Answer:

Nitrogen is important to life because it is a key part of amino and nucleic acids. These bacteria are known as nitrogen-fixing bacteria. These organisms convert nitrogen in the soil to ammonia, which can then be taken up by plants.

A plastic bottle contains 32.5 L of gas at a pressure of 45.7 kPa and

Monica [59]

Answer:

Final pressure, P2 = 362.26 kPa

Explanation:

Given the following data;

Initial volume = 32.5 Liters

Initial pressure = 45.7 kPa

Final volume = 4.1 Liters

To find the final pressure, we would use Boyle's law;

Boyles states that when the temperature of an ideal gas is kept constant, the pressure of the gas is inversely proportional to the volume occupied by the gas.

Mathematically, Boyles law is given by;

$PV = K$

$P_{1}V_{1} = P_{2}V_{2}$

Substituting into the equation, we have;

$45.7 * 32.5 = P_{2} * 4.1$

$1485.25 = 4.1P_{2}$

$P_{2} = \frac {1485.25}{4.1}$

$P_{2} = 362.26$

Final pressure, P2 = 362.26 kPa

The complex of dna and protein that makes up a eukaryotic chromosome is properly called __________.

victus00 [196]

The complex of DNA and protein that makes up a eukaryotic chromosome is properly called <u>chromatin .</u>

<u></u>

Chromatin is a complex of DNA and proteins that forms chromosomes within the nucleus of eukaryotic cells.

What is the chromatin and its function?

To create chromosomes, chromatin fibers are coiling and condensing.
Numerous cellular functions, including DNA replication, transcription, DNA repair, genetic recombination, and cell division, are made possible by chromatin.

What is chromatin in cell?

Chromosomes in eukaryotic cells are made of chromatin, a compound of DNA and proteins.
Nuclear DNA is extremely compressed and wrapped around nuclear proteins in order to fit inside the nucleus; it does not exist as free linear strands.

Where is chromatin found?

Chromatin is a genetic material or a macromolecule comprising DNA, RNA, and associated proteins, which constitute chromosomes in the nucleus of a eukaryotic cell.
This chromatin is located within the cell nucleus.

saul85 [17]

Answer:

rod photoreceptors

Explanation:

The retina of the eye has 2 types of sensory receptors or photoreceptors. They are the rod cells and the cone cells. The rod cells mostly found at the outer edge of the retina of the eye, which are numerous and more sensitive compared to the cone cells. The cone photoreceptors are found in the macula.

The rod photoreceptors are responsible for night vision mainly and function in dim light or less intense light, while the cone receptors are responsible for color sensitivity.

The rod photoreceptors are responsible for processing his ability to see objects in the darkness.
