Fossils are preserved remains/traces/marks of an animal that lived millions of years ago. Some stuff that are found as fossils include shells and bones (since they are hard materials). Fossils can also be found trapped in sap/amber.

Why can't you use fresh pineapple in jello
Nataly [62]
Pineapples, unlike most other fruit, contain an enzyme called bromelain, that breaks up the gelatin into it's amino acid building blocks. [Enzymes are biomolecules that catalyze chemical reactions; most of them are proteins themselves.] Due to the bromelain, your jello doesn't become (or stay) solid.

How can point and frameshift mutations contribute to biodiversity of Earth? Explain your<br> answer.
Blizzard [7]

Answer:

<u><em>These mutations form new alleles that increase genetic variation in a population. This variation may lead to new species which increases biodiversity.</em></u>

Explanation:

Mutations are randomly occurring modifications that exist within the genetic code, leading to replication errors in DNA. DNA molecules are long-chain, helical macromolecules that store genetic material. They consist of different monomer sequences called nucleotides. In a reading frame, which contains instructions for protein production, they shape base pairs and codon sequences.

Single nucleotide polymorphisms are normal, as silent mutations, which sometimes result in no changes in amino acids. Some mistakes add a random nucleotide (SNP) in point mutations resulting in new alleles.

Frameshift mutations occur from nucleotide insertions or deletions that are not divisible by 3. This results in the codon requiring more or fewer nucleotides which disrupt the reading frame, resulting in a separate protein translation.

What is the difference between gradualism and punctuated equilibrium?.
SpyIntel [72]

Answer:

The gradualism model depicts evolution as a slow steady process in which organisms change and develop slowly over time. In contrast, the punctuated equilibrium model depicts evolution as long periods of no evolutionary change followed by rapid periods of change.
