HELP?? 5. What do the results of the agar blocks indicate about the relationship between cell size and diffusion rate?

6. What do the results of the agar blocks indicate about the relationship between cell size and time for materials to reach the center of the cell?

7. How does being small help cells survive?

8. Include an explanation of how the surface-area-to-volume ratio, diffusion rate, and time for substances to reach the center are related. Support your explanation with data.

9. How does being made of many cells help large organisms maintain homeostasis?

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.

cellular respiration oxidizes food into energy in the form of atps.

glycolysis (6 c hexose) > 2x atps are used > 6c hexose biphosphate > 2 x 3c triphosphate >

2 x 3c pyruvate (2x nadh produced from nad) and (4x atp produced)

pyruvate actively pumped mitochondrial matrix.
