Mountain slopes have faster erosion because it is easier for fast moving bodies of water to carry down eroded material downhill, rather than across flat land.
Answer:
B
Explanation:
Competition is defined as an activity done by two opposing sides, both of which are trying to do better than the other.
Answer:
When a sodium atom that has lost an electron comes near a chlorine atom that has gained an electron, an ionic bond is formed.
Explanation:
The bonds which are produced between a metal ion and a non-metal ion are termed as ionic bonds. Sodium is metal while chlorine is a non-metallic element, ionic bonds are formed in between them.
Sodium has one electron in its outer most shell whereas a chlorine atom has seven electrons in its outermost shell. To become stable, sodium donates its electron to the chlorine atom and hence ionic bond is formed between them.
<span>Vestigial structures give
us evidence of organs or body parts that existed at one time and
eventually were not needed by the species to survive. For example, you
have an appendix but it's not an organ that is used very often, if at
all, by the body. However, in rabbits the appendix is a vital part of
their digestive system. Scientists think that the appendix helps to
digest large amounts of wild grasses and grains, which would have been a
useful organ to early humans while they were relying heavily on those
fibrous foods to sustain themselves. So vestigial structures basically give us an idea of something that a
species needed at one time in their past to survive but due to change
and evolution, they don't need it for survival anymore so it gradually
has started to disappear.
hope it helps
