Answer:
other evidence must be taken into consideration in addition to DNA evidence found at a crime scene are finger print, footprint, entomological research result i.e the type of organism(insects) found at the scene might give a pointer to the type of death
Explanation:
Along with DNA evidence, fingerprints, physical evidence (objects) and witnesses must be taken into consideration.
Answer:
UUAC
Explanation:
Transcription is the first process of gene expression in organisms. It involves synthesizing a complementary strand of mRNA from a DNA template. This process is carried out by an enzyme called RNA polymerase, which first unwinds the DNA molecule and then adds complementary nucleotide bases to the growing RNA molecule.
Adding of nucleotides by RNA polymerase follows the complementary base pairing rule, which is a phenomenon whereby Adenine (A) binds to Thymine (T) in an hydrogen bond and Cytosine (C) binds to Guanine (G), A-T, G-C. During transcription, Uracil (U) replaces Thymine.
RNA polymerase synthesizes a nucleotide base complementary to the one it reads on the DNA i.e if it reads Adenine on the DNA, it adds Uracil.
Hence, a DNA molecule with nucleotide AATG will be read by RNA polymerase and it becomes transcribed into a RNA molecule with nucleotide UUAC.
B. amylase
C. trypsin
D. lipase
Trypsin is the enzyme that is specific for proteins. Correct option is C.
The enzyme that is specific for proteins is trypsin. Trypsin is a digestive enzyme that breaks down proteins by cutting the peptide bonds between amino acids. It is produced in the pancreas and secreted into the small intestine, where it aids in the digestion of proteins.

B.Living things can recycle elements within an ecosystem as long as decomposers are present.
C.Matter flows in a one-way direction with a 10% loss at each move up in trophic level.
D.Elements continuously cycle between the physical environment and living organisms.
Correct answer choice is:
D) Elements continuously cycle between the physical environment and living organisms.
Explanation:
Any nonliving matter that living things want is termed a nutrient. Carbon and nitrogen are parts of nutrients. Unlike energy, the object is converted into ecosystems. Decomposers deliver nutrients when they cut down dead organisms. When one organism eats a different organism, it takes all of its nutrients. Nutrients can also cycle out of an ecosystem. Falling leaves may be moved out of an ecosystem by a water. Decomposers cut down dead organisms into nutrients and carbon dioxide, which they respire into the air.
