Neurons are constantly carrying action potentials (meaning electrical signals) in order to result in a certain action carried out by the body. Therefore, Neurons need a high amount of ATP to carry an action potential throughout the nervous system to be processed by the brain and then initiate a motor (physical response)
For example if you touch a hot stove, sensory neurons will take the "hot" information from the hand to the spinal cord which has relay neurons which connect the action potential (which is the information) to the brain. The brain in response will interpret that information and initiate a motor response. Which will result in you taking your hand off the stove. This entire process of responding to stimuli takes a lot of energy to take place. Just the brain itself takes about 20% of all daily basal energy (which is the energy required to keep you alive).
They work to convert light energy of the sun into sugars that can be used by cells
The correct answer is a - silicon dioxide.
Diatoms are single celled algae. They have a silica - based cell wall called a frustule, which gives each diatom a particular shape.
Diatoms exist as separate single cells although some may be found in groups or colonies. The ones found in colonies create very pretty forms: leaf shaped, oval , star and even like a period.
Outer shells of diatoms are quite valuable. They are used in industry in the manufacture of toothpaste to give it grit.
You should consider how much you want to make, so make a budget. See if the equipment is good quality.
Answer:
During the asexual reproduction, bacteria can divide simply by binary fission in which one bacteria first replicate its genetic material and the cell divide in two daughter cells which are identical to the parent cell.
Asexual reproduction does not allow genetic variation therefore to get genetic variation bacteria can use conjugation, transformation and transduction process.
In conjugation, bacteria gets extra genetic material from other bacteria through sex pills. In transduction the genetic material enters into the bacterial cell through the virus then bacteria incorporate this genetic material in its genome.
In transformation, bacteria takes up the extra genetic material from it's surrounding. Therefore conjugation, transduction, and transformation helps bacterial to gain variation like as in sexual reproduction.
