The correct answer is - Theory of the Ekman spiral

V. W. Ekman or Vagn Walfrid Ekman was a Swedish physical oceanographer. He is famous for his studies of the dynamics of ocean currents. Ekman developed a theory called as the “theory of the Ekman spiral”. This theory explains maintaining balance between frictional effects in the ocean and the Coriolis force. The force arises from moving objects in a rotating environment such as planetary rotation.

At 20°C the enzyme that catalyzes the breakdown of polysaccharides functions at 1 reaction every 20 microseconds. If this enzyme

lora16 [44]

Answer:

Seven segments

Explanation:

As given in the question -

After every twenty microseconds one reaction occurs i.e breakdown of polysaccharides.

This means that after every twenty microseconds the polysaccharides is broken down

The total time for this hydrolysis reaction is $120$ micro seconds

Thus , there will be six phases of division each after every twenty microseconds

After 1st twenty microseconds , total segments is equal to two

After 2nd twenty microseconds , total segments is equal to three

After 3rd twenty microseconds , total segments is equal to four

After 4th twenty microseconds , total segments is equal to five

After 5th twenty microseconds , total segments is equal to six

After 6th twenty microseconds , total segments is equal to seven

DNA replication of chromosomal DNA in a cell requires all of the following, EXCEPT A) DNA polymerase B) primase C) helicase D) R

Viktor [21]

Answer:

The correct answer is D)RNA polymerase

Explanation:

In DNA replication many enzymes and proteins are required to replicate a DNA template. For initiation of DNA synthesis the two DNA strands must be separated which is done by helicase.

Then primase adds short nucleotide sequence and initiate DNA replication. After that DNA polymerase acts and adds nucleotide at the 3' end of growing DNA strand. Ligase is the enzyme that joins the two Okazaki fragments that are created in the lagging strand.

RNA polymerase is not required in DNA replication and it works in transcription therefore the correct answer is RNA polymerase.

Use the drop-down menus to put the events of the light-dependent reaction of photosynthesis in the correct order.

mash [69]

Events of the light-dependent reaction of photosynthesis starts with the absorption of sunlight and ends with ATP production.

<h3>Events of light-dependent reaction</h3>

In the first step energy is absorbed from the sun and then water is broken down.
Hydrogen ions of the water molecules are transported across the thylakoid membrane.
NADPH is produced from NADP+.
Hydrogen ions diffuse through the protein channel.
ADP turns into ATP.

Explain how the wind may be involved in the formation of sandstone arches.

WITCHER [35]

Answer

Wind may be involved in the formation of sandstone arches by facilitating erosion which wore away exposed sections of rocks and enlarges the cracks on the surface forming marrow sandstone fins.

Explanation

Sandstone arches can be formed when a large piece of sandstone flaked off as a result of high winds. In addition to that, alternative frost and thawing can result into crumbling of porous sandstone which will in the long run cut through some fins. These resulting holes enlarge to form arches with effects of weathering and rock fall caused by wind.
