cell organelles In this lab, you will try to view as many cell organelles as you can at different magnification levels. Write an
CaHeK987 [17]

Answer:

What is the effect of power/magnification on the frequency and size of organelles under a microscope?

Explanation:

Organelles within the cell are responsible for carrying out various functions. Some cells are more specialized than others, and may have particular organelles at a higher frequency, or showing a variation in size; sub-cellular structures become more visible at higher magnifications under the microscope.

Hypotheses:

  • organelle A's frequency decreases while B's frequency increases at higher magnifications
  • organelle A's size increases while B's size decreases at higher magnifications

<em />

<em>Dependent variables: size and frequency cell organelles</em>

<em>Independent variable:  power/magnification at low (x4), medium(x10) and high  (x40)</em>

<em>Controlled variables: Type of organelles, microscope used, cell examined, </em>

Method:

1. Examine the organelles A and B in a cell mounted on a slide; use the fine adjustment to focus on the cell.

  • Frequency:  What is the average number of organelle A versus B, seen at low (x4), medium (x10) and high (x40) magnifications?
  • Size: Measure the average diameter of organelle A versus B using an ocular micrometer at low, medium and high magnification.

2. Record and tabulate observations.

An example of the role of cultural practices shaping natural selection on genes that affect human health concerns
kaheart [24]

Answer:

The correct answer here is D) None of the above

Explanation:

Lactose intolerance and sucrose intolerance in themselves are not practices but side effects of practices that affect health concerns.

For instance, research shows that cultures with a long history of dairy farming and milk drinking or at least a history of drinking milk have a much higher likelihood to be <u>lactose tolerant</u> than those who don't. And when they can tolerate lactose their bodies take note of this and records the same in their genetic databank.

Cheers!

Which best matches the description with the genetic material? a. Nucleotides form a helical structure that is called a gene. b.
MAXImum [283]
DNA is the main type of genetic material found in a cell. In addition, it is found in the nucleus of the cell, so (D) is correct. DNA in the nucleus is used in replication (through mitosis and meiosis) via daughter cells to continue cell growth.
