it is single-stranded
it is used to make proteins
it contains uracil
all of the above
A scientist has just finished collecting data on the feeding habits of a certain species of ant.
Which parts of a scientific process should the scientist undertake next?
The scientist should make conclusions.
The scientist should form a hypothesis.
The scientist should communicate the results.
The scientist should analyze the data.
Shortly after a chimpanzee embryo begins growing, its cells begin to look different.
Which statement best describes what is happening at this point in the chimpanzee embryo's development?
Mitosis is making identical new cells from the original cells.
Differentiation is taking place to create cells with specialized functions.
Meiosis is making many different types of cells.
Cellular respiration is breaking down old cells to form new ones.
Which statement is true about the cells in multicell organisms?
They can all turn into the same kind of cell if needed.
They are all identical.
They are prokaryotic cells.
They usually have certain special functions.
The cell membrane is made of phospholipids and is selectively permeable, or semipermeable.
Which major theme in biology does this statement represent?
DNA transcribes into RNA, and RNA translates into proteins.
All living things require an energy source.
Structure relates to function.
All organisms share seven basic characteristics.
One characteristic that living things share is metabolism.
Which statement best describes metabolism?
Metabolism is the balance an organism maintains between building up and breaking down substances in its cells.
Metabolism is all of the components an organism needs to survive.
Metabolism is the different kinds of energy a cell uses to function.
Metabolism is the sum of all of the internal systems in an organism.
The organic compounds in living things are organized into groups: carbohydrates, lipids, proteins, and nucleic acids.
Which two compounds do living things most commonly use as an energy source?
carbohydrates and lipids
lipids and nucleic acids
proteins and nucleic acids
proteins and carbohydrates
Which statement explains Mendel's law of segregation?
Two alleles that were segregated come together during meiosis.
Two alleles for a trait separate during meiosis.
Alleles of the same trait segregate only during mitosis.
Alleles of a trait can never be separated from each other.
Which statement about energy is true for all living things?
Energy comes only from sunlight.
Organisms require energy for survival.
Energy cannot transfer from one organism to the next.
Plants convert energy into ATP.
Which statement describes the manner in which an herbivore, such as a deer, gets and uses energy?
It eats plants and converts the sugar in plants into ATP
by cellular respiration.
It uses photosynthesis to convert the glucose in plants into ATP.
It changes plants into ATP through protein synthesis.
It seeks out plants that contain chloroplasts to make ATP.
Which statement describes the relationship between a gene and an allele?
A gene is made of small parts called alleles.
A gene can take different forms called alleles.
Many genes put together are called an allele.
Alleles are similar genes from different species of organisms.
A lion's body cells perform many tasks at once; for example, some cells are involved in growing new claws and some cells help the lion keep breathing.
Which statement tells the most important factor that allows cells to keep accomplishing their many tasks?
Cells are constantly producing usable energy in the form of ATP.
DNA is transcribing into RNA, and RNA is translating into proteins.
New cells are continuously being made from old ones in the process of meiosis.
Cells contain DNA from two individuals, and the combined DNA is constantly resulting in genetic variation.
Which statement is true about the types of chemical elements in living cells?
Animal cells and plant cells contain very different elements.
Single-cell organisms have different types of elements from multicell organisms.
All cells contain the same key elements, such as carbon, nitrogen, and oxygen.
Very few cells contain either carbon or oxygen.
Which of these word formulas for cellular respiration is correct?
Oxygen + Sugar → Energy + Carbon dioxide + Water
Carbon + Sugar → Energy + Carbon dioxide + Water
Nitrogen + Sugar → Energy + Carbon dioxide + Water
Hydrogen + Sugar → Energy + Carbon dioxide + Water
Select the correct formula for photosynthesis.
Which of these is unlikely to happen during the process of sugar breakdown in a cell?
The starting materials in the process are glucose (sugar) and oxygen.
Carbon dioxide formed is used by the cell for various activities.
The products formed are carbon dioxide, water, and energy.
Energy is released and is used for cell’s life functions.
Which process results in two daughter cells each having the same number of chromosomes as the parent cell?
cytokinesis
meiosis
mitosis
photosynthesis
Among a species of butterflies, the color blue (B) is a dominant trait. Yellow color (b) is a recessive trait. If a pure blue butterfly (BB) mates with a pure yellow (bb), what will the offspring look like?
They will all be blue.
About 75% will be blue and 25% will be yellow.
They will all be yellow.
Half will be blue and half will be yellow.
Our traits are determined by our genes and these traits are inherited. Where do our genes come from?
our father
our mother
from both parents equally
part from our mother but mostly from our father
A couple is expecting their first child. Both parents have O blood type. What are the possible blood types for their child?
O only
A, B, AB or O
A & B
AB only
