I think the correct answer from the choices listed above is option B. It is marshmallows catching fore that is an example of a spontaneous exergonic reaction. An exergonic reaction is a chemical reaction where the change in the free energy is negative which indicates the reaction to be spontaneous. It happens without any energy input.
Answer:
When elongated, tube –shaped cells from the lining of the intestine are treated with a certain chemical in a dish, the cells sag and becomes round blobs. the internal structures disrupted by this chemical are probably microtubules
C. Diffusion.
The particles move WITH the concentration gradient
Answer:
The simple equation for lactic acid fermentation is glucose ---glycolysis---> 2 pyruvate ---fermentation--> 2 lactic acid. And the molecule for lactic acid looks like this: Lactic acid, also called lactate. This is the end product of lactic acid fermentation.
Answer:
b. phospholipid bilayer of membrane
Explanation:
The phospholipid bilayer evidently has in its structure mainly phospholipids, alcohol compounds and fatty acids.
Each molecule in the membrane phospholipid bilayer has two heads and a tail, both heads being hydrophilic (having affinity for water) and the tail being hydrophobic (having no affinity for water, and therefore repelling it).
This structure, with the heads, which are hydrophilic facing the intracellular and extracellular environments of cells, thus prevents the passage of polar compounds.
