Answer:

Answer is coronary angioplasty.

Explanation:

The coronary angioplasty is a kind of procedure that involves the insertion a balloon- filled catheter into the blood vessel for the purpose of increasing blood flow.

Medical imaging is use in guiding the catheter to the targeted site. And the use of a metal mash tube known as stent may be adopted or not.

The coronary blockage prevent the flow of blood to the heart.

Note that, this procedure is considered to be better in some aspects to coronary artery bypass grafting [CABG].

This is because. it is not a surgery like CABG,, has fewer risks and a small cut.

You are studying a population of snapdragon plants on Membata Island. In snapdragons, the dominant allele CR encodes red flowers
fredd [130]

Answer:

we will know that the allelic frequencies are for R 0.95 and r 0.05

Explanation:

We know that the population is in Hardy-Winberg equilibrium, we deduce the following formula:

p + q = 1

p2 + 2pq + q2 = 1

data

R: red flower allele

r: allele blor blanca

p would be equal to the allelic frequency R

q will be equal to the frequency allelic r

2p = RR

2q = rr

2pq = Rr

If there are 25 white flowers in 1000 plants, their frequency will be:

2pq frequency of the Rr genotype

white flower = 25/10000 = 0.0025 = rr = 2q = 0.0025

we deduce that q is equal to 0.05

we replace the data with the previous formula

p + q = 1

p = 1-0.05

we get as a result

  p = 0.95

if p = 0.95 and q = 0.05

we will know that the allelic frequencies are for R 0.95 and r 0.05
