Nerve Regulators: Two types of nerves help to control the action of the digestive system. Extrinsic (outside) nerves come to the digestive organs from the unconscious part of the brain or from the spinal cord. They release a chemical called acetylcholine and another called adrenaline
The correct answer is C. Sphagnum moss
Explanation:
In biology, a renewable source of energy refers to a type of source that replenishes and therefore can be widely used to obtain energy such as wind energy or solar energy that are almost always available. On the other hand, a seedless plant is a type of plant that does not have seed and because of this, they reproduce through sperms.
All fo the plants listed (club moss, horsetail, fern and sphagnum moss) belong to the category of seedless plants; however, from this, the only one that has been widely used a source of energy is sphagnum moss because dried sphagnum moss or peat moss is used as carbon or coals source and therefore is useful for heating building and because it is a plant that grows extensively it is also a renewable source.
Answer:
"Plate movement is thought to be driven by a combination of the motion of the seafloor away from the spreading ridge (due to variations in topography and density of the crust, which result in differences in gravitational forces) and drag, with downward suction, at the subduction zones."

Does this help?
Answer: radio telescopes can be used.
Explanation:
Radio telescopes can be used to see through the dust and the star being born. The stars are born into clouds of gases in the space. Due to gravity more and more gas get collected and it forms a clump. When the clump get big enough the hydrogen atom crash each other to form the helium. The clump of gas becomes a star. The radio telescopes can be used to take pictures of these stars within the clump of gas. It can also be used to take picture of fusion of gases within a star to initiate the formation of new star.
Answer:
True. Carbohydrates readily provide energy anaerobically.
Explanation:
Carbohydrates, proteins and fats all combined provide energy to the body. But whenever our bodies need energy, out of the three carbohydrates are first used to provide it.
Carbohydrates include starch, sugar etc are readily broken down into glucose to fulfil the bodies energy requirements. Blood sugar is one of the most significant energy sources for the body to provide energy to the body at rest or while working. It’s also serves as an energy supply to the brain.
Digestion begins from the mouth. Our bodies release certain enzymes to breakdown food. Then each of our body cells comes in and uses the finished product aerobically or anaerobically into Adenosine triphosphate depending on the need. ATPs are rich in energy and provide fuel to the cells to perform functions.
