Answer:
B, E are true
Explanation:
The process of respiration produces energy for organisms by combining glucose with oxygen from the air. During cellular respiration, glucose and oxygen are changed into energy and carbon dioxide. Therefore, carbon dioxide is released into the atmosphere during the process of cellular respiration.
A is false because respiration also happens in plants and is best at night (light not present)
B is true because during the reaction co2 is produced as waste
C is false because co2 is a waste product not a reactant
D is fals because o2 is a reactant not a product
E is true because the whole point of respiration to to produce energy (ATP)
F is false because this occurs in plants aswell
Answer:
1. 1/2
2. 1/2
3. 1/4
Explanation:
Let the allele for freckles be A or a while that of dimples be B or b.
A person without freckles but heterozygous for dimples = aaBb
A person who has freckles (whose mother has no freckles) but no dimples = Aabb
aaBb x Aabb
Offspring
4 AaBb - freckled and dimpled
4 Aabb - freckled and non dimpled
4 aaBb - non freckled and dimpled
4 aabb - non freckled and non dimpled
1. <em>Probability that the parents will have a dimpled child</em> = 8/16 or 1/2
2. <em>Probability that they will have a child with freckles</em> = 8/16 or 1/2
3. <em>Probability that they will have a child with freckles and dimples</em> = 4/16 or 1/4
