Why nerve impulse is unidirectional? |
| Answer» An action potential can only depolarize the membrane “in front” as the membrane “behind” is in its refractory period and cannot be depolarizes, so the impulse travels in one direction only. The synapse acts as a valve and only allows one way flow due to the neurotransmitter being formed on one side of the synapse and the receptors only being on the other side. So, nerve impulsion is unidirectional. | |

How exchange of gases take palce in plants |
|
Answer» The exchange of gases in plants takes place through tiny pores called stomata which are present on the surface of leaves. The opening and closing of the pore is a function of the guard cells. But the exchange of gases not occurs only through stomata but the exchange of gases also occurs across the surface of roots, stems and leaves. Complete body of plants are in directly contact with surrounding environment. So every part of plant body are able to perform respiration. Through guard cells stomata pores |

Fireflies glow at night |
| Answer» Fireflies contain an organic compound in their abdomens called luciferin. As air rushes into the abdomen, it reacts with the luciferin. A chemical reaction gives off the familiar glow of a firefly. This light is sometimes called “cold light” because it generates so little heat. The firefly can regulate the airflow into the abdomen to create a pulsating pattern. Therefore, fire flies glow at night. | |

Excretion in animals |
| Answer» \xa0Many unicellular organisms like Amoeba throw out their wastes by diffusion from their body surface. Protozoan’s have no organs for excretion. As they live in an aquatic habitat, their wastes are eliminated by diffusion through the plasma membrane.Simple multicellular organisms like Hydra throw out solid waste matter through their mouth. Higher multicellular organisms have well-defined specialized excretory organs. These organs could be simple tubular structures as in flatworms and leech.The excretory organs of insects (e.g., grasshopper, cockroach and housefly) are also tubular. They remove nitrogenous wastes from the body fluid and help in maintaining the water balance in the body.In vertebrates, the main organs of excretion and maintenance of water balance are the kidneys. | |
