Answer:

<h2>Its true!!</h2>

Explanation:

Actually the haemoglobin molecule consists of 2 parts, the haem which is a prosthetic group and the other globin which is a protein. So the haemoglobin as is a protein so, is arranged in quaternary structure of protein which contains 4 subunits. The subunits depend upon the organism whose haemoglobin is being talked about. So the normal haemoglobin found in red blood cells contains 2 alpha subunits + 2 beta subunits. At the centre of each subunit there is the haem part attached. To the centre of haem the Fe3+ ion are present which actually attaches to 1 Oxygen molecule. So as 4 subunits are present and each subunit has 1 Fe3+ ion, so total 4 Oxygen molecules can bind to the 1 Hb molecule!!

Which of these statements best describes a similarity between photosynthesis and dissolving in the sea?
Mama L [17]

The correct answer is D. Both absorb carbon dioxide from the atmosphere.

The process of photosynthesis is carried out using atmospheric carbon dioxide by green plants. Many gases including carbon dioxide are dissolved in seawater. Some of the carbon dioxide gas remains in dissolved state but most of the carbon dioxide is reacts with water to form carbonic acid. Dissolved gases in seawater make balance with atmosphere by mixing of the surface by wind and waves. Therefore, both photosynthesis and sea water take carbon dioxide from the atmosphere.

How does RNA differ from DNA?
Leona [35]
I think that the answer is C- "I RNA contains uracil and ribose." because it is the one that mostly makes sense and is the one that most shows the difference between RNA from DNA.

According to google: "Ribonucleic acid (RNA) is a polymeric molecule implicated in various biological roles in coding, decoding, regulation, and expression of genes. RNA and DNA are nucleic acids, and, along with proteins and carbohydrates, constitute the three major macromolecules essential for all known forms of life."

I hope this helped!
