Answer:
38 chromosomes are in the red foxes DIPLOID skin cells
Explanation:
There are two principal types of cells in the organism:
Diploid cells (2n) Somatic diploid cells (2n) reproduce by the process of mitosis and produce two diploid cells.Germ diploid reproductive cells (2n) also reproduce by mitosis and produce two diploid cells. But can also reproduce by the process of meiosis, suffering a reduction in the number of chromosomes and producing four haploid cells (n). Haploid cells (n)Gametes are the product of germ cell division by meiosis, and they have only one set of chromosomes, n (19 in this example). Their destiny is to merge in the process of fecundation, during which a new diploid cell called the zygote emerges through fertilization. The zygote is a complete diploid cell that suffers successive mitosis and forms a new organism (a new fox in this case).
- So, through meiosis, the diploid germ cell (2n) produces four haploid cells (n) that are the gametes.
- Through fecundation or fertilization, two gametes (n) merge and produce a diploid cell (2n) that is the zygote.
If the red fox gamete has 19 chromosomes (haploid number n, the single set of chromosomes), it must merge with another gamete (coming from the other parent) with 19 chromosomes to form the zygote. The zygote is a diploid cell. The zygote will suffer many mitosis divisions to become a new fox.
To know the number of chromosomes in a skin cell, we need to duplicate the number of chromosomes in the gamete (19).
N = 19 = Haploid number2N = 2 x 19 = 38 = Diploid numberWhat a water pollution

how do variations lead to adaptations?
Answer:
Favorable variations may allow an organism to be better adapted to its environment and survive to reproduce. Beneficial traits are favored in a population so that they may become better represented. Changes in the genetic makeup of a species may result in a new species; this is biological evolution.

A. concentrates
B. dry roughage
C. green roughage
D. silage
E. dry matter
Answer:
D.
Explanation:
Answer:
Green Roughhage
Explanation:
Roughages are high in fiber and low in digestible nutrients. There are three kinds of roughages: dry, green, and silage. Dry roughage such as hay has a low moisture content. Grasses in pastures and root vegetables (like turnips) are called green roughage and have a high moisture content. The fermentation of green plants results in the formation of silage.

are in a specific sequence that is
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.
Thus, the specific sequence of the proteins is determined by the sequence of the bases in the genes.

Transcription requires an RNA template while translation uses a DNA
template.
Transcription is performed by prokaryotes while translation' is performed by
eukaryotes.
Transcription occurs in the nucleus while translation occurs in the
cytoplasm in eukaryotes.
Transcription produces an mRNA molecule while translation converts the
code from mRNA into a protein
Transcription require RNA polymerase while translation requires ribosomes
to build their end product molecules.
D)
E)
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.

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.
Explanation:
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."
