Alborosie

DNA replication

After the process of DNA replication occurs, each daughter cell receives an exact copy of the parent cell's DNA.

DNA replication is a biological process by which a DNA molecule divides to produce two copies of itself during cell division. DNA replication takes place in all living organisms. During DNA replication, an enzyme known as helicase separates the double helix structure of the DNA molecule into two separate strands which serve as templates for making the new strands of DNA.

An organism has two types of cells: diploid somatic cells and haploid gametes. How does this organism reproduce? A. Sexually B.
kenny6666 [7]

Answer:

A. sexually

Explanation:

The organism has haploid gametes. Human sex cells (egg and sperm cells) contain a single set of each chromosome, making them haploid. During fertilization, the organism acquires a set of chromosomes from each parent, making it a diploid (two sets of each chromosome) zygote.

Hope this helps.

The lungs remain inflated because ___________.a. intrapleural pressure is exactly equal to atmospheric pressure b. intrapleural
kkurt [141]

Answer:

Option C,  Intrapleural pressure is less than intrapulmonary pressure

Explanation:

During inspiration, the air enters the lungs due to lower pressure in the intrapulmonary or intra-alveolar  than the atmospheric pressure. During quite respiration, the intrapulmonary pressure reduces to a pressure that is 3 mm Hg lower than that of atmospheric pressure. During quiet expiration, the intrapulmonary pressure rises up to a pressure that is 3 mm Hg higher than that of atmospheric pressure. This leads to lack of air in the intrapleural space thereby producing intrapleural pressure which is lesser than that of intrapulmonary pressure.  

This difference in pressure (i.e higher pressure with in the lungs than the atmosphere)  causes lungs to remain attached to the chest wall and hence looks inflated.  

Hence, option C is correct
