Answer:

To find out the impact of environment on the physical structure of lizard and natural selection.

Explanation:

Ecologists conduct an investigation on the survival of a species of lizards in order to study the impact of environment on the physical body of lizard and natural selection. The ecologists find out that environment has direct impact on the body structure of lizard. Those lizards that spend more time on the ground, have longer legs in order to run fast, while on the other hand, species that lives in the trees usually have shorter legs in order to easily climb on the trees so these body structure helps them in survival and movement.

vlabodo [156]

Answer:

The mRNA molecule will be synthesized running in the 5' to 3' direction.

Explanation:

From the DNA sequence:

5'-ATCGTACCGTTA-3'

3'-TAGCATGGCAAT-5'

mRNA sequence is

5'-AUCGUACCGUUA-3'

Amino acid sequence will thus be:

Ileu-val-pro-leu.

Please help!!!! very confused pt 2

Schach [20]

Answer:

If the genotype of the parents are Iᵃi and Iᵇi, then four type of offspring will be produced.The genotype of the offspring are, IᵃIᵇ, Iᵃi,Iᵇi, and ii.

Explanation:

IᵃIᵇ = As the alleles are co-dominant in nature, so both type of alleles are expressed. The blood group will be AB. So, both A and B type of antigen will be found in plasma membrane of RBC.

Iᵃi= In this type of genotype only A type of antigen will be expressed in the membrane of RBC. The blood group will be A type.

Iᵇi= In this type of genotype only B type of antigen will be expressed in the membrane of RBC. The blood group will be B type.

ii= This is a recessive type of genotype. So, no antigen will be found on the membrane of the RBC. And the blood group will be O type.

The offspring's ratio will be 1:1:1:1.
