Georgia [21]

A) C. group: Group B, I. variable: Special juice, D. variable: Stacks of papers made. B) C. group: Half of the shower sprayed with water I. variable: coconut spray D. variable: change in green slime. C) C. group: members who do not use the product, I. variable: Grow Long use, D. variable: Speed of hair growth.

<h3>Control group</h3>

The control group is selected from the same population as the treatment group.

These two groups are identical in all aspects except for the independent variable that the researcher changes in the experimental group to observe how they affect the individuals.

The control group is used to identify if there are any other factors influencing the results obtained by the treatment in the study, from the results that might be a consequence of other factors.

Data from an experimental group are compared with the data from a control group.

<h3>Independent Variable </h3>

Refers to all the variables that provoke a response in another variable.

An independent variable is the one that changes or is controlled and modified to analyze how another variable responds to it.

It changes to analyze its effects on the dependent variable.

<h3>Dependent Variable</h3>

The dependent variable depends on any change in the independent variable.

Its value depends on how the independent variable is modified.

The change in the dependent variable might be either proportional or inversely proportional to the change in the manipulated variable.

A) Control group: Group B, who is not given the special juice.

Independent variable: Special juice ingestion.

Dependent variable: Stacks of papers each group makes.

B) Control group: Half of the shower sprayed with water

Independent variable: Coconut juice spray

Dependent variable: change in the appearance of the green slime.

C) Control group: The members of the family that do not use the product

Independent variable: Grow Long use

Dependent variable: Speed of hair growth

ArbitrLikvidat [17]

<span>the one that best describe red blood cells is : C. they transport oxygen throughout the body NOT A, because like its name, it has the color of red, not colorless NOT B, the one that protect our body against disease-carrying microorganism is white blood cells Not C, because the one that aid in blood clotting is the Vitamin K that contained in white blood cells</span>

What is the most likely cause of LS’s potassium imbalance? Explain the role of the kidney in potassium excretion.

Scorpion4ik [409]

L.S. is brought to the emergency department for management of acute mushroom poisoning. Her respirations are slow and shallow, and she is nonresponsive. She is admitted to the critical care unit to be closely monitored for the development of respiratory failure and renal failure, which often accompany mushroom poisoning. Her urine output is decreased to about 20 ml/hr. Her laboratory values are serum K+ = 5.7 mEq/L; arterial blood gases (ABGs): pH = 7.13, PaCO2 = 56 mm Hg, PaO2 = 89 mm Hg, HCO3- = 18 mEq/L.

1A. What is the most likely cause of L.S.’s potassium imbalance? Explain the role of the kidney in potassium excretion

Answer: L.S. is experiencing a intrarenal acute renal failure in the category of tubular necrosis (due to ingested mushroom toxins).

The kidneys helps to maintain the electrolyte concentrations by filtering electrolytes and water from blood, routing some to the blood, and excreting any excess into the urine.

Therefore, the kidneys help to maintain a balance between daily consumption and excretion of electrolytes and water.

Explanation:

Daily variations in potassium excretion are controlled mainly by changes in secretion in distal and collecting tubules.

• Maintaining potassium balance depends primarily on renal excretion which is determined by:

• the rate of potassium filtration

• the rate of potassium reabsorption by the tubules o the rate of potassium secretion by the tubules

i.e. About 65% the filtered potassium is reabsorbed the proximal tubule and another 25% to 30% in the ascending loop of Henle.

What are the main principles of the natural selection?

netineya [11]

(Variation.)Heritable differences that exist in every population are the basis for natural selection.

(Overproduction). Competition between offsprings for resources.

(Adaptation.) a trait that helps an organism survive and reproduce.

What is an adaptation for cold,snow -covered environments

SIZIF [17.4K]

Animals have to adapt to the food that live there plus if there is a body of water fish and organisms that live in that water have to adapt to the type of fish in that water.
