Answer: Option D

Explanation:

The gemmulation can be defined as the aggregation of the cells mostly archeocytes when reserve food granules are isolated in a surface of sponge and it is surrounded a protective covering.

The Fragmentation can be defined as a process by which the  asexual reproduction in the multi cellular organism takes place. The fragments of the organism takes place and each fragment grows to form a new individual whose genetic combination is same like its parent.

Hence, the correct option is D

Answer:

d. Gemmulation involves providing a resistant layer of cells for a capsule; fragmentation is merely breaking off chunks of tissue to grow a new organism

Explanation:

Gemmulation and fragmentation are both a type of asexual reproduction. Gemmulation starts when mass of cell which is produced asexually that are capable of producing a new organism.  

These mass of cells gets surrounded by a protective covering which provide a resistant layer of cell and the structure is called gemmule.

In fragmentation, the parent body part breaks from the whole body and gives rise to a new organism. For example in planaria. So the correct answer is d.

Murljashka [212]

Answer:

a. In the presence of 2,4 dinitrophenol, which is soluble through the lipid membranes, the H+ gets an another route to pass through the membrane. It hampers the proton gradient potential without any generation of ATP. The gradient that was being utilized for the generation of energy is now just lost in the form of heat.  

b. With the reduction in the generation of energy, the cells get devoid of ATP, and drive the electron transport chain intensely so that the collapsing proton gradient gets re-established. However, it prevents the ATP synthase by providing a different path to the proton ions and thus diminishing the H+ concentration gradient.

The concentration of solute outside of the cell are_____than the inside of the cell
tatiyna

Answer:

If you place an animal or a plant cell in a hypertonic solution, the cell shrinks, because it loses water ( water moves from a higher concentration inside the cell to a lower concentration outside ). A single animal cell ( like a red blood cell) placed in a hypotonic solution will fill up with water and then burst.
