Answer:
Nucleic Acids Proteins Carbohydrates
Lipids
Explanation:
All organisms need four types of organic molecules: nucleic acids, proteins, carbohydrates and lipids; life cannot exist if any of these molecules are missing.
Answer:
Color of light/Type of light
Explanation:
B/c by definition of independent variables, these are the variables that are manipulated to see how it affects the other value (which is aka dependent variable). Color of light is independent because you have multiple manipulation which can be clearly seen in the different types of lights and the height is dependent on what color of light it is exposed to.
Additionally,
Dependent variable - the height of the plant
An independent variable is not affected during the experiment. It is what experimenter controls. The dependent variable is called dependent because it depends on the independent variables. Here, the height of the plant depends on the color of the light, therefore the height of the plant is dependent variable and the color of the light is the independent variable.
Answer:
This is known as the chemical equilibrium phenomenon.
If one body part is not working properly, it affects others also. The direct influence of any such abnormality can be seen of the homeostasis of the body. If an infection occurs, it leads to release of the signals which also increase the body temperature, and homeostasis is disturbed. Similar is the case of the nervous system. If it is not working properly, hormones related to maintenance of homeostasis are affected and ultimately, other body systems including excretory and endocrine are directly affected. If circulatory system is affected, then plasma, which acts as a buffer system is hampered and a direct influence can be seen on heart and kidneys also.
Answer:
Xylem transfers water up from the roots to the leaves.
Phloem transfers sugars (glucose) produced in the leaves down to the roots to be stored.
