Capillaries are tiny blood vessels connecting arteries to veins. These blood vessels carry oxygen and nutrients to individual cells.
The capillaries are very thin and highly branched. THis helps in diffusion of gases with all parts of the body as well as helps the supply of blood to every small part of the body.

Oxides of metals which have both acidic as well as basic behaviour are known as amphoteric oxides. Such metallic oxides react with acids as well as base to produce salt and water. Examples of Amphoteric oxides are aluminium oxide and zinc oxide.

Carbon-dioxide combines with haemoglobin to form carbaminohaemoglobin. This is one of the form in which carbon-dioxide exists in blood. About 10% of carbon-dioxide is carried in blood in this way.

Ohm’s law states that the current passing through the conductor will be directly proportional to the potential difference, if the temperature remains constant throughput the circuit.
Mathematically, Ohm's law is given by :
v∝ r
v =IR
R is resistance off the circuit. It is measured in Ohms.
The attached figure shows the circuit diagram to verify ohm’s law. The second figure is the V-I graph for ohm’s law verification.

- The arteries divide in to extremely small thin branches on reaching the tissues. These small branches are called as capillaries.
- Capillaries have walls and are one-cell thick through which the exchange of materials between the blood and surrounding cells take place across his thin wall.

Biological magnification refers to the process of increase in the concentration of a toxic chemical with increasing trophic level in a food chain. Harmful or poisonous substance such as DDT sprinkled to kill pests on plants enter the food chain. The plants absorb these harmful chemicals from soil along with water and minerals. They enter the food chain at producer level and then transfers to the next trophic level. The tertiary consumers get more higher levels of these chemicals.

Generally the reaction of a metal with an acid is written as
Metal + acid ------> Metal salt + hydrogen gas
Now this reaction is not true for all the metals. Only those metals which are more reactive than hydrogen will liberate hydrogen from the acid and form the corresponding metal salt. These metals are placed above hydrogen in the reactivity series. As copper is less reactive than hydrogen, therefore it will not liberate hydrogen gas from the acids like HCl, HNO3, H2SO4 etc.
But sulphuric acid is a strong oxidising agent, therefore it will oxidise copper metal to Cu2+ ion. However, no hydrogen gas will be formed, only copper metal will be oxidised here. On the other hand, HCl is not that strong oxidising agent, in fact its use as an oxidising agent is not too well known. Hence it does not react with copper metal at all.

Plant hormones are simple organic substances transported through xylem, phloem or by diffusion. They are produced in one part of the plant and transported to the other. No specific organs are involved in the synthesis of the plant hormones.
Examples: Auxins, cytokinins, ethylene, gibberellins.

Amoeba takes in food using temporary finger-like extensions of the cell surface which fuse over the food particle forming a food-vacuole. Inside the food vacuole, complex substances are broken down into simpler ones which then diffuse into the cytoplasm. The remaining undigested material is moved to the surface of the cell and thrown out. The complete phagocytosis process includes intake, digestion , absorption, assimilation, and egestion process.

Heterocrine glands are those glands that possess both exocrine ( which release chemical substances through ducts) as well as endocrine parts ( which release chemical substances directly into bloodstream or body parts).
Two examples of heterocrine glands are-
1) Pancreas ( as they perform both exocrine and endocrine function)
They release insulin and glucagon into bloodstream ( endocrine function) and release digestive enzymes through ducts in the digestive tract ( exocrine function).
2) Ovary : It releases steroid hormones ( estrogen and progesteron) into bloodstream and also performs exocrine function by producing ova into duct.
