Answer:
The correct answer is: C. Active Transport.
Explanation:
Because Na+ and K+ are ions, which makes them charged molecules, they can only diffuse through the cell membrane when using specialized protein channels. This is called facilitated diffusion and is a form of passive transport because sodium and potassium move following their gradients, which are made of the difference in concentration between the inside of the cell and the outside of the cell. For example, potassium is highly concentrated inside the cell and poorly concentrated outside the cell, so potassium diffuses from the inside to the outside to even the concentrations.
But the question asks in which process Na+ and K+ move in and out of the cell SIMULTANEOUSLY, so the answer is actually active transport. Active transport is the opposite of passive transport. While passive transport occurs naturally and doesn't need ATP (energy) to happen, active transport needs ATP because it moves molecules AGAINST their gradient. One of the most famous and important structures involved in active transport is the Na+/K+ pump, which consists of a specialized protein using energy to enter 2 potassium ions and take out 3 sodium ions at the same time. This Na+/K+ is fundamental to maintain the gradients, which are important for the correct functioning of many cells.

How are luminosity and magnitude related?
(In your own words)
Answer:
Luminosity is an intrinsic(natural) measurable property of a star independent of distance. The concept of magnitude, on the other hand, incorporates distance. The apparent magnitude is a measure of the diminishing(decrease) flux of light as a result of distance according to the inverse-square law.

The speed of an angry goblin is equal to 8 miles per hour, if it flies 32 miles in 4 hours.
Given the following data:
Distance = 32 miles. Time = 4 hours.To determine the speed of an angry goblin:
Speed can be defined as the distance covered by an object per unit time and it is usually measured in meter per seconds (m/s).
Also, speed has magnitude but no direction and as such it is a scalar quantity.
Mathematically, speed is given by the formula;
[tex]Speed = \frac{distance}{time}[/tex]
Substituting the given parameters into the formula, we have;
[tex]Speed = \frac{32}{4}[/tex]
Speed = 8 mi/hr.
Therefore, the speed of an angry goblin is equal to 8 miles per hour, if it flies 32 miles in 4 hours.

Which is a correct statement?
Select one:
a. As porosity increases, permeability stays the same
b. As porosity increases, so does permeability
c. As porosity increases, permeability decreases
d. Porosity and permeability are unrelated
help pls!!!
As porosity increases, permeability decreases It increases as particle length increases. via definition, permeability is a measure with which fluids will go with the flow though a porous rock, soil or sediment. a material that has high porosity does not have to have high permeability.
Smaller particles have a low permeability. this is due to the fact there's less space among debris, which reasons a lower porosity, which makes water travel slower through the ground. Smaller debris have a higher capillarity.
Porosity is the amount of pore area that is between particles in soil or rocks. Permeability takes this pore space and connects the voids collectively so that water can pass thru. Porosity is extra associated with garage of water, whilst permeability is extra related to groundwater motion and flow.
To calculate the permeability of a porous material, use Darcy's law equation: Multiply together the fluid discharge fee, dynamic viscosity, and distance traveled. Divide the end result from step one with the aid of the move-sectional place of the fabric elevated with the aid of the strain difference on either aspect of the material.

A disadvantage of using nuclear power is D. Nuclear power produces radioactive waste.
What is nuclear power?Nuclear power is a controversial topic, with proponents arguing that it is a clean and efficient source of energy, while opponents point to the risks of accidents and the dangers of radioactive waste.
One of the main disadvantages of nuclear power is that it produces radioactive waste. Radioactive waste is a byproduct of the nuclear fission process, and it can remain radioactive for thousands of years. This makes it difficult to store and dispose of safely. Another disadvantage of nuclear power is that it is expensive to build and operate nuclear power plants.
