rodikova [14]

Answer:

The correct answer is C

Explanation:

Allosteric enzyme is an enzyme that has more than one active site on the surface of the enzyme. Generally, the binding to one of these active sites affects the affinity of the other active sites on the enzyme; this causes the enzyme not to follow the Michaelis-Menten's enzyme kinetics. Thus, <u>when the activity versus substrate is plotted on a graph, a sigmoidal curve shown instead of an hyperbolic curve (like other enzymes)</u>.

The nitrogen cycle is most directly dependent upon-
vovangra [49]

Answer:

B) Nitrogen-fixing bacteria and lightning

Explanation:

Nitrogen cycle is the natural process in which atmospheric nitrogen is converted into nitrite and nitrate with the help of bacteria.

Nitrogen cycle is directly dependent on nitrogen-fixing bacteria and lightning.

As bacteria are responsible for most of the chemical conversion in the nitrogen cycle such as nitrogen fixation (first step) is done by soil bacteria (Cyanobacteria) that form ammonia, which is toxic to plants; nitrification in which ammonia is converted into nitrites and nitrates with the help of Nitrobacter and denitrification bacteria involve Pseudomonas, and Achromobacter which convert nitrite and nitrate into nitrogen.

The lightning breaks nitrogen molecules and allow  it to combine with oxygen in atmosphere which further dissolve in rain and form nitrates.

Hence, the nitrogen cycle is most directly dependent upon nitrogen-fixing bacteria and lightning and the correct option is B.

Are flowers counted as an asexual reproducer?
True [87]

Answer by YourHope:


Are flowers counted as an asexual reproducer?


It all depends on the flower. Flower plants are capable of sexual reproduction. However, they vary on whether they can reproduce both ways, or only sexually.
