    1. Since on the earth, the ggg in the equation is equal to one, weight and mass are considered equal on earth. It is important to note that although ggg is equal to one in basic equations, it actually differs throughout earth by a small fraction depending on location; gravity at the equator is less than at the poles.

      g is not equal to one.

    1. a carbon atom has a total of six electrons it's Lewis symbol has four unpaired electrons

      How does a carbon atom have four unpaired electrons if it only has two of them?

    1. RNA stability is controlled by RNA-binding proteins (RPBs) and microRNAs (miRNAs). These RPBs and miRNAs bind to the 5' UTR or the 3' UTR of the RNA to increase or decrease RNA stability.

      RBP, not RPB

    1. Figure 14.2.114.2.1\PageIndex{1}: Each nucleotide is made up of a sugar, a phosphate group, and a nitrogenous base. The sugar is deoxyribose in DNA and ribose in RNA

      Why are you presenting ATP/ADP/AMP here instead of DNA/RNA on the left?

    1. If the round pea parent is heterozygous, there is a one-eighth probability that a random sample of three progeny peas will all be round.

      Please clarify how you calculated 1:8 ratio. One plant has rr and the other plant has Rr. You create a table and get two Rr and two rr which makes the probability of getting three Rr or RR zero.

    1. the cytoplasm in plants is always slightly hypertonic to the cellular environment, and water will always enter a cell if water is available.

      Did you mean hypotonic? Because water enters the cell in a hypotonic situation, not in the hypertonic situation as described before.

    1. Therefore, as a cell increases in size, its surface area-to-volume ratio decreases.

      This is an incorrect statement considering the two given formulas for the sphere and that the cell is in the form of a sphere. The surface are to volume ratio stays constantly three.

    2. its volume increases as the cube of its radius (much more rapidly)

      This is an incorrect statement. Using the given formula for the sphere volume, the volume doesn't increase as the cube of its radius but also by the magnitude of power of two.
