A student wanted to study the amount of mold growing on pizza at different temperatures. In the experiment, the student set up four identical pans of pizza. Each pan contained the same amount of pizza. The temperatures and light conditions are shown in the data table below.
One error made in setting up the experiment was that the four pans of pizza • were at different temperatures (2) had different ingredients (3) were different sizes (4) received different amounts of light
The results of one experiment carried out by a research team would be considered valid if 1. the experiment had no control setup2. all the members of the research team came to the same conclusion3. the experiment had more than one variable4. the experiment was repeated and the same results were obtained eachtime
The diagram below shows a rock suspended above an overflow container filled with water up to the overflow spout. A graduated cylinder is positioned next to the container to collect water that comes out of an overflow spout. Which property of the rock can be directly determined when the rock is placed in the overflow container? (1) mass (3) volume (2) density (4) hardness
The diagram below shows a triple-beam balance. What is the maximum mass, in grams, that could be measured by this balance? (1) 110 (3) 610 (2) 500 (4) 1510
1. What is the density of a 100gram object with a volume of 20 milliliters? 5g/ml 2. The object above was cut into three pieces. What is the density of one of those pieces? 5g/ml
Explain why an object placed in a glass of water floats. The object has a density less than the density of water (1g/ml).
Explain why an object placed in a glass of water sinks. The object has a density more than the density of water (1g/ml).
Below is a list of the densities of different object. Will each one float or sink in water? • 0.38 g/cm3 • 1.7 g/cm3 • 1.2 g/cm3 • 0.99 g/cm3 • 100 g/cm3 float sink sink float sink
1. Identify the structure used to focus the specimen under low power. E - Course adjustment 2. Identify the structure that gives you larger field of view. F - Low power objective 3. Identify the structure that adjusts the amount of light. F - Diaphragm 4. Identify the structure used to focus the specimen under high power. B - Fine adjustment 5. Identify the structure that gives a smaller field of view. D – High power objective E F F
What was the highest possible magnification that can be obtained when using this microscope? Objective - Ocular 40 x 10 = 400x E F
What happens to the amount of light in the field of view when switching from low to high power? The amount of light decreases (so the field of view gets darker) E F
What happens to the field of view when switching from low to high power? The field of view decreases (so you see less of the slide). E F
List the seven levels of classification from largest to smallest. Kingdom Phylum Class Order Family Genus Species
Explain the differences between a kingdom and a species. A kingdom is made up of the largest number of organisms while a species contains the smallest number. A kingdom consists of organisms that are not very similar to each other while a species consists of organisms that are most similar to each other.
Acer saccharum is the scientific name for the sugar maple tree. Acer is the name of the tree's • genus • phylum • species • kingdom
Some unicellular organisms can reproduce by the process of • meiosis (2) fertilization (3) metamorphosis (4) mitosis
Cancer is best described as (1) a type of genetic engineering (2) the merging of sex cells (3) abnormal cell division (4) tissue that stops growing
Identify each type of asexual reproduction below. Binary fission Budding Regeneration Vegetative propagation Vegetative propagation Sporulation
Compare and contrast binary fission and budding. Both process are types of asexual reproduction. Both processes involve mitotic cell division. Both processes produce offspring that are genetically to the parent. Binary fission is an equal division of cytoplasm. Budding is an unequal division of cytoplasm.
What kind of fertilization is taking place above? Explain why so many eggs are released during this process? What kind of organisms use this process? External fertilization To increase the chance of fertilization Aquatic organisms
Identify the structures labeled. 1 - cervix 2 – umbilical cord 3 - placenta 4 - oviduct 5 – amniotic fluid
4 - oviduct • Where did fertilization take place? • Where does the exchange of oxygen, nutrients and wastes occur between mother and fetus occur? • What protects the fetus? 3 - placenta 5 – amniotic fluid

Which species is most closely related? How do you know? Human and Chimpanzee The sequence of amino acids is identical.
Which concept would be correctly placed in box X? (1) use and disuse (2) variation (3) transmission of acquired traits (4) changes in nucleic acids
The diversity within the wild bird species in the diagram below can best be explained by which process? (1) natural selection (3) ecological succession(2) asexual reproduction (4) mitotic cell division
