rEtrIEvAL PRacTICe

100

Define Biotic and Abiotic factors

Biotic factors - all the living things in an ecosystem

Abiotic factors - all the nonliving things in an ecosystem

200

Rank the three types of radioactive decay in terms of their penetrating ability.

Gamma > Beta > Alpha

300

A wave has a frequency of 3.4 Hz and a velocity of 1.2 ms^-1

Calculate its wavelength.

v = frequency*wavelength

wavelength = v/frequency = 1.2/3.4 = 0.35 m

400

contrast eukaryotic and prokaryotic cells

Eukaryotes - have membrane bound organelles

Prokaryotes - do not have membrane bound organelles

500

Identify how each of the three systems below maintains homeostasis when your blood sugar spikes - 500 points for each correct answer. 

- Endocrine system

- Circulatory System

- Nervous System

Endocrine System - pancreas releases hormones into the blood that process the sugar

Circulatory system - carries the hormones from the pancreas to all of the affected cells

Nervous System - receptor cells in your pancreas are triggered and the nervous system is responsible for "turning the pancreas on"
