Answer:

Answer is A. not produce the protein being studied.

Explanation:

The process of generating, creating or replicating a copy of a cell or an organism, which is genetically identical , is called cloning.

There are three types of cloning, these are

1. gene cloning... which is the process of replicating copies of genes.

2. reproductive cloning is the process of generating copies of whole organism.

3. therapeutic cloning... this process is always used when the aim is at creating or generating tissues in replacing diseased or injured tissue by producing embryonic stem cells for experiment.

The Gulf Coast Toad, Mexican Treefrog, and Couches Spadefoot Toad are all common species of amphibians found in the central Texa
Rasek [7]

Answer:

b. It allows all organisms to be placed into several varieties of taxonomic ranks.

Explanation:

A scientific name is important for every species because it helps to avoid confusion created by common names of two or more species or organisms. In every region there is a name for an organism which causes problem so the scientists suggest that there must be a naming system which is used all over the world so they choose a dead language to giving scientific names to the organisms present all over the world for easily recognition.

A nucleus within an ascus undergoes meiosis, producing four haploid spores, which then undergo mitosis, producing eight haploid
natima [27]

Answer:

Four.

Explanation:

Initially four haploid spores are produced by meiosis. We know that during meiosis pairing between homologous chromosomes occurs and this created genetic difference between the divided cells. Exchange of genetic material doesn't occur during mitosis so mitotically divided cells are similar. Thus when spores divide by mitosis and become eight in number, here will be no new genetic difference.

The complete sentence will be -

A nucleus within an ascus undergoes meiosis, producing four haploid spores, which then undergo mitosis, producing eight haploid ascospores. These haploid ascospores contain a maximum of four different genetic types.

Which of these is the best reason for doing more background research after making an observation and before forming a hypothesis
RSB [31]
The answer would be the second option. The best reason for doing more background research after making an observation and before forming a hypothesis is to prevent making the same mistakes made in a prior experiment. It is to make sure that you are able to see the problems of a research and make an experimental design that will minimize the errors.

If a large molecule needs to move against the concentration gradient, what structure will need to be used ?
strojnjashka [21]

Answer:

If a large molecule need to move against the concentration gradient the struc of an energy rich compound such as Adenosine tri phosphate or ATP is need to be used.

Explanation:

ATP provides energy to carry out the uphill transport of molecule across the plasma membrane by the helps of specific ion channel.Uphill transport is a type of membrane transport process in which a molecule is being transported against its concentration gradient that means the molecule is moving from low concentration region to high concentration region.

                In general this type of transport is Thermodynamically unfavorable which is made favorable by  the energy derived from the hydrolysis of ATP .
