QuestionAnswer
what characteristics do all living things have cells, have DNA, reproduce, have chemicals, and use/need energy.
multicellular organisms have two or more cells, are more complex, specialized to different tasks, and the cells work together. unicellular organisms have one cell, and are more simple.
the difference is that sexual creates an offspring with a combination of DNA from two patents, and asexual creates an identical offspring to one parent.
dissolved and transports substances easily.
provide cells with energy, and are made of sugars (simple or complex).
used for building cells, and provide structure.
provides instructions to carry out the functions of life.
all living things need water, food; space, and homeostasis.
homeostasis means to maintain a stable environment for living, and there are many ways to do this.
stimulus: fire alarm goes off/ response: jump up, adjust to sound. stimulus: light turns on/ response: eyes widen and adjust stimulus: touch something hot/ response: pull back, treat hand and get it back to normal temperature.

domain.
species
domain, kingdom, phylum, and class.
archaea are unicellular organisms, do not have a nuclei, are microscopic, and live in harsh environments.
bacteria are unicellular, do not have a nuclei, are found all around us, and are microscopic.
eukarya have a nuclei and are multicellular.

π˜Ύπ™–π™‘π™«π™–π™©π™žπ™– is the genus.
they are in the eukarya.
can move around, heterotrophs (ex. amoeba, giardia)
mostly autotrophs, some can move around, but some are attached (ex. red algae, dinofagellates)
heterotrophs (ex. slime molds and water molds)
bacteria and viruses are similar because they are both small, both have DNA and protein, and they both reproduce.
bacteria and viruses are different because bacteria are living and viruses are not.
viruses are not considered a living thing because they lack most of the characteristics of life. they do not use food for energy or to grow, do not respond to surroundings, and cannot reproduce without a host.
what is the difference between asexual and sexual reproduction?
