Which of the following is true of receptors for dynamic equilibrium?
gulaghasi [49]

Answer:

The correct answer is option D.

Explanation:

Dynamic equilibrium refers to the sense, which interprets angular acceleration in the three-axis of rotation that when combined provides a sense of equilibrium when movement takes place. The receptors for dynamic equilibrium are known as ampulla, maculae are the receptors of static equilibrium.  

The movement of the head does stimulate dynamic equilibrium receptors, as these receptors are situated in the inner ear that moves with the head. The receptors for dynamic equilibrium are situated in the semicircular canals. The receptors for dynamic equilibrium react to rotational forces, as the receptors are located on the three-axis, thus, they can detect rotation, that is, angular momentum.

Answer:Answer:

For 1: The correct answer is Model 1, 2, and 4.

For 2: The correct answer is Option 1.

Explanation:

For 1:

An element has 3 subatomic particles: electrons (E), neutrons (N) and protons (P).

Atomic number is defined as the number of protons or number of electrons.

Atoms having same number of protons are same. From the given models, Model 1, 2 and 4 have 2 protons with different neutrons. Hence, these models belong to same element.

For 2:

A compound is defined as a substance in which two or more types of elements combine in a fixed ratio. For Example:  is a compound made out of atoms of carbon and oxygen.

Hence, the correct answer is Option 2.
