Should we clone animals that are going or have gone extinct (in other words bring them back
either from the brink of extinction or from extinction)? Explain your answer.

Answers

No, God gives and takes away, the world is heartless and kills entire species to extinction but it’s nothing that God didn’t already know would happen. Dinosaurs are no longer here there extinct for a reason, nowadays extinction comes from man but everything that happens in this world is Already written out in Gods book

Answer:

I think we should but people are preventing this though

Explanation:

I think we should because it might benefit the world and let scientists to discover this animal. But then I don't think so because animals that are/were extinct could perhaps be from climate change. Nowadays, people don't take this matter seriously causing habitats to be destroyed and animals to be extinct :) Like icebergs are melting that mean penguins are at risk of being extinct,if we did something then this situation will be prevented. However dinosaurs did become extinct and they did not come back so its probably just life and this is how god planned it:)

Genes:
A. in plants exist only in some individuals
B. they determine the structural and functional characteristics of each individual
C. they determine only the functional characteristics of each individual
D. they determine only the characteristics structural of each individual
E. do not exist in prokaryotes

Answers

Answer:

B. They determine the structural and functional characteristics of each individual

Explanation:

Genes are present in all plants and in all prokaryotes, so answer choices A and E are incorrect. Genes are present in all living things.

Genes do determine the structural characteristics of each individual, but they also determine the functional characteristics.

Structure, which is controlled by genes, directly affects function. For example, a gene could code for a specific protein's structure, which will in turn give it a specific function.

So, the correct answer is B.

8. Two rabbits are bred together. One is heterozygous for agouti coat
(genotype: Cch) and the other is albino. What are the possible phenotypes
of their offspring? Construct a Punnett square to support your answer.

Answers

Answer:

- Parental cross = Cch  x chch  

- F1 = 1/2 Cch (agouti coat); 1/2 chch (albino coat) >> 1:1 phenotypic ratio

Punnett  square:  

          ch         ch

C       Cch       Cch

ch    chch      chch

 

Explanation:

A heterozygous individual is an individual who has two different gene variants (i.e., alleles) at a particular locus. In this case, individuals having the "agouti coat" trait are heterozygous carrying both 'C' and 'ch' alleles. On the other hand, a homo-zygous individual has the same allele at a given locus (here, the 'chch' genotype associated with the albino phenotype). Therefore, as observed in the Punnett Square above, when a heterozygous parent is crossed with a homo-zygous recessive parent for a single gene, alleles segregate in the gametes of both parents so an expected 1:1 phenotypic ratio will be observed.

How does penicillin kill bacteria? Penicillin augments the body's natural ability to enzymatically degrade bacterial peptidoglycan, causing the cells to lyse Penicillin targets a cross-linking reaction in cell wall manufacture. By blocking the enzyme responsible, penicillin stops the bacteria from producing new peptidoglycan. Penicillin targets muramic acid in the cell wall. By damaging a key component of the cross-linking reaction, the cell can't build a strong peptidoglycan mesh and quickly breaks apart. Penicillin damages the lipid membrane of bacterial cells by enzymatically removing peptidoglycan from the membrane's outer surface. The weakened cells quickly lyse.

Answers

Answer:

The correct answer is option c. By blocking the enzyme responsible, penicillin stops the bacteria from producing new peptidoglycan.

Explanation:

Penicillins are derived from Penicillium molds. These are a group of antibiotics, used in treating various types of bacterial infections such as urinary tract infections, respiratory tract infections, gastrointestinal infections etc.

These antibiotics also used in treating gonorrhoea, meningitis, pneumonia, syphilis, etc. These antibiotics stop the bacteria from producing new peptidoglycan that blocks the enzyme.

Using sophisticated molecular cloning techniques, you have isolated the genes for two serotonin transporters, called TransA and TransB, which are expressed in these neuronal cells. A preliminary immunofluores- cence localization of fixed and permeabilized cells found very bright staining of TransA at the nerve cell plasma membrane and little staining elsewhere. TransB, in contrast, stained only very faintly at the nerve cell plasma membrane, but there was intense staining within the cytosol.

Required:
In which subcellular membrane or organelle would you expect most of the TransB to be found? Explain your answer.

Answers

Answer:

Vesicles  

Explanation:

Serotonin is a neurotransmitter that transports signals or messages between neurons.

Most neuronal cells have vesicles in their interior, which are organelles that store neurotransmitters for exportation -by exocytosis- or from recycling -by endocytosis-. These vesicles also protect the neurotransmitter from the enzymatic action.

Vesicles form in the cellular soma, from where they are transported to nervous terminals. Once the vesicle releases the neurotransmitter to the intercellular space, their membrane remains available in the plasmatic membrane to be reused.

The neurotransmitter concentration in the vesicle interior is related to the storage system and the transport system. There are specialized transporter proteins in the vesicle membrane that are involved with the introduction of the molecule to the organelle.

In the exposed example, transporter Trans B might be located in the vesicle membranes, and hence could be found in the cytosol of the cells.

Population - An individual life form. and Community - A group of populations.

What is population?

A population is the entire set of people in a group, whether that group is a country or a collection of people who share a certain trait.

A population is the group of people from which a statistical sample is taken in statistics. Therefore, a population is any collection of people who have something in common.

A statistically significant portion of a population, rather than the full population, may also be referred to as a sample. For this reason, the standard deviation, or standard error, of a statistical study of a sample from the full population must be disclosed.

Therefore, Population - An individual life form. and Community - A group of populations.
