Which of the following regarding the assumption of sphericity is false? (Hint: Even very small departures from sphericity produce large biases in the F-test.)

Sphericity does not affect post hoc tests.

The effect of violating sphericity is a loss of power (i.e., an increased probability of a Type II error).

When sphericity is violated, we need to adjust the degrees of freedom for any F-ratios affected by the violation.

When sphericity is violated, the Bonferroni post hoc test can be used.

laila [671]

Answer:

There will be less animal life in lake Raymond in the next year.

Explanation:

In the year with heavy rain, this has caused the depth of Raymond lake to be increased. This will bring an increase in the growth and survival of more water plants and animal species.

In the second year where there is a decrease in the water level, the animals and water plants will face problems. The worst hit are those plants and animals species that lives at a much deeper path of the lake with the least sunlight or any external factors that are now going to be more exposed due to low water level..

mina [271]

There are fewer antifungal, anti protozoan, and antihelminthic drugs compared to antibacterial drugs because these cells can be similar to human cells and therefore they can not achieve selective toxicity.

<h3>What is drug selective toxicity?</h3>

The expression 'drug selective toxicity' makes reference to the ability of a specific medication to discriminate between cells of different organisms (in this case human cells and other types of eukaryotic cells).

Drug selective toxicity is a fundamental issue during drug discovery and drug development.

In conclusion, there are fewer antifungal, anti protozoan, and antihelminthic drugs compared to antibacterial drugs because these cells can be similar to human cells and therefore they can not achieve selective toxicity.

after administering a loop diuretic, a nurse monitors the client for increased urine output. what principle explains the seconda
Levart [38]

The correct answer for this question is Osmosis.

Osmotic diuresis is an increase in urine production brought on by the presence of specific chemicals in the tiny kidney tubes. When chemicals like glucose enter the kidney tubules and cannot be reabsorbed, excretion takes place (due to a pathological state or the normal nature of the substance). The compounds raise the osmotic pressure inside the tubule, which causes water to be retained in the lumen and inhibits water absorption, boosting urine production (i.e., diuresis). Therapeutics like mannitol, which is used to improve urine output and decrease extracellular fluid volume, have the similar effect.

By making the blood more osmolar, substances in the circulation can also increase the volume of fluid flowing through the body.
