Natural selection is the increased survival of a species because of certain traits that allow them to reproduce and survive and higher rates than others.

Natural selection happens only in certain animals because of the fact that bacteria produce asexually and both plants and fungi are all too similar to even compete with one another. We see this in our own backyard (or just outdoors), since many grasses can thrive all at once without competing with one another.

Natural selection is only performed in bacteria because of the limiting factor of producing asexually. Since they are produced asexually, all of them are very different from the parent and can thrive by continually reproducing very fast.

None of the previously mentioned.

All except for the fourth.

False

The atomic number is the amount of neutrons in an element; however, both the atomic mass, and the the number of electrons add up to give you the total amount of subatomic particles in an element, or, more commonly known as the amount of neutrons in a substance

The atomic number tells how many protons and electrons an element has.-- The atomic mass tells the amount you get when you subtract the protons from neutrons.--You cannot find the number of protons.

The atomic number of an element represents how many protons and electrons an element has.--The atomic mass of a number is the number of neutrons and protons an element has/how much the element weighs.--You find the number of neutrons in an element by subtracting the amount of protons from the atomic mass.

All of these are correct!

All of these are incorrect!

Diffusion is the passage of materials through the cell membrane by moving down the concentration gradients.

Diffusion uses ATP and other types of energies to move across the cell membrane.

This is the passage of air through our lungs, which results in our blood carrying oxygen to the cells.

This is the passage of materials in and out of the cell using a vesicle. AKA - Endocytosis and Exocytosis

TRUE

FALSE

The ER supplies the cell membrane with what it needs to form.

The ER serves as the transportation system within the cell. It transports things that are within the cell to other parts in the cell.

The ER transports things inside of the cell out of the cell.

The ER is one of the cell's main source of protein and lipids.

Hypertonic means the cell has more salt so it gives up water and shrinks.

Hypertonic means the cell is at complete balance.

Hypertonic means the cell has more water than salt so it continues to take in and swell with water.

Hypertonic can mean many things and all these are correct.

No--Just, No.

its offspring greatly varies from the parent.

its offspring are all still attached to the parent and will always be until they die.

its offspring are all identical to the parent.
