Answer;
Endosymbiotic theory is important as it explains the origin of the chroloplast and mitochondria. It also explains the formation of the eukaryotic cells.
Explanation;
Endosymbiotic theory explains the origins of eukaryotic cell organelles such as mitochondria in animals and fungi and chloroplasts in plants.
Mitochondria and chloroplasts are believed to have developed from symbiotic bacteria, specifically alpha-proteobacteria and cyanobacteria, respectively.
Answer:
Beginning the age of European exploration
Explanation:
A food web shows multiple pathways of energy flow through the ecosystem
Abundant amount of amino acids made up a polypeptide
The horse and mouse are endotherms among them rat will have high mass-specific metabolic rate.
The shark and fish are endotherms among them fish will have high mass-specific metabolic rate.
Explanation:
The endotherm (heat requires in them to maintain internal temperature of the body) organism have high metabolic rates to maintain homeostasis, this requires the large amount of energy. Smaller animals have the greater surface area to volume ratio, hence more heat loss and higher metabolism. In larger animals body volume increases, surface area increase is also very slow, hence less heat loss and lower Metabolic rate. Smaller animals exchange oxygen to tissues at a high rate.
Same goes with ectotherms the larger the animal the smaller is the metabolic rate. During winters their activity slows down as they cannot adjust with the temperature of the surrounding.
However metabolic rates of ectotherm and endotherm cannot be compared.
