Answer:
There are two possible answers: Deep-sea vents provided the energy needed for the first organic compounds to form OR self-replicating RNA molecules passed on genetic information.
Explanation:
The reason for the first answer is due to the hypothesis that indicates that life (organic molecules) arose from inorganic molecules synthesized from the amino acids in those energy vents. This is called the metabolism first hypothesis. The Miller-Urey Experiment provided evidence that organisms could rise from inorganic molecules (they simulated under the conditions you would see on early Earth). The second hypothesis is the RNA World hypothesis (second answer) which suggests that the formation of RNA that could replicate (possible due to mutation or evolution), led to life that could preserve its genetic integrity through replication (greater stability to the organism) and create lipid bi-layer membranes/other organelles. Some scientists support the Metabolism First Hypothesis, while others are skeptical (this goes for the RNA World Hypothesis as well). However, the RNA World Hypothesis is for more reasonable in the fact that its main point is the fact that RNA molecules were able to replicate and maintain genetic stability despite early Earth conditions. Although either hypothesis could explain why all organisms share the same genetic code, the RNA World Hypothesis better explains the universality of DNA/RNA of genes that we see today.
Answer:
Explanation: Members of Kingom Plantae are autotrophs, meaning they produce their own food via photosynthesis. They are multicellular organisms. On a cellular level, members of Kingdom Plantae have cell walls ( members of Kingdom Animalia lack cell walls in their cells, but have red blood cells instead)
Large blue whales that are up to 30 meters long live primarily on krill that is/are only about 6 cm long.
Blue whales belong to the class of mammals. They are the largest animals on the Earth. They live in marine habitat. They can be more than 100 feet long. The weight of a single whale can be equal to 30 elephants. And they can live for as long as 80-90 years.
Krill are small animals belonging to the class of crustaceans. They are present in oceans. Krill are actually zooplanktons. They are majorly the food of whales. Krill are filter-feeders.

Answer and Explanation: In enzyme kinetics, one constant describing enzyme activity is <em>Maximal Velocity</em> (Vmax). It indicates how fast an enzyme can catalyze the reaction. It is dependent on substrate concentration.
As the muscle is an organ which needs a great amount of energy, the enzyme glycogen phosphorilase is very active on the organ, compared to the liver, where glicose is stored. So, the Vmax of glycogen phosphorylase expressed in muscle is faster than when expressed in the liver, means the enzyme in muscle has a bigger concentration of substrate and therefore will reach Vmax faster, i.e. will be significantly larger.
