Answer:
D. Enzymes only break down large molecules.
Explanation:
Enzymes are the substances which helps in the broken down of large food molecules into small molecules. It is because our body is not able to absorb large food molecules, these large molecules are broken down into small molecules with the help of enzymes. Carbohydrate is broken down into glucose by amylase and protein is broken down into amino acids by protease. Enzyme is non-living in nature and used as a catalyst in order to speed up the chemical reaction.
Well for starters, producers are living organisms that produce their own food. Like plants. And plants ironically provide us humans with oxygen as they live off of the carbon dioxide we produce. Some plants are also main vegetables that we eat, so put simply, a world without producers would be practically oxygen-less and vegetable-less.
Answer:
The appearance of free oxygen in the Earth's atmosphere led to the Great Oxidation Event. This was triggered by cyanobacteria producing oxygen which developed into multicellular forms as early as 2.3 billion years ago
Explanation:
To clarify what I said here are some questions to help!
How did oxygen first appear?
Whiffs in the air is how oxygen first appeared billions of years ago.
For the most part, scientists agree that oxygen, though lacking in the atmosphere, was likely brewing in the oceans as a byproduct of cyanobacterial photosynthesis as early as 3 billion years ago
When was oxygen found?
2.33 billion years ago
Since its first appearance 2.33 billion years ago, oxygen accumulated in high enough concentrations to have a weathering effect on rocks just 10 million years later.
I don't know if this helped you but if it does, please let me know!
Answer:
The right answer to this question is Yes
Explanation:
These new bugs can still get resources, and these resources will maintain them alive, when the old ones will not survive because they are depleted. And with that, we can be sure that, the ones with less development won't get the resource they need to survive. And after that, when they die, the dispersing bug will be more common in this place because of the Natural Selection.
