Answer:
The answer is only about 40
Explanation:
Whenever something is consumed, only about 10% of the energy is consumed. So when a primary consumer eats the producer, they will get about 4,000 kcal. Then the secondary consumer will get about 400. Finally, the tertiary consumer will only get about 40. Basically, just multiple the original number by 0.1 for every time it goes through consumption.
Mitochondria and chloroplast have similar DNA, which is not evidence for the endosymbiotic origins of mitochondria and chloroplasts.
According to the endosymbiotic theory, a chloroplast and a mitochondria were the independent prokaryotes. Both can be ingested by a large prokaryote and resist digestion. As a result, they continued as endosymbionts and eventually lost some of their autonomic properties. They divide by binary fission, have their own genetic material, possess 70s ribosomes, and Both include their own transcriptional and translational machinery.
Therefore, considering endosymbiotic origin theory, Both Mitochondria and chloroplast have similar DNA is not a piece of evidence.

Serve to transfer signals between cells.
Explanation:
Intercalated disc also called gap junctions are structural formations that are located between the myocardial cells of the heart. They help to bond or connect cardiac cells fibers together. They also help in cell to cell communications and propagate action potential. They serve to transfer signals between cells.
