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.
Answer:
Nutrients get absorbed as the food is broken down, with the majority of nutrients being absorbed in the small intestine, where they're then transported into the blood stream
Explanation:
Answer:
e
Explanation:
generate energy from the cell
In the complete reactions of aerobic respiration, the vibration for the majority of ATP synthesis is provided bt a proton gradient across a membrane.
The proton gradient brings by the electron transport chain drives ATP synthesis by the protein ATP synthase.
Answer:
atoms (2), community (11) , biome (13), biosphere (14), cells (5), organism (9), ecosystem (12), molecules (3), organ (7), organelles(4), organ system (8) , population (10), subatomic particles(1), and tissues (6)
Explanation:
Levels of organization in order from the simplest to the most complex are:
- Subatomic particles-neutrons, protons and electrons that make up the atom.
- atoms- Smallest particle of a substance that may or may not exist freely.
- molecules- two atoms combine to form molecule. e.g H₂
- organelles- organelles are functioning structures of a cell. e.g. Golgi apparatus.
- cells- organelles combine to form cell. e.g. Parenchyma cells.
- tissue- cells of similar origin and function form the tissue e.g. Cardiac tissue
- organ- tissues combine together to form organs. e.g. Heart
- organ system- many organs combine together to form system. e.g Circulatory system
- organism- several organ system combine to form an organism. e.g. Human being.
- population-organism of same species form a population.
- community- different population combine to form a community.
- ecosystem- communities live in a particular area and interact with the abiotic as well as biotic factors of that area to form ecosystem. e.g. pond ecosystem
- biome-A geographical area where several ecosystem sharing same abiotic factors thrive.e.g. tiaga biome
- biosphere- Narrow zone of the earth where the atmosphere , hydrosphere and lithosphere meet to support life.
