A. A and B

B. B and C

C. B and D

D. A and D

<h2><u>Answer:</u></h2>

The correct answer is option D.

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

Alveoli is defined as the unicellular thickened sac like structure of lungs which helps in exchange of gases in lungs. The exchange membrane of lungs comprise of three structures -

A. The epithelium cells of Alveoli,

B. The basement membrane of alveolar epithelium,

C. The endothelial layer of blood capillary.

The red blood cells described here won't cause any problems to the diffusion of gases from alveolar cavity to blood. The structures mentioned here as the type 2 cells of Alveoli which secrete lecithin, a surfactant which releases the surface tension of Alveoli. This compound prevents the Alveoli from collapsing and helps in diffusion of gases. The other structure mentioned here as D are the alveolar epithelium which is the unicellular thickened membrane of Alveoli, helping in gaseous exchange.

The Salinas River empties into the Pacific Ocean and cuts into the continental shelf , thereby forming which of the following fe
katrin2010 [14]
The continental shelf is a gently sloping feature found at the edge of a continental landmass going seaward from the coast. Rivers that empty into the sea can produce currents that are strong enough to erode the material that builds the shelf. When this occurs channels or submarine canyons are formed. These canyons are deep and dark as no light can penetrate these regions. The canyons often lead out to sea towards the edge of the shelf.

A(n) __________ is created when sperm meets egg and contains all DNA necessary to create a person.
miss Akunina [59]

Answer : The correct answer for the blank is -

a. zygote.

A zygote can be described as a diploid cell that is produced by the fusion of gametes (from each parent such as egg and sperm). The process of fusion is called fertilization and zygote is also called fertilized ovum/egg.

Zygote undergoes multiple rounds of proliferation (cell division through mitosis) and ultimately differentiates to produce the highly advanced stage, fetus (which is fully developed baby).

Thus, a zygote is formed when sperm meets egg and contains all DNA necessary to create a person.
