Bodybuilders are a status group in that they have developed a lifestyle around maximizing the size and appearance of muscles.

A status group is a group of people who are classified into groups based on a system of hierarchy, the basis of which are social factors. These groups are founded by the people inhabiting a society. Body-building is an activity that includes a lifestyle that is based on increasing the size of muscles. This activity requires extreme hard work and daily dedication towards performing extensive exercises and lifting weights. The people involved in this activity have the same end goal of increasing their muscle size. Thus society has grouped people with similar interests and hobbies into different status groups, one of which is body-building.

BSL-2 is appropriate for research with microbes or infectious agents that pose moderate risk to laboratory workers and the community, and are typically indigenous.

BSL-2 biosafety category applies to labs that work with pathogenic or infectious organisms that pose a moderate risk to human health and are connected with human diseases.

Mycobacterium, Streptococcus pneumonia, and Salmonella choleraesuis are BSL-2 organisms. The biological agents in the BSL-3 risk group typically cause major sickness (in humans, animals, or plants) or have the potential to have serious economic repercussions.

Due of the possible risk posed by the aforementioned bacteria, BSL-2 facilities incorporate increased procedures in addition to the usual microbiological practices used in BSL-1 laboratories. Employees in BSL-2 labs are encouraged to exercise considerably more caution to avoid exposure to mucous membranes and injuries like cuts and other skin breaches.

Answer:

Genetic variation in a group of organisms enables some organisms to survive better than others in the environment in which they live. Organisms of even a small population can differ strikingly in terms of how well suited they are for life in a certain environment.

Explanation:

Genetic variations are important because a diverse gene pool is good for long-term survival of a species since the environment is always changing, so the diversity of DNA offers the most fit of the species a better chance of surviving because they are most adapted to the constantly changing environment.

After the bonds are broken between the two strands, each of the strands acts as a template for the construction of a new daughter strand.

The mechanism of replication of DNA is semi-conservative in nature. The double helical strands are  opened using enzymes like helicase. This unwinding occurs at points known as origins. After the helical structure is unwound both strands act as templates for the synthesis of new DNA strands. These new strands are synthesized by the addition of new nucleotides that are complementary to the parent strand. The procedure of DNA replication is considered semi-conservative because the original or parent strands act as templates for the creation of new strands, and a part of these template strands are conserved in the new strand.

Decomposers are important because they develop the mineral salts and other substances that form living beings in the soil or water. These substances can be reused by other living beings.

temperature, humidity and nutrient disposition

Decomposers feed on the remains of living beings, such as plants and animals, and release mineral salts and other nutrients into nature. These nutrients are then used by producing organisms, such as plants, and are therefore reused.

With this information, we can conclude that Decomposers play a critical role in the flow of energy through an ecosystem. They break apart dead organisms into simpler inorganic materials.

Frogs from other subpopulations will occasionally move across fields to recolonize ponds where subpopulations have gone extinct. This is an example of metapopulation.

A group of geographically distinct populations of the same species that interact on some level constitute a metapopulation. Richard Levins first used the word "metapopulation" in 1969 to describe a population dynamics model for insect pests in agricultural fields, but the concept has since been widely used to describe animals that live in naturally or artificially fragmented environments. In Levins' own words, it consists of "a population of populations".

Each metapopulation for a given species is constantly changing due to population growth (births and immigrations), population decline (deaths and emigrations), as well as the development and dissolution of local populations included within it.

ExplanationNervous system:

While the nervous system coordinates and sends signals to every organ, the nucleus controls how each individual cell functions. A nucleus is comparable to the nervous system in this way.

The nucleus controls the activities of the cell by regulating gene expression and upholding the integrity of sequences, making it the cell's control center.

A network of fibrous intermediate filaments surrounds the nucleus, which is also encased in an extremely double membrane known as the "nuclear envelope" and contains almost all the cell's polymer.

The nervous system is an extremely sophisticated part of an animal that uses signals sent to and from various parts of its body to coordinate its movements and sensory data.

The true statements that are true about natural selection are: I, II and III.

Explanation:

Natural selection is one of the main mechanisms of evolution. In a very simple way, it is possible to say that natural selection is a process in which the fittest organisms are selected, survive in the environment, reproduce and pass their characteristics on to their descendants.

With that being said, number I is true because as birds prefer non-hairy caterppillars the hairy ones will be eaten and will gradually disapear. Number II is true because the hairy ones will survive their enviroment, so they are adapted. And number III is true because as hairy caterpillars will survive more than non-hairy, they will be able to reproduce and pass their hairy trace.
