Biological weathering is caused by living organisms, such as microbes, animals, and plants. Water, oxygen, and rocks are nonliving things (though water and rocks may be capable of weathering), and only plant roots fits the definition of biological weathering. So the correct answer for #1 is A.
Frost wedging occurs when the little water content in rock freezes, expanding and forcing the rock apart. Eventually, enough freeze-melt cycles causes the rock to break apart little by little. This is due to ice's density being less than that of water, meaning that it is because water expands when frozen. So the answer to #2 is A.
Answer:
Ellen gave 24 inches of her ribbon to the friend.
Explanation:
The total length of ribbon Ellen has = 20 feet
Used to make pillows = 12 feet
Remaining ribbon = 20-12 = 8 feet
Given to her friend = 1/4
1/4 of 8 = 1/4 × 8 = 2 feet
so she gave 2 feet of ribbon to her friend.
- As there are 12 inches in 1 foot.
so
2 feet in inches = 24 inches
Therefore, Ellen gave 24 inches of her ribbon to the friend.

A possible cause was a meteorite hit the earth. it caused many organisms to become extinct because it blocked out the Sun so plants couldn't grow and herbivores couldn't eat the plants and carnivores couldn't eat herbivores.
