Answer: Cows that have a spotted coat have a roan coloring. Both genes are expressed. This pattern of inheritance is a result of codominance
Explanation: Every trait is controlled by a gene that occurs in pair. An allele is a different form of a particular gene. Alleles can be dominant or recessive. A dominant gene is one that is able to express itself in the presence of a recessive gene or is able to mask the effect of the other gene. A recessive gene is one whose effect is masked by a dominant gene. When two genes equally express themselves outwardly, they are said to be codominant.
Codominance is a situation whereby neither of the genes is completely dominant rather both express themselves equally phenotypically. In codominance, one gene is not capable of masking the effect of the other.
Carbon Dioxide or CO2 is the waste product of the Krebs Cycle

3. I think the 3rd one?
Explanation:
Hormone production and release are primarily controlled by negative feedback. In negative feedback systems, a stimulus causes the release of a substance whose effects then inhibit further release. In this way, the concentration of hormones in blood is maintained within a narrow range.
