Answer:
Chlorophyll absorbs the light needed for photosynthesis.
Explanation:
Photosynthesis is the process where green plants manufacture their food. During photosynthesis, carbon dioxide combines with water in the presence of light energy from the sun to produce glucose and oxygen as a byproduct.
From the statements listed, chlorophyll does not combine with water. Chlorophyll is a pigment in plant that simply absorbs light energy from the sun which is necessary for the process of photosynthesis. This makes photosynthesis a simple process in which light energy from the sun is transformed to chemical energy.
Answer:
The correct answer is D. Umbilical cord
Explanation:
The umbilical cord connects the fetus to the placenta and through it exchanges nutritional substances as well as oxygen-rich blood. The umbilical cord is maintained throughout gestation until the moment of birth, when it is cut and leaves a permanent scar, the navel. The umbilical cord is responsible for breathing and feeding the fetus until the moment it is born, so any failure or blockage in the circulation of oxygen and nutrients through the cord can lead to injury or even death of the embryo. It also serves to remove waste and carbon dioxide (CO2).
