Answer:
All of them are mostly true but I would say option 2 :)
Exercise or any other physical activity, increases the oxygen demand in the lungs and affects the flow of air into the lungs.
Tidal Volume: The amount of air inspired (air that leaves or enters the lungs) during breathing is called tidal volume. With the increase in physical activity such as exercise, the tidal volume increases to allow more gaseous exchange. During exercise, the amount of air to be inhaled increases, thus the tidal volume also increases.
Alveolar Ventilation: It is also known as alveolar volume. It is the amount of air that enters the alveoli in one minute. Alveolar ventilation also increases with the increase in the vital volume due to exercise. This is because oxygen demand increases during exercise.
Anatomical Dead Space: It refers to the air that is directed towards the alveoli but does not participate in the gaseous exchange It decreases during exercise due to increase in ventilation.
A pollutant is a substance or energy introduced into the environment that has undesired effects, or adversely affects the usefulness of a resource.
The answer is The bone will become soft and Flexible
Inorganic component of bone would be consist of calcium and other deposition that makes the bone hard. The inorganic components are easily dissolved by acid which are used by osteoclast cell to remodel the bone. After the inorganic component removed, the bone will lose its hardness which make them more flexible.
Answer:
The correct answer is b. All round seeds
Explanation:
If an RR plant is crossed with an rr plant than all the phenotype will produce round seed and the frequency of the Round seed plant to wrinkled seed plant would be 4:0.
R R
r Rr Rr
r Rr Rr
So all the phenotypes will be heterozygous dominant for the round seed which means that all phenotypes will have a single dominant allele for round seed which is enough to express round seeds in the phenotypes.
