Explain why do you think most energy pyramids have less than five levels?

Biology
1 answer:
zlopas [31]3 years ago
4 0
The amount of energy available as one moves up the energy pyramid decreases substantially.
Explanation:
At each trophic level, energy is lost primarily through heat loss and respiration.
In the image below, 100% of the energy from the plant is not available to the deer. As we move further from the primary producer (in the image below, the green plant), less and less energy is transferred.

When setting up a Sanger sequencing reaction, each reaction should include template DNA, nucleotides, dideoxynucleotides, buffer
kondaur [170]

Answer:

b. Forward or reverse primers

Explanation:

Sanger sequencing is a technique of DNA sequencing based on the extension of DNA fragments with variable sizes terminated with dideoxynucleotides at the 3′ end. This technique was developed by Frederick Sanger in 1977. In Sanger sequencing, a short primer is added in order to bind by complementarity to the target DNA region of interest. Subsequently, a DNA polymerase adds nucleotides (A, T, C and G) in the 5'-3' direction. Finally, the extension of the DNA strand is stopped by adding dideoxynucleotides, which are nucleotide analogs (i.e., modified nucleotides) that act as DNA synthesis terminators.

Muscles that move the eyeball have ________ fibers.
ozzi

Muscles which are responsible for the movement of the eyeball have fast fibers. Thus, the correct option is A.

<h3>What are fast muscle fibers?</h3>

Fast-twitch muscle fibers are the muscle fibers which provide bigger and more powerful forces, however for shorter durations and fatigue quickly. They are more anaerobic with less blood supply, and hence are sometimes also referred to as white fibers or type II fibers.

Fast-twitch muscle fibers are activated by the high intensity movements which are sustained in short bursts. Examples of movements include sprints, burpees, and quick lateral movements.

Therefore, the correct option is A.
