A chromosome is a packaged and organized structure containing most of the DNA of a living organism. Messenger RNA is a large family of RNA molecules that convey genetic information from DNA to the ribosome, where they specify the amino acid sequence of the protein products of gene expression. Proteins are large biomolecules, or macromolecules, consisting of one or more long chains of amino acid residues.
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.
large leaves because the larger the leaves are the easier it is for the plant to take in sunlight. plants need sunlight to perform photosynthesis. photosynthesis is when a plant takes in sunlight and turns it into food for itself. plants are considered autotrophs because they can make their own food. hope I helped!:)
All animals (human, cats, bugs, etc.), plants, fungi, and protists contain eukaryotic cells (meaning cells have a true membrane bound nucleus containing the genetic material) while bacteria are classified as prokaryotes, meaning bacterial cells' genetic material is not membrane bound and just freely floating in the cytoplasm and is called the nucleoid.
