Answer:
A is the correct answer.
Explanation:
A vulture does eat dead animals but it itself is not classified as a decomposer due to the fact that the remains of most of the animal is still there.
The three most important Mendel law is the law of dominance, law of segregation, and law of independent assortment. The law of dominance is when a trait is more recived or more dominate than other trait. For example a flower, if a flower is red most of the flowers will be red, but one will be white. The white flower has a recessive trait. The law of segregation is when a offspring randomly receive one allele of every trait from each parent. The law of independent assortment states that just because you received one allele doesn't mean another dominate allele will be passed also.
All of these are necessary, but what you need the most I would say is
D. Movement
Without movement, your body can stiff up, causing muscle problems which can lead to many various things.
