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
The answer is genetic factors, chromosomes, meiosis.
W.S. Sutton proposed that the <u>genetic factors</u> are located on <u>chromosomes </u>and these factors segregate during <u>meiosis </u>and the production of gametes.
Genetic factors are now known as genes, which are sequences on chromosomes. They code for proteins. Meiosis is a cell division resulting in the reduction of number of chromosomes in gametes.
Nucleic acids, which include DNA (deoxyribonucleic acid) and RNA<span> (ribonucleic acid), are made from monomers known as nucleotides. Each nucleotide has three components: a 5-carbon sugar, a </span>phosphate<span> group, and a nitrogenous base. If the sugar is deoxyribose, the polymer is DNA.

Answer:
The breating rate is the dependent variable because it can be affected by varying weights.
Explanation:
In an experiment, the dependent variable is the variable that is not manipulated but is influenced by the changes that are done to the independent variable. In other words, it depends on the independent variable.
So in this case, the breathing rate is the dependent variable and the weight differences is the independent variable because the change in weight is what is changed to see if it will affect the breathing rate, which is the dependent variable.
