Answer:
The carbon cycle is nature's way of reusing carbon atoms, which travel from the atmosphere into organisms in the Earth and then back into the atmosphere over and over again. Most carbon is stored in rocks and sediments, while the rest is stored in the ocean, atmosphere, and living organisms.
Answer:
For a contraction to occur there must first be a stimulation of the muscle in the form of an impulse (action potential) from a motor neuron (nerve that connects to muscle). Note that one motor neuron does not stimulate the entire muscle but only a number of muscle fibres within a muscle.
Explanation:
Answer:
The answer is double helix.
Explanation:
In its natural state, each DNA molecule is actually composed of two single strands held together along their length with hydrogen bonds between the bases. Watson and Crick proposed that the DNA is made up of two strands that are twisted around each other to form a right-handed helix, called a double helix.

Motor coretex is essential for receiving information that you are moving your legs.
<h3>What is motor cortex?</h3>
- The motor cortex's main job is to provide signals that control how the body moves. It is anterior to the central sulcus and a portion of the frontal lobe.
- The primary motor cortex, premotor cortex, and supplementary motor area make up this region.
- The motor cortex generates signals that are particular to movements and sends them to the muscles via spinal cord circuits and motoneurons to regulate motor behavior.
- For the execution of movements to be precise, coordinated muscle activation patterns are required.

The answer is; Dead Zone
These areas have anoxic condition means they have very little to zero dissolved oxygen hence cannot support marine/aquatic life. This is as a result of eutrophication caused by algae blooms. This phenomenon is brought about by pollution of these water reservoirs. These algae bloom take up all the oxygen in the water during their mass decomposgion hence leave no dissolved oxygen for the rest of the marine life.
