<span>One way social behavior increases survival in humans is the increased security from attackers and other physical threats. Another is that social cooperation increases the likelihood for success in the gathering of required resources for survival such as food. It also increases the chances of survival of offsprings due to the cooperative raising of the kids within the social grouping.</span>

Juan is working with a darkfield microscope with a numerical aperture (NA) of 1.25, Ali is working with a brightfield microscope
Alex

Answer:

Juan

Explanation:

Given the information from the question. We need to find out which person will get the best resolution and the reason thereafter. Since we know that the resolution is directly proportional or relative to N (A). Based on the information provided .Juan will have the best resolution due to higher N (A). Therefore, the correct answer is Juan.

A gene has 2 alleles, R &amp; B, List the possible genotypes? I also need help with questions 5, 6, 7 and 8 please help! Pls loo
irakobra [83]

Answer:

5.) The possible genotypes should be: RR RB BB ( if the could for the same proteins)

6.) Frequency of R: 0.5

7.)Frequency of R: 0.5

8.)Frequency of R: 0.375

Explanation:

5.) If R and B code for the different forms of the same protein then they are only a few possible out comes

6.) First calculate the total alleles in population

allele R= 40

Allele B=40

total allele = R+B= 40+40

=80

Now to find allele R frequency is:

(Total R alleles) / (Total allele in pop)

40/80=

0.5

7.)Calculate the total alleles

Alleles from for R

RR= 10

R=10x 2= 20

Multiply the value by 2 because there are 2 R alleles present in

RB=20

R=20

Number doesn't change there is only 1 R allele

Total R=20+20

=40

Alleles For B

BB=10

B=10×2

=20

Same thing here, two B alleles together so multiple by 2

RB=20

B=20

Total B= 20+20

=40

Total alleles in pop add

40+40

=80

Frequency of R

Total of R/Total Alleles

=40/80

=0.5

8.)Repeat the same thing in 7 but use different numbers

RR=10

R=10x2

=20

RB=10

R=10

Total R= 20+10

=30
