Answer: It is A
Explanation: C and D are jokes/ complete lies. B is wrong because Darwin did observe that animals and plants adapted (evolved) to suit their environments.
Answer:
Period of the waves = 0.00013 s (Approx.)
Explanation:
Given:
Propagation speed = 150 m / s
Wavelength = 0.02 m
Find:
Period of the waves
Computation:
Period of the waves = Wavelength / Propagation speed
Period of the waves = 0.02 / 150
Period of the waves = 0.00013 s (Approx.)
The Iron in the molecule binds to the oxygen. Carbon Dioxide does not bind to a cell but rather, is carried in the blood as bicarbonate.
Answer:
An egg placed in salt water will float!
Explanation:
In normal tap water, an egg will sink because it's density is greater than the density of water. But, when salt is added to the water, it's density becomes greater than the egg's density. The term used to describe this is "buoyancy."
