C, because it's the structural component is the backbone of DNA and RNA
Answer:
Correct option A
Explanation:
Foreshadowing is giving a hint that something is going to happen. This is done by showing certain events, people or information that are an indication of something that will occur later on in the story. Foreshadowing can add tension or expectation to the narrative.
Example of Foreshadowing:
A pipe is going to burst, but before it does, the author writes a scene where the family notices a small dark spot on the ceiling, but ignores it.
Yolks are an important component of the eggs since they
nourish the young embryo as it develops into a young juvenile organism. The
yolk is important especially when the embryo is not attached to its parent (in
oviparous organisms) like in humans. Humans embryos are able to get their
nourishment directly from their mothers in the womb (through the placenta)
hence don’t require a yolk (viviparous organisms).
Answer: Biodiversity
Explanation: Biodiversity is in all ecosystems and it's everywhere. The reason they can compete and both succeed is because of biodiversity, they are not stuck to eating one animal there are thousands of different types of animals and because of this their is enough to go around. However if their wasn't biodiversity and their food choice was limited one would fail if competing in the same ecosystem.
<span>Spiral galaxies are generally classified as galaxies that are circular in nature, with a bright nucleus that is enclosed by a thin outer disc. Normal spiral galaxies and barred spiral galaxies differ in appearance because normal spirals have 'arms' that emanate from the nucleus (which looks like a sphere that has curved arms coming out of the nucleus center), while barred spirals have bars (bright line features) that go straight through the nucleus, with arms that unwind from the ends of the bar.
Elliptical galaxies look like very bright stars - they are shaped like elongated spheres, emanate a lot of light (but the brightness is concentrated in the center and dissipates the further out from the center you go), and vary in size.
Irregular galaxies are classified as such because they don't fit into either the spiral or elliptical galaxy groups. They have a wide variety of shapes and sizes, and have no inherent regular or symmetrical structure.</span>
