Humans are bipedal, terrestrial omnivores. As a species, we are adapted to quite a range of habitats, from deserts to mountains and from rain forests to tundra. Ultimately, however, we are descended from early hominids who evolved in African plains, and our body systems tend to reflect this. Your job is to determine how humans might be adapted to specific environments if they had evolved to eat a herbivorous diet (grasses or leaves).

Write a brief description of the digestive system, and why it would look the way it does. Consider the following:

  • What would be required to eat, chew, swallow, break-up, digest, and extract nutrients? You are encouraged to look up other (non-human; can be non-mammalian) animals that share this diet for ideas.
  • What if humans were not omnivores, but had evolved for a different food source? In other words, it would still look *basically* like a human but would have some important differences related to its diet.
  • What would the digestive system of a human that adapted to a different food system look like, and why would it look like this?
  • You should consider the following parts of the digestive system in your answer: Mouth & teeth, Stomach & upper digestive tract (including crop & gizzard if relevant), Intestines, and Accessory organs (spleen, gall bladder, liver).

I have a question about qPCR.
How to measure an mRNA level of a gene by qPCR. If I perform a realtive quantification qPCR, first I need to convert mRNA into DNA template by Reverse transcriptase. then I perform a qPCR reaction. For example, comparing with the reference gene, the drug treatment lead to a decrease in the expression of gene of interest. However, I think that can only determine the gene replication is inhibited because the pcr reaction is DNA replication , not DNA transcription. So, how can I know the difference in amount of mRNA in a cell?

1. Explain in your own words why regulation is important. I would like you to use 2 examples, one from human communities and one from the human body in your explanation. Make sure to include how regulation is enabled in each case (i.e. how is communication occurring?).

2. In order for an effector to respond to a command via either of the endocrine or nervous system, it must be able to respond to a chemical (hormone or neurotransmitter). Explain how the effector is able to respond to these chemical signals (i.e. what must it have either in its membrane or inside its cells). Describe how this process of intercellular communication exemplifies the relationship between structure and function.
