I am sure that the answer is A.) Hierarchical Classifications. I hope that I'm right because this will affect you instead of me! But just in case, check this website. It says that a major contribution was Hierarchical Classifications before Binomial Nomenclature.

Answer:
In a population, a specific gene has two alleles, 'A' and 'a.' Individuals with
genotype 'aa' die in early childhood. Individuals with genotype 'Aa' have a
higher rate of surviving and reproducing than individuals with genotype 'AA.'
This phenomenon is called survival of the fittest, Darwins law which entails the fittest organisms survives while the ones that could not would go into extinction
Explanation:
Answer:
Muscle cells, especially heart muscle cells and fat cells have the most mitochondria in the human body.
Explanation:
Mitochondria, the powerhouse of the cell is an organelle where cellular respiration occurs. They supply energy to the cells for their functioning. The number of mitochondria in a cell vary depending on the energy requirement of that cell.
Muscle cells are very active in our body and need energy for the movement. Heart muscle cells require a lot of energy to contract and pump blood through the circulatory system all the time. So they have a lot of mitochondria to produce a vast amount of energy they need.
The correct answer is A. some energy is wasted as heat.
Energy is transferred between organisms through the food in a food chin. Food chain begins with producers. They make food using solar energy. They are eaten by primary consumers which are in turn eaten by secondary consumers and so on. Large amounts of energy are lost from the ecosystem when energy is transferred from one organisms to the next. In biologic systems, large amount of energy is lost as metabolic heat when the organisms are consumed by the next level.
