The answer is: It is an explanation for an observation.
Explanation:
A hypothesis is a suggested explanation that is both testable and falsifiable. You must be able to test your hypothesis, and it must be possible to prove your hypothesis true or false.
Answer: a) substrate and cofactors b) covalent modification
Explanation:
Metabolic pathways involve all the chemical processes takes place in the enviornment or in an organisms.The metabolic pathways are controlled through the catalytic activities of enzymes.
The availability of enzyme is regulated by substrate and cofactors present in enzyme and enzyme activity is commonly regulated via covalent modification.
Enzymes are highly selective in nature and bind to a specific substarte only. The active site in enzyme binds with the substrate to form enzyme substrate complex. Coactors assist the enzyme activity, without cofactor enzyme can not perform its activity.
Hence enzyme availibility is regulated by substrate and cofactors regulates.
Covalent modifications regulates activity of enzyme as it involves addition and removal of chemical group to synthesis required protein. It can change the chemical properties of the site by targeting one or multiple amino acid.
Thus the correct answer is a) substrate and cofactors b) covalent modification
Answer: Cells have specific jobs they have to do, like for example, reproduction, cells help in the reproduction of organisms. Energy metabolism, some cells help with nutrients and oxygen. Regeneration, if you get a cut or a scrape, some cells help to heal that wound. And information transfer, this is when we get information in our brain.
Hope this helps!
A geochemical cycle is the pathway that involves the movement of elements or substances in the Earth's surface and the crust. I believe the answer are hydrologic, heat, and rock. These are the three main geochemical cycles of the Earth and are responsible of continuously removing and adding materials here on Earth.
Answer:
Hotter temperatures and moving climate examples can decline air quality, which can prompt asthma assaults and other respiratory and cardiovascular wellbeing impacts. Out of control fires, which are required to keep on expanding in number and seriousness as the atmosphere changes, make smoke and other undesirable air pollutants.
