By studying the fossil record we can tell how long life has existed on Earth, and how different plants and animals are related to each other. Often we can work out how and where they lived, and use this information to find out about ancient environments. Fossils can tell us a lot about the past.
Answer: You are correct!
A prokaryote is a single-celled organism that lacks a nucleus, and other membrane-bound organelles. Ex) blue-green algae, <u>bacteria</u> and mycoplasma
A eukaryotic cell is any cell or organism that possesses a clearly defined nucleus. Plant and animal cells are classic examples of this.
When you think about it, structure is often but perhaps not always necessary for function of a certain ability in any organism.
Wings for example give organisms the ability to fly, so the structure of their wings enables them to fly. Without wings, they wouldn't be able to fly (excluding free fall or using technology).
Also important is too understand that we adapt through changing our abilities - function ever so slightly from generaton to generation to adapt to a certain environment where we live, this can then change structure accordingly to ensure proper function for the new ability.
Answer: Botulism (Clostridium botulinum)
Botulism is caused by
a bacterial infection specifically <span>Clostridium botulinum,
an anaerobic, gram-positive spore forming rod, whose spores survive in soil and
water. This toxin acts by blocking nerve
function by inhibiting release of acetylcholine neurotransmitter that results
to muscular rigidity and spasms of respiratory, laryngeal, and abdominal
muscles, which may cause respiratory failure. </span>
To repopulate and introduce species into the wild
