Answer: D. Quantitative Observation.
Quantitative observation is the usage of your senses (smell, sight, touch, etc) or measurements to observe the results.
Answer: Its possible genotypes are PPSS, PPSs, PpSS, and PpSs.
Explanation: If P represents the allele for purple kernel and S represents the allele for smooth seed shape; if P and S are dominant alleles, PP and Pp will manifest outwardly as purple kernel because P is dominant and will be able to express itself whether in a homozygous or heterozygous state. Similarly, SS and Ss will manifest outwardly as smooth seed shape because S is dominant and will be able to express itself whether in a homozygous or heterozygous state.
Therefore, PPSS, PPSs, PpSS, and PpSs will appear outwardly as purple kernel and smooth seed shaped corn plant.

Answer: To meet the demand of more oxygen by the body.
Explanation: During the time of exercise the need for oxygen by the body increases. The minute ventilation of an individual will increase due to increase in the tidal volume and frequency of breathing.
The extra space is provided by the inspiratory reserve volume which acts as a reservoir of extra lung volume that can become inflated with air and as we need it.
So, Inspiratory reserve volume and expiratory reserve volume decreases during heavy exercise as there is a need of more inhalation of oxygen and more exhalation of carbon dioxide as tidal volume increases and cover the space.
The basic structure of bones is bone matrix, which makes up the underlying rigid framework of bones, composed of both compact bone and spongy bone. The bone matrix consists of tough protein fibers, mainly collagen, that become hard and rigid due to mineralization with calcium crystals.
