Molecules are defined as the smallest particles of a chemical compound or an element, and are made up of atoms. Cells are made up of semi permiable membranes that only allow selected materials to move in or out of the cell, therefore due to the big size of molecules compared to atoms the membrane doesn't allow their passage in the cell. Therefore the cell doesn't allow most molecules to diffuse passively to the cell. Secondly, molecules that can enter the cell requires specific carriers carriers that will enable entry of small molecules in the cell.
Answer:
Archaea
Eubacteria
Explanation:
Both the kingdoms archaea and eubacteria comprise of prokaryotes yet there are some differences present between the two kingdoms.
The archaea have a distinct evolutionary history as compared to the eubacteria. The cell wall of archaea is made up of Pseudo-peptidoglycan where as the cell wall of eubacteria is made up of peptidoglycan or lipopolysaccharide. Interior membranes cannot be found in the archaea but are present in the eubacteria.
Answer:
Congestive Heart Failure.
Explanation:
Congestive heart failure may be defined as a type of the chronic condition that might affect the pumping of the heart muscles. The fluid gets accumulated in the heart.
The congestive heart failure cannot be easily marked in youngsters but can be marked easily in the old persons. The individual feels difficulty in breathing and may also suffer from the tachycardia. Excessive sweating and change in the nail color is common in severe heart failure.
Thus, the correct answer is option (D).
Answer:
here is your answer
Explanation:
Global warming is primarily caused by emissions of too much carbon dioxide (CO2) and other heat-trapping gases into the atmosphere when we burn fossil fuels to generate electricity, drive our cars, and power our lives. Thus, as we continue to emit these gases, their atmospheric concentrations build up over time
