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.
Most protists move with the help of flagella, pseudopods, or cilia. Some protists, like the one-celled amoeba and paramecium, feed on other organisms. Others, such as the one-celled euglena or the many-celled algae, make their food by photosynthesis. Many of these protists can be found in a drop of pond or lake water.

<span>The organs of the urinary system work to help the body to get rid of wastes and excess water in the form of urine. The major organs of these system are; Kidney which remove wastes
Ureters which forces urine into bladder
Bladder; stores urine
Uretha that removes urine from bladder to outside of body</span>
Bio-Engineering is the use of living vegetation, either alone or in conjunction with civil engineering structures and non-living plant material, to reduce shallow-seated instability and erosion.
<u>Explanation:</u>
DEVELOPMENT OF BIO-ENGINEERING:
In Germany and Austria wishes to use the low-cost local materials and traditional constructions due to their Financial restrictions of pre-war years 1930's
ADVANTAGES OF BIO-ENGINEERING:
Re-establishing vegetation and store the hydrology from the surface to control of accelerated erosion.
Cost-effective treatments:
- landslides
- Roadside failures
- River stream banks
- mining reclamation.
EXAMPLE:
GRASS PLANTING
Usually planting the large grass clumps in lines across the slope.
Horizontal lines are used to increase the protection against erosion.
