Answer: Point mutation is easily reversible, thus non-lethal
Explanation:
Point mutation is caused by exchange of a single nucleotide for another. These change is called
1) Transition (when a purine base substitute another purine base, or pyrimidine bases substitute each other)
2) Transversion (when a purine base substitute a pyrimidine base).
However, note that a point mutation can be easily reversed by another point mutation; so, the claim that a nucleotide difference in the Hsr12 gene caused the human disease is inaccurate
The correct answer would be D.
After many generations, only those with genes suitable to live in harsh environments can live. These genes are passed onto their offspring and then we see a rise in antibiotic resistant strains of bacteria such as Methicillin Resistant Staphylococcus Aureus (MRSA).
The weigh of each tomato is the dependent variable
Answer:
get wheat that has the desired content (in this case high fiber content)
breed them
amongst the offsprings/ wheat produced, select the ones with highest fiber content
breed them
repeat this process for many generations
Explanation:
The external covering of diatoms are made up of, while slime molds have cell walls containing. diatoms are because they make food through photosynthesis, while slime molds are because they eat decaying plant matter
