The correct answer is as follows.
This is because my parents were heterozygous for the color of the beans. The color of the plant beans is the case of simple Mendelian laws, as there are only two choices for the color of the beans.
What is the meaning of Mendel's laws?Mendel's laws refer to a specific pattern of how a trait is passed from parent to offspring. These common patterns were established by the Austrian monk Gregor Mendel, who conducted thousands of experiments on bean plants in the 19th century.
What is an example of a heterozygous?If the two versions are different, the genotype of the gene is heterozygous. For example, a heterozygous hair color means that there is one red hair allele and one brown hair allele. The relationship between the two alleles affects which trait is expressed.

When you become too cold, your hypothalamus will signal what parts of your body to raise the temperature?
A. Kidneys and lungs
The hypothalamus notices a decrease in body temperature, it sends signals to muscles and skin.
How does the hypothalamus work?Human performance is best when their body temperature is 37 ° C or 98.6° F. The equilibrium of temperature (Homeostasis) is disrupted whenever body temperature rises or increases.Together, the body's organ systems try to sustain homeostasis instinctively and cognitively. They adapt naturally to fluctuations in their external surroundings in order to keep the internal atmosphere at the best possible conditions for wellness.The brain region known as the hypothalamus is responsible for preserving the body's internal equilibrium. It is the area of the brain that keeps track of processes including body temperature, appetite, and the release of different hormones.The hypothalamus is the first organ to notice a decline in body temperature so that homeostasis can be maintained. The message is sent to the muscles and skin, which causes one to tense up and shiver as the blood vessels under the skin tighten.Therefore, it is concluded that when we feel too cold muscles and skin work to raise the temperature directed by the hypothalamus.
