- Q1
When the carrying capacity for a species in a habitat is reached, the population of the species levels off. This slowing of the rate of growth is most likely due to
limited resources
an increase in decomposers
renewable energy
a lack of competition
30sS4-K6.6.1 - Q2
On a hot day, dogs sweat through their paw pads and pant, which helps keep them cool. Both the sweating and panting are
a failure of cell communication
a response to a stimulus
due to a lack of adaptation to the environment
due to a loss of oxygen
30sS4-K5.5.1 - Q3
The formation of the many kinds of body cells that make up an embryo begins with
the clumping together of proteins within the cells
chemical changes in the cell membranes
the rapid metabolism of sugar molecules
specific genes being activated
30sS4-K2.2.2 - Q4
Some salmon have been genetically modified to grow bigger at a faster rate than wild salmon. They are kept in fish-farming facilities and are not released into the wild. Which statement regarding genetically modified salmon is most likely true?
Genetically modified salmon and wild salmon would have identical DNA sequences.
Wild salmon reproduce sexually, while genetically modified salmon reproduce asexually.
Wild salmon have an altered protein sequence, but genetically modified salmon do not.
Genetically modified salmon and wild salmon would have different DNA sequences.
30sS4-K2.2.2 - Q5
A farmer stopped maintaining a field that was once used to grow crops. Over time, the field eventually became a forest. These changes best illustrate the process of
ecological succession
decomposition
competition
nutrient recycling
30sS4-K6.6.3 - Q6
During a woman’s menstrual cycle, ovulation occurs and an egg is released. This process is important because it allows for
eggs to be produced by mitosis and be fertilized by a sperm
sperm to fertilize the egg in the uterus
multiple sperm to fertilize one egg, which then forms the placenta
the egg to leave the ovary and be fertilized by a sperm
30sS4-K4.4.1 - Q7
The primary function of estrogen and progesterone is to
control heart rate
regulate growth
regulate reproductive cycles
monitor blood sugar levels
30sS4-K4.4.1 - Q8
Which characteristic is common to most types of cancer?
rapid and uncontrolled cell division
destruction of red blood cells
inadequate levels of antigens
production of low levels of ATP
30sS4-K5.5.2 - Q9
The human body fights an infection when a pathogen is detected. As a result, the pathogen stimulates the production of
vaccines
antibiotics
antibodies
bacteria
30sS4-K5.5.2 - Q10
Levels of organization in humans are represented below.
Level X most likely represents
ribosomes
molecules
organelles
tissues
30sS4-K1.1.3 - Q11
A biological process is represented below.
The reason the hormones affect the target cell and not the other cells is that the
target cell has specific receptors for the hormone
hormone provides energy only for the target cell
hormones can only leave the bloodstream near the target cell
nontarget cells produce antibodies that block the hormone
30sS4-K1.1.2 - Q12
The diagram below represents one of a number of different types of mutations that can occur in DNA.
This mutation can best be described as the
the substitution of an adenine (A) base for guanine (G)
deletion of an adenine (A) base from the DNA molecule
pairing of an adenine (A) base with thymine (T)
the insertion of an adenine (A) base into both strands of the DNA molecule
30sS4-K2.2.1 - Q13
After digesting the nutrients from a meal high in carbohydrates, the body
releases insulin to return the blood sugar levels to normal
produces water to maintain dynamic equilibrium in the blood
maintains homeostasis by increasing wastes produced in muscle cells
secretes enzymes to absorb starch into the intestines
30sS4-K5.5.1 - Q14
The diagram below represents a pair of guard cells changing shape, reducing the size of the stomatal opening in a leaf.
This is an adaptation that benefi ts plants by
increasing the flow of oxygen molecules into the leaves, which increases the rate of photosynthesis
regulating the flow of water vapor out of leaves, preventing excess water loss by the plant
increasing the flow of liquid water into leaves, which increases the rate of food and oxygen production
preventing the fl ow of carbon dioxide into the leaves, which would reduce the rate of respiration
30sS4-K5.5.1 - Q15
Experiments in mice show that a guardian gene that protects against type 1 diabetes can be altered by exposure to antibiotics during development. The exposure alters the gut bacteria, leading to a loss of the guardian gene’s protection. The loss of this protection most directly interferes with
respiration
homeostasis
excretion
reproduction
