Answer:
P:coughing; C. saliva: B: complement system
Explanation:
The physical, chemical, and biological immune responses are complement system, saliva, and coughing. Therefore, the correct statement is option A.
What is complement system?The complement system is a physical immune response consisting of a group of proteins working together to kill pathogens that enter the body. Saliva is a chemical immune response, which involves secretions, such as sweat, tears, mucus, etc. containing enzymes that can inhibit the growth of pathogens.
Coughing is biological immune response that activates the immune cells such as macrophages and T cells that can recognize and attack pathogens entering the body.
The complement system involves the production of proteins to destroy foreign bodies. Saliva and coughing are chemical and physical responses to expel pathogens from the body, thereby, providing immunity to the body.
Therefore, complement system is identified as physical immune response, saliva as chemical immune response, and coughing as biological immune response.

.Specific processes must take place within the cell for protein synthesis to occur. The processes that take place within a cell for protein synthesis to occur. Which occurs during translation but not during transcription? A DNA template is used to create an mRNA strand. A tRNA template is used to create a DNA strand. A tRNA template is used to create an mRNA strand. An mRNA template is used to create an amino acid chain.
Answer:
An mRNA template is used to create an amino acid chain.
Explanation:
Transcription is the first step in the protein synthesis process. Translation is the second.
Overall, the central dogma of biology is DNA->RNA->protein.
Transcription is that first step, DNA to RNA, and translation is RNA to protein: think of it like nucleic acids can just be transcribed, but nucleic acid to protein is like a whole different language, so it has to be translated. So the correct answer here is that mRNA is used to make amino acid chain (aka protein), which happens only in translation.

A type of cellular transport is shown. Which description best identifies this type of cellular transport? Your answer: A.Osmosis, because energy is being used to move molecules with the concentration gradient. B.Active transport, because energy is being used to move molecules against the concentration gradient. C.Facilitated diffusion, because energy is being used to move molecules with the concentration gradient.
Answer:
B. Active Transport
Explanation:
The concentration gradient is from high to low. The molecules are moving from low to high which is against the concentration gradient. Also, the ATP symbol is shown pointing, and ATP is energy.
The description that best identifies the type of cellular transport being depicted in the image would be that of active transport because energy is being used to move molecules against a concentration gradient.
There are basically 2 types of cellular transports:
PassiveActivePassive cellular transports are those that do not require energy in any form. They include osmosis, the movement of water molecules from the region of high to low water potential via a semi-permeable membrane, and simple/facilitated diffusion, the movement of molecules from regions of high concentration to regions of low concentration.
Active transports are those movements of materials in and out of the cell that requires the expedition of energy in the form of ATP. It is usually the movement of materials against their concentration gradients. Examples include vesicle transport, ion pumps, etc.
In the illustration, the direction of movement of the molecules (by the arrow) indicates that it is against the concentration gradient. Also, the burning of ATP gives further credence that is an active system of cellular transportation.

Fossil fuel energy is a form of non-renewable form of energy. Thus, the correct option will be A.
What is Non-renewable energy?A non-renewable energy resource is a natural resource which cannot be readily replaced by the natural means at a particular pace which is quick enough to keep up with the consumption of the energy resource. An example of the non-renewable energy resource is a carbon-based fossil fuel. The original organic matter with the aid of heat energy and pressure generally becomes a fuel such as the oil or natural gas.
There are four major types of the nonrenewable resources which include oil, natural gas, coal, and the nuclear energy. Oil, natural gas, and coal are collectively known as the fossil fuels. Fossil fuels were formed within the Earth from the dead plants and animals over a period of millions of years and hence are named as the fossil fuels.

Which option describes cations?
Answer:
D
Explanation:
A cation is a positively charge ion, such as a sodium ion, as when it becomes an ion, it gives away electrons, becoming positively charged.
The opposite is an anion, which is a negatively charged ion, such as oxygen as it receives elections from the cation when forming an ionic bond.
Cations are the positively charged ions.
What are cations?A cation has more protons than electrons, consequently giving it a net positive charge. For a cation to form, one or more electrons must be lost, typically pulled away by atoms with a stronger affinity for them.
The number of electrons lost, and so the charge of the ion, is indicated after the chemical symbol, e.g. silver (Ag) loses one electron to become Ag+, whilst zinc (Zn) loses two electrons to become Zn2+.
In contrast, most nonmetallic atoms have a stronger attraction to electrons than do metallic atoms, and as a result, they gain electrons to form anions.
Therefore, Cations are the positively charged ions.

We know the molecule below is an unsaturated fat because the molecule contains carbon double bonds.
What is an unsaturated fat in molecule?An unsaturated fat is a fat or fatty acid in which there is at least one double bond within the fatty acid chain. A fat molecule made of chains where some carbon atoms are not fully saturated with hydrogen atoms.
Unsaturated fat, a fatty acid in which the hydrocarbon molecules have two carbons that share double or triple bond and are therefore not completely saturated with hydrogen atoms. Due to the decreased saturation with hydrogen bonds, the structures are weaker and are, therefore, typically liquid at room temperature.
Unsaturated fats are either monosaturated fats, as in olive or canola oils, or polyunsaturated fats, as in nuts, seeds, and seed oils
