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.

The chart given describes the process of evolution from early life forms.

Earliest life-forms were Prokaryotes which include archeobacteria and eubacteria.

Archeobacteria includes cyanobacteria which generated oxygen that formed ozone which enabled life on land.

Prokaryotes left fossils that were formed 2.5 billion years ago.

Prokaryotes became chloroplasts and mitochondria that originated through endosymbiosis.

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?

Answers

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"

Answers

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.

Describe in your own words, human ovulation and the menstrual cycle

Answers

Answer:

Ovulation occurs around 14 days before your period. If your average menstrual cycle is 28 days, you ovulation is on most likely on day 14. If the usual menstrual cycle is 35 days ovulation most likely happens day 21.

Explanation:

hope this helped!

The menstrual cycle is a (generally) 28 day cycle in which the fertilized egg is released through the ovaries and out the vulva. When an egg isn’t fertilized by a sperm, the walls of the uterus shed giving females a period. Bleeding is generally around 7 days but varies from individual to individual. Ovulation happens when the egg is being released and is ready to be fertilized, making it a good time to try and conceive a child.

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.

Answers

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.
