When would your cells be most likely to use fermentation instead of aerobic respiration?.
Answers
When you are exercising.
In everyday life when you aren't doing physical activity, you get enough oxygen to move. However, when you are exercising, you're using more oxygen than how much you're taking in. When the body doesn't have enough oxygen, (when you are exercising) it switches to anaerobic respiration (or fermentation).
Hope this helps!
During exercise, the cells of the body demand more energy so they use fermentation instead of aerobic respiration and lactic acid is produced from glucose.
What is fermentation?It is the process of partial oxidation of glucose, carried out by muscle cells when they run out of oxygen to breathe.
This process generates ATP but produces lactic acid as a by-product, which, when accumulated, produces the painful sensation of muscle fatigue during exercise.
Therefore, we can conclude that during exercise, the cells of the body demand more energy so they use fermentation instead of aerobic respiration and lactic acid is produced from glucose.

3.Why do coral reefs have such a high biodiversity?:
1- they have many different niches
2- they are found in northern latitudes
3- they are found in deep, warm waters
4- they have an unusually uniform habitat
Answers
Explanation:
1.What happens as the number of niches in an ecosystem goes up?:
Biodiversity increases- As the number of niches increases, I suppose there would be more competition for space
2.What group of organisms has the greatest number of species?
insects-In terms of numbers of species, insects certainly represent the largest percentage of the world's organisms. There are more than 1 million species of insects that have been documented and studied by scientists.
3.Why do coral reefs have such a high biodiversity?
they have many different niches-High biodiversity ensures the health of the reef. It spreads those roles across many species, so if one species is affected by a disease or other threat, that role won't be lost on the reef.

In any population, some individuals will have more kids than other individuals (just by chance). Some of those individuals will be "lucky" and survive. Explain the cartoon and how it shows this idea.
Answers
Answer:
By people stepping on the little bugs, it kills them. and when they are born some will die and others won't
Explanation:
The cartoon refers to the principle of natural selection, which operates in many species, including bugs.
When individuals of a species reproduce, their offspring inherit certain traits or characteristics that can be advantageous or disadvantageous. In the case of bugs, some may have stronger exoskeletons, faster reflexes, or better camouflage, which can help them survive being stepped on or avoid being noticed by predators.
As a result, those bugs with advantageous traits are more likely to survive and reproduce, passing on their favourable characteristics to the next generation, while those without these traits are more likely to die. This is an example of natural selction.

Bees are common pollinators, and many commercially grown crops that we eat depend on bee pollination Bees' eyesight allows them to be such successful pollinators. They have two sets of eyes. At the top of their heads, bees have three smaller eyes (called ocelli) that help them discern light intensity, maintain stability, and navigate. They also have two large compound eyes that detect movement Bees can see ultraviolet (UV) light with their ocelli. Thus, vibrant ultraviolet colors and pattems in flower petals are visible to bees but invisible to us. These pigments often direct the bee to specific parts of the flower (eg, the flower's center). Additionally, their remarkable eyesight allows them to visualize objects at high speeds. For example, while you might see a blur of color if you quickly drove past a meadow, a bee could easily visualize individual flowers in the meadow without reducing its flight speed.
Given this information, consider why these characteristics may have evolved in the bee.In three to five sentences, describe these factors
• how one of these characteristics would benefit the bee .
