Answer:
Melanin
Explanation:
Melanin is the protective component of skin that defends us against UV light.
UV light poses big risks to our health, as it can damage DNA. DNA damage can lead to cancers like skin cancer.
Melanin is a pigment in the skin that protects us from UV light. This pigment blocks UV radiation from entering our skin and damaging our DNA.
So, the correct answer is melanin.
Answer:
1. melanin
2. moving away from the equator
3. the impact of UV radiation on folate and Vitamin D levels in human populations
4. A change in one variable produces a change in the other.
5. less predation

Microbial food fermentation is often performed as a preservation method to inhibit the growth of food spoilage microorganisms that may be present in or on the food. The fermentation process often leads to an overall pH decrease of the food to levels below 4. This drop most likely causes many ________ to be inhibited.
Answer:
This question lacks options, options are:
A. Acidophiles B. Alkaliphiles C. Neutrophiles
The correct answer is A. This drop most likely causes many acidophiles to be inhibited.
Explanation:
Microbial fermentation is one of the basic biotechnical processes for the efficient formation of active substances. Fermentation uses fungi, bacteria or cell cultures to transform raw materials into chemicals. Acidophiles is usually bacteria and other very simple organisms that are capable of developing in conditions of too low a pH for most forms of life. Each microorganism has a pH range in which it can grow and a well-defined optimum pH. Depending on the pH, we find acidophiles (1.1 - 5.5), neutrophilic (5.5 - 8.0) and alkaline (8.5 - 11.5) microorganisms, which grow well in acidic, neutral and alkaline pH respectively. Fermentation is carried out to prevent the development of other microorganisms that can alter the quality of the food. Anaerobic digestion is a microbial fermentation in the partial or total absence of oxygen that gives rise to a mixture of gases, in which methane and carbon dioxide are mainly found. Anaerobic microorganisms mainly obtain their energy through the use of fermentation pathways, where organic compounds such as acids and alcohols, among others, basically serve as final electron acceptors. Bacteria, in carrying out these processes, are conditioned by some physical and chemical factors, which enable their proper development, these factors are: loads of organic matter, volatile fatty acids, temperature, alkalinity, nutrients and the presence of N and P , among others.
The digestion of food in the absence of oxygen and release of oxygen is called fermentation.
Microbes that perform the fermentation are usually anaerobic bacteria.
Microbial food fermentation is often performed as a preservation method to inhibit the growth of food spoilage microorganisms that may be present in or on the food. The fermentation process often leads to an overall pH decrease of the food to levels below 4. This drop most likely causes many acidophiles to be inhibited.
Acidophiles or acidophilic organisms are those that thrive under highly acidic conditions.
The lower ph makes the food acidic, due to acidic in nature the bacteria are not able to survive in that conditions.

In which chromosome are sex-linked genes usually found? Explain why these genes are called "sex-linked"
Explanation:
Sex linked is a trait in which a gene is located on a sex chromosome. In humans, the term generally refers to traits that are influenced by genes on the X chromosome. This is because the X chromosome is large and contains many more genes than the smaller Y chromosome. In a sex-linked disease, it is usually males who are affected because they have a single copy of X chromosome that carries the mutation. In females, the effect of the mutation may be masked by the second healthy copy of the X chromosome.

Why dos a single X chromosome that carriers the allele for red-green color blindness cause males to be color blind but doesn’t cause females to be color blind?
Answer:
Because females have two X chromosomes and the red-green color blindness allele has to be in both chromosomes to cause the woman to be color blinded. In the case of males, they only have one X chromosome, so if the allele for red-green color blindness is in the chromosome, the male will be color blinded since there is no other X chromosome with the normal allele as in females.
Explanation:
What determines if a person's sex is the genes X and Y. A sperm carries one of these two genes. When it meets the egg, this one will give the other chromosome, which is always X. So, if the sperm carries the X chromosome, the result, when the egg's fertilized, will be XX, which will give the information to develop a female human. If the sperm carries the Y chromosome, the result will be XY, which is a male.
As females are XX, if the red-green color blindness gene is in one of them, the other chromosome, which does not have this allele, will prevent the woman from being color blinded. We can say that women have a backup copy that prevents color blindness.
In the case of males, as they are XY, there is no extra copy that can prevent them from being red-green color blinded, so when a male has an X chromosome with this allele, they will be color blinded. In the case of women, they will only be carriers of the gene and will be color blinded if the two X chromosomes have the red-green color blindness allele.

Answer:
DDDDDDDDDDDDDDDDDDDDDDDDDD
Answer:
The answer is C.
Explanation:
This is because for A, this statement says nothing about corundum being yellow which means that this doesn’t apply and is incorrect. For B is pretty much the same as A, this statement about corundum doesn’t say anything about it being able to flavor or being flavorful. Lastly for D, the fact that corundum is hard means it would be impractical and probably impossible to use it as pencil lead because, all lead it doing with a pencil is being crushes and ground into the paper as you write.

How does the shape of the red blood allow diffusion to occur efficiently
Answer:
The partial pressure of oxygen determines the affinity of hemoglobin for oxygen. Red blood cells have the shape of a flattened disk, generating a broad surface area for the diffusion of oxygen. Since their only purpose is carrying oxygen throughout the body, they lack many typical cell structures, including a nucleus.
Explanation:
Hope this helps
Answer:
* Because of their viscoelastic characteristic, red blood cells are able to squeeze through very thin capillaries in order to deliver oxygen and remove carbon dioxide. * The biconcave shape of red blood cells helps maximize the overall surface area required for oxygen absorption.

Answer:
Ligase is essential.
Explanation:
The statements that is accurate for DNA replication in your cells but not PCR is that ligase is essential
For better understanding let's explain why ligase is essential
Ligases Enzyme is very essential in DNA replication. it is use for DNA metabolism. They help in catalysis by joining of nicked DNA which is very much needed in in DNA replication. In DNA repair pathways, Ligase is used in the re-synthesis of DNA. It is found that in higher organism, it is of different types..Ligase is not essential in PCR due to the fact that it is not needed.
