What effect does rapid exhalation of CO2 during exercise have on the concentration of H2CO3 in the blood?
BARSIC [14]

If there is a constant loss of CO_{2}~(carbon~dioxide) the concentration of H_{2} CO_{3}~(carbonic~acid) will be affected and decrease since CO_{2} is a main component of H_{2}CO_{3}.


Hope it helped,

Decribe how hydrogen and oxygen form water
rewona [7]

Well, its a very simple process actually. Here is how it works;

When molecular hydrogen, also known as H2, and oxygen, also known as O2, are combined and are able to react together, energy is released and the molecules of the hydrogen and the oxygen. These can combine to form either water or hydrogen peroxide, depending on how the chemicals mix.

I hope I made your day a little easier,

Have a great day and happy Halloween!

Arden is making a pros and cons list about genetic engineering for a debate at school. Which part of her list is incorrect?
Soloha48 [4]

Answer:

The part of Arden's list that seems to be wrong is that genetic engineering can create organisms that survive in different environments (Pro 2).

Explanation:

Genetic engineering is a branch of genetics that introduces the use of technology to modify a living organism by introducing modified DNA into its original genome in order to improve its characteristics

The organisms subjected to changes by genetic engineering are called genetically modified organisms or GMOs, and can be stronger, longer-lived, more productive, or resistant to disease.

<em>Making a species resistant to any environment could cause it to develop in places where it could not live before, affecting the natural balance of an ecosystem to which it previously did not belong, so Pro 2 on Arden's list does not seem to be entirely beneficia</em>l.

an atom has 79 protons, 78 electrons and a mass number of 118. how many neutrons does this atom have​
igomit [66]

Answer:

39

Explanation:

Electrons weigh almost nothing, so their mass doesn't really matter for these types of problems. Just subtract 118-79 to find the remaining mass which is for the neutrons.
