Answer:
competition
Explanation:
An ecological community is a naturally occurring group of native plants, animals and other organisms that are interacting in a unique habitat. Its structure, composition and distribution are determined by environmental factors such as soil type, position in the landscape, altitude, climate and water availability(Department of Agriculture).
A climax community refers to the last stage of ecological succession in which the community remains relatively unchanged unless it is destroyed by events such as fire or human interference.
Competition between species in the same habitat is an important biotic factor in discussing ecological succession and the emergence of climax communities. Competition leads to a drop in the diversity of species in a given ecosystem because the dominant species live on and reproduce while the other species die off.
Answer:
Bacterial genomes contain small transposable elements termed <u>Jumping Genes</u> that resemble transposons of eukaryotic cells.
Explanation:
Jumping genes are small parts of the DNA that program enzymes and move it from one DNA location to another, sometimes on the same molecule of DNA sometimes on another molecule.

Answer:
a selective medium, a differential medium, and a complex medium
Explanation:
EMB Agar (Eosin Methylene Blue Agar) is both a selective and differential culture medium that slightly inhibits Gram-positive bacteria and can be used to distinguish bacteria capable of fermenting lactose from those that are unable to ferment this disaccharide. This medium is commonly used for isolation and differentiation of coliforms (i.e., bacteria found in the soil and water samples) and fecal coliforms (bacteria found in the gut and feces samples). In EMB agar, lactose-fermenting-gram-negative bacteria (e.g., <em>E. coli</em>) will form colored colonies, while non-lactose-fermenting-gram-negative bacteria will form colorless colonies (e.g., <em>Salmonella</em>). EMB agar is composed of lactose, gelatin, methylene blue dye and eosin Y dye ( a xanthene dye)
