Answer: Mitosis and meiosis are nuclear division processes that occur during cell division.
Mitosis involves the division of body cells, while meiosis involves the division of sex cells.
The division of a cell occurs once in mitosis but twice in meiosis.
Two daughter cells are produced after mitosis and cytoplasmic division, while four daughter cells are produced after meiosis.
Daughter cells resulting from mitosis are diploid, while those resulting from meiosis are haploid.
Daughter cells that are the product of mitosis are genetically identical. Daughter cells produced after meiosis are genetically diverse.
Tetrad formation occurs in meiosis but not mitosis. I hope this helped! Have a good day.

Read the following genetics topics below. Choose a topic and then decide what side you are on. Remember that there is no "right" or "wrong" side. Ethical questions often have many points of view. Research your topic and write a persuasive essay at least 200 words in length and post it in the essay box below.
Topic 1: Should insurance companies have the right to learn the genetic profiles of the people they insure?
Topic 2: Should employers have the right to learn the genetic profiles of the people they hire? Are there special considerations for employees in jobs in which there is a high risk to others, such as airline pilots, doctors, bus drivers?
Topic 3: Should scientists who identify genes and create new genetic engineering techniques have the right to patent their methods for their own profit?
Answer:
1. Although the Genetic Information Nondiscrimination Act of 2008 bars the use of genetic information for health insurance coverage decisions, it does not do so when it comes to life insurance, disability insurance or long-term care insurance. ... And some insurance companies have already started asking.
2. Employers have the right to learn the genetic profiles of the people they hire so that they know the risks that they are taking should there be complications with an employee's health during his/her stay with the company.Jobs that were mentioned in the above statement do not and are not supposed to have special considerations for such situation because these people are holding the lives of their clients in their own hands every time they are out and doing their work.
3.It takes a lot of hard work to make a valuable discovery in genetic engineering, as in any other area. If the people who do the work aren't allowed to patent their discoveries then anyone can take the discovery and use it. The inventor of the new technique won't get any profit for the hard work done. Nobody will work in a field if they don't get paid for it. The new techniques and discoveries will never be made if the inventors don't get paid for their invention. In any event, the payment doesn't go on forever as patents expire in 20 years.

Answer:
Prompt: Should employers have the right to learn the genetic profiles of the people they hire? Are there special considerations for employees in jobs in which there is a high risk to others, such as airline pilots, doctors, bus drivers?
Answer:
My belief is yes and no. In my opinion, the choice really depends on what the job is. Yes, there would be special considerations for high-risk jobs, including first-aid workers, bus drivers, and pilots, to name a few. For example, if someone who was born with narcolepsy probably wouldn't be the best candidate for any type of transportation job. According to Mayo Clinic, "The cause of narcolepsy isn't well understood but may involve genetic factors and abnormal signaling in the brain." On the other hand, employers who are employing people for a camera company may need to know if one of their employees was color-blind for testing purposes, they wouldn't need to know if their employee was born with it or received it from an STD. However, the fact remains, the employers don't have a 'right' to know the genetics of their employees, and most likely, never will. "Genetic Information and the Workplace" says, "Employers should not obtain or disclose genetic information about employees or potential employees under most circumstances.... An employer should be able to disclose genetic information for research and other purposes with the written, informed consent of the individual."

When the availability of resources in an area is limited, organisms may leave a population to move to an area with more resources. What is this movement called? birth rate death rate O emigration immigration
Answer:
Emigration immigration
Explanation:
Emigration means an animal leaves its home because the habitat is no longer ideal for them, and they need to find a more suitable environment. Animals that immigrate or emigrate do not return to the land they left.
When the availability of resources in an area is limited, organisms may leave a population to move to an area with more resources, so the movement is called as Emigration. So, the correct option is C.
What is Emigration?Emigration is defined as the act of leaving one resident's country or place of residence with the intention of settling elsewhere while immigration describes the movement of people from one country to another. A migrant emigrates from his old country, and immigrates to his new country.
Emigration affects the economies of the countries which is involved in both positive and negative ways depending on the current state of the countries' economies. This has an economic impact on the countries involved, including the workforce and consumer spending.
Therefore, the correct option is C.

Describe the impact of a large migration of dolphins into the area. How
would this directly affect other organisms in the ecosystem
Answer:Movement makes dolphins stress which can make your insusceptible framework more vulnerable and the flare-up will spread to different dolphins and conceivably other species.
Large numbers of dolphins migrating from one area to another will have negative consequences for both the new and old ecosystems. The competition in the new ecosystem will increase, and the animals dependent on dolphins in the old ecosystem will suffer.
What is genetic drift?The genetic drift explains how genes move from one ecosystem to another or from one population to another. This genetic drift is caused by migration, mutation, reproduction, and other factors, and it has an impact on the ecosystem.
The large migration of dolphins may be due to unfavorable conditions for living, for food, or for reproduction that led them to move to another place. The migration may be due to the high level of competition in the existing ecosystem. In the ecosystem, some species depend upon the dolphins either for food or for other reasons, and when they migrate, this has a negative impact on those organisms.
If there are abundant resources in the new ecosystem into which they move, there will be no competition; however, if there are fewer resources, competition will emerge, leading to population decline. If they reproduce in a new ecosystem, then new genes will be added here.
Hence, in these different ways, dolphin migration affects the populations of both ecosystems.

determined by...
Answer:
The precise amino acid content, and the sequence of those amino acids, of a specific protein, is determined by the sequence of the bases in the gene that encodes that protein. The chemical properties of the amino acids of proteins determine the biological activity of the protein.
Explanation:
The proteins are formed of amino acids that are in a specific sequence, and is determined by the sequence of the bases in the genes.
The chemistry of amino acids:Both as the building blocks of proteins and as intermediates in metabolism, amino acids play an essential role. In a specific protein, the exact content of amino acids, and the amino acid sequence are predicted by the sequence of the bases in the gene that encrypts that protein.
The biological activity of the protein is determined by the chemical properties of the amino acids.

Answer: c) Transcription occurs in the nucleus while translation occurs in the cytoplasm in eukaryotes, D) Transcription produces an mRNA molecule while translation converts the code from mRNA into a protein, E) Transcription require RNA polymerase while translation requires ribosomes to build their end product molecules
Explanation:
The central dogma of molecular biology involves two cellular processes, transcription and translation. The process occurs at different sites in the eukaryotic cells.
The correct options are:
Option C: Transcription occurs in the nucleus while translation occurs in the cytoplasm in eukaryotes
Option D: Transcription produces an mRNA molecule while translation converts the code from mRNA into a protein
Option E: Transcription requires RNA polymerase while translation requires ribosomes to build their end product molecules
The explanation for transcription and translation can be given as:
1. Transcription takes place in the nucleus, whereas translation occurs in the cytoplasm of a eukaryotic cell.
2. Transcription is the process of decoding the message from DNA to mRNA. Translation occurs after transcription, in which messages coded into mRNA are converted into polypeptides.
3. The enzymes are essential for catalyzing processes like transcription and translation. The transcription is carried out by RNA polymerase, whereas translation requires ribosomes to build products.
Thus, translation and transcription are the two parts of the central dogma.
