Enzymes carry out the essential venture of lowering a reaction's activation electricity—this is, the amount of energy that has to be installed for the response to begin. Enzymes paintings by using binding to reactant molecules and maintaining them in such a manner that the chemical bond-breaking and bond-forming approaches take place more effortlessly.
An enzyme is a biological catalyst and is almost usually a protein. It hastens the fee of a specific chemical response inside the cell. The enzyme is not destroyed at some point in the reaction and is used time and again.

Question 28
A person who has PKU, a recessive genetic disorder,
А
inherited the allele for the trait from one parent.
B
inherited the allele for the trait from both parents.
С
is heterozygous for the trait.
ОО
D
will not pass the allele for the trait to his or her offspring.
Answer:
B
Explanation:
In order for one to have a recessive trait, both parents must carry the trait.
XX Xy= XX XX Xy Xy
Xy Xy= XX Xy Xy YY
XX XX= XX XX XX XX
yy yy= yy yy yy yy
Only the options in which both parents have the allele can pass it on. Only if there is no dominant allele will the trait be expressed, which can only be a yy recessive (since heterozygous would be dominant). Therefore, he will pass the allele on to his/her offspring.

Which cell specimen is a prokaryote?
A Cell 1
B Cell 2
C Cell 3
Answer:
Cell 3
Explanation:
One of the unique main characteristics that differentiates a prokaryote from a eukaryote is the absence of presence of nucleus in their cell, and where their DNA is found.
In prokaryotic cells, nucleus is absence. The DNA of prokaryote is not found in a nucleus, rather, it is contained in a region referred to as nucleoid.
Therefore, the specimen that does not have DNA in nucleus is definitely a prokaryote.

When a doctor needs to give someone a medication intravenously (through a vein), they dilute that medicine in a saline solution (salty water). Why would it be a bad idea for a doctor to mix the medicine with plain water? (Hint: Osmosis is the answer, but you’ll need to explain why.)
Answer:
it is because the blood cells will have too much water in them and they will burst.
Explanation:
there will be less salt inside the cells so all the water will enter the cells. if there is also salt present outside of the cell then the water and the electrolites(salt) will equalize between the inside and the outside of the cell.
