Identify gland X [gland]. What is one function of this gland? [function]

Identify the endocrine gland indicated by the arrow. [structure] What does this gland regulate? [function] What regulates this gland? [regulate]

What endocrine gland is indicated by the arrow? [gland1] Indicate one other gland that this one regulates/controls. [gland2]

Identify gland X. [gland] What hormone is produced here? [hormone]

Endospore formation occurs when  [answer1]. For this process to occur, a [answer2] cell division is involved. During the process, the mother cell [answer3] the developing endospore. The endospore that is released [answer4] metabolically active and it has a high degree of resistance to environmental stresses.

Some halophilic archaea can grow as photoheterotrophs. Is the following true or false about this type of metabolism? These organisms have a unique protein called bacteriorhodopsin that can directly convert light energy into a proton gradient.

You are studying a novel species of Archaea that can be found in ocean sediments and you find that it has a generation time of 75 minutes, using binary fission to divide. If you start with a population of 1000 cells in a culture, how many cells will there be after 5 hours of incubation? Show your work or explain your answer.  

Some microbes can grow at pH extremes. True/False. These cells have an neutral internal pH despite the external pH.

You make up a liquid medium containing the following ingredients (each in sufficient quantities for growth): potassium phosphate, magnesium chloride, ammonium sulfate, glucose, and trace elements. You can assume that atmospheric gases (oxygen, carbon dioxide, nitrogen gas) are available. Would you expect a prototrophic chemoheterotrophic microbe to grow in this medium?  

Both E. coli and the mollicutes are chemoheterotrophs. What is one difference in terms of growth features between these two types?
