Answer: The correct answer is Grana.

Thylakoids is a system of membrane sacs, which is present in the chloroplast. These membranes are stacked to one another in the chloroplast and form a structure called as grana. The grana are connected to each other by simple membrane called as stromal lamellae. The light dependent phase of photosynthesis occurs in these thylakoid membrane.

Thus, the term that describes the stacks of thylakoid is Grana.

The correct answer is Grana.

Thylakoids can be defined as the system that surrounds the thylakoid lumen. Thylakoid are stacked on one another like coins in the chloroplast and forms the structure called as Grana.

The light dependent reaction of photosynthesis occurs in the thylakoid membrane.The grana are connected to each other by simple membrane called as stromal lamellae.

What does the respiratory system eliminate when there is an excess of hydrogen ions in the body?
qwelly [4]

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.

how could measure whether or not the chemical reaction that breaks down hydrogen peroxide is occurring
d1i1m1o1n [39]

Answer:

You could check the pH!

Explanation:

This is an idea, when you break down H2O2 (Hydrogen peroxide) you will be left with H2O (Water) and O2 (Oxygen gas). H2O2 theoretically would have a lower pH than water. Water has an average pH of around 7 while H2O2 will have a pH of about 4.5.

So theoretically to figure out if hydrogen peroxide is being broken down you can test for the pH. This is a very simply process, you just stick a little peice of litmus paper into the solution and immediatly it will change color to tell you the pH.
