Which type of molecule is not found in the membrane of an animal cell?

Phospholipids, protein, and cholesterol are all found in animal cells. Cellulose, however, is only found in plant cells.

In a given strand of DNA, which combinations of base pairs are observed?

A purine pairs with a pyrimidines. The purine guanine is the complement of the pyrimidine cytosine; and the purine adenine is the complement of the pyrimidine thymine in DNA. Uracil pairs only with adenine in RNA.

A change in the membrane potential of a neuron from -70 millivolts to +50 millivolts is called...

Most cells maintain a membrane potential in which the internal environment is negatively charged compared to the environment. Depolarization allows for the transmission of electrical impulses and is a form of communication within and between cells.

What aspect of water makes it so crucial to life on earth?

A dipole molecule is electrically neutral and has a positive and a negative charge which helps many substances dissolve and therefore promotes interactions among them.

Which of the following is a statement of the first law of thermodynamics?

Energy can be transformed, but not created or destroyed.

Which of the following do not require membrane proteins for transport?

Hydrocarbons are hydrophobic and can therefore easily cross the cell membrane by diffusion (passive transport).

When the pH of a solution shifts from 7 to 3, how has the hydrogen ion concentration changed?

pH is a logarithmic function, so a change in one unit (for example, from 7 to 6) indicates a 10-fold change in the hydrogen ion concentration. Therefore, decreasing from 7 to 3 indicates a 10,000-fold increase in hydrogen ions.

Where do the enzymatic reactions of the Calvin cycle take place?

The stroma is the inner space of the chloroplasts.

Which condition would cause increases in the rate of photorespiration?

Photorespiration is an enzymatic reaction that uses oxygen, produces carbon dioxide, does not generate ATP, and is not coupled to any electron transfer system.

Macrophages are a type of white blood cell that can take up bacteria and viruses in order to destroy them and protect the surrounding cells. Which of the following aids the macrophage in this process?

Lysosomes are membrane-bound organelles that contain enzymes for degrading damaged organelles.

Which of the following is beneficial to a paramecium that has evolved to live in a pond?

Contractile vacuoles help balance the ion and molecule concentrations by pumping extra water out of the cell.

Under anaerobic conditions (for example in the process of making wine), yeast will ferment sugars to produce:

Fermentation is a process that occurs in yeast, bacteria, and muscle cells that converts sugar to acids, gases, or alcohol.

What feature of the carbon atom makes it ideal as the foundation of most biological molecules?

The four electrons available in carbon enables chemical bonding and interactions with many other elements.

Which of these subatomic particles forms the basis for interactions between atoms?

Electrons are shared and/or exchanged to form chemical bonds.

The pH of a system is defined by which of these factors?

The pH scale measures how acidic or basic a substance is, and ranges from 0 to 14, where 7 is neutral, above 7 is basic, and below 7 is acidic.

In an aqueous solution, most of the hydrophobic sidechains of amino acids of a protein orient in what way?

Many hydrophobic sidechains form the “hydrophobic core” of the protein, driven by repulsive forces from the aqueous environment.

An electron shell represents:

Electrons clouds are based purely on mathematical probability of an electron being in a particular location, which forms an image of an orbit.

An egg can develop without fertilization. What is this process called?

Parthenogenesis can be a normal process in some invertebrates and lower plants.

When do red blood cells undergo mitosis?

Mature red blood cells have an average life span of 120 days, and do not undergo mitosis because they do not have a nucleus, whereas other cells types including skin and hair cells can divide through mitosis.

If a person is heterozygous (has both a dominant and recessive allele) for a particular gene "v", what is their genotype?

If an organism has two different alleles of a gene, it is heterozygous. If it had two of the same allele, it would be homozygous.

Why do the leaves on deciduous trees change colors from green to reds, oranges, and yellows in the fall?

When nights get longer, chlorophyll levels decrease, and this allows us to see the other pigments (red, orange, yellow) that were hidden by the green.

When electrons move through the electron transport chain, their energy helps to:

The electron transport chain builds up a surplus of hydrogen ions that flow as free energy to help generate ATP.

In which process is one molecule of glucose broken down into two molecules of pyruvate?

The process of glycolysis is one step in the process of cellular respiration that allows the simple sugar glucose (coming from your food), to be broken down into energy that you can use.

Which of the following RNA strands is synthesized from the DNA strand ACCGATATG?

RNA nucleotide pairs do not contain the Thymine (T) nitrogenous base - it is replaced with Uracil (U).

What is a community of plants and animals with similar characteristics that occupies a specific region?

Five major types of biomes are: aquatic, desert, forest, grassland, and tundra.

What type of biome receives the least amount of yearly rainfall?

The average annual rainfall in a desert is generally less than 7 inches.

What type of biome has a mild summer, leaves that fall off the trees in autumn, and a cold winter?

Temperate zones generally have distinct seasons of warm and cold, and have deciduous trees that lose their leaves in autumn.

From one molecule of glucose, what is the net total ATP production of glycolysis, the Kreb's cycle and oxidative phosphorylation?

The breakdown of ATP produced during cellular respiration is: 2 from glycolysis, 2 from the Krebs cycle, and about 34 from the electron transport chain.

What are the different levels of the food chain called?

The trophic levels are groups in which organisms share the same function in the food chain and have the same nutritional relationship to primary sources of energy. The origin of the word "trophic" is from the Greek word that refers to food.

Which of the following can eat at more than one level of the food chain?

Omnivores are primary and secondary consumers because they can eat both plants and animals .

What is a non-mutual symbiotic relationship between species, where one species benefits at the expense of the other?

For example, a tapeworm (parasite) that lives in the intestines of a mammal (host) benefits from the nutrients intended for the mammal, causing harm to the mammal.

What is the name of the process by which glucose is synthesized from other carbon-containing molecules?

The most common carbon molecules used to produce glucose in the reverse process of glycolysis are: pyruvate, lactate, glycerol, and the amino acids alanine and glutamine. The liver is the major site of gluconeogenesis,

Water from waste products of digestion is absorbed by the _____________.

Water and some nutrients are reabsorbed in the large intestine, and the the waste products are compacted to prepare for elimination from the body.

The study of changes in organisms as a result of modified gene expression as opposed to alterating the genetic code is called:

Research has shown that external and environmental factors can affect gene expression to cause changes that may or may not be heritable.

Which of the following would NOT be considered a renewable resource?

Fresh water, solar energy, and timber are all renewable resources since they can be used repeatedly because they are replaced naturally.
