Answer:
75% chance of having four normal phenotype children without albinism.
50% chance of having four children who are carriers of the gene with normal phenotype.
Explanation:
Albinism results from an autosomal recessive gene. In order to solve this problem we have to draw a punnet square and figure out the genotypes of the parents. So with the genotype of the parents both parents have to be carriers of the trait since it is an autosomal recessive trait.
Genotype of female I-1 = Aa
Genotype of male I-1 = Aa
PARENTS A a
A AA Aa
a Aa aa
75% chance of having four normal phenotype children without albinism.
50% chance of having four children who are carriers of the gene with normal phenotype.
25% chance of having children with albinism.
Answer:
D. they are unicellular
Explanation:
unicellular organisms are not part of the kingdom animalia .Animalia consists of aves(birds),amphibians,reptiles,mammals and so on and all these organisms are multicellular that is having more than one cell.
It is referred to as Xylem tissue.
Answer:
<u>Passive</u> transport
Explanation:
There are two ways molecules can get in and out of the cell. These processes are called Passive and Active transport.
Passive transport is the movement of molecules and materials from high to low concentration. No energy is needed for this process because it happens naturally.
This is in contrast to what Active transport is, where energy is needed because it moves the molecules or materials against the concentration gradient where they move from lower to higher concentration.
The large, flat bone extending from the middle of the back upward to the joint where it attaches to the clavicle is called the scapula.
Clavicle is the collar bone. It is a long and thin bone with slight curve that works to connect the arms to the body. It is a part of the shoulder. It allows free movement of the shoulder. The clavicle is attached with the sternum through the sternoclavicular joint.
Scapula is a triangular-shaped bone. it is present at the upper back portion. It us surrounded by various muscles that allow the free movement of the shoulder. The types of motion, scapula helps in are: protraction, retraction, elevation, depression, upward rotation, and downward rotation.
