Answer:
Following information are needed to classify an organism.
1. Unicellular or multicellular : First we have to see that from how many cells the body of organisms formed.
2. Composition of cell wall: Secondly we have to see the cell wall composition.
3. Prokaryotic or eukaryotic cell: We have to see the nucleus of organisms, if it has nucleus we can say that it is a eukaryotic cell.
4. Mode of nutrition: Mode of nutrition means is the organisms is autotroph or heterotroph.
If they have similarities, so it is placed in one group. If not so it is placed in different group or kingdom.
Explanation:
Water molecules from the less conentrated right side, will flow into the left side til they equilibrate- at equilibrium both sides will have the same concentration of solute.
In diffusion small water molecules can move across the phospholipid bilayer acts as a semi-permeable membrane into the extracellular fluid or the cytoplasm which are both hydrophilic and contain large concentrations of polar water molecules or other water-soluble compounds. Similarly, during osmosis the water passes through the membrane due to the difference in osmotic pressure on either side of the phospholipid bilayer, this means that the water moves from regions of high osmotic pressure/concentration to regions of low osmotic pressure /concentration.

Monosaccharides and disaccharides also
called sugars. Have sweet taste, water-soluble. Disaccharide output of two
monosaccharides are the same or different when hydrolyzed. Monosaccharide a carbohydrate that can’t be
hydrolyzed to simpler carbohydrate units.
Polysaccharides are extended polymers of monosaccharide units joined by
O-glycosidic linkages. Energy storage.
Answer:
The correct answer would be Atria push blood into the ventricles and Ventricles push blood out of the heart.
In humans, four chambered heart is present with two atria and two ventricles.
Deoxygenated blood from all over the body is passed into the right atrium through vena cava (superior and inferior).
Simultaneously, oxygenated blood from the lungs is passed into the left atrium of the heart with the help of pulmonary vein.
Both the atria contract at the same time to drain their blood into respective ventricles.
The ventricles undergo relaxation while receiving blood.
The valves present between the atria and ventricles (tricuspid and bicuspid valve) ensures that the blood flows in one way direction only. They shut down as the ventricles contract and produce the sound "lub".
The ventricles contract simultaneously to pump blood out of the heart. The right ventricle pumps deoxygenated blood into pulmonary artery which takes the blood to the lungs for oxygenation.
The left ventricle passes the oxygenated blood through aorta to all the parts of the body.
The pulmonary and aortic valves prevent the back flow of blood and shut at the same time which creates second sound called as "dub".
Answer: germ theory
Explanation: Germ theory of disease is a theory in biology. It says that small organisms (called germs), also known as microbes, cause diseases. Most, but not all diseases are infectious diseases. The germ theory states that small organisms cause a reaction in the body of those who are infected. The body's reaction to infection is called a disease.
