Population Size & Density
5.
What is the equation used to calculate population density? Label the terms.
6.
If there are 400 moose living in a 600ha region of Algonquin Park, what is the population density?
7.
What is the difference between crude density and ecological density
?
SBI4U – Gr. 12 Biology Univ. Prep.
8.
What density is represented in question #6 – crude density or ecological density? Why?
9.
Redo question #6, this time accounting for a 70ha lake in the habitat. What type of density accounts for this?
10.
What is population dispersion?
11.
What are the 3 patterns of population dispersion? Draw a picture & give an example of an animal for each.
Measuring Population Characteristics
Populations are “dynamic” – they keep changing! Thus, it is hard to count numbers of animals in a population. Researchers count numbers at a specific time & estimate/predict population numbers based on these numbers.
12.
Describe quadrat sampling. What type of species is this type of sampling good for?
SBI4U – Gr. 12 Biology Univ. Prep.
13.
You want to estimate the number of ragweed plants growing in a large field, 100m x 100m. You place a quadrat (3.0m x 2.0m x 2.0m) down on the field in 3 different spots and count the number of plants in each quadrat. Your results are 18, 11 and 24 plants.
a.
What is the population density of ragweed in the field?
b.
What is the population size of ragweed in the field?
14.

ASSIGNMENTS FOR CHAPTER 4.
1. Assignment 1: By using the general equation N = No × 2ª where Nt
is the number of cells at given time (in minutes) and No is the initial
number of cells, and "n" is the number of generations at that point
(number of cell division), calculate how many cells you will have in
30, 60, 90, and 120 minutes if your bacteria has a generation time
of 30 minutes and you start with 100 cells at 0 time.

Case study (Activity 1.3)
Mountain Top Primary School is situated in a beautiful environment in the mountains. The school consists of eight classes, one for each grade. Although the buildings are fairly old, the school is well equipped, and the teachers have all the resources they need. Much of the teaching and learning is done outdoors with a focus on the local natural resources. The learners are encouraged to be active in their community and help each other. Social and spiritual values are emphasised.
The principal is supportive of everything that the teachers plan. Planning means that each teacher decides on relevant content and adapts the CAPS document according to what learners are interested in. Planning is seen as a dynamic process and…

Scientists collected data on two groups of organisms. The mean, x, equals 15 for the
first group and 7 for the second group. In each group, the sample variance, s2, equals
3. The sample size, n, for the first group is 10 and for the second group is is 11.
Calculate the t-value for these two groups of organisms. Then, explain the next two
steps that are needed to determine if this t value is statistically significant.

Each ionizable group of an amino acid can exist in one of two states, charged or neutral. The electric charge on the functional
group is determined by the relationship between its pK and the pH of the solution. This relationship is described by the
Henderson-Hasselbalch equation.
Histidine has three ionizable functional groups. Complete the equilibrium equations by assigning the proper pK₁ for each
ionization and the net charge on the histidine molecule in each ionization state.

Skill 3: Identifying Types of Data
Sys
Hypotheses are tested by evidence collected in the form of scientific data, or
information obtained using specific analytical methods as part of an experiment or
empirical observation. Scientific data can be qualitative or quantitative. Quantitative
data are expressed as numeric values, rendering observations more objective and
quantifiable, and can be either discrete of continuous. Discrete data can only take
certain values (such as whole numbers), whereas continuous data can take any value
mei
within a range and can be represented by fractions and decimals. Qualitative, or
categorical, data are descriptive, pertaining to properties that are difficult or
impossible to express numerically, such as aspects of behavior or complex shape.

Question 9 (1 point)
Often, a large collection of data points are generated and graphed as a scatter plot
and then a line can be added. What purpose does the line serve?
To show the overall trend in the data to understand potential relationships
between the variables.
To connect all the dots so the sequence of data collection can be represented.
It will enable us to remove all the random dots and just keep the line so the
graph isn't so messy.
