Answer:
Gate theory claims that pain sensations must pass through a space, or gate, in the spinal cord, which can be closed to block pain signals sent from the brain or peripheral receptors.
Explanation:
According to the gate control theory, the activities of large fibres cause the excitation of inhibitory neurons. This reduces the transmission of pain signals.
What is gate control theory?
This is a type of defence mechanism by our nervous system. In this mechanism, the signals that are sent to the brain, by the spinal cord for the perception of pain, are managed by the spinal cord itself.
This may include the mechanism of reducing or increasing the pain. Therefore, the gate theory can heighten or decrease the perception of pain meaning the gate can either be closed or it can be open. The pain signals will pass to the brain if the gate is open and they will be restricted to the spinal cord if the gate is closed.
A painful or noxious stimulus of pain can be restricted or managed by a non-noxious stimulus. Like a backache can be managed by a gentle back massage.
Therefore, a gate control mechanism helps in blocking the perception of pain in the spinal cord.

The artichoke is a huge, thistle-like perennial plant of the aster family (Asteraceae), often known as the globe artichoke or the French artichoke, and its flower buds are farmed for their gastronomic qualities.
The young bloom bud of a thistle is an artichoke. It is considered a vegetable in cuisine and is consumed as such. The plant, an aster, is plucked for its buds rather than its flowers. It takes some effort to get to the edible sections of an artichoke, which makes it a difficult vegetable to prepare.
What are some examples of UCS, UCR, and CS?
The chemotherapy medications are the unconditioned stimulus (UCS) in this scenario, the vomiting is the unconditioned response (UCR), and the doctor's office is the conditioned stimulus (CS) after being matched with the UCS and UCR.

Which step in the process of photosynthesis is dependent on light energy?
A.splitting of water into hydrogen and oxygen
B.combining carbon and oxygen into carbon dioxide
C.splitting carbon dioxide into carbon and oxygen
D.combining hydrogen and oxygen to form water
Answer:
D. Combining hydrogen and oxygen to form water.
Explanation:
The process of photosynthesis which is dependent on light energy is the
combining of hydrogen and oxygen to form water.
Photosynthesis involves the reaction between carbondioxide and water to
form Starch and oxygen. The water molecules however have to be split
because of movement of electrons in which the water become oxidized and
carbondioxide reduced.
This process however have to be done in the presence of sunlight which
serves as a precursor.

* C.
The rapid growth of prokaryotic cells generates more viruses.
* D.
Unlike eukaryotic cells, prokaryotic cells do not have a nucleus.
Answer:
DNA in eukaryotic cells lie within the nucleus. This DNA has a membrane protecting it from the outside. This means that the virus would have a harder time getting to the DNA to insert its DNA in a Eukaryotic Cell.

Unlike eukaryotic cells, prokaryotic cells do not have a nucleus.
What are prokaryotic cells and eukaryotic cells?Prokaryotes are organisms whose cells lack a nucleus and other organelles. Eukaryotic cells have a membrane-bound nucleus.
Eukaryotic cells have a separate organelle named nucleus (plural: nuclei) which is a double membranous structure meant for the storage of genetic material i.e. chromosomes (DNA). Prokaryotes on the other hand have an irregularly shaped structure named nucleoid instead of nucleus. All the genetic material of the prokaryotes is within the nucleoid. Unlike nucleus, nucleoid does not have any nuclear membrane & it is spread in the cytosol freely.
Hence, option D is the correct answer.
