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.

Suppose the cells of a tumor are idealized as spheres each with a radius of 5 mum (micrometers). The number of cells has a doub

loris [4]

Answer:

1044.3 days

Explanation:

Given,

Radius of sphere shaped cells of tumor $= 5$ micrometer

$1$ centimeter $= 10,000$ micrometers

Thus, radius of sphere in centimeters

$= \frac{5}{10,000} \\$

Volume of a sphere

$= \frac{4}{3} \pi r^{3}$

Volume of one cell of tumor

$\frac{4}{3} *(3.14)*(\frac{5}{10,000})^{3}\\= {5.23 * 10^{-10}$ centimeter cube

As we know ,

$N(t) = N(0) e^{-kt}\\\\k = \frac{ln2}{35}\\ k = 0.0198 day^{-1}\\$

Substituting all the given values in above equation, we get -

$0.2 = 5.23 * 10^{-10} * e^{-0.0198*t}\\t = 1044.3$ days

Two people die. one is in the Arctic and one is in the desert. which one will Decay faster and why?

Yakvenalex [24]

The body in the desert will decay faster because of the warm climate, unlike the arctic, which is cold. The body in the Arctic would be somewhat preserved for a certain amount of year because of sub-zero temperatures.

Hoped this helped.
