Calculate the net force of the following situation.

Biology
1 answer:
Llana [10]3 years ago
8 0

Answer:

D

Step-by-step equation:

-10 + 30 = 20

It's like walking ten meters to the left, then walking thirty meters to the right. The result is walking 20 meters to the right. It's the same with force.

During respiration, what do consumers such as animals release?
xxTIMURxx [149]

Answer:

Carbondioxide and water

Explanation:

During respiration food molecules are broken down to release energy. During this process oxygen is required and not formed but Carbondioxide and water is liberated as byproduct. So the closest answers are Carbondioxide and water

What property do the following elements have in common? Sulfur, iodine, magnesium
Luba_88 [7]

Answer:

Same Phase at room temp

Explanation:

Here we have a metal and two nonmetals (sulfur and iodine).

They are all solid at room temperature. Metals form cations and are good conductors of electricity. They are not from the same family, therefore, they do not have the same number of valence electrons.

Grasses → mice → cat → coyote As matter and energy move from grasses to coyotes the amount of available energy
Gnesinka [82]
The answer would be C. Energy is used through the food chain so energy always decreases. Population size would commonly decrease according to the  pyramid of food chain but since there's no answer for that, C would be the most suitable

suppopse you were going to deisgn a system for the rapid diffusion of oxygen across a phosphlipid bilayer. according to fick's l
Llana [10]

Answer:

According to Fick's law, the rate of diffusion of any substance across any barrier is<u> directly proportional to the surface area of the membrane or any layer exposed. and the concentration of the diffusing substance available, but the rate is inversely proportional to the diffusion distance available.</u>

<u />

Thus the rate at which oxygen will move across the phospholipid  bilayer will depend on the concentration or amount  per mole  of the oxygen molecule hitting the phopholipid at  a prticular time and how permeable the phospholipd layer is to oxygen molecules, but the rate of its  movement across will be reduced as the distance between the phosphoslipid bilayer and the diffusing molecules  increases.

Therefore, the concentration of oxygen should be maximised, the surface area of the phospholipid  bilayer should also be maximized. the distances between the phopholipid and the  vessel containing the diffusing oxygen molecules should be drastically reduced. With this Fick's law  has been applied , and therefore maximum oxygen molecules can diffuse across.
