What is the difference between helicase and DNA polymerase?
Answer:
Just as helicase is responsible for unwinding the DNA strand, DNA polymerase is responsible for replicating the strand once it unwinds and separates. DNA is made up of a sugar-phosphate ladder and a nucleotide base.
Explanation:
Answer:
The Helicase unzips the DNA strands into two parts. The polymerase is an enzyme that synthesizes long chains of polymers or nucleic acids. DNA polymerase and RNA polymerase are used to assemble DNA and RNA molecules, respectively, by copying a DNA template strand using base-pairing interactions or RNA by half ladder replication.
Explanation:
So the Polymerase basically brings together/adds new DNA parts to a strand, making the 2 half strands into 2 full strands.

How are proteins used in mating by Japanese beetles
A. They build mitochondria from proteins
B. They use proteins to store lysosomes
C. They send proteins as chemical messages
D. They store proteins in the their large vacuoles
Answer:
C. They send proteins as chemical messages
Explanation:
In the case of Japanese beetles, the female is the one who attracts the pheromones that have a role in the mating. The pheromones are the chemicals that serve to get a social response from the same species.
The males, however, produce the protein that helps them discover the pheromones which afterwar is sent to the female with the goal of mating.
what's net free water movement
Answer:
the net movement of water across a selectively permeable membrane driven by a difference in solute concentrations on the two sides of the membrane
Explanation:
Answer:
The movement of water from an area of high concentration to an area with low water concentration.
Explanation:
The net movement of water (osmosis) is in the direction of increased solute concentrations. An easy way to visualize this rule is simply that the net water movement is from an area of high water concentration (little dissolved solute) to an area of low water concentration (high levels of solute).

What structural feature makes the abdominal musculature especially strong for its thickness ? it’s for anatomy
Answer: It’s like wood. The many abdominal muscles move in different directions across the abdomen which makes the abdomen wall very strong.
Hope this helps! :D
The structural feature that makes the abdominal muscular is ; The abdominal muscle running through the abdomen
The abdominal muscles covers/protects the internal organs found in the abdomen. they cut across the abdomen which makes the abdomen strong and muscular in nature.
The abdominal muscles are grouped into ( 4 ) distinct groups and they are :
Transversus abdominis Rectus abdominisInternal and external oblique musclesThe various groups of abdominal muscles perform various functions in the abdomen. e.g. Transversus abdominis is the deepest of all muscle layer which helps to maintain the internal abdominal pressure.
Hence we can conclude that The structural feature that makes the abdominal muscular is ; The abdominal muscles running through the abdomen.
