Which statement best summarizes the importance of meiosis to reproduction?

It produces diploid cells that are needed for sexual reproduction.

It produces diploid cells that are needed for asexual reproduction.

It produces gametes that are needed for sexual reproduction.

It produces gametes that are needed for asexual reproduction.

A species of mud snail was studied for five years. During this time, scientists observed the season in which they mated, the number of offspring they produced, and the results of such stressors as drought, famine, and lack of mates. Which question were the scientists most likely studying?

What is the food source most often chosen by the mud snail?

Are the reproductive rates of mud snails affected by environmental changes?

Are mud snails more likely to choose mates with colorful shells?

Do mud snails prefer to live in water or near a water source?

Fewer offspring is a disadvantage of which form of reproduction?

mitosis

asexual reproduction

binary fission

sexual reproduction

Sheela wants to demonstrate the importance of photosynthesis to plants and the other living organisms that eat plants. She models the process of photosynthesis that is specifically involved in the production of sugars.Which process in the light-independent reactions of photosynthesis is she modeling?

the production of oxygen

the production of glucose

the production of carbon dioxide

the production of water

The Venn diagram compares aerobic respiration and anaerobic respiration.Which statement could be categorized in the overlapping section of the Venn diagram?

uses pyruvic acid

has commercial uses

regenerates NADH

produces 36 ATP

James wants to create a self-sustaining ecosystem, or vivarium. Which method would most likely result in an ecosystem that is viable for the longest amount of time with no additional care?

Put a few plants, water, sand, and a heat lamp inside a clear glass aquarium and seal the top. Place it in a sunny location.

Put water, fertilizer, soil, plants and insects in an open, clear glass aquarium. Place it in an area that has some sunlight and some shade.

Put rocks, water, and many plants in an open, dark-colored plastic tub. Place it in an area with direct sunlight.

Put soil, water, many plants, and a few insects in a sealed, clear plastic aquarium. Place it in an area with indirect sunlight.

How does ATP supply energy for cellular activities?

by breaking off a phosphate group from its structure

by releasing the sugar molecule from its structure

by adding a phosphate group to its structure

by attaching itself to a glucose molecule

A lab experiment to determine the rate of ATP production and its use in plants is conducted. In the lab, twenty circles cut from plant leaves are placed in a container of water with a light source, which allows photosynthesis to occur. When the rate of ATP production exceeds the ATP use, oxygen is given off by the plant cells, causing the leaf circles to float. Using the graph of data from this experiment, at which point was the light source most likely removed?

How does adenosine triphosphate (ATP) become adenosine diphosphate (ADP)?

ATP stores energy as a phosphate bond is formed.

ATP releases energy as a phosphate bond is formed.

ATP releases energy as a phosphate bond is broken.

ATP stores energy as a phosphate bond is broken.

In algae and plants, photosynthesis happens in the

vacuoles.

mitochondria.

chloroplasts.

chromosomes.

Chloroplasts have a complex internal structure, as shown in the model below.In which location is glucose formed?

Location A

Location B

Location C

Location D

Which part of cell division is different in plant and animal cells?

cytokinesis

anaphase

mitosis

eukaryotic

Which statement best describes the overall change that occurs as a result of mitosis?

One cell becomes two cells that have identical copies of DNA.

One cell becomes two cells that have different copies of DNA.

Two cells become two cells that have identical copies of DNA.

Two cells become two cells that have different copies of DNA.

Tissue cultures (samples of cancer cells) are taken from cancer patients, and the cells are then grown in a laboratory. What is the purpose of growing cancer cells in a laboratory?

to test medicinal treatments before giving them to patients

to replace cancer cells with healthy cells

to provide evidence of cancer cells in the patient

to stop the cancer from growing in the patient
