Darwin called the ability of an organism to survive and reproduce in its environment fitness.
Some organisms were fit to do all of these things, whereas others were not.
Which of the following bio molecules typically contains both nitrogen and phosphate?
The answer to this question would be nucleic acids. That is because they contain a phosphate base and a nitrogen group.
Answer:
Linear DNA is unstable in bacterial cells and unless the lac+ gene is recombined into the bacterial chromosome, it will be destroyed.
Explanation:
Bacterial recombination is a kind of hereditary recombination in microorganisms described by DNA move starting with one life form called giver then onto the next creature as beneficiary. This cycle happens in three principle ways:
1. Change, the take-up of exogenous DNA from the general condition.
2. Transduction, the infection interceded move of DNA between microscopic organisms.
3. Formation, the exchange of DNA starting with one bacterium then onto the next by means of cell-to-cell contact.
Recombination into the bacterial chromosome necessary because linear DNA is unstable in bacterial cells and unless the lac+ gene is recombined into the bacterial chromosome, it will be destroyed.
The correct answer is b: cattle on rangeland. A point source of pollution occurs from a single identifiable and usually spatially narrow source. These sources of pollution are usually relatively easily to quantify and manage. In contrast, a non-point source of pollution, such as cattle on rangeland or irrigated agriculture, is variable on both spatial and temporal scales. These sources of pollution are difficult to quantify and manage.
