The sodium-potassium pump regulates the amount of sodium and potassium inside of cells, particularly nerve and muscle cells. In this process, an ATP is burned, causing three sodium ions to be pumped out and exchanged for two potassium ions, which are pumped in by a membrane protein. Both ions go against their concentration gradients.
The sodium-potassium pump is an example of
a. phagocytosis.
b. passive transport.
c. active transport.
d. facilitated diffusion.

Which of the following is possible due to the high surface tension of water? *
A) Lakes don't freeze solid in winter, despite low temperatures.
B) A water strider can walk across the surface of a small pond.
C) Organisms resist temperature changes, although they give off heat.
D) Water can act as a solvent.
E) The pH of water remains exactly neutral.
Answers
Answer:
B) A water strider can walk across the surface of a small pond.
Explanation:
Water striders can walk on top of the water by using the high surface tension of the water and their long, thin legs to distribute their weight over the water. Their legs also have hydrophobic hairs which help them move over the surface.
A water strider can walk across the surface of a small pond, is possible due to the high surface tension of water.
What are Water Striders?Gerridae are one of the family of insects in the order Hemiptera, commonly known as water striders, water skeeters, water scooters, water bugs, pond skaters, water skippers, or water skimmers.
Consistent with the classification of the Gerridae as true bugs, gerrids have mouthparts evolved for piercing and sucking, and distinguish themselves by having the unusual ability to walk on water, making them pleuston (surface-living) animals.
They are built to transfer their weight to be able to run on top of the water's surface. As a result, one could likely find water striders present in any pond, river, or lake.
More than 1,700 species of gerrids have been described, 10% of them being marine.
What is Surface Tension?Surface tension in water might be good at performing tricks, such as being able to float a paper clip on its surface.
Surface tension performs many more duties that are vitally important to the environment and people.
Hence, option B is correct.

The process of transferring energy during respiration occurs in a series of steps. This prevents too much heat from being released at one time. Maintaining an appropriate temperature is beneficial to an organism because A) enzymes need a proper range of temperatures to catalyze vital reactions B) cellular waste products can only be excreted in cooler temperatures C) hormones can only produce antibodies if temperatures are not excessive D) nutrients diffuse faster into cells when temperatures are lower
Answers
Answer:
A) enzymes need a proper range of temperatures to catalyze vital reactions
Explanation:
Cellular respiration is the process by which living cells synthesize ATP (energy). The synthesized energy is transferred for use in other activities. However, as stated in this question, the process of transferring energy during respiration occurs in a series of steps in order to prevent too much heat from being released at once.
The process whereby the living organism maintains an appropriate internal temperature is called HOMEOSTASIS, which is beneficial and key to an organism's survival because because enzymes need a proper range of temperatures to catalyze vital reactions. Enzymes are proteinous catalysts that gets denatured by certain factors such as high temperature, pH.

:) The Big Bang Theory, describing the creation of the universe, is most directly supported by the
O redshift of light from distant galaxies
O presence of volcanoes on Earth
O apparent shape of star constellations
O presence of craters on Earth's Moon
Answers
Answer:
A
Explanation:
Redshift is when waves on the shift to the redder side of the visible light spectrum, meaning that they are becoming stretched out. This supports the theory that galaxies are moving farther away due to the momentum of the Big Bang, supporting the theory.
Hope this helps! Good luck :)
Big Bang Theory is an explanation that determines how the universe began and expanded. The universe is still stretching and it was started all at a single point.
The correct answer is:
Option A. redshift of light from distant galaxies
The redshift can be explained as:
1. The Doppler effect or red-shift of light from faraway galaxies gives the idea that the universe is expanding and stretching.
2. This accounts for the big bang theory in which space began from a single point and all the matter is moving away from the origin.
The correct answer is Option A.

The biomolecule described below is a _______________.
a. lipid
b. monosaccharide
c. carbohydrate
d. protein
Answers
Answer: it’s lipid
Explanation:
The biomolecule described below is a lipid because they are large and non-polluting molecules.
What is the main function of lipids?Lipids are responsible for providing energy, being in the form of fat that our body stores the excess energy we consume through food to use in times of need.
They are substances whose main characteristic is the insolubility in polar solvents and the solubility in organic solvents (nonpolar), presenting a hydrophobic nature, that is, aversion to the water molecule.
Lipids have unique characteristics that allow them to be quickly identified, for example because they are large and non-polluting molecules.

The base pairing rules for DNA are governed by the complementary base pairs: adenine (A) with thymine (T) in an A-T pairing and cytosine (C) with guanine (G) in a C-G pairing. Thymine only binds with adenine in a T-A pairing and guanine only binds with cytosine in a G-C pairing.
