list some characteristics of life you observed by the water bear: list some observations about the water bear and why its apparently so successful in a variety of environments

Expert Solution

Water bear - Tardigrades ( phylum of small invertebrates). Tardigrades are short (0.05mm - 1.2mm in body length), plump, bilaterally symmetrical, segmented organisms. They have four pairs of legs, which further divides in four to eight claws. Tardigrades reproduce via asexual (parthenogenesis) or sexual reproduction and feed on the plant cells, animal cells, and bacteria.They have an amazing diversity of habitats and can be found in almost every habitat.

Tardigrades have adapted to environmental stress by undergoing a process known as cryptobiosis. Cryptobiosis is defined as a state in which metabolic activities come to a reversible standstill. It is truly a death-like state. The most common type of cryptobiosis studied in tardigrades is anhydrobiosis (lack of water).

Note- All Tardigrades need water around their bodies to permit gas exchange as well as to prevent uncontrolled desiccation.

What are some characteristics of a normal distribution? What does the empirical rule tell you about data spread around the mean? How can this information be used in quality control? Can you compare apples and oranges, or maybe elephants and butterflies? In most cases the answer is no – unless you first standardize your measurements. What are a standard normal distribution and a standard z score?
