It is absolutely true that infections with legionella pneumophila are usually transmitted via aerosols from contaminated air conditioning systems, showers, and humidifiers.
What are infectious organisms?These are organisms which causes diseases to plants and animals.
Infectious organisms are also called pathogens or pathogenic organisms
Some groups of infectious organisms are as follows:
Bacteria: A single celled organisms with cell walls but no nucleus or organelles.Fungi: An eukaryotic organism typically having chitin cell walls but no chlorophyll or plastids. Fungi may be unicellular or multicellular.Virus: A submicroscopic, non-cellular structure consisting of a core of DNA or RNA surrounded by a protein coat, that requires a living host cell to replicate, and often causes disease in the host organism.So therefore, it is absolutely true that infections with legionella pneumophila are usually transmitted via aerosols from contaminated air conditioning systems, showers, and humidifiers.

Answer:
Explanation:
sedimentary rock
you can see layers in the rock
By looking at the given image, one can see that this can be sedimentary rock.
What is sedimentary rock?Sedimentary rocks are formed by the accumulation or deposition of mineral or organic particles at the Earth's surface, followed by cementation.
Sedimentation refers to the processes that cause these particles to settle in place.
Sedimentary rocks form from previously existing rocks or fragments of once-living organisms. They form as a result of deposits accumulating on the Earth's surface. Layering or bedding in sedimentary rocks is common.
Sedimentary rocks arises from pre-existing rock deposits or even fragments of once-living life form that accumulate on the Earth's surface.
When sediment is deeply buried, it becomes compacted and cemented, resulting in sedimentary rock.

The entire number of genes that an organism receives from its parents makes up its genotype. Alleles, which are pairs of these genes, are found. One gene is dominant and one gene is recessive in each allele.The dominant gene is always expressed in a cross if it is present. Only when a pair of alleles is made up of two recessive genes does the recessive gene express itself.

What is separation and isolation of DNA fragments?
The cutting of DNA by restriction endonucleases results in the fragments of DNA. These fragments can be separated by a technique known as gel electrophoresis.Since, DNA fragments are negatively charged molecules they can be separated by forcing them to move towards the anode under an electric field through a medium/matrix.The most commonly used matrix is agarose which is a natural polymer extracted from sea weeds.The DNA fragments separate (resolve) according to their size through sieving effect provided by the agarose gel. Hence, the smaller the fragment size, the farther it moves.The separated DNA fragments can be visualised only after staining the DNA with a compound known as ethidium bromide followed by exposure to UV radiation (you cannot see pure DNA fragments in the visible light and without staining). We can see bright orange coloured bands of DNA in a ethidium bromide stained gel exposed to UV light.The separated bands of DNA are cut out from the agarose gel and extracted from the gel piece. This step is known as elution.The DNA fragments purified in this way are used in constructing recombinant DNA by joining them with cloning vectors.To learn more about DNA isolation process: brainly.com/question/18316109

You collect individuals from different allopatric populations of a leaf-eating beetle. In the laboratory, you conduct mate-choice experiments to assess levels of reproductive isolation among beetles from different populations. Assuming that ecological speciation occurred in the wild, which pattern should you expect?.
Less reproductive isolation among populations that share similar habitats
What is Reproductive Isolation?The reproductive isolation mechanisms are a set of evolutionary mechanisms, behavioral, and physiological processes that are essential for speciation.
They either prohibit individuals of other species from having children or guarantee that any children are infertile. When individuals or groups diverge in the time of various behaviors, such as foraging or mating, reproductive isolation can arise.
Toad species Bufo americanus and Bufo fowleri exhibit reproductive isolation due to changes in mating season. Members of these species can successfully cross in the lab, resulting in healthy, viable hybrids.

Complete oxidation of one molecule of glucose results in the production of the equivalent of 38 molecules of ATP. This results in the production of 38 molecules of water, because formation of the phosphodiester bond between ADP and inorganic phosphate involves the splitting off of a molecule of water.
