits of the living organism.
They have genetic material which is RNA.The genetic material of Viruses is enclosed in the protein structure or coat called Capsid.they can not reproduce on their own.Cells have various cell organelles and cell structures such as cell walls, mitochondria, cell membrane, genetic material, and many more but lack protein coat or capsid around them but are made up of cells or a single cell.
Thus, the correct answer is - protein capsid.

A scientist is developing a potential treatment for cancer. She grows cells in hundreds of petri dishes and exposes the dishes to environments that are known to cause cancer. After exposure, the scientist determines that some of the petri dishes have cancer cells.What factor do all the petri dishes that contain cancer cells have in common?
Answer:
they are normal mutations you can never have a cure to cancer you would have to throw a lot of your DNA and genes away to have a less chance of dying but we could slow or kill cancer but no way to prevent it from happning as it happens everyday to you but those cells have a higher chance to become cancer becuase of those thing that help cells to become cancer.

Often in laboratory experiments you will want to amplify regions of the genome from several different preparations of gDNA. To do this, a mastermix will be created with all the common reagents to ensure easier pipetting, proper mixing, and controlling for variations in pipetting. Create a mastermix for running 8 identical reactions, including one negative control, each with different gDNA templates (7 total gDNA templates).
Answer:
Mastermix in PCR helps in providing faster and easier setup with pipetting, proper mixing, reduction in contamination and controlling fir variation in pipeting or tube to tube variability. Contents of PCR master mix for the desired reaction are as follows:
dNTPsPrimersthermostable DNA polymerasecofactor (MgCl2)Template DNA (for 7 samples)PCR-grade waterThe only difference in negative control for the PCR master mix is template or the different primer rest the components are the same in the master mix.

If a de-shelled egg gains weight after being soaked in sucrose solution, what term best describes this solution?
Answer:
The correct answer would be - hypotonic solution.
Explanation:
The egg cell contains more solute than the sucrose solution which makes the sucrose solution a hypotonic or low solute solution. Hypotonic solution is a solution that has low concentration of the solutes than the another solution. This tye of case leads to the movement of the water to, move in the area of high concentration of solutes.
In this case the water will move in to the egg and swell the egg due to the diffusion of water through semipermeable membrane from low solute area to high solute area.
Explain why emerging efforts are focused on reducing health risks from exposure to chemicals rather than completely
eliminating those risks.
Answer:
Working with all chemicals carries some level of health risk, and modern society is dependent upon thousands of chemicals to maintain our standard of living. Therefore it is not reasonable to eliminate all chemical related health risks because that would require we stop using chemicals like cleaning supplies, gasoline, and fertilizers. The more practical approach is to minimize and manage the health risks associated with chemical exposure.

Which of the following base pairs would be found in a cell
The base pair cytosine and guanine is found in the cell. The correct option is D.
What are base pairs?A base pair is a primary component of double-stranded nucleic acids that comprises two nucleobases that are hydrogen-bonded to one another.
They are the foundations of the DNA double helix and make a contribution to both DNA and RNA's folded structure.
Purines and pyrimidines are nitrogen bases that form hydrogen bonds between DNA strands.
Predicated by Chargaff's Rule, they associate together via complementary pairing A::T and G::C. The purines in DNA are the same as those in RNA: adenine and guanine.
The 2 significant pyrimidine bases in DNA are cytosine and thymine, which base pair with guanine and adenine. Uracil supplants thymine and base pairs to adenine in RNA.
Thus, the correct option is D.

The graphs show the reaction rate for an enzyme across a range of temperatures and pH. Based on these data, this enzyme functions best at what temperature and pH? *
The graph is attacged and the options is as follows:
Temperature of 27oC and a pH of 4
Temperature of 37oC and a pH of 6
Temperature of 40oC and a pH of 8
Temperature of 50oC and a pH of 10
Answer:
The correct answer would be - temperature of 37oC and a pH of 6
Explanation:
The graph 1 shows the relation between the rate of reaction for an enzyme and the temperature of reaction is been represented. In this graph the rate of eaction is highest (point from the slope starts decreasing) at the So, by the options and graph the temperature 37°C(Below 40°C) rate of reaction is maximum.
Similarly, in other graph rate of reaction and and pH has been represented in which rate of reaction is maximum at pH 6. after 6 pH the rate of reaction started decreasing.
