What topics really confused you?
The most confusing was some parts of the Biochem chapter.
What topics do you feel very clear on?
Plants because it's the most recent.
What lab/ activity was your favorite? Why?
The best would be the Osmosis one because it was a collaborative effort between different group.
What lab/activity was your least favorite? Why?
The online Fly one because I didn't really understand how to record the data.
If you could change something about the class to make it better, for instance the type of homework (not the amount) what would it be and why?
More lectures and maybe make the powerpoints you used in the lectures available online.

Genomes: Chapter 16 Memory
Summary: Basically chapter 16 is about the 16th chromosome which lies the key to learning and memory. It also compares instinct with learning as learning is often considered the more "advance" thing to do. However, humans also do many things instinctively such as blink, breath, walk, etc. James Mark Baldwin argued that "consciousness" is for learning thing that nature failed to instill within us , but gradually what we "learned" will become instinct. The chapter goes on to explain memory in terms of genes and how thought the brained is programed by said genes it is a machine designed to learn and modify with eperience.

Extreme Organism
Alkaliphiles are microbes that thrive in alkaline-rich environments (with a pH of 9 to 11) . For example playa lakes and carbonate-rich soils. To survive, alkaliphiles maintain a relatively low alkaline level inside their cells.

Bacteria, Viruses, Prions
Bacteria
Bacteria are unicellular prokaryotes that can reproduce even in isolated environments and generally reproduce through the process of binary fission. Bacteria have circular double stranded DNA and unlike viruses and prions can produce their own proteins and enzymes to carry out metabolic processes.
Virus
Viruses need a host to reproduce itself. Viruses can choose to reproduce by infecting a cell then using the celll to replicate itself and going out to infect more cells. Viruses needs to use the hosts' DNA to make their own DNA.
Prions
Prions are infectious proteins that usually occur in the brain and is created when a normal brain cell is transformed into a prion. Eventually this can cause cellular malfunction and brain degeneration.

Major Plant Divisions
Charophyceans
Charophyceans are the green algae most clearly related to land plants. They seem to share many characteristic typical of a land plant.
Bryophytes
Bryophytes include the mosses, liverworts, and hornworts. They live in moist areas because of their lack of vascular tissue. They reproduce using spores with reproductive structures of gametangia and sporangia.
Pteridophytes
Are vascular plants, which contain xylem and phloem. Horsetails, ferns, club mosses, and quillworts are pteridophytes. Instead of producing flowers or seeds, they produce spores, but do have true roots, stems, and leaves.
Gymosperms
Gymnosperms include trees such as conifers, cycads, and ginkgo. Theses are a group of seed-bearing plants, the seeds of the gymnosperms are unenclosed and are called ovules in their unfertilized state.
Angiosperms
Angiosperms produce seeds, but also produce flowers which contains their reproductive organs. The seeds are enclosed during pollination and produce fruit. The fruit then produces more seeds.

Lives of a cell
Although, humans would like to think they have a mastery over nature this is not true. We are a part of nature. The very processes that keep us alive are a part of nature. Our lungs would not keep functiong if not for our cells. We would not even exist again without our sells.
