Answer:
The number of cell divisions is too large to even estimate.
Explanation:
Think, for every cell to be formed, a parent cell needed to divide. on top of that, for every parent cell is the result of another parent cell. Think of how small a cell is, and think of how many cells are in the onion. The fact that onions are still onions is incredible, because a DNA mutation occurs at a very high rate during cell division. When DNA divides, it sometimes doesn't divide evenly, resulting in too much DNA is one cell, and not enough in another. Science has proven that the composition of DNA is what makes humans humans, trees trees, and onions onions. The fact that onions have withstood the millions upon millions of DNA mutations while still remaining a species, is astonishing.

Answer: The sun
Explanation: Primary producers obtain their energy via the sun through the process of photosynthesis.
Answer:
Mechanisms are activated where it is sought to lower the amount of free protons in the blood, that is, to reduce acidity, these mechanisms work between two large systems, the receptor system, the respiratory system and the renal system.
Explanation:
When a metabolic acidosis is entered, either by a food, or by a disease or even an intense physical activity, the lungs seek to generate hyperventilation, to increase the concentrations of oxygen in plasma and absolutely decrease the carbon dioxide concentration, thus not the blood becomes even more acidic.
On the other hand, the digestive system together with the sensory system, will warn this proprioception of the acidity of the plasma and will promote the dilution of these acids with a solvent, which is water, promoting the sensation of thirst.
Finally, the kidneys will seek to retain all the alkaline solutes to neutralize the physiological internal pH, and will release through the urine and the channels of acidic compounds, the products or acid metabolites to the external environment, that is, acid urine excretion.
Answer:
Introduction Purpose: Explore the interdependence of organisms by
performing an experiment with lima bean plants and earthworms. Question: How can the presence of one species benefit another in
the same ecosystem?
Hypothesis: If plants grow in soil containing worms, then the
plant growth will be greater, because worms help decompose organic matter and distribute it through the soil in a form that plants can use.
