Answer:
The requirement of different nutrients, divide them into 2 categories.
Explanation:
On the basis of requirement of nutrients in our food, the chemicals are divided into 2 types - macronutrients, and macronutrients.
Nutrients are the molecules present in the food nourishes the living organisms. The macronutrients are needed in large quantities and they provide energy to the organism.
There are 3 major macronutrients present in every kind of food - proteins, fats, and carbohydrates.
On the other hand, micronutrients are required very less amount to the animals. But they are important for nourishment of the body, but their quantity is very less. Example of micronutrients are vitamins, minerals, manganese, iron, potassium, etc.
Therefore, it is told one should take balance diet to get all the nutrients.
Answer:
The correct answer is: a. directs somatic motor axons to four of the six extrinsic eye muscles and also transmits parasympathetic visceromotor impulses to pupillary constrictor muscle of the eye.
Explanation:
<u>The </u><u>oculomotor nerve </u><u>(III) is the third cranial nerve.</u> It provides motor innervation to four of the six extrinsic muscles of the eye and has also a parasympathetic component in charge of contracting the pupil when the environment is rich in light.
The cranial nerve that innervates the lateral rectus muscles of the eye is the abducens nerve (VI).
The cranial nerve that provides motor innervation to the superior oblique muscle of the eye is the trochlear nerve (IV).

when it reaches either one of the "equinox" points in the sky.
<h2>Answer:</h2>
The boiling of water in the iron pan is the activity in which both conduction and convention are used.
<h3>Explanation:</h3>
Energy is transferred from one part of the matter to other part in three ways:
- Conduction
- Convection.
- Radiation.
Conduction is the movement of heat from the collision of the microscopic particles in the matter.
While convection is the transfer from the movement of fluids from one place to another.
In the water boiling activity, the pan is heated by the flame from taking the energy in the collision of atoms in the pan and the energy is transferred into the whole pan and eater molecules. This is conduction while in pan water movement from the bottom to top of pan is by convection.
