Explanation:
Plants release water through transpiration while cohesion is responsible for moving more water throughout the xylem. When the water evaporate through the stomata, more water is pulled from roots into stem and eventually reach the leaf this process is called transpiration-cohesion theory.

Explanation:
I've had this question before got it right.
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!!
Answer:
Nucleoid
Explanation:
Prokaryotes are unicellular organisms that lack organelles or other internal membrane-bound structures. Therefore, they do not have a nucleus, but, instead, generally have a single chromosome: a piece of circular, double-stranded DNA located in an area of the cell called the nucleoid.
Answer:
The characteristics that define liver diseases within bryophytes are:
They are terrestrial plants unlike Charophytes that are aquatic.
There is development of an embryo that gives rise to a diploid multicellular sporophyte.
