Which pair of molecules are both compounds?

Biology
1 answer:
Tanzania [10]3 years ago
6 0

Answer:

The correct option is C. <u>CO2, H20</u> are both compounds.

Explanation:

Compounds can be described as substances which are produced when atoms of different elements join together through the formation of chemical bonds.

In the option C, both CO2 and H2O are formed by the atoms of different elements. Carbon and two molecules of oxygen join to form carbon dioxide. Hydrogen and two molecules of oxygen join to form H2O. Hence, the correct option is C.

Option A is false because H2 is a substance made up of atoms of same element i.e Hydrogen. Option B is false because N2 is a molecule made up of the same atoms of nitrogen. Option C is false because O2 is made up of the same oxygen atoms.

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
