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.

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.

2. Optic Nerve

3. Macula

4. Fovea

5. Retina

6. Lens

7. Pupil

8. Cornea

9. Iris

Explanation:

I hope this helps!

These are Vitreous gel, Optic Nerve, Macula, Fovea, Retina, Lens, Pupil, Cornea, Iris respectively.

Three coats enclose the optically clear aqueous humour, lens, and vitreous body in the eye.

The cornea and sclera form the outermost coat; the choroid, ciliary body, and iris form the middle coat, which contains the main blood supply to the eye and extends from the back to the front.

The eye functions as a sensory organ. It collects light from our surroundings and converts it into nerve impulses. The optic nerve sends these signals to the brain, which creates an image and thus provides sight.

Thus, as per the labeling number, Vitreous gel, Optic Nerve, Macula, Fovea, Retina, Lens, Pupil, Cornea, Iris respectively are the parts of eye.

Answer: this is adaptation, but not in the way suggested in the question.

Explanation:

The question is suggesting that the 1% or so of turtle hatchlings that make it to maturity are the result of a variation that gives a selective advantage. This is not so. The only thing being selected for is sheer luck. The underlying adaptation is that all eggs hatch within a short period, so that predators are overwhelmed by numbers and some offspring by chance make it to the water, still dangerous, but less so than the sand. After the hatchlings reach the sea chance will still be a factor, but it is at this stage that natural selection may operate on advantageous variations.

There are two reproductive strategies, common to plants as well as animals. Turtles represent one of those strategies, which is to invest resources to produce large numbers of immediately self-sufficient offspring so that at least some will survive. The other strategy is to produce one or few offspring and invest resources in protecting and feeding it or them until self-sufficient and capable of surviving to maturity.

These are adaptations which are selected for because they confer advantage for the species concerned. One or the other may be the better solution depending on the species. Mammals, for example, invest in the latter strategy.

una de las proteinas positivas ees la leche.

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.

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."

Answer:

A homo-zygous dominant genotype and a heterozygous genotype

Explanation:

A homo-zygous dominant genotype refers to a genotype that contains two copies of the dominant gene variant, i.e., two dominant alleles at its locus, thereby individuals carrying this genotype will show a dominant phenotype. Moreover, a heterozygous genotype is a genotype that contains both dominant and recessive alleles at its locus. In a heterozygous genotype, the dominant allele is always expressed and masks the recessive allele, thereby showing a dominant phenotype.
