Answer: An atom is the smallest particle of an element which still retains the properties of the element.

Explanation: An atom is made up of three components: electrons, protons and neutrons. Electrons are negatively charged and are located in the shells where they revolve round the nucleus. Protons and neutrons are found in the nucleus. Protons are positively charged while neutrons have no charge. The negative charges on the electrons balance the positive charges on the protons thereby making an atom neutral.

The lungs remain inflated because ___________.a. intrapleural pressure is exactly equal to atmospheric pressure b. intrapleural
kkurt [141]

Answer:

Option C,  Intrapleural pressure is less than intrapulmonary pressure

Explanation:

During inspiration, the air enters the lungs due to lower pressure in the intrapulmonary or intra-alveolar  than the atmospheric pressure. During quite respiration, the intrapulmonary pressure reduces to a pressure that is 3 mm Hg lower than that of atmospheric pressure. During quiet expiration, the intrapulmonary pressure rises up to a pressure that is 3 mm Hg higher than that of atmospheric pressure. This leads to lack of air in the intrapleural space thereby producing intrapleural pressure which is lesser than that of intrapulmonary pressure.  

This difference in pressure (i.e higher pressure with in the lungs than the atmosphere)  causes lungs to remain attached to the chest wall and hence looks inflated.  

Hence, option C is correct

On-center cells: A. are excited by light that falls in the periphery of their receptive field. B. are excited by light that fall
Elena L [17]

Answer: B) are excited by light that falls in the center of their receptive field.

Explanation:

There are two types of bipolar cells present in the retina which are differentiated on the way the centres of their receptive fields respond to light. The names of bipolar cells are ON-centre and OFF-centre.

If a light fall at the centre of the receptive field of a bipolar cell, it will experience an exciting effect on that cell, resulting in it being depolarized, it is an ON-center cell.

Hence, the correct option is B.
