Answer: Option C
Explanation:
A biological species can be defined as the concept which includes the group of individual which lives in one or more population that can reproduce among each other to produce viable species.
Speciation is the phenomenon by which one group of species gets separated from another. The species gets diverge due to reproductive isolation or due to geographical isolation.
Hence, the correct answer is option C
Answer: For building amino acids, proteins and nucleic acids.
Explanation:
Living cells requires nitrogen because they are major part of amino acids. They form the building block of protein and nucleic acids such as DNA which carry the genetic information and is passed from generations to generations. Plants and animal need nitrogen for growth and survival. The protein is use for building and repairing muscles and it is a necessity for growth.
Nitrogen is crucial for all cells as it forms the backbone of amino acids, proteins, and nucleic acids which perform essential roles in cell function.
All cells require nitrogen as an essential component for living organisms as it is an essential part of amino acids, proteins, and nucleic acids. Nitrogen forms the backbone of these molecules, which are fundamental structural and functional elements in cells. Amino acids are the building blocks of proteins, which perform many vital biological functions in cells. Similarly, nucleic acids, namely DNA and RNA, carry genetic information and are crucial in the synthesis of proteins. Without nitrogen, these molecules cannot exist and therefore, nitrogen is fundamental to all living organisms.

Answer:
Please find the definition of viscosity, effect of heat on DNA explanation to this question below
Explanation:
Viscosity is a term used to describe FLUIDS, which includes liquids and gases. Viscosity refers to the ability of a gas or liquid to resist flow. In other words, it is the measure of the internal friction that exists between the molecules of a fluid, which resists its flow.
DNA in its natural state exists in a liquid solution, hence, when HEAT is applied, the heat causes ITS MOLECULES to MOVE RELATIVELY FAST and as a result the molecules lose the friction between them and begin to flow. Based on this, heat is said to make DNA LESS VISCOUS i.e. to flow more rapidly.
Viscosity refers to the 'thickness' or 'stickiness' of a fluid. Heat decreases the viscosity of DNA by providing energy to the molecules, which reduces the 'stickiness' between them. The underlying cause is changes in the interactions between the DNA molecules due to the heat energy overcoming the forces holding them together.
Viscosity is a property of a fluid that resists the force tending to cause the fluid to flow. In simple terms, it is the 'thickness' or 'stickiness' of a fluid. The greater the viscosity, the slower the fluid flows.
When exposed to heat, the viscosity of DNA decreases - it 'thins' and flows more easily. This happens because heat provides energy to the DNA molecules, increasing their movement and reducing the 'stickiness' between them.
The underlying cause of the change in viscosity due to heat is actually due to a change in the interactions between the DNA molecules. The added heat energy overcomes the forces holding the molecules close together, allowing them to move more freely relative to each other, thus decreasing the viscosity.
