Answer:
The correct answer would be -
Punnett square is given below and on the base of the result of Punnett square, Millie should mate with <u>Denver</u> to get three different colors of puppies.
Explanation:
The question says that Millie has a genotype BB*, which is a combination or heterozygous condition of dark brown allele B and white allele B*, now cross with Denver (light brown color):
Cross 1:
B B*
B BB BB*
B* BB* B*B*
the results is : 25% dark brown, 50% light brown and 25% white.
cross 2: with Charley (white color)
B B*
B* BB* B*B*
B* BB* B*B*
there is only white and light brown puppies produced
Thus, the correct answer is - Denver.
Answer:
During photosynthesis, plants capture light energy from the Sun to break weak bonds in reactants, such as carbon dioxide and water, and form carbon containing molecules, such as glucose. The carbon containing molecules can then be used:
✓ to assemble larger molecules, such as DNA, proteins, and fats.

Answer: The skin of the animal will be lighter in shade.
Explanation:
The skin of the animal has genes which is responsible for producing darker shade of skin or pigmented skin.
If the gene for the darker skin or pigmented skin is not expressed then the effect of the gene on the animal skin will be that the skin will be fairer.
The skin of the animal depends on the gene that is expressed in his body. Based on this the skin color of the animal is decided.
Answer:
D
Explanation:
Every organism, even the almighty elephant, starts as a single cell. This single cell continually divides mitotically to form the adult organism. Contained in this single cell, is a DNA, coding for all proteins the adult organism will use. All these proteins will not be expressed at once, rather the cells keep dividing and as they divide they undergo gene expression to become specific types of cells. This process is called CELL DIFFERENTIATION.
Cell differentiation is the process by which dividing cells change their function or phenotypic type. Eventually, an organism with hundreds of different types of cells is formed by this process of cell differentiation.
After fertilization in animals (scorpion inclusive), a single celled zygote is formed. This zygote is totipotent i.e. capable of repeated division to form differentiated cells The cells of zygote then undergoes division and during the division, it becomes differentiated to form complex tissues and organs which make up the its body parts including its stinging tail. All cells emanate from the stem cells and becomes specialized as they mature.
N.B: the original mass of cells yet to undergo differentiation are known as STEM CELLS and they are contained in the zygote.
