Diffusion is the movement of particles from a high concentration area to a low concentration area.
Things that can go through a membrane are ions (charged), small polar molecules. Big molecules can't go through the membrane due to its large size and disrupting the membrane.
Passive transport is the movement of substances acrpss the cell membrane w/o the use of energy. Active transport needs energy to move substances across a cell membrane.
Answer:
Hey mate......
Explanation:
This is ur answer.....
1A) There are 2 ways:-
<em><u>•</u></em><em><u> </u></em><em><u>Anaerobic Respiration.</u></em>
<em>The anaerobic respiration process takes place in the absence of oxygen. </em>
<em><u>•</u></em><em><u> </u></em><em><u>Aerobic Respiration</u>. </em>
<em>In aerobic respiration, breakdown of pyruvate takes place in the presence of oxygen to give rise to 3 molecules of carbon dioxide and water.</em>
2A) <em>Oxygen is transported from lungs to body cells in the form of oxyhemoglobin . the main 2 gases exchanged are 02 & C02 . 02 is absorbed by blood capillaries from lungs alveoli by diffusion while C02 is absorbed by blood alveoli from blood capillaries by diffusion.</em>
Hope it helps!

Answer;
-5.83 AU
Explanation;
A year is defined as the time it takes a planet to complete one revolution of the Sun, for Earth this is just over 365 days. This is also known as the orbital period. Unsurprisingly the the length of each planet’s year correlates with its distance from the Sun.
Using the equation;
t² = a³
t = 3.24 years, the time it takes the planet to orbit .
a (astronomical units) = 3.24 ^3/2
= 5.83 anatomical units (AU).
The answer is A. random gene pool changes in small population.
Answer:
3/16
Explanation:
The following is the punnet square which represents the probabilities of offsprings being produced for this cross:
PR Pr pR pr
PR PPRR PPRr PpRR PpRr
Pr PPRr PPrr PpRr Pprr
pR PpRR PpRr ppRR ppRr
pr PpRr Pprr ppRr pprr
This cross shows that the probability of the offsprings to have white flowers and rounded seeds would be 3/16.
