Carbon dioxide is a waste product of cellular respiration
See if any of the organisms lived before the others by measuring the age
of their fossils using some means, like radioactive dating.
Answer:
A mountain chain of sedimentary rock may form as a result of a convergent boundary of two continental crusts
Explanation:
Mitochondria, this is because the function of the mitochondria is:
To release energy OR
To produce ATP (both are correct, so whichever you remember easier)
1) Data:
dominant allele- A
recessive allele- a
Heterozygotic: Aa (only carries the allele)
Homozygotic recessive: aa (expresses the disease)
Homozygotic dominant: AA (doesn't carry or expresses the disease)
2)The first cross between Jim and his first wife originated a offspring with
<span>cystic fibrosis</span>. That offspring has the genotype aa and for that to happen both parents need to be a least carriers or express the disease. The exercise rules out the second case, which makes Jim a carrier.
3)Now between Jim and Martha:
From the previous step, we already found that jim is a carrier and the exercise also tells us that Martha is one too. So, their genotype is: Aa.
The cross: Aa x Aa
The probability:
1/4 aa = 25%
2/4 =Aa
1/4 - AA
the probability of having a <span>baby with cystic fibrosis is 25%</span>
