Answers

The answer is d. mitosis.

The cells in the meristematic region of the root are embryonic cells. Thus, these undifferentiated cells have the capacity to undergo continuous mitotic divisions and divide into new cells. The meristematic region of the root contains meristem cells for the root growth.

Taller trees have a canopy arrangement of leaves where the upper leaves tend to be smaller than the ones below them. How does this arrangement of leaves benefit the plant?

Describe a medical advance that has led to a decrease in the spread of communicable diseases. What is the advance? How does it prevent the spread of disease?

Answers

Communicable disease or also known as infectious disease is the spread of disease from one person to another in a variety of ways: through air, contact with bodily fluids, discharges or blood, direct contact, and bites. Through the years, medical science had created lots of ways to control and prevent the spread of such diseases. One of these is the development of Immunization. Immunization works by preparing the body to fight foreign microorganisms that may harm the body. This boosts the body's natural defense against bacteria and virus by allowing the body to release more antibodies. This would enable to body to recognize the possible virus or bacteria that might invade inside the system.

Explanation:

A scientist is studying a gene implicated in cancer in mice. She samples 14,000 mice and her p-value is 5%. What should her conclusion be?

Answers

The given values are 14,000 sample size and 5% p-value. Statistical significant results are achieved when p-value is less than the significance level. This shows a 95% confidence of results in the samples. The rejection region is composed of 5% of the sample distribution.

Answer:

In conclusion the scientist should state that the data suggests that the gene causes cancer in mice.

Explanation:

A p-value is a measure of significance, it is the probability of the findings giving a false-positive of the hypothesis. A p-value less than or equal to 0.005 (5%) is considered significant. In conclusion the scientist should state that the data suggests that the gene causes cancer in mice.
