Minerals are also needed for the body although this should be taken in a very controlled amounts only.
Minerals and vitamins combined form the micro-nutrients of the body.
With micronutrients, only relatively little amount of nutrients is required to improve health. They are usually in milligram and microgram amounts and are enough to sustain to the metabolism and growth supplication. On the other hand, macronutrients are those that need large portions and quantities such as carbohydrates, fats and proteins. We need more of these to be converted to energy for movement and muscle growth. </span>
Answer:
C
Explanation:
Single-celled organisms use cell division as their method of reproduction
Answer:
This question is incomplete as it lacks the model, however, it can be answered based on general understanding of photosynthetic process. The answer is;
d. Light is the energy source for converting ADP to ATP, and NADP+ to NADPH.
Explanation:
Light dependent reaction, which is the first stage of photosynthesis, occurs specifically in the THYLAKOID of the CHLOROPLAST where the photons of light is absorbed by chlorophyll molecules (photosynthetic pigment). The light energy that hits the chlorophyll makes it excited, hence, providing the energy to produce ATP from ADP and NADPH from NADP+.
These products are pivotal in the next stage of photosynthesis (light independent stage). Hence, light plays a very crucial role in photosynthesis and the most useful way for communicating the role is by saying it provides the energy source for converting ADP to ATP, and NADP+ to NADPH.
Answer:
31 pairs
Explanation:
Peripheral nervous system composed of neurons outside the brain and spinal cord while the central nervous system is composed of brain and spinal cord. The peripheral nervous system connects the CNS o other parts of the body. The peripheral nervous system may be either autonomic that control the unconscious activities or somatic that control the conscious activities.
Spinal nerves carry the information between spinal cord and body. These neurons are involved in somatosensory information. The divisions of 31 spinal nerves in human body is;
- cervical nerves; 8
- Thoracic nerves; 12
- Lumbar nerves; 5
- Sacral nerves; 5
- Coccygeal nerves; 1
The dorsal and ventral roots connects the spinal nerves to spinal cord and these nerves are formed from combination of nerve fibres. There is an opening between adjacent vertebrae from which spinal nerves originate except the one pair which originate from occipital and atlas bone.
