Jonas Salk developed the first successful polio vaccine in the 1950s, which significantly reduced the incidence of the disease.

Steve Jobs was the CEO of Apple and is famously associated with the introduction and development of the iPhone.

Joseph Pilates is the founder of the exercise method that bears his name.

Theodore Harold maiman was the first to produce laser in $1960$.

Homeostasis is the process of maintaining a constant and stable internal environment by an organism. This term was first described in 1865 by Claude Bernard and coined by Walter Bradford Cannon in 1930. The word is derived from Greek where 'home' means 'similar' and 'stasis' means 'stable'. So, the correct answer is "Walter Cannon'.

Process of warming of planet's surface and its lower atmosphere by the absorption of infrared radiations of long wavelength given out from the surface of a planet is known as green house effect.  In 1824, Joseph Fourier discovered the green house effect.

In the movie Lilo and Stitch, the alien creature is identified as Experiment 626, created by Dr. Jumba Jookiba, before Lilo names him Stitch.

Thomas Jefferson was the primary author of the Declaration of Independence.

In 1898, Tesla demonstrated a radio-controlled boat at Madison Square Garden. The audience was amazed, as they believed he was controlling the boat with his mind rather than radio waves.

Karl Correns discovered incomplete dominance in which none of the factors of a gene is dominant, the phenotype of the heterozygous dominant individual is the blend of dominant and recessive traits. He studied flower colour in Mirabilis jalapa and showed that a monohybrid cross between two pure varieties one with red flower petals another with white flower petals gives pink-flowered F$ _1$ plants. If these pink-flowered F$ _1$ plants are crossed, the F$ _2$ plants appear in a ratio of 1 : 2 : 1, having red, pink, or white flower petals, respectively. Pink-flowered plants are heterozygotes with a petal colour intermediate between the red and white colours of the homozygotes. Here, dominant allele (R) specifies red pigment colour, and recessive allele specifies no colour (r) and the flower petals have a white background colour. The pink heterozygotes (Rr) have about half the red pigment of the flowers in red homozygotes (RR) because the heterozygotes carry only one copy of “R” allele that produces colour, while the homozygotes have two copies.

Milton Berle, American comedian and actor, said this humorous variation on 'when opportunity doesn't knock, build a door.' It's about creating your own opportunities instead of waiting for them.
