Answer: A. sorE encodes a gene that increases I. hockious virulence
Explanation:
Notice that at the start of the study, there were 10 times mutant gene lacking sorE compared to the wild type. After 24 hours, it reduced to 5 times compared to the wild type, this is an indication that sorE is a virulence gene and it's absence reduces the virulence of the bacteria.
Answer:
1.) 80 chromosomes in each of the daughter cells. 2.) Two daughter cells are produced. 3.) The daughter cells are identical.
Explanation:
1.) In mitosis, a parent cell divides to form two daughter cells through the mitosis phases creating the same amount of chromosomes for each daughter cell as the parent cell.
2.) The parent cell divides to form the two daughter cells in cytokinesis.
3.) The daughter cells are direct replicas of the chromosomes in the parent cell unless there is a mutation in the DNA when it is being copying.
Answer: Every species has a carrying capacity, even humans. However, it is very difficult for ecologists to calculate human carrying capacity. Humans are a complex species. We do not reproduce, consume resources, and interact with our living environment uniformly.

<span>This is because benthic zone are too
dark to support photosynthesis. Due to their depths, sunlight is unable to penetrate
the above lying waters and reach the region. This way plants cannot carry out
photosynthesis hence cannot grow. This is why only </span>decomposers,
detritus feeders can be found in the benthic zone.
