Which pair of terms concerning the osmotic effect of a solution on red blood cells is mismatched?
QveST [7]
Even though there are no choices given in this particular question, the principle of osmosis is very easy to understand. 

When we talk about osmosis, we are referring to the movement of water from a low concentration to a higher concentration. This is different from diffusion, which talks specifically about the movement of <em>solutes</em> in the solution (from a higher concentration to a lower concentration.)

When an RBC is placed inside a <em>hypertonic </em>solution, the water inside the RBC will go out thereby shrinking the RBC.

Inside an <em>isotonic</em> solution, the RBC will remain the same because the concentrations are equal.

Inside a <em>hypotonic</em> solution, the RBC will lyse or explode because water will move from the solution going inside the RBC.

A plant is treated with a chemical that blocks the flow of electrons between photosystem II and photosystem I, such that protons
Sindrei [870]

Answer:

Reduce or stop the production of energy molecule i.e ATP

Explanation:

Proton is an essential ingredient to carry out light reactions successfully and the proton requirement is fulfilled through the proton gradient formed along the membrane. A chemical that blocks the flow of electrons thereby hindering the flow of proton will adversely affect the electron transport chain reactions thereby causing reduced/no conversion of ADP to ATP.

which structure in leaves allows the gaseous reactants and products of photosynthesis to move in and out a b c d
Zepler [3.9K]

Answer:

Stomata

Explanation:

Photosynthesis is a unique phenomenon which occurs in the Chloroplast of plant cells. It is the way they synthesize their food in form of glucose. However, like every metabolic reaction, photosynthesis requires certain reactants and products.

Photosynthesis combines carbondioxide (CO2) gas and water (H2O) in the presence of sunlight to produce Glucose (C6H12O6) and oxygen gas (O2). The gaseous components of this metabolic activity enters (C02) and leaves (O2) the plant via a structure in the leaves called STOMATA.

STOMATA is a pore found in the epidermis layer of plant leaves that aids in the exchange of gases i.e. carbondioxide in, oxygen out during Photosynthesis.
