Explanation:
Can you same the same thing about organisms and aquatic animals, not every single living thing has an heart to survive.
The right answer to this question is option C. the traits acted upon natural selection were genes.
At the time Charles Darwin developed the evolution theory, there wasn't a single study about genes in all science scenery, that could be explained by the lack of technology to study them and even to know they existed in the first place.
So, his theory was basically talking about adaptation, if an organism can't survive a specific environment, he'll probably die until another generation comes in and this one can survive in this environment, passing their genes to the next ones. The lack of information was the knowledge about the genes we have today, that's why most scientists take only the new Darwin theory, that includes the study of genes.
Answer:
In the electromagnetic spectrum, the visible spectrum is the part, which is perceptible to the human eye. The electromagnetic spectrum in this array of wavelengths is known as simply light or the visible light. A general human eye will react towards the wavelengths in the range between 380 to 740 nm. A human eye sees the sky as blue that comes in the wavelength 490 nm because of the scattering of the visible light by the particles in the atmosphere. This concludes that 490 nm is the sole wavelength, which is reaching the eye.
Answer:
The conception about greenhouse gases that all gases are harmful is wrong. The greenhouse effect is beneficial in that storing certain carbon keeps our planet's temperatures mild and ideal for living things. Absence of greenhouse gases in atmosphere affect the the Earth's average surface temperature and it will be zero degrees Fahrenheit.
People has misconception about the greenhouse effect, as if it were a negative thing. This is not negative in all aspects, but people are worried because the atmosphere on Earth is very rapidly warming up. It is happening as we are introducing more greenhouse gases to our environment at the moment, creating a stronger greenhouse effect. The increased greenhouse effect is causing changes that can impact our lives on our planet.
