jeka94

The answer is: Ecological Succession

STEPS:
1.) Bare rock (there is no grass at this point).

2.) Lichens (lichens begin to appear).

3.) Small Plants & Lichens (small plants begin to grow & the lichens are spreading).

4.) Grasses (grass starts to grow in certain spots).

5.) Shrubs & Grasses (the grass has covered, at least the majority, of the ground and shrubs begin to appear).

6.) Trees (the shrubs have grown into trees that are tall enough to provide shade)

7.) Animals (the animals return or new animals appear).

In a transformation experiment, a sample of E. coli bacteria was mixed with a plasmid containing the gene for resistance to the

brilliants [131]

Answer:

The correct answer is option A. demonstrates that the E. coli cultures were viable.

Explanation:

In this lab experiment or culture, Plate I and plate III demonstrate, that E.coli bacteria can grow both in the presence and absence of plasmid DNA if ampicillin is not there.

So, which means that plasmid DNA is not required for the growth of E.coli in absence of ampicillin. The presence of growth in wild type (plate 1) and a plasmid containing bacteria (plate 3) in media without ampicillin shows that bacteria are viable in nature.

Differences between plasmolysis and haemolysis ?

mash [69]

Plasmolysis is an effect of osmosis in plants. Osmosis is the net diffusion of water across a selectively permeable membrane, such as a cell membrane, from an area of higher water concentration to an area of lower water concentration.

Hemolysis is the breaking open of red blood cells and the release of hemoglobin into the surrounding fluid

Both are cause by osmosis
