During cellular respiration, organisms convert different kinds of food into glucose. Cells then break down the glucose to provide energy for life activities. Which of these substances is also produced during cellular respiration?
A. Carbon dioxide
B. Fat
C. Oxygen
D. Protein
Fat, of these substances is also produced during cellular respiration. Thus, option (b) is correct.
What is respiration?Respiration is the transmission of oxygen from the outside world to cells within tissue, as well as the elimination of carbon dioxide in the reverse direction. It is a physiological reaction that occurs within living creatures' cells. We can breathe because of our lungs and respiratory system.
Glycerol is converted into one of the intermediates of glycolysis and hence enters the aerobic respiration pathway. Fats are a fuel for cellular respiration. It provides the most energy among lipids, carbs, and proteins. Fat is a triglycerides molecule.
As a result, the fat, of these substances is also produced during cellular respiration. Therefore, option (b) is correct.

What is the main challenge astronomers face when trying to directly detect black holes? (1 point)
Black holes are too black
Black holes are empty.
Black holes trap all light.
Black holes are too small.
Answer:
Black holes trap all light.
Explanation:
This temperature is on the order of billionths of a kelvin for black holes of stellar mass, making it essentially impossible to observe directly. Objects whose gravitational fields are too strong for light to escape were first considered in the 18th century by John Michell and Pierre-Simon Laplace.
Answer:
1. How do emission and reflection nebulae differ?
interactions with light
2. Where could scientists look to observe a black hole?
the center of the Milky Way
3. Which description best summarizes the steps that take place during black hole formation, in the correct order?
A massive star depletes its nuclear fuel; gravity overpowers the star; supernova occurs; core of star collapses.
4. Select the correct answer from the list.
To form a nebula, gravity pulls matter together or causes an explosion.
5. Which of these characteristics of a star make it most likely to become a black hole? Select the two correct answers
It is dying.
Its mass is greater than 20 times the mass of the sun.
6. Which statement best describes the galaxies closest to the Milky Way?
These galaxies include irregular, spiral, and elliptical types.
7. Select the correct answer from the list.
Astronomers think that most galaxies are centered by a black hole which exerts gravitational pull that binds the galaxy together.
