The statements that are true of heterogeneous mixtures are: they settle out and the proportions of solute to solvent may vary. The correct answer is option A. 1 and 2. Heterogeneous mixtures are considered mixtures wherein the components are not uniform and still retain their properties. Characteristics of heterogeneous mixtures are: the ratio of solute and solvent is not equal, the substances can be separated physically and they still retain their properties even if mixed with another substance.
Answer;
C6H12O6 (Glucose)
Glucose is not among the products of cellular respiration. It is actually a substrate of cellular respiration.
Explanation;
Cellular respiration is the process by which plants and animals use to generate energy in the form of ATP which is used to drive cellular activities such as growth and movement.
The process takes place in the mitochondria, nutrients such as glucose are used in presence of oxygen (aerobic respiration) to generate energy in the form of ATP , the process also yields water and carbon dioxide as by products.
Hey there!
I'm assuming it's pointing to the wall in between the two sections of the heart.
We can go over the function of the blue section and red section of the heart. Though I must admit I am not well versed with hearts of birds, I will assume this is similar to a human one. The blue section <u>receives blood from the body which doesn't have any oxygen left in it,</u> and the red section <u>receives blood from the lungs, newly oxygenated.</u> This sector in between separates these two sections, and separates oxygen-poor blood and oxygen-rich blood.
Thus, your answer is option D.
Hope this helps, feel free to let me know if you have any additional questions about this specific problem!
