Answer:
Option C
Explanation:
Option
A. 6440 mL/min
B. 4340 mL
C. 3500 mL/min
D. 2940 mL/min
Solution
It is required to find the minute ventilation which is equal to the product of rate of breathing and the total amount of gas being inhaled or exhaled per breathe. Let this minute ventilation be denoted by "
"
Thus,
where TD is the tidal volume and Br is the rate of breathing
Substituting the given values we get
We will now reduce the air held in the conducting zone of respiratory system
Air held per breathe 
Total Air held
Amount of fresh air one can breathe in and out every minute
Hence, Option C is correct
Answer:
Water molecules are polar, so they outline hydrogen bonds. This gives water great properties, such as a for the most part high bubbling or boiling point, tall specific warm, cohesion, grasp, and thickness. Hydrogen has an electronegativity of 2.0, though oxygen has an electronegativity of 3.5. The refinement in electronegativities is 1.5, which infers that water can be a polar covalent molecule. In water, an electron from each of the hydrogen particles is drawn towards the oxygen particle. Protons, as unequivocally charged hydrogen particles, move outstandingly rapidly in water from one water molecule to the taking after, which is why the conductivity of water is modestly tall.
Answer:
Stabilizing selection
Explanation:
The process of natural selection selects a species in one of the three ways: stabilizing selection, directional selection and disruptive selection.
During the process of stabilizing selection, nature does not favour the extreme phenotypes of the population but the intermediate phenotype with the maximum number of population.
In the given question, the Robin laid four eggs, neither more than four nor less than four which could have more disadvantages than the advantages. Since the intermediate number of eggs is favoured by nature therefore the stabilizing pattern is observed.
Thus, Stabilizing selection is correct.
