Explanation:
t8ssues makes up organs, organs make up an organ system and that makes an organism
Answer:
Nucleus
Explanation:
In eukaryotic cells, the nucleus is a membrane-bound structure that contains the genetic material, which is expressed in response to cell stimuli (i.e., environmental stimuli). This genetic material consists of genes that are expressed in response to cell signaling events. For example, the transcription factors that are found in the cytoplasm are activated after receiving a signal from receptors localized in the cell membrane, when these membrane receptors bind to specific signaling molecules. Subsequently, these transcription factors are translocated into the nucleus to interact with DNA promoter regions in order to activate the expression (transcription) of target genes capable of responding to an environmental stimulus.
Symaptric speciation is the formation of new species in populations that live in the same geographic area, while allopatric speciation occurs when the population is separated by a geographcial area. So, according to this: The difference between the sympatric speciation and the allopatric speciation is that sympatric speciation involves a behavioral barrier, while allopatric speciation involves a physical barrier.
