1. Conservation biologists studying cheetah populations have determined that the lack of genetic diversity among the cheetahs is due to genetic drift. Which statement explains the most likely consequence of having a low genetic diversity on the cheetah population?
A. The gene pool remains in equilibrium and future generations of cheetah offspring are stronger and better adapted to their environments.
B. The cheetah population becomes less likely to survive an outbreak of a disease or an environmental change, increasing the chance of species extinction.
C. The chances of mutations occurring in the cheetah population are decreased, increasing the cheetah survival rate.
D. Genetic variability is maintained from older cheetah populations that have survived and endured environmental stressors.
Answer: it’s B
Explanation:
How does the mean speed of the water molecules change as they are heated
The average speed of water molecules increases as they are heated, it is due to kinetic energy.
How does water molecule changes due to heating?When change in temperature, there is also a change in the kinetic energy of the molecule. If an increase in temperature, the kinetic energy also increases. Thus, the movement of water molecules increases as we heat it up.
If molecules are heated up, it changes the kinetic energy and increases the collision and diffusion rate of the molecule.
When any substance gets heated it gains thermal energy and if cooled it losses thermal energy. If a molecule gets kinetic energy or a water potential is higher than the concentration of water in a system.
Therefore, the mean speed of the water molecules increases as they are heated.

Contact lens solution is salty in order to match your tears. Contact lens solution is ______________ to the cells in your eyes.
Is it hypertonic, hypotonic, or isotonic solution
Answer:
Its isotonic
Explanation:
Because The contact lenses that we wear have been formulated to be isotonic, which means that they have the same osmotic pressure as the tear film in our eye.
Contact lens solution is salty in order to match your tears, which is isotonic to the cells in the eyes. The correct option is C.
What is isotonic solution?Isotonic solutions have the same osmolarity (or solute concentration) as other solutions.
Water will flow in equal parts out of each solution and into the other if these two solutions are separated by a semipermeable membrane.
Isotonic solutions are used to increase fluid volume due to blood loss, surgery, dehydration, and extracellular fluid loss.
The contact lenses we wear are isotonic, which means they have the same osmotic pressure as the tear film in our eye's layer of lubricant bathing the cornea and conjunctiva.
The ocular tissues and the water in the lens must maintain equilibrium.
Thus, the correct option is C.

What is the difference between passive transport and active transport?
Answer:
Active transport requires chemical energy because it is the movement of biochemicals from areas of lower concentration to areas of higher concentration. On the other hand, passive transport moves biochemicals from areas of high concentration to areas of low concentration; so it does not require energy

C Oxygen is a product of cellular respiration.
D Oxygen is a reactant of cellular respiration.
Answer:
D
Explanation:
google cell respiration reaction
The statement which is true about Cellular respiration is as follows:
Oxygen is a reactant of cellular respiration.Thus, the correct option for this question is D.
What is Cellular respiration?Cellular respiration may be defined as a process through which organisms disintegrate the molecules of glucose in order to derive energy in form of ATP in the presence of oxygen.
The complete reaction of cellular respiration is as follows:
[tex]C_6H_1_2O_6+6O_2[/tex] → [tex]6CO_2+6H_2O+ENERGY.[/tex]This important reaction is carried out in the cell organelle known as mitochondria. This is because it is known as the powerhouse of the cell by the derivation of energy in the form of ATP. Although this chemical reaction is carried out in the presence of oxygen, it is known as aerobic respiration.
Therefore, oxygen is a reactant of cellular respiration is a statement which is true about Cellular respiration. Thus, the correct option for this question is D.

B. It is a relatively small atom.
C. It will do anything to fill up its electron shell.
D. It can bond with multiple other atoms at once.
Anybody know?
Answer:
it is b
Explanation:
The characteristic which is not true of carbon is: B. It is a relatively small atom.
Carbon can be defined as a non-metallic and tetravalent chemical element represented with the chemical symbol C and it has an atomic number (number of protons) of six (6). This ultimately implies that, carbon is found in Group 6 of the periodic table because of its six (6) valence electrons, that are found in the outermost shell of its atomic nucleus.
