Viewing the shape of a bacterial or archaeal cell using a microscope gives a great deal of information about the metabolism and
ivann1987 [24]

The information as stated is false.

<h3>What is a microscope?</h3>

A microscope is a device that could be used to view the interior of a cell. It is a device that uses light to show the interior of the cell. The magnification of the microscope is what determines how much information that you could get from it.

The first compound microscope was discovered by Robert Hooke and was used extensively in the study of cells and this is how the study of microorganisms became more elaborate.

Thus, it is false to say that viewing the shape of a bacterial or archaeal cell using a microscope gives a great deal of information about the metabolism and lifestyle of the organism.

Which of the following statements is true?
Lelu [443]

Answer:

The true statement is: "Spring tides are the highest, while neap tides are the lowest."

Explanation:

  • The range of difference in the level of water between high and low tide is always larger in spring tide.
  • Neap tides are the moderate tides. It does not have huge difference in higher and low tides because the bulging of the ocean ( by the sun)  balances the bulge of the ocean caused by the moon.
  • This balance is not found in spring tides that is the main reason for spring tides to have the highest level for both higher and lower tides.

How does synthesis of the leading strand differ from synthesis of the lagging strand during dna replication?
Alexandra [31]

Answer:

DNA replication is a process where the DNA is copied and replicates to produce the 2 identical copies of the molecule. Strands of DNA molecule work as a template for the production of complementary strands. The DNA splits synthesizing a fork. A new DNA is always synthesized in a 5' prime to 3' prime manner. Replication of both the DNA strands goes in two different ways.

1) Leading strands: It is a strand which is goes to the direction same as the replication fork movement and synthesized in 5'-3' prime direction. This strand formation is occurred as nucleotides are continuously added to the 3' prime end after polymerase reads the DNA template (original).

2) Lagging strands: It is a strand which is goes to the opposite direction as the replication fork movement and synthesized in 3'-5' prime direction. It is synthesized in fragments which are known as okazaki fragments. Lagging strand synthesis needs RNA primase.
