Answer:
Like bees and other pollinators, butterflies pick up pollen while they sip a flower's nectar. Once they're off to another plant, the pollen goes with them, helping to pollinate the plant species.
Explanation:
Answer:
Diffusion
Explanation:
The process by which substances move from areas of higher concentration to areas of lower concentration is called diffusion.
For example:
Substance moves across a cell membrane without using the cell's energy tends to move away from the area where it is more concentrated.
It is known as passive transport.
It is the process in which substance without using the cellular energy tend to move down the concentration gradient.
It is also known as simple diffusion.
When perfume bottle is open particles spread in air due to difference in concentration from bottle to out side environment.
While,
In case of active transport substance move against the concentration gradient i.e to wards the area of higher concentration.
This process require energy.
Climate change due to the greenhouse effect.
Answer:
A. When oxygen levels within a cell are too low for aerobic respiration
Explanation:
Fermentation is a chemical or metabolic process that occurs in organism, when a carbohydrate such as glucose is metabolized or converted to an alcohol anaerobically (absence of oxygen).
When an organism lacks oxygen within the cell, aerobic respiration would be halted, hence pyruvate produced from glucose further undergoes fermentation anaerobically.
Organisms like lactic acid bacteria and yeast carry out fermentation. The process of fermentation is widely used in food industries, such as in brewing of wine or manufacture of yogurt.
