When a bacterial cell is present in an environment where both lactose and glucose are present, the glucose will be metabolized f
Umnica [9.8K]

Answer:

Option (A).

Explanation:

Lac operon system in bacteria explains the lactose metabolism in the cell. The first operon system was discovered by Jacob and Monod. Operon may be defined as the cluster of genes that are transcribed as a single RNA unit.

The bacteria uses glucose if glucose and lactose are present in the media. The bacterial cell can recognize the glucose presence as CAP-cAMP complex are required for the process of transcription and the complex level is low in the presence of glucose. This way bacteria turns off transcription for lactose genes even when the lactose is present.

Thus, the correct answer is option (A).

Ludmilka [50]

Answer:

DNA replication is faster and microscopic in size, smaller than eukaryotic cell.

Explanation:

The three domains of life are archaea, bacteria and eukarya. The two main biological division are prokaryotes and eukaryotes. The organisms that lacks the complete nucleus are included in prokaryotes.

The DNA replication is quite fast in prokaryotes as compared to eukaryotes because of small genome size, transcription is coupled with the translation and no post transcription modification is present in prokaryotes. The size of prokaryotes is quite small as compared with eukaryotes and shows the fast rate of diffusion.

Thus, the answer is option (a) and (c).

Which of the following statements correctly determines the process when following the scientific method?
crimeas [40]

Answer:

A) Formulate question,conduct research,propose hypothesis,test hypothesis

Explanation:

The scientific method is pertinent to the success of a scientific experiment. The scientific method is a sequential steps of processes involved in an experimentation. The correct order of steps that determines the process when following the scientific method are:

1) Formulate question: Asking a question about what has been previously observed is the key to starting a scientific method.

2) Conduct research: Research is done based on a previous observation that has been made by in order to gather necessary information.

3) Propose hypothesis: A hypothesis is a predictive statement or explanation to an asked question about the experiment that can be tested. It usually goes in an IF, THEN format.

4) Test hypothesis: As stated in the previous step, a hypothesis must be testable, which is done by conducting an experiment. The outcome of the experiment proves or disproves the hypothesis.

Explain why five leaf discs of each leaf type were used
satela [25.4K]

Usually in experiments, you want multiples of the same thing so the data is accurate and consistent and not just some fluke and to make sure you didn't have some major error you missed.

A fly has two alleles for the color of its eyes. The green allele is recessive, and is represented by q. The blue allele is domi
murzikaleks [220]

Answer:

p = 0.34

Explanation:

The green allele is recessive, meaning two copies of q (qq) are required to be green. Conversely, animals that are either pp or pq will be blue.

If 44 organisms are green, that means 44 are qq.

For genotype frequencies, the equation is:

homozygous dominant genotype + heterozygous + homozygous recessive = 100%

Which is denoted as

p² + 2pq + q² = 1

We know that q² = 44/100 = 0.44

To work out q, we can do \sqrt{0.44} = 0.66

For allele frequencies, the total must add up to 100%, so

p + q =1

We know that q= 0.66

So p = 0.34, because 0.66 + 0.34 = 1
