Answer:

The correct answer will be option C.

Explanation:

Chromosome is a packaged structure of DNA observed in the cell nucleus during metaphase stage of cell division when aligned in the equatorial plate of the cell.

Chromosomes number varies in different species which facilitates replication and distribution of the DNA to new daughter cells during cell division.

Chromosome is formed after coiling of DNA many times around proteins called histones which provides the structural support to DNA and form a special structure nucleosomes,  further coil up and create chromatin loops which further coil around each other and make a full chromosome.  

Thus, option C is the correct answer.

No, it's not B. The energy needed to "pump" sodium outside the cell in active transport is ATP. When ATP releases energy (for metabolism usage) during active transport, the sodium is discarded.

An enzyme that follows simple michaelis–menten kinetics has an initial reaction velocity of 10 μmol⋅min−1 when the substrate con
svet-max [94.6K]

The Vmax of the enzyme is 12 μmol⋅min−1

We use Michaelis-menten equation,  which is given by;

V=\frac{Vmax(S)}{Km+(S)} \\

Where v is velocity of reaction

Vmax = maximum rate achieved by the system

[S] = concentration of a substrate

K_{m}= Michaelis constant

Given V_{0} = 10umolmin^{-1}

[S] = 5km

Now, we calculate Vmax:

10umolmin^{-1} = \frac{Vmax*(5Km)}{Km+5Km}

Km = 1

10=\frac{5KmVmax}{6Km}

\frac{10*6}{5} =Vmax

Vmax =12 μmol⋅min−1

Explain in detail about Phospholipid Bilayer.
erica [24]

A phospholipid bilayer or lipid bilayer is a double layer of lipids in a cell membrane which has a hydrophobic and a hydrophilic part.

Hydrophobic - expelled by water

Hydrophilic - attracted to water

The layers form the cell membrane which means that it's functions are the same as the functions of a cell membrane, and are critic to the cells functioning.



Hope it helped,
