Answer:

The correct answer is- tunica media

Explanation:

Tunica media is a thicker arterial wall layer which is mostly made up of smooth muscle cells. It forms the middle layer in blood vessels. Due to having a large amount of smooth muscle cells, these arterioles play an important role in regulating the flow of blood between arteries and capillaries.

They regulate blood flow by constricting and dilating the blood vessels. This regulation is important for the efficient transport of gases and nutrients when reaches the capillary bed. So the correct answer is tunica media.

Where did strep throat originate from?
Dafna11 [192]
Strep throat is the worst kind of illness you could ever get in my opinion. Your throat would burn all day, and you cannot swallow as easily. Yuck! It originated in China, because it spread quickly through a large population, because of bacteria in the tonsils.

likoan [24]

Answer: Hello your question some missing data attached below is the complete question

answer:

P( first child having PKU )  0.25 ≤ x ≤ 0.5

Explanation:

The pedigree father has PKU ( pp ) ( From the top right )

pedigree mother = PP

The possible resultant progeny = Pp  

Resultant progeny marries non-carrier  ( Pp x PP ) = PP , PP, pP, pP

Hence B is either  ; PP ( non carrier ) or Pp ( carrier )

<em>From left</em>

one of the Resultant progeny = pp ( affected ). this simply means pedigree parents where both carriers or sufferers i.e. Pp or pp

Hence A is either ; Pp or pp

The probability of their first child having PKU

= PP x Pp = PP, Pp, PP, Pp ( probability = 0 in this case )

= Pp x Pp = PP, Pp, pP, pp ( probability = 1/4 * 100 = 25% )

= Pp x pp = Pp, Pp, pp, pp ( probability = 2/4 * 100 = 50% )

P( first child having PKU )  0.25 ≤ x ≤ 0.5

lets denote dominant Gene = PP,  recessive Gene = pp
