Explanation:
Lucille's cells need oxygen. In order for cells to properly function, they need to be oxidized. If Lucille's respiratory system is not working then her body cannot receive the oxygen that it needs in order to send to her blood cells. The circulatory system pumps Lucilles's blood around her body but if there is no oxygen, Lucille's cells/heart cannot properly function, this making it difficult for her to play soccer.
Fossils can give information about past environmental conditions by showing the type of animal they belonged to. If a scientist found a whale fossil in a desert, he/she could assume that the desert was once an ocean as whales only live in oceans. If someone found a fossil of a lizard that inhabited trees, in the middle of the ocean, then he/she could assume that the ocean didn't exist at one point and instead, there might have been a forest in it's place.
Hope this helps!

The answer is true for this question
Answer:
A frameshift mutation can be described as a genetic mutation in which a single nucleotide or more than one nucleotide is inserted or deleted from the sequence of the DNA. As the gene expresses itself in the form of triplets of a genetic code, insertion or deletion can cause devastating changes in the genetic code due to which wrong proteins will be synthesized.
Frameshift mutations can be more noticeable than the substitution mutation. In a substitution mutation, only one of the nucleotides is shifted with another. The entire genetic code is not affected by it.
