When you tutor Biology 12, you cover the circulatory system. Pretty much everyone knows arteries and veins are different. However, we’ll focus on their similarities first: 1) They both contain a reinforcing layer of smooth muscle. 2) For both veins …
Tutoring Biology 12, you cover human digestion – which mentions bile. Bile is an oft-referred-to secretion: in literature, it’s related to anger. Specifically, if someone’s “bile is up”, they’re in a bad mood. I don’t understand the association, but there …

Tutoring biology 12, the six (or so) functions of water in the human body comprise an early theme. Everyone knows water is important in the human body, but what are the precise reasons? 1. Water is liquid at body temperature. This …
Tutoring Biology 12, you sometimes talk about recombinant DNA. We’ll briefly look at what it is and why it’s used. Recombinant DNA (rDNA) contains DNA from more than one organism. The industrial uses I know of involve inserting specific genes from one species into …
When you tutor high school biology, cell biology is a mainstay. The particular role of the cell membrane sometimes gets neglected. Membranes are very important in the construction of organisms. Every membrane has the basic function of keeping materials separate or else keeping …
When you tutor biology or any science, often the basic concept is better without all the extra details thrown in. The renal artery brings blood to the kidneys to be filtered. Upon reaching a kidney, the renal artery branches into thousands of arterioles, …
When tutoring Biology 12, terms involved in the scientific method need definition. Let’s look at some. In an experiment, there is one variable whose value you must wait to see, and (at least) one that you purposely set. The variable you …
