Answer:
The correct answer is - brown heterozygous Bb and blue eye bb.
Explanation:
In the provided question it is given that there are 20 babies born, 10 babies had blue eyes and 10 had brown eyes. As it is known that brown eyes are dominant over blue eyes, therefore, on the basis of this we can say that all blue-eyed babies have a bb genotype and as brown eyes are dominant traits babies must have at least one copy of the B allele which represents brown eye trait.
case1:
Parent 1 : bb
parent 2: BB
B B
b Bb Bb
b Bb Bb
there are 100% brown eye offspring so this is not the case
case 2:
Parent 1 : bb
parent 2: Bb
B b
b Bb bb
b Bb bb
here, 50% brown eyes and 50% blue eyes offspring produced thus, the parent trait will be brown heterozygous and blue eye.

Answer:
The folds or projections in the plasma membrane works to increase the surface area of the membrane by many-fold. As can be seen by the increase in certain values, there is a greater surface-area-to -volume-ratio which is indicative of the advantage that cellular processes take place more efficiently this way. Hence, it's favorable for the cells to have folds in its membrane, for instance the villi in the small intestine are finger-like projections that helps in efficient absorption of food into the bloodstream.
Hope that answers the question, have a great day!
Answer:
93 billion light years
Explanation:
The proper distance—the distance as would be measured at a specific time, including the present—between Earth and the edge of the observable universe is 46 billion light-years (14 billion parsecs), making the diameter of the observable universe about 93 billion light-years (28 billion parsecs).
Answer:
It would be=
14 protons -
17 electrons=
-3 :D
When you subtract protons from electrons, you get the electrical charge.
