Answer:

  • Oxygen
  • The body cells
  • Producing energy

Explanation:

We breathe in oxygen from the external environment. Oxygen passes into our lungs and is passed into the blood capilaries.  Here it is carried to all the cells throughout the body.

It diffuses into the cells and is necessary for the final stages of energy production by aerobic respiration. Therefore, it is necessary for powering all cellular processes.

Answer:

The correct answer is BB genotype and BO genotype.

Explanation:

The human blood system or ABO system shows codominance due to the multiple alleles. That means three different alleles for human blood type are present are IA, IB, and i. For easy understanding can be stated as A (for IA), B (for IB), and O (for i).

If someone has blood type B could have a genotype of either BB or BO because of the dominance of B allele on O where is If A allele present with B allele it would show co-dominance.

Shtirlitz [24]

Answer 1,2,3,4:

As both are heterozygous therefore Male genotype will be (BbEe) and the genotype of female will be (BbEe). While both will have the phenotype black.

Parent Genotype

Male X Female

BbEe X BbEe

Possible gametes from Parents

Male X Female

BbEe X BbEe

(BE) (Be) (bE) (be) X (BE) (Be) (bE) (be)

...

F1  generation will have following genetypic ratio

Black Labrador = 9  = B_E_

Brown Labrador = 3  = bbE_

Yellow Labrador = 3  = B_ee

Yellow Labrador = 1  = bbee

Furthermore, the phenotypic ration will be

Black Labrador = 9

Brown Labrador = 3

Yellow Labrador = 4
