Hey!
The correct answer is A.1. We know this because any good and controlled experiment will only be successful if one thing and one thing only changes. If there were two or more variables changing, then it’d be hard to collect accurate data and correct/confirm the hypothesis.
I hope I helped!

A.1 is correct because only one thing is changing and if you would change more it wouldn’t be as easy to get your data

A population of 100 rats was analyzed for their genotype at the isocitrate dehydrogenase locus. There are two alleles (R and S)
goldfiish [28.3K]

Answer:

Yes, this population lies in Hardy-Weinberg equilibrium as it follows both the principles of Hardy-Weinberg.

Explanation:

Here ,

f(A)= p=0.575

f(B)= q=0.425

As per the first principle of hardy Weinberg, the sum of all the alleles at the locus must be equal to 1.

Thus,

p+q=1\\0.575+0.425 = 1\\1=1\\

Also, as per the second equation of Hardy Weinberg's equation-

p^{2} + q^{2} +2pq =1

(0.575)^2+2(0.575)(0.425)+(0.425)^2=1\\0.3306+ 0.48875+ 0.180625=1\\1=1\\

Hence, this population lies in Hardy-Weinberg equilibrium as it follows both the principles of Hardy-Weinberg

You want to estimate the number of canvas backs (a type of duck) at the Sacramento Wildlife Refuge. In two days you capture 200
Vsevolod [243]

Answer:

Option A 400 individuals

Explanation:

Using this formula, we can estimate the population size of the canvas backs as this is a capture-recapture method.

N = (MxC) / R

Where N = estimated Number of individuals in the population

M = number of individuals captured and Marked = 200

C = total number Captured the second time (with and without a mark) = 200 and

R= number of individuals Recaptured (those with a mark) = 100

Thus, we have

N = (MxC) / R

= (200 x 200) / 100

= (40,000) / 100

= 400 individuals.

My homework says chicken has more protein carrots, what dors that mean?
nataly862011 [7]
Meats, beans and other foods like this are considered protein foods. It means that the chicken has amino acids that your body needs to survive. That's why it can be harder for vegans to find things to eat. Carrots may be healthy for you but they don't contain the amino acids that your body needs.
