Answer:
The correct answer would be
- Concave lens for nearsightedness
- Convex lens for farsightedness
Nearsightedness or myopia is a condition in which a person can see the nearby objects clearly but is unable to see the objects present at a farther distance clearly.
It is usually caused due to elongation of the eyeball or when the lens becomes too curved.
It can be corrected by using a concave or diverging lens of appropriate power.
Farsightedness or hyperopia is a condition in which a person can see the distant objects clearly but is unable to see the nearby objects distance clearly.
It is usually caused due to shortening of the eyeball or when the lens loses its curvature.
It can be corrected by using a convex or converging lens of appropriate power.
<h2>Regional specialization of Human Nervous System</h2>
Explanation:
The statements that illustrate the regional specialization of human nervous system are-
a. Sensory information may be processed in the occipital lobe or the temporal lobe.
c. Reading a printed word out loud and then thinking of a related word involves the visual cortex, Broca’s area, and the frontal and temporal lobes.
Humans have the most developed nervous system among all the living organisms. Various parts of the nervous system has been specialized for various function. The human brain has been divided into different parts like cerebellum, cerebrum , medulla oblongata etc which are further divided into specialized parts. Each part is specialized to carry out particular function. Moreover, the nervous system has different types of neurons like motor neuron, sensory neurons and interneurons. Each type of neuron has specialized function.
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.
The biome that has over 100 inches of rain each year is the Rainforest. Therefore, the Rainforest has abundant rainfall.
A Muscle Contraction Is Triggered When an Action Potential Travels Along the Nerves to the Muscles. Muscle contraction begins when the nervous system generates a signal. The signal, an impulse called an action potential, travels through a type of nerve cell called a motor neuron.
