Back 53

neutrons and protons (electrons are a cloud surrounding the nucleus)

Front 54

Why does the human eye perceive a red colored dress as the color red

Back 54

We see a red dress as “red” because those wavelengths are reflected and not absorbed.

Front 55

s. In general, the higher the trophic level of the consumer, the less overall available energy. Primary consumers have more energy available than both secondary and tertiary consumers.

Trophic level info

Front 56

In a lab experiment designed to test the rate at which plants grow under artificial light, the kind of light used is which type of variable?

Back 56

In an experiment, an “independent variable” is a factor controlled by the scientists. A "dependent variable" represents the output or effect. Since the light is controlled by the experimenters, it is an independent variable.

Front 57

Which organ system is primarily responsible for regulating metabolism, mood, and growth?

Back 57

Endocrine

Front 58

In a vacuum, why doesn’t an elephant accelerate faster than a penny as it falls to the ground?

Back 58

More massive objects will only free-fall faster than smaller objects if there is a significant amount of air resistance present. For a penny and an elephant that are free-falling in a vacuum, the rate of acceleration would be the same, so both would fall at the acceleration due to gravity which is 9.8m/s2.

A scientist found that when an invasive species was introduced into a river, the population of salmon native to the region decreased. The type of correlation between these two populations could best be described as

Back 59

When one factor affects a second factor, it can be said that the two have a strong correlation. Since the salmon population decreases as the invasive species population increases, these two factors have an inverse relationship.

Front 60

The pharynx is part of what body system

Back 60

The pharynx is part of two systems; the respiratory and the digestive. It is another name for the throat, which extends from the base of the skull to the level of the sixth cervical vertebra.

Front 61

What characteristic of an element determines its specific isotope

Back 61

The number of neutrons is what gives the element its specific isotope. The number of protons determines which element it is, while the number of electrons determines if the atomic particle has a positive, negative, or neutral charge.

Front 66

In plants, ________ involves the formation of a _____?

Back 66

Cytokinesis happens after telophase and it is the splitting of one cell into two. In plants it involves the formation of a cell plate whereas in animals it involves the formation of a cleavage furrow.

Mitosis in plant

Back 68

Front 69

Which base is NOT found in DNA?

Back 69

Uracil. The information in DNA is stored as four nucleotides: adenine (A), guanine (G), cytosine (C), and thymine (T). RNA replaces thymine with uracil (U)

Front 70

How do you calculate atomic mass?

Back 70

To calculate the atomic mass, we must sum the number of protons and the number of neutrons inside of the nucleus.So, adding 42 protons with 37 neutrons results in an atomic mass of 79.

Front 71

Site of memory storage

Back 71

Hippocampus

Front 72

In which process is there two steps that result in four daughter cells with half the DNA from each parent cell?

Back 72

Meiosis

Front 73

Is power equal to energy divided by time?

Back 73

Yes

Front 74

What type of cells result from mitosis

Back 74

Mitosis produces two diploid daughter cells that have the same genetic material as the original mother cell.

Front 75

Cheetahs, rainbow trout, and inchworms belong to the same

Back 75

All three animals belong to the same kingdom of Animalia, but are too different to be classed in the same phylum. Cheetahs and rainbow trout are in the Chordata phylum, while inchworms are in Arthropoda phylum.

Front 76

Does ANP cause increase or decrease of water retention

Back 76

Atrial Natiuretic Peptide is a hormone released in response to increased blood volume and pressure that produces vasodilation. As a consequence of this vasodilation, the excretion of both sodium and water increases in order to return to the homeostatic conditions prior to increased blood volume and pressure. Because excretion of water increases, ANP causes a decrease in water retention and not an increase.
