What are viruses considered to be non-living?
Answer:
Viruses are often considered non-living because outside of a living cell, they do not exhibit the characteristics of living organisms: they are basically like crystals. But within a living organism, they become activated and are able to carry out life's activities like replication (a form of reproduction).
Answer:
Viruses are not made up out of cells they cant keep them selves in a stable state they dont grow and they dont make there own energy. So they are considered non-living.
Explanation:
Cells are living things in the body a virus is what the cells are trying to defeat and because there are no cells in viruses the cells in our body is what fights off the virus cause they are alive and processing in our body.
What is the difference between science and trickery?
Science is- by definition understanding the natural and social world following a systematic methodology based on evidence. Proof is needed, experiments take place etc. Whereas trickery is simply the act of deception, can be for multiple reasons.
However trickery exists in the natural world too in the form of animals using tricks to make themselves look frightening or like another animal. In both cases you cannot believe what you see. The difference would probably be that the tricks science plays can be uncovered by experiments and other observations, but im not sure.
Your question has been heard loud and clear.
Science is basically the logic that explains why things happen and how they occur the way they are , especially with natural phenomena. It is solely used for beneficial purposes so that humans can advance and develop themselves through science.
Trickery is the art mastered by people who just live by using shortcuts and making loopholes out of everything to bypass consequences. It is indeed the complete opposite of science because trickery is not used for improvement like science , but it is used to bring others down while the trickster rises. It is not beneficial for development and advancements. Trickery is however useful to the person using it , and science is useful to the person using it and to the people , but trickery is only beneficial for the person using it , unlike science.

What is the function of nerve cell ?Nerve cells or neurons are the specialized cell for communication which is under the nervous system.
It is composed of cell body with nucleus, axon and dendrites.
Axon and dendrites are the long extension from cell body where as dendrites receive signal and conduct the signal to the cell body.
It involve in transmitting the information throughout the human body, by generating electrical signals called action potentials.
The nerve cell also helps the body in the smooth conduction of metabolic activities.
It involve in both the voluntary and involuntary movement of the body parts.
The communication between the central nervous system is established by the help of nerve cell and the body parts by enabling the smooth transmission of messages.

Explanation:
Hello there! :D
Firstly, I want to say that some of the written out answers look incomplete. I am going to try my best to answer this question and give you context so that you can choose the best answer choice! :)
There are two main systems within the boundaries our nervous system:
The CNS (central nervous system) and the PNS (peripheral nervous system).
Struturally,
the CNS constistues the brain and spinal chord,
the PNS consistutes your nerves and ganglion.
Functionally, the CNS recieves messages from the PNS and sends messages to the PNS. Think of the CNS as the control center, and the PNS as the reactor.
The PNS has two systems within it, the somatic nervous system, and the autonomic nervous system. The somatic nervous system senses things consciously percieved (ie. eye sight, pain, taste) and the autonomic nervous system senses things unconsciously percieved and controled (ie. stress, anxiety, etc). The point being, you cannot control when it happens or stop the function of it consciously.
The autonomic nervous system holds two main systems, which would be the parasympathetic system and the sympathetic system. The parasympathetic system helps maintain your circadian rythmn, replenish energy, and relax your body. The sympathetic system is known as your "fight or flight" system. This system can be triggered by test anxiety, unsafe situations, and in any case where your life or emotional well being is being threatened.
My best answer for this question, in my opinion, would be the autonomic nervous system, and the sympathetic system. The sympathetic system deals with fear (fight or flight) and is controlled by the autonomic nervous system).
I hope this helps you and you have a wonderful day,

a. deductive reasoning
b. inductive reasoning
c. reductive reasoning
d. productive reasoning
Answer: Option B
Inductive reasoning.
Explanation:
It is inductive reasoning because inductive reasoning is a type of reasoning in which general informations are made based on some specific observations or information even when the conclusion is not complete guaranteed to be true.
This means that you make a guess's or generalizations based on the information you have at hand.

Monosaccharides are the monomers and polysaccharides are the polymers of carbohydrates. Amino acids are monomers and polypeptides are the polymers of proteins. Nucleotides are the monomers of nucleic acid and polynucleotides are the polymers of nucleic acids. Fatty acids and glycerol are monomers and triglycerides are the polymers of lipids.
What are monomers and polymers?Lipids, Polysaccharides, Proteins and Polynucleotides are the four major groups of macromolecules that are found in the bodies of all living organisms. These are also called biomolecules.
Monomers are small molecules which are generally organic. These molecules combine with other similar monomers which form large molecules. These are polymers. All the monomers can form chemical bonds with at least two monomer molecules.
A class of synthetic substances that are composed of multiples of simpler units or monomers are called polymers. These are the chains of monomers which have a nonspecified number of monomeric units.
Therefore, monosaccharides are the monomers and polysaccharides are the polymers of carbohydrates. Amino acids are monomers and polypeptides are the polymers of proteins. Nucleotides are the monomers of nucleic acid and polynucleotides are the polymers of nucleic acids. Fatty acids and glycerol are monomers and triglycerides are the polymers of lipids.

Computer modeling gives scientists the ability to study the interaction of complicated systems
without actually conducting an experiment. Is this
True or false.?
Answer:
it is true
Explanation:
Computer modelling can be defined as the computerization of mathematical models in order to understand the dynamics of biological, physical, and chemical systems. The computerized simulations can be run by using programs that have into account the parameters of the system and thus make predictions that resemble natural experimentation procedures. Examples of computer modelling include, among others, the potential distribution of invasive species, prediction of changes in the genetic structure of a given population over n generations, etc.

Some mammals help maintain their body temperature by sweating when their bodies rise in temperature. Which property of water is responsible for the ability of sweat, which is mostly water, to help lower body temperature? Water absorbs heat by breaking hydrogen bonds. Water changes in density when it changes from a gas to a liquid. Water's ability to dissolve solutes, such as salt Water's ability to form hydrogen bonds with skin cells
Answer:
Water absorbs heat by breaking hydrogen bonds.
Explanation:
Specific heat is the amount of heat that must be absorbed or lost for 1 gram of that substance to change its temperature by 1 degree.
