The most important factor that is involved with good health
are those associated with life style because this will affect the person’s life
in terms of his or her health and how he or she will live his or her life,
shape it in order to make him or her live long and happy.
No a small load would take less time because the clothes are more spaced out
Answer;
Cells, bacteria, viruses, DNA
Explanation;
-A scanning electron microscope (SEM) scans a focused electron beam over a surface to create an image. It useful for studying details of a specimen's surface.
-An electron beam passes over the specimen's surface and displaces electrons, which are then focused on a screen to form an image. Uses a conductive material (gold metal) on the specimen.
-The scanning electron microscope gives much higher clarity of a specimen being viewed than the light microscope can; therefore, internal structures of cells, such as organelles, DNA can be viewed in much more detail. Bacteria and viruses can also be viewed in details and studied under a scanning electron microscope.
SUMMATION is the process by which excitatory and inhibitory impulses are combined to determine whether or not a neuron fires.
In physiology, summation is the additive effect of numerous electrical impulses on a neuromuscular junction which is the junction between the nerve cell and muscle cell. The stimuli cannot evoke a response individually. But, collectively they can generate a response.
The summation of postsynaptic potentials, which are excitatory postsynaptic potentials (ESPs) and inhibitory postsynaptic potentials (IPSPs) by a postsynaptic neuron allows a neuron to integrate the electrical information received that is provided by all the inhibitory and excitatory synapses acting on it at any given moment. Whether the totality of active synaptic inputs results in the production of an action potential, this entirely depends on the balance between inhibition and excitation.
Summation has two types: temporal summation and spatial summation. The former is the successive stimulation on one nerve. The latter, on the other hand, is the addition of simultaneous stimuli from conducting fibers.
Therefore, the answer is B. SUMMATION.
