Answer: Receives food that the duodenum have been digesting;
And then begins the absorption of major nutrients as well as Vitamin B12 and bile salts.
Explanation: The duodenum which is the first section of the small intestine is where most of the chemical digestion takes place as well as absorption of iron, enzymes are been secreted from the gall bladder, pancreas, liver et cetera into the duodenum to help breakdown the fat and protein as well as further break down the carbohydrates.
The food then goes through the jejunum and lleum where absorption of major nutrients as well as Vitamin B12 and bile salts into the blood stream begins.
A) photoreceptors
b) myopia
We usually view objects when they are illuminated by white light, usually sunlight or ordinary room light. White light is a mixture of all colors, in roughly equal proportions. White objects look white because they reflect back all the visible wavelengths of light that shine on them - so the light still looks white to us. Colored objects, on the other hand, reflect back only some of the wavelengths; the rest they absorb. For example, if white light shines on a red ball, the ball reflects back mostly red light, and so we see red. Most of the greens and blues that are part of white light are absorbed by the ball so we cannot see them. Likewise, a blue book is reflecting the blue part of the white light spectrum. The red and green parts are absorbed by the book.
What happens when red light shines on a red ball? It continues to reflect the red light, and so it is still red -- but a white ball would also look red in red light, because it reflects all colors. If instead we shine blue light on a red ball, it will look dark, because it does not reflect blue light. It cannot look red unless there is red light coming to it from the light source. And it cannot look blue because the red ball absorbs blue light. So when we ask what color an object is, the answer is not simple - it depends on what color light we are using to see the object.
One consequence of the fact that different colored objects absorb different wavelengths of light is that darker objects heat up faster in the sun than white ones do - because they absorb many of the different wavelengths of light energy, while white objects reflect most of the wavelengths.
False the earth doesn't travel through space as a spaceship would the earth orbits around the sun. While a spaceship could just orbit the sun it usually has a destination in where the earth does not.
