At what pH are both enzymes working?
Exam the image carefully.
Although these organisms belong to the same phylum, they are classified as different —
families
species
kingdoms
orders
Why is it best for scientists to use the scientific name from the standardized taxonomic system?
Communication with other scientists about fish
will be reduced.
The common names can be confusing when
identifying organisms.
The scientific name is
less descriptive of the organism.
The scientific name
differentiates seahorses from ringworms.

The four eukaryotic kingdoms are Protista, Fungi, Plantae and Animalia.
(a) - mostly multicellular, absorbs nutrients extracellularly
(b) - multicellular, depend on other organisms as their source of energy
(c) - multicellular, only kingdom that is solely autotrophic
(d) - mostly unicellular, most live in water
The table below shows two human body systems. Place the two correct organs that complete the table.
Our bodies have levels of organization that build upon each other. Our (a) make up tissues, (b) make up organs, and organs make up (c) .
Label the biological levels of organization.
Which sequence best describes an interaction between the integumentary and excretory systems that helps maintain homeostasis?
Heart rate increases → Blood vessels constrict
→ Blood pressure increases
Blood vessel is damaged → Platelets begin to clump → Blood vessel ruptures
Blood sugar levels rise → Pancreas secretes insulin → Blood sugar continues to rise
Body temperature increases → Glands release sweat → Body temperature decreases
The (a) system consists of a group of organs that help break down food into nutrients and simpler substances. The (b) system helps transport these nutrients and substances throughout the body, and into the cells. Food that is undigested moves through the large intestine, and is eliminated from the body through the (c) system.
Nervous System
sends and receives signals
Immune System
protects against pathogens
Muscular
moves skeletal frame
Integumentary
first line of defense
Endocrine
creates hormones
Which statement best describes an interaction that will allow a flowering plant to reproduce by self-pollination?
An anther is transferred from a filament to another filament within the same flower.
An ovule is transferred from the ovary to a petal on a different flower.
A pollen grain is transferred from an anther to the stigma of the same flower.
An ovary is transferred from a flower on one plant to a flower on a different plant.
Which terms best complete the numbered blanks in the flowchart?
Leaf-cutter ants harvest leaves and carry them to fungi that convert plant material into a usable form for the ants to digest. The fungi depend on the leaves for nutrients. The ants also produce an antibiotic on their bodies that helps protect the fungi from harmful bacteria.
Predation, because the ants feed on the fungi
Mutualism, because both the ants and the fungi benefit from each other
Competition, because both organisms consume the same resource for energy
Commensalism, because the ants receive energy from the fungi and the fungi are unaffected
A dog walks around a neighborhood marking different objects with urine to mark its territory. The smell will alert other animals that a dog is in the area and may defend the area against unknown animals. The territorial display is an example of what type of relationship?
Predation
Mutualism
Competition
Commensalism
(a) is the type of symbiosis in which one individual benefits while the other individual neither benefits nor is harmed
(a) is a type of symbiosis in which both individuals
benefit.
What is the order of the taxonomic levels from least specific to most specific?

Which of the following statements best describes phloem's function in the plant?
transports water and minerals up from the roots to the rest of the plant
transports food down from the leaves to the rest of the plant
transports water and minerals down from the roots to the rest of the plant
transports food up from the leaves to the rest of the plant
Which of the following functions do xylem tissues perform?
carries a watery sugar mixture from the leaves to the roots
carries a watery sugar mixture and minerals from the roots to the leaves
carries a water mixture and minerals from the leaves to the roots
carries a water mixture and minerals from the roots to the rest of the plant
Which of the following is the correct equation for PHOTOSYNTHESIS?
light + carbon dioxide + water --> glucose + oxygen
carbon dioxide + sugar + water --> oxygen + light
oxygen + light + water --> carbon dioxide + sugar
carbon dioxide + oxygen + water --> Light+ Sugar
What is the role of auxin that causes a plant to bend towards light?
The concentration of auxin in the plant increases when there is light.
Auxin causes uniform growth on every stem.
Auxin causes cells that are on the dark side to grow faster.
Auxin causes the increase in the number of plant cells.
Plants respond to external stimulus is called tropism. Plant respond to Light (a) , Plant respond to gravity (b) , Plant respond to touch (c) and Plant respond to water (d)
