Answer:
Enzymes function best at specific pH and temperatures.
Explanation:
An enzyme can be defined as a biological catalyst that typically lowers the activation energy of a biological reaction. When the activation energy of a reaction is low, the rate of the reaction would be faster. Therefore, an enzyme speeds or catalyzes the rate of a reaction by lowering its activation energy.
Also, if the conditions are not optimal for an enzyme, it limits the ability of an enzyme to bind or be joined with its substrates.
Hence, the correct statement about enzymes is that enzymes function best at specific pH and temperatures. An increase in temperature increases or speeds up the rate of a reaction while low temperature limits or reduces the rate of a reaction. The optimal temperature for enzymes in the human body is around 37 degrees celsius.
Gametes are reproductive cells that unite during sexual reproduction to form a new cell called a zygote. Sexual reproduction needs zygotes to reproduce that is why gametes are needed. Asexual reproduction doesn’t need gametes because there is only one parent and there is no fusion of gametes.
Answer:
D. Water
Explanation:
the covalent bonds of water are stronger than the ionic bonds in the salt molecules so they dissolve.
Answer is A Sunlight because the grass are staying in the shade which they’re not getting sun light
Answer:
The process of DNA replication allows for information to be retained that same way as a Flash drive does files. It copies them, and downloads them somewhere else, while keeping them on the drive until terminated. I don't know if this answered your question the way you wanted, but this is how my teacher expalined it in like the 5th grade
