Answer:
Common examples include carbon, sulfur, oxygen, iron, copper, aluminium. Elements are represented by symbols. Compounds are substances made from atoms of different elements joined by chemical bonds. They can only be separated by a chemical reaction.
Explanation:
Substances can be categorised as either elements or compounds. Both of these are made up of atoms, the only difference is an element is made of one type of atom whereas compounds are made of two or more different types of atoms.
Answer:
The correct answer will be options A, B and E.
Explanation:
Red blood cells or RBC or erythrocytes are the cells present in the connective tissue which forms the blood. RBC perform various functions in the body but the primary function is the transport of the gases in the body.
The RBC are continuously formed in the bone marrow region of the bone form the hemopoietic stem cell found in the bone marrow. These cells produce a large amount of RBC that is about 2 million cells per second in a healthy adult.
When RBC are formed posses nucleus but when mature, they lack nucleus that is genetic material and organelles like mitochondria so, they are not able to divide.
These RBC contain haemoglobin in their cytoplasm which shows high affinity to bind oxygen and low affinity to bind carbon dioxide to the iron group of haemoglobin.
Thus, options A, B and E are the correct answer.
Answer:
breaking down glucose into two molecules of pyruvate, producing ATP.

Answer:
Sensory transduction
Explanation:
Sensory transduction is a process by which the sensory neuron transforms the obtained sensory information into an electric signal. Sensory neurons are the afferent neurons and are activated when they receive stimulus from a sensory receptor. This is followed by the firing of action potential to convey the sensory information into the CNS through the cranial or spinal nerve.
Change in temperature serves as a stimulus for thermosensory neurons present in the skin. The activated thermosensory neuron then produces an electric signal by the process of sensory transduction during which a nerve impulse is generated and action potential to convey the information.
