List three characteristics of living organisms
Answer: A gene is a sequence of nucleotides in DNA or RNA that encodes the synthesis of a gene product, either RNA or protein. A chromosome is a long DNA molecule with part or all of the genetic material of an organism. A allele is one of two or more alternative forms of a gene that arise by mutation and are found at the same place on a chromosome.

Answer:
The answer is sedimentary rock.
Explanation:
At the same time the particles of sediment begin to stick to each other - they are cemented together by clay, or by minerals like silica or calcite. After compaction and cementation, the sedimentary sequence has changed into a sedimentary rock.

Answer:
If a protein or molecule is taken up by the cell and must be digested it will make use of <u>lysosomes</u>.
Explanation:
Lysosomes are membrane-bound organelles that have a wide range of functions but their main 'job' is to break down large molecules into smaller molecules or to digest molecules that are present in excessive or unnecessary amounts. This is why <u>they contain important digestive enzymes known as hydrolitic enzymes.</u>
Lysosomes can break down, for example, large proteins into amino acids to provide the cell with the necessary nutrients.
Once you have obtained your salmon sample from a local store, you need to isolate the DNA from it and make many copies of the COI gene using the polymerase chain reaction (PCR).
