C. is essential in the synthesis of dna and in the development of red blood cells.
Answer:
all of these are echinoderms
I think the answer is "the older it is"
Reason: I might be wrong but is something (like a shell) gets buried in something (like sand), overtime many things (like dirt, soil, sand, etc.) will be on top of the original. This will make layers. So, the older rock is on the bottom since it has been there for the longest and it gets covered by other stuff (causing the layers).
Hope this helps! :) (If I'm wrong, sorry :( )
Answer:
There is no image showing the shape of an enzyme, however, the question can still be answered based on basic understanding. The answers are;
- Less binding of substrate
- won't follow the lock-and-key pattern of enzyme binding
Explanation:
An enzyme is a biological catalyst that regulates the rate of chemical reactions in living systems. Enzymes are proteinous in nature and every protein is made up of an amino acid sequence. The amino acid sequence forms a three-dimensional shape that determines the functionality of the enzyme.
Enzymes catalyze reactions by binding to their substrates in a lock and key pattern. This makes enzymes substrate-specific. If the enzyme's normal shape changes, the following will occur:
- Less binding of substrate
- won't follow the lock-and-key pattern of enzyme binding.
Bioaccumulation refers to the accumulation of a toxic chemical in the tissue of a particular organism.
Biomagnification refers to the increased concentration of a toxic chemical the higher an animal is on the food chain.
