It will cause vasodilation of blood vessels in the brain.

CO2 is one of the metabolic end products that can alter the tone of the blood vessels in the brain. High CO2 levels cause vasodilation, which may cause headache, whereas low CO2 levels cause vasoconstriction, which may cause lightheadedness. The statements included in the other options are incorrect effects.

kotegsom [21]
<span>However, these advancements that other people are talking about will not probably last for very long since much resources were used to exploit and overuse the natural resources we currently have. The question of what about the future populace who are significantly viable to live under this planet, 100 years from now? Isn't that claim sort of egotistical?
Exploitations lead to different global ecological changes like the occupation of the invasive species which can threaten an ecosystem and the biodiversity of the organism that exist in the present environment when the invasive species increase rapidly in number.

According to the geologic time scale, modern humans coexisted with dinosaurs.
marshall27 [118]

Answer:

FALSE

Explanation:

To coexist mean to exist (live) at the same time.

The dinosaurs disappeared about 66 MILLIONS years ago... that's a long time!

Humans first appear around 300 THOUSANDS of years ago.

As you see, we're not talking about the same scale of time at all, so there was never any encounter between a live dinosaur and a live human, except in the movies, that might be the reason we find them so cool. :-)

A man, joe, has classic hemophilia, an x-linked recessive disease. classify each person depending on whether or not joe could ha
MrRissso [65]
1-
First, i m going to explain how the disease is inherited.
Like it says in the question, hemophilia's gene is carried on the X chromosome and is recessive.
Females inherit two X chromosomes, one from each parent. They are: XX
Males inherit one X chromosome from their mother and a Y chromosome from their father. They are XY.

I'll represent with Xᵃ- when the chromosome has the disease's gene and with only an X when that chromosome is normal.

2-
If Joe has hemophilia is because the X chromosome that was inherited from the mother, came with the disease. Since men only have one X chromosome, the gene will be expressed.
However, this doesn't mean that the mother had the disease, she could be only a carrier with this genotype: XᵃX
(there is not enough information to be sure which one is she)

The answers:
3-
Maternal grandmother- COULD HAVE INHERITED
Like i said before, Joe's mother had a least one X chromosome with the disease's gene, and that came from either her father or her mother( joe's Maternal grandmother).
If it came from the grandfather, that means that he was hemophilic.
If it came from the grandmother, that means that she was a carrier or also had the disease. There is not enough info to be sure which genotype she has but either way, there is a possibility.

4-
Maternal grandfather- COULD HAVE INHERITED
Joe's mother had a least one X chromosome with the disease's gene, and that came from either her father( maternal grandfather) or her mother.
If it came from the grandfather, we can be certain he was hemophilic.He had the same genotype as joe which is: Xᵃ Y

5-
Paternal Grandmother and Paternal Grandfather- COULD NOT HAVE INHERITED.
In x-linked recessive diseases, fathers cannot pass it on to their son because they will pass the Y chromosome, not the X.
Joe's father gave Joe the Y chromosome and will not pass any X.
So, even if Joe's father and his side of the family had hemophilia, that wouldn't matter because either way, Joe will not be receiving any X chromosomes.
