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.
Answer:
The correct answer is option 1. "Amplitude".
Explanation:
Waves of sound have different properties, among them amplitude is the one that determines the loudness or volume of the sound. The amplitude is the height of the wave, measured in meters, or in other word the maximum displacement of the sound's particle from its position of equilibrium. If a dolphin calling sounds louder because of the background noise, the waves of the sound that the dolphin produces would have a higher amplitude.

The central element for all living things is carbon, which is why you might often hear the phrase "carbon-based" lifeforms. Another term is often "organic matter"
Answer:
- <u>Option:(D)-</u> Cushing's syndrome.
<em>"The disorder is formed inside the body due to having a higher level of cortisol hormones in the blood."</em>
Explanation:
- <u>Drug Induced hormonal imbalance:</u>
Exogenous Cushing's syndrome is mainly caused by the intake of a man made synthetic drug named as <u>glucocorticoid medicines.</u> As the drug causes the imbalance in the level of hormone cortisol inside the blood plasma, which lead us to having severe case of having more cortisol produced by the adrenal glands.
