Describe how alveoli are adapted for gas exchange( 4 marks)​
SashulF [63]

Answer:

they give the lungs a really big surface area. they have moist, thin walls (just one cell thick) they have a lot of tiny blood vessels called capillaries.

The walls of the alveoli are only one cell thick. This makes the exchange surface very thin - shortening the diffusion distance across which gases have to move. Each alveolus is surrounded by blood capillaries which ensure a good blood supply.Adaptations of the alveoli:

Thin walls - alveolar walls are one cell thick providing gases with a short diffusion distance. Moist walls - gases dissolve in the moisture helping them to pass across the gas exchange surface. Permeable walls - allow gases to pass through.

Which term(s) in the van deemter equation does(do) not affect the plate height?
Andru [333]
In the van deemter equation, plate height (H) = A + B/u+ Cu.
So, A, B, U, and C affects the plate height. A is the eddy diffusion term, B is the longitudinal or ordinary diffusion term, C is the nonequilibrium or resistance to mass transfer coefficient, and U is the linear velocity.

<h3>What is smallpox?</h3>

Variola major or Variola minor are the two virus strains that cause the contagious sickness known as smallpox. The variola virus (VARV) agent is a member of the genus Orthopoxvirus. The World Health Organization confirmed the illness's universal eradication in 1980 after the last naturally occurring case was diagnosed in October 1977, making polio the only human disease to have achieved this feat.

Fever and vomiting were among the disease's earliest signs. This was followed by the development of mouth ulcers and a rash. The skin rash developed into the typical fluid-filled blisters with a dimple in the middle over a period of days. The scars were left after the lumps scabbed over and dropped off. People could contract the illness from contaminated things or from one another. Prevention is through the vaccine for smallpox.

According to the pedigree chart, which statement MUST be true?
dem82 [27]

Answer:

<h3>A) Only Male offspring can inherit the disease. </h3>

Explanation:

As per the pedigree chart, only the males are shown as affected by the disease. Thus, it must be a sex-chromosomal inheritance, expressed in the Y chromosome or the male chromosome.  

As the females in the family are unaffected, hence the mother in the original parental generation cannot be a carrier.

It is likely that the father from the original parental generation might be the carrier.

As there are affected individuals in both the generation after the original parental generation ( the last generation having two more affected males), the statement that the chances of inheriting the decease with each successive generation is not true.
