Answer:
What type of chemical reaction takes place when lood is digeste
Decomposition reaction takes place during digestion of food since it involves breaking down the large nutrient molecules in food into smaller molecules.
Which gas is liberated when a metal reacts with an acid?
hydrogen
As a general rule, acids react with most metals producing salt and hydrogen, unlike acid-base reactions in which case we get water. Hence, the gas produced is hydrogen.
Define water crystallization
Crystallization or crystallisation is the process by which a solid forms, where the atoms or molecules are highly organized into a structure known as a crystal. Some of the ways by which crystals form are precipitating from a solution, freezing, or more rarely deposition directly from a gas.
Name the pigment which is necessary for plants to be autotroph
chlorophyll pigment
Answer. Carbon dioxide, water, chlorophyll pigment, and sunlight are the necessary conditions required for autotrophic nutrition.
Which chamber of human heart pumps oxygenated blood to the body?
The right ventricle pumps the oxygen-poor blood to the lungs through the pulmonary valve. The left atrium receives oxygen-rich blood from the lungs and pumps it to the left ventricle through the mitral valve. The left ventricle pumps the oxygen-rich blood through the aortic valve out to the rest of the body.
Name respiratory organ of fish.
Oxygen and carbon dioxide dissolve in water, and most fishes exchange dissolved oxygen and carbon dioxide in water by means of the gills.
What is the function of receptors in human body?
Receptors are present over all parts of the body, for example, in skin, eye, nose, tongue etc. They detect the signals and then send them to the brain in the form of electrical signals. If receptors are damaged, they will not detect the input, leading to harm for our body in a dangerous situation.
Which part of CNS is connected to reflex arc?
spinal cord
The reflex arc is the path through which the reflex action takes place and hence the only part of the Central Nervous System which takes part in it is the spinal cord.
