Answer:

Active transport uses energy to transport molecules across the plasma membrane. This uses energy from ATP. They also use pumps to get molecules in or out of the cell. Passive Transport does NOT use energy to transport molecules across the membrane.

Explanation:

on khan academy are four of them

Answer:

the 2 biotic factors are the plants in the corner and the 2 reindeer

The 2 abiotic factors in the image are the water and the mountains

The difference between the biotic and abiotic factors is that the biotic factors are living and the abiotic factors aren't living things.

The water gives nutrients to the reindeer.

Explanation:

Biotic factor are living things Abiotic factor are non-living things (;

Answer:

Carbon compounds: Chemical substances that contain carbon.

Answer:

B. Virus.

Explanation:

Hello.

In this case, since bacteria (A.) reproduce via asexual reproduction via mitosis and the animal (D.) and vegetal (C.) cells could reproduce via sexual or asexual reproduction depending on the organism, they do not need a host to start the replication of the DNA and therefore reproduce. In such a way, it is widely known that viruses need a host that facilitates the replication of their DNA or RNA (depending on the virus) since they only have their genetic information but they do not have neither the RNA nor the DNA polymerase that favor such process, that is why they need a host.

Best regards.

Given parameters:

Initial velocity = 25m/s

Final velocity = 30m/s

Time = 5m/s

Mass of runner  = 75kg

Unknown:

Force to finish the race = ?

Solution:

Force is defined as a pull or push on a body. According to Newton's first law, we can mathematically express force as the product of mass and acceleration;

          Force  = mass x acceleration

But we know that acceleration is the change in velocity with time, so;

           Acceleration  = [tex]\frac{Final velocity - Initial velocity}{time}[/tex]

So, force;

          Force  = mass x [tex]\frac{Final velocity - Initial velocity}{time}[/tex]

Input the parameters and solve;

        Force  = 75 x [tex]\frac{30 -25}{5}[/tex]  = 75N

The runner crosses the line with a force of 75N

Answer:

Explanation:

cellular respiration in eukaryotic cells takes place in the mitochondria. Both animal cells and plant cells depend on cellular respiration for their energy needs, because both animal cells and plant cells need ATP.

Answer:

8.7 (D)

Explanation:

A weak acid (anything below 7 on a PH scale) and a strong base (anything above 7 on a PH scale). The strong base will counter act the weak acid and dominate it meaning the answer will be above 7 giving you 8.7

The correct answer is 8.7

Answer:

Density of any substance or medium determine the amount of light that will be refracted.

Explanation:

Density of any substance or medium determine the amount of light that will be refracted.

The higher is the density of any medium, the higher will be the number of atom or molecules in a given medium and hence more obstruction will be produced for light. High density also causes high refractive index.  

The light usually bends away from the normal when light travels from a region of low to high density and light bends towards the normal when light travels from a region of high to low density

Answer:

Mesosphere

Explanation:

The Mesosphere is a layer of the atmosphere that is above the Stratosphere and below the Thermosphere. This is the third layer of the atmosphere. Some of its characteristics include;

1. It is constantly being hit by photons: These photons are in the form of meteors that constantly hit this layer of the atmosphere.  Meteors which are particles of dust release light energy that makes them visible to the human eyes as shooting stars.

2. The layer is characterized by very low pressure. This makes the air here thin and as the altitude increases, the air becomes very cold.

3. Temperatures decrease from 120° Celsius to -80° Celsius as you move down through the layer: The temperature in this layer decreases as the altitude increases.

Answer:

The ability of water to act as a solvent for so many substances is due to its structure, it can dissolve many ionic and polar molecules

Explanation:

polar nature Water's tendency to share electrons unequally makes it a polar molecule. The slight charge on either side of the water molecule allows it to bond (create a solution) with any atom with a positive or negative charge.
