Answer:
D. Genetic recombination would not occur.
Explanation:
If this did not occur, all individuals would be identical to its parent unless a mutation occurred.
Answer:
B.) metamorphic
Explanation:
Metamorphic rocks come from other kinds of rocks, like igneous and sedimentary. They are created by intense heat and high pressure.
Answer:
Substitution
Explanation:
Mutations can simply be defined as change in the structure of a gene. Mutation can be of different types. These include, but not limited to:
- Insertion: This involves the insertion of extra base pairs into a DNA
- Deletion: Loss of DNA section
- Substitution: When a nucleotide base gets substituted with another base.
<em>Substitution of a base can lead to coding of different amino acid and hence, protein. It can also lead to coding of the same amino acid, otherwise known as silent mutation. Base substitution can also lead to the amino-acid-coding codon becoming a stop codon, leading to an incomplete protein.</em>
The correct answer is substitution.
Elevated carbon dioxide levels may mitigate losses of biodiversity from nitrogen pollution. ... Rising levels of carbon dioxide may overheat the planet and cause other environmental problems, but fears that rising carbon dioxide levels could directly reduce plant biodiversity can be allayed, according to a new study.
2 strands of DNA=hydrogen bonds
2water molecules=polar convalent bonds
NACL=ionic bond
H2=ionic
