Answer:
Option C, The substrate for amylase, starch, is not present.
Explanation:
All the tubes (except one) were exposed to following three conditions -
a) a buffer of pH 6
b) a temperature of 104ºF (40ºC)
c) presence of starch
The only tube which was exposed to first two conditions but not the third one i.e starch, do not produce glucose because starch (substrate) was not available for enzyme amylase on which it can act upon under favorable conditions.
The reaction will start only when the enzyme meets the starch.
Answer: polypeptide, protein
Explanation:
Polypeptide -> two or more chains of amino acids joined together by peptide bonds
Protein -> one or more polypeptide

Answer:
the water evaporates and absorbs the heat from his body, that causes cooling and lowers his body temperature.
Explanation:
Answer:
small
Explanation:
The overall error rate of DNA polymerase during replication is 10-8 errors per base pair. Repair enzymes fix 99% of these lesions for an overall error rate of 10-10 per bp. That means one change occurs in every 10 billion base pairs that are replicated.
DNA replication is a highly accurate process, occurring rapidly and with a small number of mistakes, due to the efficiency of the DNA polymerase enzyme and the cell's repair mechanisms. However, any uncorrected mistakes can cause significant consequences, like mutations or even diseases like cancer. This process has been closely studied in prokaryotes such as E. coli.
DNA replication, a critical biological process, typically occurs with a remarkably small number of mistakes, thanks to the accuracy of the DNA polymerase enzyme and other repair mechanisms. This process has been particularly well-studied in prokayotes, like E.
coli, which can replicate its 4.6 million base pairs in about 42 minutes, adding around 1000 nucleotides per second.
However, when mistakes do occur and are not corrected, they can lead to mutations which might have serious consequences, such as cancer, particularly if the repair enzymes themselves are mutated or defective.

b. human
c. bacteria
d. fungi
Answer:
The answer is B. human.
Explanation:
Humans are classified in the species Homo sapiens belonging to the animal kingdom, whose cells are all eukaryotic cells that have isolated nucleus and nucleus membrane.
The eukaryotic cells of Animal make up animal tissues and differ from plant cells in that they lack cell walls and chloroplasts and have smaller and generally more abundant centrioles and vacuoles. Due to the lack of rigid cell wall, animal cells can take a variety of forms and can even phagocyte other structures.
