Answer: Option C  

Explanation:  

The walls of the left ventricle is thick as compared to the right ventricle this is because the arterial pressure in the left ventricle is more as compared to the right one.

The resistance in the (left) systemic circuit is 10 times greater than the pulmonary circuit.

The right ventricle needs to send blood to the lungs only but the left ventricle needs to send blood to the whole body and hence it needs to be more thicker as compared to the right one.

The childhood and early career of Charles Robert Darwin is discussed below.

<h3><u>Explanation</u>:</h3>

Charles Robert Darwin was born on 12 February 1809 in Shrewsbury, Shropshire. He was the fifth of six children of wealthy society doctor and financier Robert Darwin and Susannah Darwin. His grandfathers Erasmus Darwin and Josiah Wedgwood were both prominent abolitionists of the recent times.

Darwin started his career as an apprentice doctor, helping his father treat the poor of Shropshire, before he started to go to the University of Edinburgh Medical School. He found the lectures dull there and in his second year at the university he joined the Plinian Society, a student natural-history group. His father then sent him for a Bachelors of Arts degree which also he couldn't peruse.

After a long fight, he went on his famous voyage on HMS Beagle around the world where he collected his data and then gave his hypothesis in his book named '' On the Origin of Species by means of Natural Selection and Preservation of the Favoured Race in the Struggle for Life''
