Answer:

C. IBIB

D. IBiO

Explanation:

The blood group system comprises of three different kind of alleles, iA, iB, IO. As we know that a person gets two alleles for both traits, one from father and one from mother, and based on that a person gets its blood group. IA and IB are dominant to IO.

So, if a person has genotype IAIO he will have blood group A and if he has genotype IOIB he will have blood group B because A or B are dominant to O.

However, if a person has blood group O it means that he has genotype IOIO.

So, in this diagram we see that Eric has blood type O, which means that his genotype will be IOIO.

The Eric's mother Melissa has blood group B, which means that she can either had genotype IOIB and IBIB respectively.

Similarly, Eric's grandmother Tricia has genotype B which means that she can have genotype both IOIB and IBIB respectively.

Therefore, both C and D are correct options.

How does the phenomena of survive of the fittest relates to peppered moth simulation?

IgorC [24]

Peppered moth stimulation is an experimental setup that show the behavior of moth in relation to their environment. The objective of the setup is to stimulate changes in moth population as a result of pollution and predation.
Peppered moth stimulation relates to the survival of the fittest because the moth with the most adaptive ability will be able to survive despite the negative forces in the environment. The bright colored moth was able to survive the pollution in the environment and retains its colour while the black coloured moth change its colour to black due to the pollution int the environment.

Answer:

UGU UAU AUC GAA AAC UAA

Explanation:

Hello There!

These are the transcription pairings

Adenine (A) to Uracil (U)

Thymine (T) to Adenine (A)

Cytosine (C) to Guanine (G)

Guanine (G) to Cytosine (C)

So given the DNA strand ACA ATA TAG CTT TTG ATT

We pair each nucleotide with its matching nucleotide (parings are provided above)

A to U

C to G

A to U

T to A

A to U

T to A

A to U

T to A

A to U

G to C

C to G

T to A

G to C

A to U
