andrezito [222]
The model attached represents facilitated transport, which is answer choice D. In the model, there are protein channels, which allow molecules to pass through them if they're too large to fit through the aquaporins (making diffusion an incorrect answer.) We can eliminate active transport since ATP isn't used to control transport, and we can eliminate endocytosis as it is a form of active transport. The remaining answer would be facilitated transport, which is a form of passive transport. Hope this helps! :)

lara31 [8.8K]

Answer:

<h2>A) Yes, 12 mu</h2><h2>B) AaWw</h2><h2>C) 0.25%</h2><h2 />

Explanation:

As given,

Allele A for  blue anthocynin.

aa for yellow kernel;

at  second locus;

W produce smooth kernel,

ww for wrinkled kernel;

Parents as given are:  AaWw and aaww

Progeny are:

blue smooth ( AaWw)= 1447;

blue wrinkle (Aaww)= 169;

yellow smooth (aaWw)= 186;

yellow wirnked (aaww)= 1510

a)

Recombinant progeny are  169+ 186= 355

non- recombinant progeny are = 1447+ 1510= 2957

so recombination frequency (RF)= 346/2957×100= 12.0054%

So a and w are linked genes.

They are 12 mu far away from each other.

b) Blue smooth parent= AaWw.

c) Aaww crossed with  aaWw

progeny are= AaWw, Aaww, aaWw, aaww,

They all are produced in same proportion =0.25% or 1/4.

Is glucose aversion a learned response, or is it inherited?
Keith_Richards [23]
<span>Rather than being learned, glucose aversion is inherited as an autosomal incompletely dominant trait, which appears to he controlled by a single major gene. This was discovered through a study done on cockroaches, some were fed regular bait while some were fed bait laced with glucose. Through time they began to avoid the glucose.</span>
