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!!
the common name for this is called Bryophyta
Answer:
Tributary-river-river system
i think this is the answer
Explanation:
It's actually A. Vertebrate have a hard out shell.
Archaea differ from bacteria in that archaea lack peptidoglycan.
<h3>
What about archaea and bacteria?</h3>
- Although archaea lack internal membranes, they do have a cell wall and swim by using flagella.
- The difference between bacteria and archaea is that bacteria have an ester-linked cell membrane, while archaea have an ether-linked cell membrane.
- Organelles and other internal membrane-bound structures are not present in the cells of bacteria and archaea.
- In contrast to eukaryotes, bacteria and archaea do not have a nucleus that separates their genetic material from the rest of the cell.
- Similar to Eubacteria, Archaea have a polysaccharide and glycoconjugate-rich cell wall.
- The strong cell borders that archaea form despite not having peptidoglycan make them resistant to high internal osmotic pressure.
