Passive transport involves movement of substances

Biology
1 answer:
gtnhenbr [62]3 years ago
5 0

Answer:

Passive transport involves movement of substances from areas of higher concentration to areas of lower concentration.

Explanation:

Passive transport involves the passage of substances through a semi-permeable membrane, as occurs with transport at the level of cell membranes.

Generally, passive transport occurs with the <u>movement of compounds from the space with the highest concentration of a specific substance to the space with the lowest concentration of the same substance</u>, following the so-called concentration gradient. Theoretically, the gradient tends to disappear when the concentrations of substances have balanced out.

Regarding other options:

<em>     A. </em><u><em>From areas of lower concentration to areas of higher concentration</em></u><em>.  It is a feature of active transport.</em>

<em>      C. </em><u><em>From areas in which the concentration has reached a balance</em></u><em>.  There is no passive transport</em>

<em>      D. </em><u><em>From areas of differing concentrations with the use of cellular energy</em></u><em>.  Energy use involves active transport.</em>

The concentration of carbon dioxide in the atmosphere has been gradually increasing for many years. How might this increase affe
Assoli18 [71]

Answer:

It will increase the rate of photosynthesis as there will be more carbon dioxide ... however there may be a limiting factor which will limit the rate to keep it constant... Such as the opening if the stomata to receive more CO2 which in turn causes loss of water by transpiration.

Select the correct answer from each drop-down menu.
aksik [14]

Answer:

Just before the cat drops, it was stationery. Therefore it has energy of position called  potential energy.As it drops, the Gravitational potential energy is converted to Kinetic Energy,The conversion mid- air is P.E to K.E to P.E to K.E to P.E to K.E, until it touches the ground. As it touches the  ground all the energy is converted to P.E energy of position.

As it runs after mouse the P.E is converted back to Kinetic , energy of motion. As it feeds on the mouse , the chemical energy obtained  as protein from mouse meat.This is later converted back to Mechanical energy as (kinetic and Potential  energy)   in the cat.
