Answer:
Capillary action refers to the motion of the liquid along the solid surface resulting due to the attraction of the molecules of the liquid. Capillary action is used by the plants to bring water up to the roots and then from stems to the remaining parts of the plant. The liquid molecules are fascinated by the molecules present within the stem. This attraction is utilized to assist the water to move up from the ground and to get distributed to all the parts of the plant.
There are three intermolecular forces that play an essential role in the procedure of capillary action:
1. Adhesion refers to the procedure of combining one substance with another. In plants, adhesion permits the water to attach with the plant's organic tissues.
2. Cohesion maintains the molecules of a similar substance to remain in combination. In plants, cohesion makes the molecules of water to stay together.
3. Surface tension refers to the influence of the intermolecular attraction, which makes liquids to produce a top or outer layer that works like a kind of thin film. Surface tension is accountable for the water drops to attain its shape and for holding the compositions together as plants soak up the water.
Erythrocyte is an example of a specialized cell
Answer:A. Protists B. Bacteria C. Animals D. Plants E. Fungi F. Archaea
Explanation:viruses are small non-living particles that contains hereditary materials.viruses attack cells of other organisms such as plants , bacteria ,archaea etc.
Viruses are acellular and contains either DNA or RNA.they cannot synthesis protein as they lack ribosomes ,so they use the ribosomes of the cell they have invaded to synthesize they proteins they need.
A virus usually has a central core surrounded by an outer protein coat called capsid.
Viruses can reproduce only within the living host cells and they are specific to the type of cells they attack.they attack plants through insect vectors or through openings on the plants.
Viruses can affect bacteria by injecting their nucleic acids through the cell wall and into the bacteria cell.such viruses are called bacteriophages.
Answer:
C.
Explanation: Mitosis is a process where a single cell divides into two identical daughter cells (cell division). During mitosis one cell? divides once to form two identical cells. The major purpose of mitosis is for growth and to replace worn out cells.
