If carbon dioxide levels in the blood increase, the ph will decrease, causing acidosis.
<span>
This happens because carbon dioxide forms carbonic acid, H2CO3 when it is dissolved in water. Carbon acid can lose two H atoms or protons. The loss of protons in a solution is what makes that solution acidic.</span>
I think the answer to this question would be letter A. Amphibians
Answer:
The age of fossils are in millions.
Explanation:
These fossils were present on the earth millions of years ago due to different and unique structure of the fossil. The fossil is present in the bottom of the middle layer indicates that the more age of fossil i.e. millions of years according to the law of superposition. This law states that in an undisturbed layers of rocks, the top layer is the younger layer than middle and bottom layers which is older than the top layer, so we can say that fossils from deeper layers are older than fossils from the top layers of rocks.
Answer:
A. The man's genotype is Bb. Phenotypes of the offsprings:- heterozygous brown-eyed- homozygous blue eyedGenotypes of the offsprings:- Bb- bbb. The blue is recessive, so the woman's genotype is bb. It is impossible for her to have B because it is dominant over b.c. The woman can only produce bb or blue-eyed.d. The man's genotype is Bb. It is impossible for him to produce an offspring with blue-eyes if his genotype is BB.e. The man can produce Bb or brown-eyed and bb or blue-eyed.
