A corn seed is genetically modified to be resistant to drought. What phenotype is observed to ensure the seed is engineered correctly?(1 point)

A. Color of corn

B. Degree of wilting

C. Size of the corn husk

D. Weight of corn kernel

I'm not sure... A?

No, the color of the corn is not necessarily related to drought resistance. The correct answer is B - the degree of wilting would indicate whether the genetic modification for drought resistance is effective.

How can fossil fuels extracted from Earth's surface be used in households and businesses? (1 point)

A. as coal to heat a stove

B. as paper to write a note

C. as solar energy to power lights

D. as liquid soap to wash hands.

I chose A, but I think it's C.

No, the correct answer is A - fossil fuels such as coal, natural gas, and oil can be burned to produce heat or electricity for households and businesses. Option C is incorrect because solar energy is not a fossil fuel derived from Earth's surface, but rather a form of renewable energy. Option B and D are also incorrect as fossil fuels cannot be used as paper or liquid soap.

That's why I said I chose A.

I apologize, you are correct, you did choose A. My mistake was assuming A was incorrect. You chose the correct answer. My apologies for the confusion.

Which demonstrates the use of a single product in different settings?(1 point)

A. Rain falls in a gutter and flows down a pipe.

B. A pile of objects are thrown away as garbage.

C. Sunlight is trapped by solar panels to power a house.

D. A metal chair begins to rust outside.

The correct answer is C. Sunlight can be 'used' or captured by solar panels to power a house or other settings. A single product, in this case sunlight, is being utilized in different settings to provide energy. Options A, B, and D do not demonstrate the use of a single product in different settings.
