Your friend José, who's an art major, learned a startling fact: that our lower intestines are bursting with microbes; containing a "million's million" colony forming units per milliliter (or 1012 cfu/ml).

As a microbiologist, what would you tell your alarmed friend?

A) That this value is an underestimate of the true number of microbes in our lower intestine.

B) That this value is an overestimate of the true number of microbes in our lower intestine.

C) That this value is a fairly accurate estimate of the true number of microbes in our lower intestine.

D) That although surprising, that the number of microbes on the surface of our skin is even higher.

What are two ways in which waves erode the land?

In eukaryotes, genetic information is passed to the next generation by processes that include mitosis or meiosis. which of the explanations identifies the correct process and supports the claim that heritable information is passed from one generation to another? a. mitosis, followed by cytokinesis, produces daughter cells that are genetically different from the parent cell, thus insuring variation within the population. b. during mitosis, dna replication occurs twice within the cell cycle to insure a full set of chromosomes within each of the daughter cells produced. c. in asexual reproduction, a single individual is the sole parent and passes copies of its genes to its offspring without the fusion of gametes. d. single-celled organisms can fuse their cells, reproducing asexually through mitosis to form new cells that are not identical to the parent cell.
