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
Answer: option D
The sodium potassium ion exchange move sodium and potassium in opposite direction in electrochemical gradients.
Explanation:
The sodium potassium pump is found in many animals plasma membranes and its moves the sodium and potassium ion in opposite direction across the plasma membrane with the hydrolysis of ATP(adenosine triphosphate) to supply the needed energy. It is an active transport process.

Explanation:
1. Human and apes are evolutionarily closely related based on the analysis of their DNA sequences.
2. Wings of bats and birds serve the same function and are analogous structure.
3. Comparative anatomy is the study of the similarities and differences in structures in similar species.
4. Fossils demonstrate that during the evolution of the whale, the whale moved from land to the sea.
5. The human tailbone and appendix are vestigial organs.
6. The homologous structures are structures that are similar in related organisms because they were inherited from the common ancestor.
7. Comparative embryology is the study of similarities and differences in the embryo of different species.
8. The forelimb of all the mammals has basic bone structure.
9. Scientists who find and study fossils are called paleontologists.
