Since I will have a science test next week based on these questions but my teacher won't check all answer with the class. I don't want to make a mistake and study to an incorrect answers. Do you mind to check the answers for me so that I am able to see if I got it correct or not. Thanks :)
Q1. There is a relationship between breathing and cellar respiration. Breathing involves taking in oxygen and releasing carbon dioxide. How is oxygen related to process of cellular respiration?
A. Cellular respiration uses ATP to release the energy stored in oxygen.
B. Cellular respiration uses oxygen to release the energy stored in food.
C. Cellular respiration uses oxygen to produce food in form of sugars.
D. Cellular respiration uses carbon to produce energy in the form of oxygen.
My Answer to Q1 is "C".
Q2: Plant cells produce their own food. They also must get energy from this food, which they use for cell activities, growth, and reproduction. What is the name of the process in which plant cells use oxygen to get energy from food?
A. photosynthesis
B. cellular respiration
C. fermentation
D. mitochondrion
My answer to Q2 is "B".
3. Worms break down dead plants in the soil, and in the process they release nutrients back into the soil. Which property of nutrients shows that they are a type of matter?
A. Nutrients are colorful.
B. Nutrients can do work.
C. Nutrients contain energy.
D. Nutrients have mass.
My answer to Q3 is "C".
I disagree with 3.
I believe Q1 would be B.
I read the chapter one more time and I'm guessing the answer of Q3 is "D"? (Having mass and taking up space are two characteristics of all matter.)
To check the answers to these questions, we can go through each option and determine if it is correct or not based on our knowledge of the topic. Let's go through each question and its options.
Q1. The question asks how oxygen is related to the process of cellular respiration. The correct answer to this question is B. Cellular respiration uses oxygen to release the energy stored in food.
Q2. The question asks what is the name of the process in which plant cells use oxygen to get energy from food. The correct answer to this question is B. Cellular respiration.
Q3. The question asks which property of nutrients shows that they are a type of matter. The correct answer to this question is D. Nutrients have mass.
So, based on the correct answers to these questions:
Q1: The correct answer is B.
