Condensation of DNA forms the chromosomes and the DNA contains the genes.

<h3><u>Explanation:</u></h3>

DNA is the complex polymer of different nucleotides which stores the genetic information inside each and every cell of an animal. A DNA molecule is very long, which is stored inside the nucleus of an eukaryotic cell. In case of prokaryotic cells, the DNA molecule remains present inside the cytoplasm of a cell.

The Chromosomes are the condensed DNA which are seen inside the cells which are going to divide in near future. In these cells for the sake of efficient chromosome separation, the DNA condenses into chromosomes with the help of different histone and non histone proteins.

Genes are particular parts of DNA which comprise of a group of nucleotides and together, they translate into a protein chain with specific function in body.

The amount of energy that must be absorbed or lost to raise or lower the temperature of 1 g of liquid water by 1°c _____.

Fiesta28 [93]

Answer:

4.2 J

Explanation:

Specific heat capacity: This is defined as the amount of a heat required to rise a unit mass of a substance through a temperature of 1 K

From specific heat capacity,

Q = cmΔt.............................. Equation 1

Where Q = amount of energy absorbed or lost, c = specific heat capacity of water, m = mass of water, Δt = Temperature rise.

Given: m = 1 g = 0.001 kg, Δt = 1 °C

Constant : c = 4200 J/kg.°C

Substitute into equation 1

Q = 0.001×4200(1)

Q = 4.2 J.

Hence the energy absorbed or lost = 4.2 J

What is, by far, the most abundant component of Earth’s atmosphere?

Serjik [45]

Answer:

Molecular Nitrogen

Explanation:

Earth's atmosphere is a mixture of several gases in their molecular form . The most abundant of them is the element nitrogen. 78% of it is nitrogen and the rest that follow are Oxygen, Carbon dioxide and a mixture of other gases like Neon, Helium, Methane, Water vapor. hen the air is dry, argon is the third most abundant element in the earth's atmosphere.

As the height above the earth's surface increases, the air molecules decrease.

CHEGG 42 mT magnetic field points due west. If a proton of kinetic energy 9 x 10-12 J enters this field in an upward direction,

alexdok [17]

Answer:

The magnitude of the Force is $F = 697 *10^{-15}N$ and the direction is South

Explanation:

From the question we are told that

The magnetic field point due west and since East point toward the positive x -axis $(i)$ then this magnetic field would be mathematically represented as

$\= B = 42(-i)mT = 42*10^{-3} (-i) T$

Now from the question we are told that the kinetic energy is

$KE = 9*10^{-12}J$

Now this kinetic energy can be mathematically represented as

$KE = \frac{1}{2}mv^2$

Where m is the mass of proton which has a general value of

$m = 1.67*10^{-27}kg$

Now making the subject of the formula

$v = \sqrt{\frac{KE}{0.5 * m} }$

Substituting values we have

$v = \sqrt{\frac{9*10^{-12}}{0.5 * 1.67*10^{-27}} }$

$= 10.37*10^7m/s$

Now from the question we are told that proton is moving upward which is in the positive z direction so the velocity of the proton would be in the positive

So the velocity would be

$\= v = 10.37*10^{7} \r k \ m/s$
