Sunlight striking the earth at an angle is stronger and hotter than direct sunlight striking earth? True or False
Sidana [21]

Answer:

True

Explanation:

Angle of Solar Radiation and Temperature

When the sun's rays strike Earth's surface near the equator, the incoming solar radiation is more direct (nearly perpendicular or closer to a 90˚ angle). Therefore, the solar radiation is concentrated over a smaller surface area, causing warmer temperatures.

Which of the following are common traits of chloroplasts and mitochondria?
Delvig [45]

Answer:

c. Both have their own DNA.

Explanation:

Both chloroplast and mitochondria are semi-autonomous organelles which means that they both have their own DNA. Both of these organelles have a circular DNA and make some of their own proteins by themselves. Both are double membrane-bound organelles. Chloroplast has a third membrane system called thylakoid.

Chloroplasts are found in the plant cells only as they are the site for photosynthesis. Mitochondria are present in both plant and animal cells and are the site for cellular respiration to produce energy to support the vital functions of cells.

Which protein is responsible for unraveling the DNA double-helix into 2 strands to prepare it for copying?
mr Goodwill [35]

The answer is; DNA helicase

They unzip the double helix into single strands during replication. The unzipping occurs at regions called origins where replication is initiated. The protein breaks the hydrogen bonds (using energy from ATP) between the complimentary bases of the strands hence forming a replication fork.
