The correct answer is epithelial
Epithelial lines the cavities and organs, as well as the skin. The other remaining ones are muscle, which builds muscles, nervous, which builds the nervous system, and connective, that connects joints or similar things.
Answer:
Oxygen
Explanation:
The formula for cellular respiration is oxygen + glucose -> water, carbon dioxide, energy. You can already cross out A and D because they aren't in the formula, so you have two left, water and oxygen. The reason why it is oxygen and not water is because without oxygen you can't even have water. also, I just got this right on my test :-)
Answer:
- B. substitution
- C. point mutation
- F. translocation
- A. mutation
- H. duplication
- G. inversion
- D. frameshift mutation
- E. insertion
Explanation:
Mutation:
A mutation is a change or alteration of the sequence of nucleotides in the DNA.
Mutations are of various types. Two of the major types are:
- Point mutations
- Chromosomal aberrations.
- Point mutations are changes in one or two or a few nucleotides of DNA. Point mutations are further of various types:
- Substitutions are exchanges of one nucleotide with another. Substitutions are also of three types: nonsense (codon changes to stop codon), missense (codon codes for a different amino acid) and silent mutations (codon codes for the same amino acid).
- Insertions/deletions are the addition or removal of one or a few nucleotides. Frameshift mutations alter the DNA reading frame, changing all the consequent amino acids.
- Chromosomal aberrations constitute translocations (part of one chromosome attaches to another), inversions (the orientation of the chromosome is altered), insertions (duplication or insertion of multiple copies of a chromosomal segment) and deletions (deletion of a chromosomal segment).
