What three things might influence a slide when conditions are right? What types of material can make up a flow? (Site 1).
A slide can be influenced by friction, weight, and the angle of the slope. The materials that form flow generate less friction depending on the environmental conditions.
A slide is a movement that occurs when a fragment of soil/rock suddenly moves down a slope.
Slope stability is a factor influenced by the angle of the slope and the strength of the materials (e.g., rocks) on it.
The slide movement can ultimately be considered as a battle between friction versus gravity.

can someone explains (summarize) what photoperiodism is? And if it’s the same as photoperiodism
Answer: photoperiodism means the response of an organism to seasonal changes in day length. Photoperiodism isn't the same as Photoperiod because Photoperiodism merely refers to the potential of the plant to incite flowering relative to the changes in the photoperiod. Thus, photoperiod is a light duration or the length of day and night, while photoperiodism is the effect of light duration on the plant’s growth.

4 ^ 3 because your first nucleotide can be any of the 4, same with your second, and same with the last nucleotide. 4^3 tells you there are 3 different positions that 4 different bases can be placed.
Hope this helps!
There are 64 possible combinations of nucleotides to form a given amino acid.
The genetic code to add an amino acid is the result of a triplet of nucleotides or codons. In consequence, there are 4^3 possible combinations of nucleotides in a codon.This number (64) gives us the number of different codons that can be found in the genetic code.In conclusion, there are 64 possible combinations of nucleotides to form a given amino acid.

Postganglionic sympathetic axons are carried from the sympathetic trunk to all spinal nerves through ______.
Answer:
gray rami communicantes
Explanation:
Postganglionic sympathetic axons are carried from the sympathetic trunk to all spinal nerves through gray rami communicantes. The sympathetic nervous system is almost connected to all parts of the body.
What is the nervous system?The nervous system is made up of neurons that are connected to each other and send the message for action to different parts of the body. The whole nervous system of the body is divided into three parts: the central nervous system, the peripheral nervous system, and the autonomic nervous system.
The central nervous system is composed of the brain and spinal cord, while the autonomic nervous system is composed of the sympathetic and parasympathetic nervous systems. The peripheral nervous system includes the nerves of the brain and spinal cord that are derived from these two organs. The sympathetic nervous system activates the majority of the organs in times of danger, whereas the parasympathetic nervous system is associated with rest.
Hence, Postganglionic sympathetic axons are carried from the sympathetic trunk to all spinal nerves through gray rami communicantes.
