<h3><u>Answer;</u></h3>
Carbohydrate
<h3><u>Explanation;</u></h3>
- Carbohydrate is the macromolecule produced during photosynthesis for plant food. Carbohydrate is among the four major macromolecules, others being, nucleic acid, lipids, and proteins.
- During photosynthesis energy from the sun, together with water and carbon dioxide are used to make nutrients or organic compounds such as simple sugars like glucose.
- By using the energy from the sunlight and absorbing the water molecules from the soil, the plant produces glucose molecules. The glucose is a carbohydrate.
The answer are the hands and feet. It is the continuously changes of the
characteristics of the body, most noticeable in height and weight. The ages 13-15 and 17-18 the two major brain
growth spurts occur. In times of growth spurts the changes is visible during the
first year of puberty.
The right option is; it interprets signals from the external environment
The peripheral nervous system (PNS) is made up of all parts of the nervous system, except the brain and spinal cord (parts of the central nervous system). The peripheral nervous system functions as a channel through which neural signals are transferred from and to the central nervous system. Two types of neurons (sensory and motor neurons) functions in the PNS. The motor neurons transfer neural signals from the central nervous system directly to various muscles, glands, and organs (effectors) throughout the body.
