Answer:
LIGHT ENERGY is converted to CHEMICAL ENERGY in the process of PHOTOSYNTHESIS
Explanation:
According to the law of conservation of energy, energy cannot be created nor destroyed but can only be changed from one form to another. This means that no form of energy gets destroyed but only transformed. This is evidently so in so many natural processes including the process of PHOTOSYNTHESIS undergone by plants.
Photosynthesis, which is the way plants obtain their food via sunlight, converts the LIGHT ENERGY of the sun to CHEMICAL ENERGY in glucose produced. Hence, photosynthesis obeys the law of conservation of energy.
Answer:
Repolarization
Explanation:
Repolarization refers to the phase during which the resting potential is restored after depolarization. This means that the inside of the axon membrane becomes negative again compared to the outside.
Repolarization is obtained by the functioning of K+ ion channels. The opening of K+ ion channels allows the K+ to move outside of the axon. Movement of positively charged ion (K+) outside of axon makes the inside negative again and the resting potential is restored.
Answer:
Diatoms
Explanation:
Diatoms are a photosynthetic eukaryotic phytoplankton that virtually found in all waterways, fresh waters and oceans, and also in most soils on earth. Diatoms play a very important role in the global carbon cycle. Diatoms are single-celled algae that has a characteristics cell wall that is made up of transparent opaline silicia that are elegantly sculpted.
When diatoms die, their shell or skeleton that is composed of silica, do not decay, but settle at the bottom of oceans as sediments to form what is often referred to as diatomaceous earth. It is this diatomaceous earth deposit that is then converted to diatomite powder, which is used as pesticides against insects such as ants, cockroaches, bedbugs and some other pests.
Answer:
Neurons in the parasympathetic division release neurotransmitters that act on receptors that slow heart rate
Stimulating the organs of digestion is a parasympathetic response
Parasympathetic nerves are associated with the cranial and sacral regions of the spinal cord, whereas sympathetic nerves are associated with the thoracic and lumbar regions
The sympathetic division of the PNS prepares the body for physical exertion in stressful situations.
Explanation:
The autonomic nervous system also called the vegetative nervous system is part of the peripheral nervous system which inervates smooth muscle and glands. Thus, it directly affects the function of internal organs and regulates functions such as the heart rate, digestion, respiratory rate, urination etc. This nervous system control is unconscious.
The autonomic nervous system is divided into: the sympathetic nervous system, the parasympathetic nervous system and the enteric nervous system.
Parasympathetic nervous system works when organism is at rest so it is known as system responsible for "rest and digest functions". On the other hand, sympathetic nervous system works at active and stressful situations and it is known as "fight and flight" system.
