Cleaving a flatworm into pieces would not kill the flatworm as each piece would turn into a new flatworm. The mechanism is known as fragmentation. In multicellular species, fragmentation refers to a kind of asexual reproduction in which a species gets cleaved into fragments.
Each of these fragments forms into completely developed, mature individuals, which are similar to their parents. Fragmentation is also called splitting, it is a mode of reproduction witnessed in various species like molds, filamentous cyanobacteria, lichens, various plants, and animals like flatworms, sponges, sea stars, and some annelids.
Answer
The correct order to describe the carbon cycle would be;
• The carrot plant takes in carbon dioxide from the air during photosynthesis(3)
• The rabbit eats the carrot plant(2)
• The rabbit decomposes(1)
• The carbon compounds are returned to the soil (4)
Explanation
Carbon is captured in the food web through autotrophs (carrot plant) which undergo the process of photosynthesis. The captured carbon will utilized in making organic compounds (glucose). Heterotrophs (the rabbit) will feed on the carrot to allow the organic carbon to proceed into the food chain. Decomposers (acting on dead rabbit) release organic compounds and carbon iv oxide during breaking down of the decomposing matter. Biologically carbon is returned to the environment and soil after this stage.
A learned behavior is a behavior towards responding to a stimulus.In this case, the characteristic of a mink which is leaned will be to release a smelly fluid from a scent gland when threatened.In addition,a learned behaviour occurs when an individual acquires changes in their behaviour which is obtained from their daily interaction with the environment.
A recombinant DNA is artificially constructed DNA molecule with genes of interest that would not be present in the genome otherwise. It is a combination of a vector and a gene of interest. The recombinant DNA is inserted into bacteria E. coli, which, thanks to their reproductive potential, produce multiple copies of this recombinant DNA along with the chromosomal DNA. So, the gene for insulin is inserted int bacteria where is transcribed together with bacterial genes and the great amount of insulin is produced.
