Enzymes are catalysts, meaning that they are proteins that speed up reactions. So without them, there would be barely any activity.
Flatworms (Platyhelminthes) are phylum of unsegmented, soft, flat invertebrates.
Flatworms have no body cavity which is why they are flat. The advantage of a flat body is facilitated respiration and circulation. Flatworms do not have respiration and circulation system. But, oxygen diffuses across the skin and reach all parts of the body thanks to a flattened shape. Also, it is easy to hide from predators because they can get almost everywhere thanks to the body shape.
Answer:
4
Explanation:
According to newton's second law f=ma. so a =f/m
then a=20/5 gives 4
Answer: Seral stage
Explanation:
The seral community commonly known as sere. It is an intermediate stage which is found during the ecological succession in an ecosystem.
This is an intermediate stage that comes before every stage of ecological succession advancing towards its climax community.
It starts with the pioneer species and keeps on evolving until climax community is attained.
Hence, the correct answer is option C
Answer:
Photosynthesis
Explanation:
Atmospheric carbon dioxide is converted to glucose during the Calvin-Benson cycle. This requires the overall reduction of CO2, using the electrons available from the oxidation of NADPH. Thus the dark reactions represent a redox pathway. NADPH is oxidized to NADP+ and CO2 is reduced to glucose.
