gy transformation(s) is/are depicted here?
A) electrical energy ⇒ light energy
B) potential energy ⇒ kinetic energy ⇒ light energy
C) chemical energy ⇒ electrical energy ⇒ light energy
D) chemical energy ⇒ electrical energy ⇒ heat and light energy

A) It was lost due to friction.
Eliminate
B) It was transformed into 350 J of heat energy.
C) It was destroyed by the rotating blades of the fan.
D) It was never used and therefore was not transformed

The rate limiting reaction of aerobic respiration involves the phosphorylation of __________ by the enzyme _______ . The rate at
Ahat [919]

Answer:

Explanation:

The rate limiting reaction of aerobic respiration involves the phosphorylation of fructose phosphate by the enzyme phosphofructokinase. The rate at which this enzyme makes product is [increased, decreased] when ATP levels rise because the molecule ATP binds to an allosteric site on the enzyme and acts as a direct inhibitor. When ATP levels fall AMP binds to the allosteric site of phosphofructokinase. This interaction leads to an increase of cellular ATP, so that this is an example of a negative feedback loop.

Antelopes and elephants feed on the same species of grasses and shrubs in a savanna and the fitness of each species is reduced w
34kurt

Interspecific competition occurs between antelopes and elephants.

The term "competition" refers to the process that takes place among many species as they fight for the same limited resources in order to maintain their own existence. This struggle over resources occurs among organisms because these species occupy niches that overlap, and as a result, they are compelled to use the same resources like food, water, and shelter.

Competition can be either interspecific or intraspecific. The term "interspecific competition" refers to a type of competition that occurs between various species that live in the same biological area and are dependent on the same source of food.

In the question, both antelopes and elephants feed on the same grass and shrub species. Therefore they compete amongst themselves as a result of which their fitness is reduced.
