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.

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.

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.

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.

A segment of a DNA strand is shown. AGGTCAGG
a. What is the complementary DNA strand?
b. What is the mRNA strand?
c. What amino acids are produced as a result (use the codon chart to help you)
Answer:
b. messenger ribonucleic acid
a. The complementary DNA strand is the sequence that pairs with the given DNA strand. In DNA, adenine (A) pairs with thymine (T), and cytosine (C) pairs with guanine (G). Therefore, the complementary DNA strand of "AGGTCAGG" would be "TCCAGTCC".
b. The mRNA strand is synthesized based on the complementary DNA strand. In mRNA, thymine (T) is replaced by uracil (U). Therefore, the mRNA strand corresponding to the given DNA sequence "AGGTCAGG" would be "UCCAGUCC".
c. To determine the amino acids produced, we need to identify the codons (groups of three nucleotides) in the mRNA strand and refer to a codon chart (also known as a genetic code chart). Here's an example of how the codons in the mRNA strand "UCCAGUCC" can be translated:
UCC (Serine)
AGU (Serine)
CCU (Proline)
Therefore, the resulting amino acid sequence would be Serine-Serine-Proline.

George Box, a famous statistician, once said, "All models are wrong, but some are useful.” What did George Box mean by this statement?
Answer:
The 2nd part, "But some are useful" - simplifications of reality can be quite useful. They can help us explain, predict and understand the universe and all its various components. The idea of this quote is that every single model will be wrong, meaning that it will never represent the exact real behaviour.
George Box, a famous statistician, once said: "All models are wrong, but some are useful" he made an aphorism stating that mathematical models are flawed.
What is an aphorism?Maxim or sentence that, in a few words, explains a rule or principle of moral significance; apothegma, saying. “Short and succinct text, foundation of a fragmentary and unsystematic style in philosophical writing.

Match the following terms and definitions.
1. Glycolysis
2. electron transport chain
3. Krebs cycle
breaks down glucose into pyruvic acid and ATP
picks up hydrogens and produces ATP
produces carbon dioxide, water, and ATP
Answer:
1. Glycolysis - breaks down glucose into pyruvate and ATP.
2. Electron Transport Chain - picks up Hydrogen and produces ATP.
3. Krebs Cycle - produces carbon dioxide, water, and ATP.
Explanation:
1. Glycolysis takes a molecule of glucose and breaks it down into two molecules of glyceraldehyde-3-phosphate(G3P) which ends up as pyruvate producing 4 molecules of ATP ( two from each G3P molecule). However, there is technically a net gain of 2 ATP molecules.
2. Electron Transport Chain - takes Hydrogen from energy-rich molecules, NADHH and FADH2, and produces ATP through a series of steps in the mitochondria.
3. Krebs Cycle - produces carbon dioxide, water, and ATP from pyruvate oxidation which occurs in the mitochondrial matrix (in eukaryotes).
