What factors affect the amount of solar energy that reaches the Earth’s surface?

umka2103 [35]

One of the factor is the Sun's elevation where the UV reaches us at a much lower frequency when the sun is more distant. Next is our ozone, with our ozone depleting as time goes by, the amount of solar energy it can diffuse is much lesser thus the heat is much more than the previous decades.

Answer:

a. conservative replication

b. semi conservative replication

c. dispersive replication

d. discontinuous replication

e. continuous replication

The CORRECT ANSWER IS C.

c. dispersive replication

Explanation:

The attached image shows a single band that becomes lighter (in volume) and increase in darker intensity (in times of color) is revealed with consecutive replications. The major pattern that would produce these outcome is dispersive replication.

Conservative replication do reveal two bands (a 14N for the wholly latest molecule, and a 15N for the totally antiquated molecule) after the initial replication. Therefore, this wholly wrong.

Semi-conservative replication reveal an individual band of transitional weight after the initial replication, followed by two bands following the second replication (one of transitional weight, and the other at the 14N position). These two bands is observed in each following replication, with the transitional weight becoming lighter in color as the 14N band is seen to appear darker in color.

The real pattern gives an individual band that pinpoints to all molecules in an individual replicative cycle possessing the same constituents.

Dispersive replication, has its molecules to be a blend of old (15N) and new (14N) strands. Each replication raises the ratio of new to old strands as it explains the reason an individual band is shown raised (lighter in weight) with every replication.

Anarel [89]

Answer:

option d, b, c

Explanation:

Starch molecules taken into the mouth from food substances are processed to an extent of 30% of its digestion. this is carried out by a specialized protein/ an enzyme that is present in the saliva; called amylase or ptyalin. this enzyme acts on the substrate molecule which in this case is starch molecules and convert it into smaller chains of simple sugars that includes maltose and dextrin which is digested in the small intestine.
