Membrane proteins called pumps use energy to move hydrogen ions to one
side of the membrane. Which term describes the difference between the
numbers of hydrogen ions on opposite sides of the membrane?
A. lon concentration
B. Concentration gradient
C. Homeostasis
D. Equilibrium
Answer:
Explanation:
Pumps, also called transporters, are transmembrane proteins that actively move ions and/or solutes against a concentration or electrochemical gradient across biological membranes. Pumps generate a membrane potential by creating an electrochemical gradient across the membrane.

Why does earth turn so slowly?
Answer: Earth's rotation is slowing slightly with time,thus, a day was shorter in the past. This is due to the tidal effects the Moon has on Earth's rotation. Atomic clocks show that a modern-day is longer by about 1.7 milliseconds than a century ago.
What are Species Survival Plans meant to do?
A. Attract visitors to zoos and aquariums
B. Eradicate invasive species
C. Promote sustainable trade
D. Reintroduce endangered species to the wild
Answer:
it would be option D
Explanation:
This is becuase the goal of their program is to foucs on near threatened, threatened, endangered, or otherwise in danger of extinction in the wild, when zoo and zoology conservationists believe captive breeding programs will aid in their chances of survive. When they are done with the capive breading the animals can be relised back into the wild.

Select all the correct answers. Researchers are studying possible ways to use the process of nuclear fusion to generate electricity. In what ways would fusion be better than fission for use in power plants? The fuel used for fusion is abundant in nature and easy to obtain. Fusion occurs at ordinary temperatures and pressures. The fusion process doesn't require an energy input. Fusion has fewer safety risks than fission. Fusion doesn't produce radioactive waste products.
Answer:
Fusion doesn't produce radioactive waste products.
Explanation:
Fusion type of reaction does not produce any type of radioactive waste products, it produces helium, neutron and releases huge amount of energy while on the other hand, fission reaction causes the splitting of a single nucleus into two which produces gamma radiation and releases huge amount of energy so by seen the products we can say that fusion reaction doesn't produce radioactive waste products but the fission reaction can produce.
How are many unicelled organisms. In addition , anything less than a cell is not alive. What do these statements imply about cells?
Answer:
The correct answer is - cells are the basic unit of life.
Explanation:
As it is given and also known that there are many unicellular organisms exists and they do not require the multicellular body to live their life or survival. Multicellular organisms are made up of various cells joined together to form a complex organization.
Anything less than a cell can not live or survive and also do not called a living entity. So, from above we can say the basic unit of the life is cell.

In the simulation, when protein molecules were evenly distributed on both sides of the membrane, was the solution isotonic, hypertonic, or hypotonic? Which direction was water flowing?
Answer:
1. Diffusion is the process of a substance moving from an area of high concentration to an area of lower concentration. Osmosis is a type of diffusion where water moves across a semipermeable membrane still from an area of high concentration of water to an area of lower concentration of water. This corresponds to water moving from an area with a low concentration of solute to an area with a higher concentration of solute.
2.
a. A semipermeable membrane allows some substances to pass through it.
b. The plasma membrane of a cell allows small uncharged molecules to pass through it, but not large molecules and not charged ions.
3.
a. The protein molecules were evenly distributed on both sides of the membrane, so this solution was isotonic.
b. In an isotonic solution, water moves both in and out of the cell, which was observed in the simulation.
4.
a. The protein molecules were more highly concentrated on the inside of the cell, so this solution was hypotonic.
b. In hypotonic solutions, water moves into the cell to help dissolve the higher amount of solute inside the cell, which was observed in the simulation.
5.
a. A semipermeable cell membrane is important to allow some molecules, like proteins, to be more highly concentrated inside the cell than outside the cell. If the cell membrane were permeable, the molecules on the inside of the cell would exit the cell and be evenly distributed in the cell and in its environment.
b. If the cell membrane were not permeable at all, the cell would not be able to receive nutrients from its environment.
Explanation:
When protein molecules were evenly distributed on both sides of the membrane, the solution is isotonic.
In isotonic solution the concentration of solutes on side remain same .There is no net gain or less of water in isotonic solution.What will be the direction of water flow in isotonic solution?The water will flow freely across the cell membrane without any change in the concentration of solutes.In isotonic solution the cell neither shrink nor swell because the water concentration will remain same.To know more about isotonic solution here

Which of the following statements about cellular respiration is true? Group of answer choices In glycolysis, NAD+ is oxidized to form NADH. In the electron transport chain, NAD+ is oxidized to form NADH. In the electron transport chain, NAD+ is reduced to form NADH. In glycolysis, NAD+ is reduced to form NADH.
Answer:
In glycolysis, NAD+ is reduced to form NADH.
Explanation:
NAD+ gains an hydrogen electron in the glycolysis pathway which translates to a reduction and not an oxidation.
There is also a subsequent oxidation that takes place in the electron transport chain system.
This facts makes NAD+ as being reduced to NADH in glycolysis as the right fans best option to choose from.
