Your answer would be: A. because scientists use what they have to create a theory, a theory is pretty much an educated guess is what a teacher would say, the theory would need to have evidence in order for it to be an educated guess. The scientist would have to come up with an explanation in order for the theory to work, or be an educated guess.

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.

Why would competition be considered a limiting factor within a ecosystem
raketka [301]

Answer

The main reason being the amount of food available.

Explanation:

Think of it this way:

If an animal is trying to find food but another species is looking for the same prey then its going to be increasingly difficult for the species to find prey and if there's not enough of the prey species then the population of the predator to go down.

That is why its considered a limiting factor.

givi [52]

The molecular biology technique of reverse genetics can be useful for determining the function of a gene.

<h3>What is reverse genetics?</h3>

Reverse genetics is method use in molecular biology to determine gene function in an organism

The procedure in reverse genetics involves modifying or certain nucleotide sequences in the DNA coding for a functional gene and then observing changes to the phenotype of the organism brought about by the modifications.

Therefore, reverse genetics can be useful for determining the function of a gene.

What is a type of emigration where offspring move<br> away from their parents.
Bas_tet [7]

Answer:Dispersal

Explanation: This refers to offspring moving away from their parents. This prevents the offspring from competing with the parents for resources such as light or water. For example, dandelion seeds have “parachutes.” They allow the wind to carry the seeds far from the parents
