Crossed-extensor reflex prevents you from falling when you suddenly lift one foot off the ground in response to pain.
- A withdrawal reflex is the crossed extensor reflex. In the withdrawing limb, the extensors relax while the flexors contract, but in the other limb, the opposite happens.
- This can be seen, for instance, when someone steps on a nail; the affected leg pulls away, while the other leg bears the weight of the entire body.
- Contralateral means that the crossed extensor reflex takes place on the side of the body that is opposite from the stimulus.
- Afferent nerve fiber branches travel from the stimulated side of the body to the opposite side of the spinal cord to cause this response.
- They make connections with interneurons there, which then stimulate or inhibit alpha motor neurons to he muscles of the contralateral limb.

Answer:
Partially correct
Explanation:
The statement is partially correct not all the materials needed for growth comes from the soil. For example carbon dioxide comes from air. The experiment that can be use is to get a pot of soil and weigh before planting on it, weigh it again after the plant has grown to a certain stage; The plant will weigh more than the difference in the weight of soil demonstrating that all the materials did not come from the soil.

Phosphorus cycles between living things and the SOIL
Explanation:
Phosphorus flows in a cycle within rocks, water, soil and sediments, and organisms. The phosphorus cycle is the biogeochemical cycle that represents the action of phosphorus within the lithosphere, hydrosphere, and biosphere. Phosphorus is an essential element for all sorts of life. As phosphate (PO4), it delivers up an essential part of the structural core that holds DNA and RNA mutually.
