Bacteria are some of the best examples of prokaryotic organisms. These organisms do not have a membrane-bound nucleus and lack the well-distinguished cell features found in eukaryotes.Know More
Specific examples of prokaryotic organisms include the Escherichia coli bacterium and the Streptococcus bacterium. These are more recognizable as E. coli, a bacteria often found in meat, and the bacteria that causes strep throat.
There is an entire kingdom devoted to prokaryotes, named Archaebacteria. These prokaryotes are ancient forms of bacteria and are notable for living in extreme conditions, such as geothermally active pools and extremely acidic waters. They are considered to be the oldest living organisms on the Earth.Learn more in Biology
The energy used by all living organisms on earth can be traced back to the sun. The sun produces heat and light energy which helps in maintaining temperatures on earth and creates daylight. Plants, which are sometimes referred to as producers, use light energy in a process called photosynthesis to create nutrients or energy.Full Answer >
A biology investigatory project is a project involving a combination of research and scientific experimentation that relates to the study of living organisms. Investigatory projects typically lead to a final presentation at an exhibit or science fair, or a report.Full Answer >
An incomplete dominance Punnett square is a diagram that predicts the outcome of genotype as well as phenotype in organisms. With incomplete dominance, the dominant allele in a heterozygote is only partially expressed, which results in an intermediate phenotype.Full Answer >
A biological key, also known as an identification key or a dichotomous key, is a way to classify organisms by giving the classifier two options in each stage until identification occurs. For example, in order to identify the tree, a biological key gives two choices – conifer or broadleaf – with a description of each one. Depending on the answer, another question pops up to narrow down the species.Full Answer >
