Most scientists agree that a large asteroid struck Earth around 65 million years ago. The impact sent large amounts of fine dust particles into the atmosphere, which reduced the amount of sunlight reaching the planet. This event would have the most immediate effect on
herbivores
carnivores
decomposers
autotrophs
An example of how a plant maintains homeostasis includes
producing many seeds for reproduction
controlling the amount of available solar energy
recycling energy from the Sun
regulating the action of guard cells
The structures most directly involved in the synthesis of cellular proteins are the
nucleus and ribosomes
cell membrane and nucleus
chloroplasts and cell membrane
mitochondria and chloroplasts
Potato plants reproduce both sexually and asexually. Depending on the desired outcome, potato growers use both types of reproduction. A grower would most likely want the potato plants to reproduce asexually when
selectively breeding new potato varieties
there is a disease affecting similar potatoes growing in the area
environmental conditions in the area are changing
potatoes with the same traits are desired
Which statement best describes the offspring that result from these methods?
Both models A and B produce offspring that have fewer chromosomes than the parent cells.
Both models A and B result in offspring that have more chromosomes than the parent cells.
Model A produces offspring with genetic information different from the parent. Model B produces offspring that are genetically identical to the parents.
Model A produces offspring with identical genetic information to the parent cells. Model B produces offspring that are genetically different from the parent cells.
Which two processes are directly required for a human zygote to be produced?
mitosis and fertilization
meiosis and fertilization
mitosis and differentiation
meiosis and differentiation
This single-celled organism is maintaining homeostasis by
limiting the number of the molecules of A that it excretes
eliminating molecules of compound B
excreting molecules of compound C
using sunlight to increase the number of food molecules that it takes in
Which explanation is consistent with the data collected?
The increased mass of the willow tree came only from materials taken in from the soil in which it was planted.
The increased mass of the willow tree was the result of cellular respiration during the five-year period.
The willow tree did not use any material from the soil during the five-year period.
The increased mass of the willow tree was the result of the tree taking in materials from its environment.
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
simple sugars
water
carbohydrates
Traits are passed from parents to offspring. These traits are determined by
chromosomes, located on genes, found in the nucleus
genes, located on chromosomes, found in the nucleus
chromosomes, located on genes, found in the ribosomes
genes, located on chromosomes, found in the ribosomes
Two kittens in a litter are genetically different from each other and from their parents. These genetic differences are most directly due to
sexual reproduction
asexual reproduction
cloning
evolution
The substance responsible for breaking down the Venus fly trap’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
Euglena will most likely act as consumers when placed in an environment that has
an acidic pH
a low oxygen level
little or no light present
many predators
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
proteins from animal prey
carbon dioxide from the atmosphere
carbohydrates from the soil
Explain why most human cells require a supply of glucose
After 20 minutes, the section of paper towel connecting the two beakers had turned color. The towel most likely turned green as a result of the
separation of the dye molecules through the process of chromatography
dyes moving across the towel due to the process of electrophoresis
diffusion of the blue- and yellow-dyed water across the towel
active transport of the blue and yellow food dyes
State one biological explanation for how the pulse rate increase benefi ted the student as he exercised.
When compared to organisms that utilize process A, organisms that utilize process B would most likely produce offspring with
a greater variety of genetic combinations (2) (3) (4)
fewer genetic differences
more genetic combinations
more DNA within each nucleus
How many chromosomes will be in the skin cells of her offspring?
124
31
62
30
Which biological process is represented in the diagram below?
photosynthesis
digestion
respiration
replication
The diagram below shows specialized plant cells that control openings called stomates.
The proper function of these cells is vital to the survival of the plant because they regulate the
rate of glucose use by root cells
absorption of sunlight by leaf cells
products of photosynthesis in the stem
exchange of gases in leaves
Although the Venus flytrap uses its prey to obtain certain molecules that it needs, it is still classified as a producer because it
uses its prey to produce food
consumes the prey to produce energy
synthesizes energy by using oxygen and releasing carbon dioxide
synthesizes glucose by using carbon dioxide and water
Sometimes a hypothesis is not supported. Yet, scientists consider the findings valuable. State one reason scientists would value an experiment that does not support the initial hypothesis.
Which characteristic is common to most types of cancer?
production of low levels of ATP
inadequate levels of antigens
rapid and uncontrolled cell division
destruction of red blood cells
