Which of the following is the correct first step when constructing a line graph using the data table: Marimo Position in Light and Dark Conditions?
Mark an appropriate scale on each axis
Plot the data points
Connect the points
Label each axis
State the relationship between the light exposure and the position of the Marimo balls.
When the light is on, the Marimo balls are positioned higher (at 225-500 mL), and when the light is off, their position decreases (down to 100 mL).
When the light is on, the Marimo balls are positioned lower (at 100 mL), and when the light is off, their position increases (up to 500 mL).
The position of the Marimo balls remains constant regardless of light exposure.
The Marimo balls only move when the light is off, staying at the same position when the light is on.
Which statement provides evidence to explain how the changing climate will affect maple trees and syrup production in the future?
The optimal areas for maple syrup production will shift northward where temperatures are cooler.
The optimal areas where maple syrup was produced from 1950 to 1999 will stay the same in the future.
Future maple syrup production will mainly occur in latitudes between 38 and 42 degrees, since maple trees will be more successful in that range.
Maple trees will not survive in northern areas in the future, therefore maple syrup production will stop.
A survivorship curve is a model showing the number or proportion of individuals surviving to each age for a given species or group. The survivorship curves below are used to represent life expectancy patterns in three different species, A, B, and C. A student claimed that C best represents the survivorship curve of a Bluefin tuna. Which factor explains this claim?
Millions of eggs and sperm are released at the same time in the same area of the ocean.
An extremely small number of the young that hatch survive to adulthood.
The young migrate to a different region of the ocean upon reaching a certain size.
Because they practice cannibalism, approximately half of the young reach adulthood.
The illegal killing of elephants for ivory continues even though it is against the law because:
there is a high demand for ivory products
elephants are easy to protect
ivory has no value in the market
laws are strictly enforced everywhere
Researchers claimed that elephants were being poached for their tusks, which are composed of ivory. Based on data provided in the graphs (Global Ivory Sales and African Elephant Population Size), which statement best explains this claim?
Between 1977 and 2016, both graphs show a similar trend.
Between 1977 and 1989, ivory sales increased, and African elephant population size decreased.
Between 1980 and 2007, predators stopped preying on elephants, and the African elephant population size increased.
The hypothesis the experiment would test is that poison ivy is affected by air containing higher than normal concentrations of carbon dioxide.
Poison ivy is affected by air containing higher than normal concentrations of carbon dioxide.
Poison ivy grows better in low light conditions.
Poison ivy is unaffected by changes in soil moisture.
Poison ivy only grows in the presence of nitrogen-rich soil.
One way the control group should be treated differently from the experimental group when testing the effect of higher than normal concentrations of carbon dioxide on poison ivy is:
The control group should be exposed to normal air, while the experimental group is exposed to air with higher carbon dioxide.
The control group should receive more water than the experimental group.
The control group should be kept in the dark, while the experimental group is kept in light.
The control group should be given fertilizer, while the experimental group is not.
To test whether poison ivy is affected by air containing higher than normal concentrations of carbon dioxide, which two conditions should be kept the same in both the control and experimental groups?
Amount of sunlight and type of soil
Concentration of carbon dioxide and temperature
Type of plant and amount of fertilizer
Humidity and amount of water
To test whether poison ivy is affected by higher than normal concentrations of carbon dioxide, an experiment should be designed with controlled CO2 levels. Which of the following is a necessary safety precaution, and why is it important?
Wear gloves to prevent skin contact with poison ivy, as it can cause severe allergic reactions.
Ensure the experiment is conducted outdoors to avoid CO2 buildup.
Use only mature poison ivy plants to ensure consistent results.
Monitor temperature closely to prevent overheating of the plants.
Evidence from the graph that supports the claim that continued increases in atmospheric CO2 levels may impact sea urchin populations is:
Sea urchin populations decrease as atmospheric CO2 levels increase.
Sea urchin populations increase as atmospheric CO2 levels increase.
There is no change in sea urchin populations as CO2 levels increase.
Sea urchin populations fluctuate randomly with no relation to CO2 levels.
Base your answers to the question below on the information below and on your knowledge of biology. Tusklessness, not growing tusks, appears to be caused by a dominant allele (expressed/shown if present), carried by females and lethal (deadly) to males. The table below contains data on the change in the frequency of tusklessness in female African elephants. Female African Elephant Tusklessness Data Year | Sample Size | Tusked Females | Tuskless Females | Tusklessness % 1969 | 247 | 221 | 26 | 10.5 1972 | 205 | 180 | 25 | 12.2 1988 | 132 | 89 | 43 | 32.6 1989 | 165 | 102 | 63 | 38.2 1990 | 298 | 194 | 104 | 34.9 1991 | 171 | 114 | 57 | 33.3 1992 | 195 | 136 | 59 | 30.2 1993 | 279 | 199 | 80 | 27.7 10. Which statement about how humans affected the elephant population is supported by the evidence provided?
(1) The decrease in global ivory sales resulted in a decrease in tuskless male elephants.
(2) The chance of producing tuskless males increased as a result of the tighter enforcement on poachers.
The discovery that humans can inherit mitochondria from their fathers illustrates the concept that
inquiry does not judge the reliability of sources
experiments without controls are not valid
scientific explanations are tentative and subject to change
advancements in technology usually make scientific theories invalid
What is the volume of water represented in the graduated cylinder shown below?
10.3 mL
13.0 mL
14.0 mL
15.0 mL
A student set up an experiment to test the effect of the number of seedlings planted in one pot on the rate of growth. All conditions in the experiment were the same, except for the number of plants in each pot. The results are shown in the graph below. The dependent variable for this experiment was
the number of plants per pot
time in days
average plant growth
the amount of water per pot
A scientist is developing a system to remove harmful bacteria from a contaminated water supply. In order to trap the bacteria and prevent them from going through the filter, she must make sure the pores in the filter are no larger than
1 nm
1 μm
10 μm
100 μm
