Q

Newtons Laws of Motion

A

1st: an object at rest will stay at rest unless an external force acts upon it. An object in motion won’t change its velocity unless an external force acts upon it — law of inertia
2nd: F = Mass x Acceleration
3rd: for every action, there is an equal & opposite reaction

24
Q

What is the second most abundant gas in the atmosphere?

A

Oxygen — represents 21% of the earths atmosphere. Nitrogen is about 78% of the earths atmosphere. The remaining is made up of carbon dioxide, argon, & helium

25
Q

As light passes through a substance, the incident angle changes, meaning the lights entering angle is different than its exiting angle. This is an example of?

A

Refraction — change in direction of light as it passes through a material. Diffraction is wave interference by a medium which causes scattering of the light

26

28
Q

Sound waves will travel the fastest in a medium that is:

A

The most dense

29
Q

Which is the closest to the earths surface and contains the majority of clouds?

A

Troposphere which is immediately above the earths surface — troposphere, stratosphere, mesosphere, & thermosphere — TSMT

30
Q

One of the primary chars of a bacteria is it’s?

A

Lack of a nuclear membrane

A calorie is actually a measure of energy, & is equivalent to how many joules?

A

4.18

32
Q

A nerve impulse is transmitted through your nervous system primarily by?

A

An electric potential

33
Q

The earths surface is covered by approximately what percent water?

A

70%

34
Q

Blood that flows back from the body will enter the heart through the?

A

Right atrium

35
Q

Carbon dioxide can be consumed and converted into glucose by what type of organism?

A

Plants

36
Q

Two separate weather fronts will have air that is if different?

A

Density

37
Q

If one tectonic plate slides under another, the process is known as:?

A

Subduction — when neither plate moves under the other, the result is compression. The two colliding plates will for mountains also known as orogenesis

38
Q

Plants are autotrophs, meaning that they:?

A

Are able to produce their own food — heterotrophs are organisms that must consume other organisms to survive

39
Q

Plant & animals cells both have cell membrane and nuclear membranes. However, plant cells have a structure that animal cells do not, known as a:?

A

Cell wall

40
Q

Muscles in the human body require what energy compound to function?

A

ATP — muscles consume ATP in order to function, which is the primary energy molecule found in the body. ATP can be produced from many sources, but the most common is from glucose

41
Q

When a human cell divides in mitosis, the 2 daughter cells will each have:?

A

46 chromosomes

42
Q

I’m an electromagnetic wave, as the frequency of the wave becomes greater, what becomes shorter?

A

The wavelength

43
Q

Which of the following time periods is the longest?

A

EON — 500 million years
ERA — 100-159 million years
PERIODS & AGES — shorter, 1-10 million years

44
Q

In the lily flower, the red color is dominant & the white color is recessive. This means that if you cross a homozygous red flower with a white one, the offspring will be?

A

All red — if a gene is dominant, then that means the crossing of a homozygous red flower with a white flower will result in all red offspring (who will be heterozygous)

45
Q

Which of the following is a characteristic of the tundra ecological biome?

A

Landscape dominated by shrubs and short trees — tundra environment is characterized by very low year round temperatures, low to moderate rainfall, & shrubs and short trees

46
Q

A solution contains 0.1 molar hydrogen ions (H+). This means the solution is likely:?

A

Around 1.0 pH — if a solution contains hydrogen ions, then it will be acidic, which means low pH. We can calculate the pH = -log(H+)
