Answer:

Genetic diversity is a good principle for secure development because it is critical for a population to adapt to changing environments. It helps maintain the health of a population.

Explanation:

Genetic Diversity refers to the range of different inherited traits within a species. In a species with high genetic diversity, there would be many individuals with a wide variety of different traits.

Mutations are important to genetic diversity because it creates a new DNA sequence for a particular gene, creating a new allele. This is important because including alleles that are diverse may be valuable in resisting diseases, pests, and other stresses

Genetic diversity is a good principle for secure development because it ensures the chances of adaptation in living organisms with respect to changing environmental conditions.

Genetic diversity may be defined as the total number of genetic characteristics in the genetic makeup of a species. It serves as a way for populations to adapt to changing environments. It facilitates the survival of particular species.

A lack of diversity may have a negative impact on security. This can be understood by the example that if there were not many variables seen in the Darwin finches in the Galapagos islands, more birds feel the scarcity of food and due to this, they have died and become extinct from nature.

Therefore, with more genetic variation, it is more likely that some individuals in a population will possess variations of alleles that are suited for the environment.

Answer:

The energy of a body or a system with respect to the position of the body or the arrangement of the particles of the system.

Explanation:

Energy is a delicate notion that is extremely difficult to master. Energy is sometimes described as the ability to accomplish labor, that is, to push anything against a force. That isn't completely correct, since due to the Second Law of Thermodynamics and the fact that much energy is merely mass, there is a lot of energy that isn't accessible to do any work. We're on somewhat better ground with potential energy. When we say there is potential energy, we mean that there is something in a system that, if permitted to alter, has the capacity to accomplish work. Saying that there is potential energy is a form of abbreviation. Consider gravitational potential energy. If two masses are separated by a distance, we might let them fall together and accomplish some work, perhaps by pulling a rope tied to a wheel or whatever. We have the energy to get there. Of course, it is a fraction of the overall energy in the system. When we get to notions like that, we must count a lot more. Nonetheless, some cosmological models require a type of negative gravitational potential energy to make total energy conservation work. According to such views, nearly all of the universe's mass condensed out of the vacuum to offset the negative energy associated with the inflationary epoch. As a result, the universe's total energy is zero. It is not the sole hypothesis, but it is useful in that it answers the issue of why there is something rather than nothing. It would imply that there is nothing completely, but it is unevenly dispersed. One of the two major forms of energy is potential energy. Potential energy is the amount of energy that an object can hold. It is the power that a thing has while it is not in motion. The potential energy of a moving item increases as it slows down. The object's capacity strength reduces as it accelerates. Potential energy is the electricity that occurs as a result of the relative locations (configurations) of the components in a physical machine. This energy form has the capacity to modify the state of other things around it, such as the configuration or movement. Potential energy encompasses a wide range of energy kinds.

The study of the cell theory required the use of more sophisticated microscopes hence development of the cell theory is directly related to advances in microscope technology.

The cell theory portrays the idea that a cell is the smallest unit of an organism. Cells are so small that they can nit be seen with the ordinary optical eyes. As such, the eyes must be aided by a device such as a microscope to make the study of the cells possible.

From the time of Robert Hooke when the cell theory began to take more shape, the complex microscope was discovered. As time went on, the cell theory was advanced and more sophisticated microscopes had to be produced.
