Answer:
Perhaps the most fundamental property of all living things is the ability to reproduce. All organisms inherit the genetic information specifying their structure and function from their parents. Likewise, all cells arise from preexisting cells, so the genetic material must be replicated and passed from parent to progeny cell at each cell division. How genetic information is replicated and transmitted from cell to cell and organism to organism thus represents a question that is central to all of biology. Consequently, elucidation of the mechanisms of genetic transmission and identification of the genetic material as DNA were discoveries that formed the foundation of our current understanding of biology at the molecular level.
DNA is made of chemical building blocks called nucleotides. These building blocks are made of three parts: a phosphate group, a sugar group and one of four types of nitrogen bases. To form a strand of DNA, nucleotides are linked into chains, with the phosphate and sugar groups alternating.
Answer: The member of two different species possess similar looking structure that in a similar way perform same function is homology.
Explanation: The term homology describes shared ancestry pair of structures. For example, apes and dogs are different and the arms of ape and forelegs of a dog are derived from ancestry tetrapod structure that perform similar function like aiding locomotion.
Biotic factors are the living components of an ecosystem. They are sorted into three groups: producers or autotrophs, consumers or heterotrophs, and decomposers or detritivores.
The orange beetles are at an advantage because the predator is choosing the green beetles over the orange. The green beetle population may decrease, leaving mainly the orange beetles to reproduce and cause a greater orange colored beetle population over time.
