The gray squirrel, Eastern fox squirrel, and red squirrel are all different species of squirrels. Why is having a scientific name for each species of an organism important?
To prevent existing named organisms from having their names changed as they become extinct
To keep the classification system from being altered as new organisms are discovered
To allow organisms to be placed in many classification levels at the same time
To standardize the naming and organization of organisms to avoid confusion
Organisms are classified today using the Linnaean system, and the following table shows the taxonomic classification of two marine organisms living along the Pacific Coast.
Taxonomic classification is important to marine biologists because it provides a way to -
prove that marine evolution occurs
discover and name every marine organism on Earth
designate Latin as the universal language of marine biology
identify marine organisms and find evolutionary relationships between them
Scientists around the world use a standardized taxonomic system. Why would scientists want to use a taxonomic system that is standardized?
In order to avoid confusion with the identification of organisms
Because Linnaeus established the system
So that Latin names can be applied for a practical purpose.
In order to place organisms in different groups
The Linnaean taxonomic system classifies organisms into divisions called taxa. If two organisms belong to the same taxonomic group, they are related. Similarity at which of these levels indicates the closest relationship?
Kingdom
Class
Order
Genus

Many tree frog populations are threatened due to habitat loss. In an effort to promote conservation, tree frogs may be bred in captivity. A zoo acquired male and female tree frogs from two different populations. In the zoo, the tree frogs were able to successfully mate within their own population, but breeding attempts between the two populations were unsuccessful.
Based on this information, which statement correctly describes the relationship between the two populations of tree frogs.
They are in the same species but different kingdoms.
They are in the same class but different phyla.
They are in the same family but different orders.
They are in the same genus but different species.

In 1898 Friedrich Loeffler and Paul Frosch found evidence that the cause of the highly contagious hoof-and-mouth disease in livestock was a microscope infectious particle. It was discovered that this particle requires a host cell to reproduce.
Which pathogen is most likely responsible for causing hoof-and-mouth disease in livestock?
a bacterium, because it is contagious
a fungus, because it infects livestock
a protist, because it is microscopic
a virus, because it requires a host cell to reproduce
Which of these describes a difference between viruses and cells?
Cells contain protein, and viruses contain only carbohydrates.
Viruses have flagella, and cells have only cilia.
Cells are living organisms that can get and use energy. Viruses are non-living and can not get or use energy without a hot
Viruses have membranes, cytoplasm and ribosomes, cell have capsids and spikes.
The human immunodeficiency virus (HIV) often infects and destroys CD4 T-cells. These CD4 T-cells are one of many kinds of white blood cells that are an important part of the immune system, which protect the body.
The most common danger related to the destruction of CD4 T cells is -
an increase in the risk of high blood pressure
an increase in the threat of diseases caused by microorganisms and viruses
a decrease in the flow of blood to vital organs
a decrease in the amount of oxygen being transported to issues.
The picture shows a 3D model of a virus called a bacteriophage. Bacteriophages can infect bacteria such as E.coli.
In what way are the bacteriophage and E.coli alike?
they contain antibodies
they reproduce by mitosis
they have identical genomes
they lack membrane-bound organelles
Gibberellins are hormones produced in the root tips of plants. The plant uses these hormones to stimulate the growth of shoots.
How are gibberellins able to affect other parts of the plant?
Gibberellins are absorbed through the stomata and attach to chloroplasts.
Gibberellins are transported through vascular tissues to other parts of the plant.
Gibberellins become concentrated within the tissues of the plant during mitosis.
Gibberellins become modified once they infect healthy cells and are later released to infect other cells.
A chart of some plant systems and functions is shown.
Which system interactions are dependent on the plant's ability to respond to the direction of light?
Option 1
Option 2
Option 3
Option 4
Plant roots have extensions called root hairs. These root hairs. These root hairs are important in the homeostasis
of the plant.
Which statement best explains the importance of the root hair to the stems and leaves of the plant?
Root hairs convert minerals into glucose for immediate use by cells.
Root hairs decrease the need for osmosis and diffusion in vascular tissue.
Root hairs prevent water loss in leaves through transportation and gas exchange.
Root hairs increase the surface area of the roots for nutrient and water absorption.
A corn plant produces both male and female flowers. The male flower forms the tassel and the female flower forms the ear of corn. The silk that emerge from the ear are the stigma of the female flower. Each silk leads to an ovule that can become a corn seed.
Which of these must happen for corn seeds to develop on the ear?
More tassels that silks need to be present on the same plant.
Pollen grains must fall from tassels and land on the silks of the ear.
Pollen must be transported from the tassel to the silk through the phloem.
The tassels must come into direct contact with the silks of the ear.
Fruits grown in hot climates are usually less sweet than those grown in cooler temperatures. The high temperatures increase the rate of respiration in the plants, thus reducing the sugar content in some fruits.
Why does increased respiration in the leaves and stems reduce the sugar content in the fruits of a plant?
Chloroplasts move from the fruits to the leaves and stems to provide energy for respiration.
The flow of nutrients shifts from the phloem to the xylem, moving nutrients away from the fruits.
Sugars are moved from the fruits to the roots for storage.
Sugars produced in the leaves are used as an energy source instead of being stored in fruits.
In which type of plant does water/food move through xylem and phloem?
seed plants
vascular plants
non-vascular
both vascular and non-vascular
What material makes up plant cell wall
Chitin
