Answer:by breaking down carbonic acid into carbon dioxide and water.
The carbon dioxide is expelled from the body
Explanation:the body is able to maintain a constant internal environment through hoemostatis.one of such control is the acid-base balance in the body.
It does this by regulating the amount of hydrogen ions in the blood.A low pH indicates an acidic condition and a high pH indicates an alkaline condition.
The human blood has a pH of 7.35---7.45.it is slightly alkaline and needs to keep this range constant.
The lungs and kidneys involved in regulating the body pH.
When there is excess hydrogen ion in the blood, bicarbonate ions combine with the hydrogen ions to form carbonic acid . this carbonic acid breaks down into water and CO2 .the co2 is expelled from lungs through gaseous exchange.
When the accumulation of acid in the blood is high,the pH drops below 7.35 and this is called respiratory acidosis.
When there is excess alkaline in the blood,the pH goes beyond 7.45 and this is called respiratory alkalosis.
Answer:
Atom, smallest unit into which matter can be divided without the release of electrically charged particles. It also is the smallest unit of matter that has the characteristic properties of a chemical element. As such, the atom is the basic building block of chemistry.
Atom: has equal number of +ve charge (protons) and -ve charge electrons and hence atom has charge.
Neutrons (having no charge) and protons are present in nucleus. Electrons keep revolving around the nucleus in different shells.
Answer:
The correct options is B.
Explanation:
Evolution has to do with the changes that occur in a particular population of organism as a results of environmental changes and other pressure that the population is exposed to and how the organism adapt to counter the changes.
Out of all the options given in this question, the individual that is most likely to be successful in an evolutionary sense is the one describe in option B. This is because, the organism has a short life span of five days and it left behind ten children that are capable of reproducing. Evolution is a process that occur over a long period of time. So, if it an environmental change occur in the environment where the organism lives, it will be easier for the new generation and the subsequent generations of the organism to adapt to the change.
Those organisms that have long life span will not be able to adapt as easily as the organisms in options B because it will take many years and many generations for them to do that.
I believe it’s 50%, it’s either 50% or 75%
