Answer:
The Sun is completely blocked in a solar eclipse because the Moon passes between Earth and the Sun. Even though the Moon is much smaller than the Sun, because it is just the right distance away from Earth, the Moon can fully blocks the Sun’s light from Earth’s perspective.
Explanation:
Evolution is caused by genetic mutations that become favorable for survival.
For example if a bird has a mutation that gives it a longer beak and it lives in an environment in which a longer beak lets the bird catch more food- the longer beak becomes a favorable trait.
Now the bird is able to survive “better” thus it lives longer(due to its ability to catch more food). Because of this it reproduces more and passes the trait on to its offspring.
Overtime this mutation takes over the population of birds in the area.
According to modern systems of classification, birds are descendants of T<span>heropoda dinosaurs. These dinosaurs are called Paraves. From this clade, a node is made during the evolution. The new clade is called Aves. This is where birds are classified.</span>
Heterozygous straight (F) x heterozygous bent (f)
________
<u>|FF | Ff |</u>
<u>|Ff | ff |</u>
That means 1/4 will be 100% straight
2/4 will have straight with a recessive trait of bent
1/4 will be recessive recessive which means bent
So out of 4 chimpanzees, 1 of them will have bent.
Hope this is what you wanted help with. :)
Answer:
Mutation is a change that occurs in our DNA sequence, either because of errors when DNA is copied or because of environmental factors such as UV light and cigarette smoke. This results in protein changes that have been made. It could be a bad thing or a good thing.
