What must DNA be able to do in order to successfully replicate?
Break down the sugar-phosphate backbone
Complementary pair the nitrogenous bases
Twist into a double helix
Add additional phosphate groups to the nucleotide
In 2010, scientists excavated a skull fossil that provides evidence of a newly discovered species of big cat. Based on the evidence, scientists hypothesize that big cats branched off from smaller wild cats about 6 million years ago. Which of these resources did the scientists most likely rely on to form their hypothesis?
A food web showing feeding relationships of organisms where the fossil skull was found
Population and migration data for small wild cats living in the ecosystem where the skull was found
The fossil record and deoxyribonucleic acid comparisons of big cats and small cats
The historical accounts and records of interactions between different species of big cats
Which statement describes how the function of lipids and carbohydrates are similar?
Both provide the body with energy.
Both speed up the rate of reactions.
Both contain peptide bonds and amino acids.
Both are used to store genetic material.
Long necks in giraffes are an example of a trait that has been naturally selected over the evolutionary history of an organism. Which of the following best explains what must have happened for this selection to occur?
In each generation of giraffes, there was an abundance of resources available for each individual.
In each generation of giraffes, long-necked giraffes mated only with short-necked giraffes.
In each generation of giraffes, there was variation in neck lengths, and scarcity of resources meant that not all giraffes survived.
In each generation of giraffes, all the neck lengths were the same, and all the long-necked generations survived.
Which cellular process takes place in the ribosomes that are bound to the endoplasmic reticulum?
The breakdown of waste material
The conversion of radiant energy to glucose
The synthesis of new proteins
The replication of nucleic acids
A virus causes an illness that includes the following symptoms: headaches, fever, and body aches. Symptoms usually occur two to seven days after infection by the virus. The type of reproductive cycle this virus most likely has is —
Lysogenic, because the virus is a coronavirus
Lytic, because the virus causes respiratory illness
Lysogenic, because the virus primarily affects older people
Lytic, because of the quick onset of symptoms after infection
When cells leave the cell cycle, they exit during G1 phase and then enter G0 phase, a resting period. Most normal cells can leave G0 phase and reenter the cell cycle at G1 phase before entering S phase. Cancer cells are different because they cannot enter G0 phase and are likely to do which of the following?
Fail to complete S phase
Mutate during G1 phase
Repeat the cell cycle continuously
Die after completing mitosis
What is lost to the environment at each of the trophic levels of this ecosystem?
Nutrients from the soil
Living space for the organisms
Food sources
Heat
Pepsin and trypsin are two of the digestive enzymes that break down protein. A group of students studied the pH requirements of these enzymes. The graph shows the results.
The students found that pepsin functions best in an acid environment and trypsin functions best in a neutral environment. Based on their observations, pepsin most likely aids in digestion in which part of the human body?
Pancreas
Intestines
Mouth
Stomach
Which of the following functions at the same organizational level as the kidney in the human excretory system?
Skeleton
Epithelial tissue
Urinary bladder
A squamous cell
