Excited about the fungus chemical's promise for treating cancer, you write up your experimental results and send the paper to a

prestigious scientific journal, hoping it will be published. The journal sends your paper out to several scientists for evaluation--a process known as peer review. The reviewers identify several issues with the experimental design and data presented in your paper. Which of the following criticisms are valid issues of concern that peer reviewers might identify?
A) The effect may not be real because we don’t know if the results are reproducible.
B) Cell samples were taken from too few patients.
C) The experiment should have been run for more days in order to make the effect of the fungus chemical clearer.
D) There was no control in the experiment.
E) The treatment kills cancer cells, but it might simply be a poison that kills all cells—even normal cells.

Answer:

The correct answer is option A, B, and E.

Explanation:

The peer review can only be made only on the basis of the results that are published in the journal for treating cancer by fungus chemicals. On the basis of the result the reviewers will have the only idea about limited things such as-

Reviewers can get an idea about if results can be reproducible or not and on the basis of that, it may possible that the effect is not real. Results can give idea about the sample size so it may possible to criticize the sample is small. The chemicals can be effective on the cells as promised but it may also possible that they might kill the normal cells too.

Thus, the correct answer is option A, B, and E.

Damian grew a plant from a leaf cutting. How did the plant reproduce?
ycow [4]
A plant grew from a leaf cutting will reproduce asexually.A plant cutting  refers to a piece of plant that is used to vegetatively propagate a plant. A plant cutting can be a piece of stem, root or leave. The plant cutting is usually placed inside a suitable medium, where the cutting will grow to produce a new plant under suitable conditions. Plants that are grown from plant cutting are considered to be reproduce asexually, because vegetative propagation is a form of asexual reproduction.

PLEASE ANSWER QUICK ;(
Neko [114]

Answer:

The correct answer is A. Since the Earth has a tilted angle of 23.5 degrees as it moves around the sun, the amount of sunlight that is received by the hemispheres vary from time to time. This is mainly responsible for the changes in the temperature and daylight hours, which are the indicators of the changes in seasons.

In this case, when one hemisphere of the Earth is tilted toward the sun, it receives more sunlight than the other end. Therefore, this region experiences summer, wherein the daylight is longer and the temperature is warmer

A scientist is comparing cancerous cells with noncancerous cells.
Simora [160]

The scientist should notice that the cancer cells have a <u>higher</u> rate of cell division and  have a <u>lower</u> response to inhibiting factors. Cell groups that are cancerous should  have a <u>lower</u> percent of cells in interphase than noncancerous cells.

Explanation:

The general characteristics of cancerous cells are defined by the ‘hallmarks of cancer’ like ‘enable replicative immortality, activate invasion and metastasis, resist cell death, evade growth suppressors’ etc. All these facts prove that they grow and divide at a higher rate and undergo uncontrollable mitotic cell division leading to proliferative invasion.

The cancerous cells also show low or no response to inhibiting factors like growth suppressors like p53, cyclins and other anti-tumor drugs.

The number of cancer cells in interphase is lower than noncancerous cells because interphase is a phase of cell growth, development and differentiation. Cancer cells undergo uncontrollable mitosis and more time is spent after the interphase to facilitate rapid cell division rather than growth or development.
