you didn't list choice but i'm guessing chloroplasts
Survival of the strongest... an organisms strength does not affect the natural selection process. Natural selection is adapting the species to be able to better survive in its environment. In order to better survive, an organism does not to be strong. e.g. a plant is probably not a “strong” organism and natural selection doesn’t change that in most cases
Answer:
It would most likely render the protein nonfunctional or mis-functional.
The mutation could result in three outcomes:
- Silent mutation, which changes the codon to the same amino acid. (AAA->AAG, both are lysine). But since the problem specified that it has a "slightly different amino acid sequence," we can assume this doesn't happen.
- Nonsense mutation, which changes a codon to a stop codon. This would end the chain of amino acids, making the protein potentially nonfunctional.
- Missense mutation, which changes a codon to another completely different codon. This can be harmful, as in sickle-cell disease, where just one amino acid, glutamic acid, is changed to valine.
irrigation systems, water moves across the surface of an agricultural lands,
Two different methods of irrigation are- modern methods that include sprinkler irrigation and drip irrigation; traditional irrigation that includes manual irrigation where water is pulled out by the farmers themselves from the wells and canals to irrigate the land.
the answer is a because if the model is based on experimental data it wont be good unless it has been tested.
