Protect. The immune system protects the body from diseases and harmful pathogens. The skeletal system keeps you upright and supports you with help from the muscles.
Answer:
Meiosis
Explanation:
Gene recombination refers to the mixture of genes from different individuals that occurs during sexual reproduction. Gene recombination is responsible for mixing between genes, which results in genetic variation in a bacterial population.
Genetic variability in a bacterial population occurs through three types of mechanisms: transformation, conjugation and transduction. However this genetic variation does not occur through Meiosis.
Transformation is the incorporation of free DNA by the bacterial cell. Conjugation is the process of transferring DNA from one bacterium to another, involving contact between the two cells. Transduction is the transfer of genetic material between cells, mediated by bacteriophages.
Protein
Proteins are the most versatile
macromolecules in living systems and they play important roles in essentially
all biological processes. Protein makes up the capsid of a virus. The infective
extracellular form of a virus known as a virion contains at
least one unique protein synthesized by specific genes in the nucleic acid of
that virus. In almost all viruses, at least one of these proteins forms a shell
(called a capsid) around the nucleic acid. Certain viruses also have other
proteins internal to the capsid. Some of these proteins act as enzymes during
the synthesis of viral nucleic acids.
It is supported by evidence from a wide variety of scientific disciplines, including genetics, which shows that different species have similarities in their DNA. There is also evidence supporting the Theory of Evolution in paleontology and geology.
Answer:
The last one: dinosaur footprints preserved in mud turned to rock
Fossils have to be physical remains of an animal.
