explain why antibiotics such as penicillin, kill bacteria and not viruses

Answers

Answer 1

Answer:

Antibiotics cannot kill virus.

Explanation:

Viruses are different from bacteria.They have different ways of survival and reproduction.Viruses have a protective protein coat instead of cell wall.But many Antibiotics including penicillin work by attacking cell wall.

Thus bacteria can be attacked by antibiotics but viruses cannot.

Answer 2

Antibiotics cannot kill viruses because viruses have different structures and replicate in a different way than bacteria.

Why? It is not A or D for many reasons but cell differentiation is used for very specific functions as cell determination is used for different embryonic functions. Based on the diagram I seems to me that it is not very specific so that’s why I think it’s B

What are the 3 structures that leave from the kidney?​

Answers

Answer:

an outer cortex, a medulla in the middle, and the renal pelvis in the region called the hilum of the kidney.

Explanation:

Internally, the kidney has three regions—an outer cortex, a medulla in the middle, and the renal pelvis in the region called the hilum of the kidney. The hilum is the concave part of the bean-shape where blood vessels and nerves enter and exit the kidney; it is also the point of exit for the ureters.

A. 100
B. 75
C. 50
D. 25
E. 0

Answers

Answer

75% chance

Explanation:

The dominant and recessive are the terms used to explain the phenotypic traits and genetic makeup of an organism. The cross between a heterozygous species will result in a 75% chance of the species expressing a dominant phenotype.

The correct answer is:

Option B. 75%

The heterozygous condition refers to the one dominant and one recessive allele, whereas purebred is the condition in which both alleles are either recessive or dominant.

The dominant alleles are always expressed in purebred and heterozygous conditions.

The recessive alleles are expressed in purebred conditions only.

In the given attachment, consider the cross between round shaped-seeds in heterozygous conditions.

Thus, the chance of progeny will have round-shaped seeds is 75%.

The processes of transcription and translation are critical pieces of gene expression to produce proteins in all living cells on earth.
Which statements correctly differentiate transcription and translation? More than one statement may apply.
es -)
A)
B)
09
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)

Answers

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.

Is it varration , overpopulation or adaption On average, sea turtles lay about 110 eggs in a clutch. However, only a fraction of the baby turtles make it to the ocean. Then, an even smaller number have offspring of their own.

Answers

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.

In one or more paragraphs respond to the question below. Do you think that teaching evolution should be allowed in public schools? Explain your opinion

Answers

Hi there, this is opinion based but here is my take (you can change and add to it if you want, just copy and paste my answer)

Teaching evolution should be allowed in public schools. Yes, many have issues with the fact that evolution would go against many religious beliefs, but it is scientifically proven, and so it should be assessable to everyone. If you were to go work in a place and they ask you what you know about evolution, wouldn’t it be absurd to say “I don’t know because i was never allowed to learn about that subject.” It is completely preposterous to deprive yourself of the reality of what is going on in the world.

Ok that was it. Btw i am indeed a religious person and i still think evolution should be taught, if you were wondering.

What are two genotypes that could produce a dominant phenotype?

Answers

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.

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?

Answers

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."
