How does the contractile vacuole in a single-celled organism function to maintain homeostasis?a. It pumps water into the cell.
b.It pumps water out of the cell.
c.It pumps solutes into the cell.
d.It pumps solutes out of the cell.

Answers

Answer 1
Answer:

Answer: "Option B- It pumps water out of the cell".

Explanation:

Vacuoles in the cell organism are responsible to maintain the amount of water in the cell body, to get stable in the environment vacuoles either  remove or absorb the water through the mechanism of osmosis or osmoregulation.

Homeostasis is the phenomenon of maintaining balance of physical and chemical conditions of organism according to the environmental conditions to survive in it.

In single celled organisms, contractile vacuole pumps out the water from the cell through osmoregulation and excess of water is pumped out by the contractile vacuole.      

Answer 2
Answer: It's b. When placed in a freshwater environment, the organism is in a hypotonic solution, so water would flow into the organism. To prevent from bursting the vacuole constantly pumps water out to make up for this.

Answers

Answer:

Animals, including humans, store glucose in the form of  glycogen.(option 2)

Hope it helps :)

Final answer:

Animals, specifically humans, store glucose in the form of glycogen. Glycogen serves as an energy storage molecule which can be broken down into glucose when needed. Cellulose, wax, and lipids have different roles in the organism.

Explanation:

Animals, including humans, store glucose in the form of glycogen. Glycogen is a polysaccharide, or a complex carbohydrate, that our bodies use for energy storage. It is stored primarily in the liver and muscle cells. When our bodies need a quick boost of energy, glycogen is broken down into glucose molecules that can be utilized by the cells. It's unlike cellulose which is a structural component for plants, whereas wax and lipids play a different role in the organism.

Which of the following planets has the lowest average density?1) Venus
2) Mercury
3) Earth
4) Mars

Please explain

Answers

The planet that has the lowest average density is Mars. The correct option is 4.

What is average density?

The entire mass of a region divided by the total volume of that region yields the mean or average density.

By multiplying each compound's density by its volume and then dividing the result by the sum of all the volumes, one can determine the mixture's average density.

The average density of different planets is:

Venus; 5.2

Mercury; 5.4

Earth; 5.5

Mars; 3.9

So, the lowest density out of these planets is Mars. Density is something's concentration. If the density is low, the weight of the object will be low. When placed in water, an object will float if its density is lower than that of the water, whereas it will sink if its density is higher.

Therefore, the correct option is 4) Mars.

Mars because it has low levels of gravity and if given the oppurtunity could float on water.

What part of a wind turbine provides motion to convert into electricity?a. generator
b. blades
c. tower
d. rotor

Answers

There are twotypes of modern wind turbines. In a Verical-axis wind turbines (VAWTs), theshaft is mounted on a vertical axis perpendicular to the ground. They arealigned with the wind so there’s no adjustment necessary when the winddirection changes. It can’t start moving on itself that is why it needs a boostfrom its electrical system to get started. It uses wires for support so therotor elevation is lower. They are less efficient than HAWTs due to its lowerelevation. Lower elevation means slower wind due to ground interferences. Theother type is Horizontal-axis wind turbines (HAWTs), the shaft s mountedhorizontally parallel to the ground. It is constantly aligned with the windusing a yaw-adjustment mechanism. This mechanism moves the entire rotor left orright in small increments. It uses a tower to lift the turbine components to anoptimum elevation for wind speed and take up very little ground space. It ismuch more efficient than VAWT. The motion that converts into electricity is therotor. The answer is letter D.

The answer is B. blades, I just took the test.
