There are over 2000 kinds of edible insects in the world, and they are becoming an increasingly popular source of protein. One cup of cricket flour contains over 28 grams of protein. The building blocks of the protein in cricket flour are
amino acids
water
simple sugars
carbohydrates
Protein synthesis is accomplished primarily by the interaction of which two cell structures?
vacuoles and mitochondria
ribosomes and vacuoles
nuclei and ribosomes
nuclei and mitochondria
In which cell structure is energy extracted from nutrients?
chloroplast
mitochondrion
ribosome
vacuole
The Venus flytrap is a Plant that has a unique system by which it traps and breaks down its prey. Unsuspecting insects land on the leaf and touch tiny hairs located on the leaf triggering the leaf to close around the prey.
The substance responsible for breaking down the Venus flytrap's prey most likely contains
chlorophyll molecules
glucose molecules
hormone molecules
enzyme molecules
It may be harmful when people compete to see who can hold their breath the longest underwater. Without oxygen, brain cells
cannot make enough ATP
have too few mitochondria
make too many enzymes
have too much water
Students did an experiment comparing the
activity of four different enzymes, A, B, C, and D.
The results are represented in the graph below.
A valid conclusion based on the information in the graph is that
the pH of some enzymes changes as the temperature changes
enzymes change color in proportion to the rate of activity
a difference in the pH of an environment changes enzyme activity
enzyme activity causes acids to change into bases over time
A small lizard spends the morning hours lying in the sunlight until its body temperature rises. Later on in the day, the lizard rest in a shady area until its body temperature cools. This type of behavior is important to
maintain homeostasis
detect variations
attract mates
obtain nutrients
The diagram below represents changes that take place within the human body.
The diagram represents
cellular differentiation
biological evolution
gene interaction
dynamic equilibrium
An experiment is carried out to determine how different pH values of soil will affect the growth of tomato plants. In this experiment, the dependent variable could be the
height of the tomato plants
pH of the soil
specific variety of tomato plants used
pH of enzymes in tomato leaf cells
Using microscopes he constructed in the 1600s, Antonie van Leeuwenhoek discovered a new microscopic world. His discoveries paved the way for the development of the microscopes used today and for many important biological breakthroughs.
Which statement best describes van Leeuwenhoek's work?
His observations alone provided enough information to form modern biological theories.
The microscopes he made were used by all scientists and have remained unchanged over the years.
Knowledge gained by his work has led to the improvement and
development of modern scientific concepts.
Explanations of the microscopic world today are solely based on his observations and conclusions.
In the 1660s, Flemish physician Jan van Helmont grew a small willow tree in a pot of soil. He added only water to the pot. At the end of five years, he found that the tree had gained 75 kilograms, but there was very little change in the mass of the soil. Van Helmont concluded that the plant gained weight directly from the water. We now know that this conclusion is only partially correct because, in addition to water, photosynthesis also requires
oxygen from the atmosphere
carbon dioxide from the atmosphere
proteins from animal prey
carbohydrates from the soil
Sailors in the past may have heard the greeting from a passing ship, "Avast ye scurvy dog." This greeting would be a reference to a disease known as scurvy, which is due to inadequate intake of Vitamin C. Which row in the chart below correctly identifies the cause of this disease and a possible treatment for it?
Row 1
Row 2
Row 3
Row 4
