Answer:
VDF= Vm- Veq.
Where VDF = Electrochemicall driving force
Vm=Membrane potential
Veq.=Equilibrium potential for the ion of interest
Ideally when VDF=0 at Electrochemical equilibrium, i.e. Vm=Veq, there is no net movement of ions across the membrane.
So, Answer is (D) This scenario is impossible.
Oxygen molecules are too small and glucose molecules are quite large than oxygen. So they can't passively disuse inside a cell.
Option C
<h3><u>Explanation:</u></h3>
Glucose molecules are large molecules with a molecular formula of C₆H₁₂O₆ These molecules need special protein channels or transporters called Glucose Transporters or GLUT to make them way through the cell membranes. While smaller molecules like oxygen, carbon dioxide, smaller polar molecules like <em>water</em> or even fat soluble molecules like chloroform and benzene do pass through the membranes easily by means of passive diffusion.
The oxygen molecules are needed inside a human cell for aerobic respiration and glucose molecules are needed because of a respiratory substrate. So Glucose needs receptors and transporters to pass through the membranes.
Answer:
The opposite of hyper- is hypo-. hypo-: Prefix meaning low, under, beneath, down, below normal. For example, hypocalcemia is low calcium in the blood and hyposensitivity is undersensitivity.

Klinglers iron agar medium is used to find the enterobacteria which can ferment glucose , lactose and hydrogen Sulphide . They are H₂S producing bacteria .
This media have phenol red as an indicator. When the glucose is fermented to acid , the production of acid turn the indicator from red to yellow, but it is then reoxidised and turns red again . When lactose is fermented it produce large amount of acid , and turn indicator yellow . Hence the slant will become yellow.And combination of ferrous sulphate and sodium thiosulphate helps in detection of H₂S which produce black color at the butt .

D.) COLORFUL FLOWERS is the structural adaptation that some plants have to attract pollinators.
The more colorful the flowers are, the more insects are attracted to the flowers. Insects would then land on the flowers wherein the pollen in the flower will stick to the body of the insect. Insects are called pollinators. They help in the pollination of the flowers.
Pollination is the transfer of pollen from the flower's anthers to its stigma or another flower's stigma which will start up its fertilization.
