In the lungs, oxygen diffuses into the blood and is loaded onto hemoglobin for transport. In the tissues, oxygen is unloaded fro

emmasim [6.3K]

Answer:

D. partial pressure of oxygen

Explanation:

Partial pressure refers to the force applied by an individual gas per unit area in a mixture of gases which is measured in mm of Hg. The partial pressure determines the movement of the gas molecule in the system.

In the given scenario, the oxygen transport through the blood along with other gases like carbon dioxide and other minute concentration but the gaseous exchange between the lungs and the blood, between the blood and the tissues depends on the partial pressure of the oxygen. The oxygen moves from the higher pressure to lower pressure therefore partial pressure is the determining factor.

Thus, Option-D is correct.

in eukaryotes, genetic material is packaged in the nucleus. which group accurately lists the levels of the packaging in order of

vredina [299]

The DNA molecules are often fitted into the nucleus through packaging into a compressed and compact structure. The group that accurately lists the levels of the packaging in order of increasing size are nucleotide, DNA duplex, nucleosome, chromatin, chromosome.

Chromosomal DNA is often packaged into a nuclei that is microscopic in nature through the help of histones.

In the DNA packaging inside the nucleus, the cells folds or wrap their DNA strands around scaffolding proteins to form a coiled condensed structure. The structure is known as chromatin.

The full question is below

Which one of the following MOST accurately lists the components in order of increasing size?

A. chromosome, chromatin, nucleosome, DNA duplex, nucleotide

B. nucleotide, DNA duplex, nucleosome, chromatin, chromosome

C. nucleotide, DNA duplex, chromatin, nucleosome, chromosome

D. nucleotide, nucleosome, DNA duplex, chromatin, chromosome

E. chromosome, nucleosome, chromatin, DNA duplex, nucleotide
