Which of the following is indicated by the size of the minerals in an igneous rock sample?

the size of the mineral crystals in an igneous rock may indicate the rate at which the lava or magma cooled to form a rock.

(larger crystals slow cooling/small quick cooling

Which of the following changes is an example of natural selection?

the percentage of darker beetles increase in population due to larger survival rates to reproduce.

During the N Hemisphere winter, the sun's path across the sky is shorter and closer to the horizon than it is during the summer. This seasonal change in the sun's path across the sky is caused by...

Tilt on Earth's rotational axis

What are the folds of the long digestive system for?

increased surface area which causes greater nutrient absorption.

Chrysalis

cycle= egg, caterpillar, chrysalis, butterfly

Man leaves work and walks to a sandwich shop. He talks with the employee and then walks back to a park bench by his work. Man sits on the park bench to eat his lunch and heads back to work. What graph best reflects his action.

displacement vs. time

Why does the ocean not freeze as fast as a lake?

(Salt water freezes at a lower level temperature. )the answer also has ice crystals in it.

* as ocean water reaches the freezing point, salt crystals interfere with the formation of ice crystals.

What is the biggest danger for the reason of loss of plants and animals?

destruction of habitats

What causes earthquakes or what area are more likely to have earthquakes

areas close to the fault lines/tectonic plates

What type of lightbulb emits energy and heat using electricity

incandescent

What is the missing equation for cellular respiration needed to balance the following chemical equation?

6CO2 (carbon dioxide)6

cellular respiration equation= c6h12o6+ 6co2 + 6h2o + energy

Which of the following is a characteristic for terrestrial planets and not for gas planets?

metal and iron at the core

Effect of current in gulf... humboldt ...?

coriolis force, the coastal aquifers are subjected to the intrusion of seawater.

new question: talked about hot spots in the ocean floor/tectonic plates

volcanos arise from the ocean floor caused by hot spots occurring in the middle of tectonic plates.

Mitosis

cell division in which the nucleus divides into nuclei containing the same number of chromosomes

(answer: 2 sets of 46 chromosomes)

Comet Composition

ice, dust, rock material (dirty snowballs)

water cycle steps

X represents condensation

what direction does rain fall?

slight right in direction (wind)

From the Northern Hemisphere, what place would experience the largest amount of daylight?

Anchorage, Alaska

what statement is true about mutations?

They create variations within genes of population; beneficial for survival.

Compared to the waters of the continental shelf, the surface waters of the open oceans are generally much less productive because they?

lack nutrients derived from the land or ocean sediments on the seabed.

What is the best example of natural selection?

is the process by which organisms with traits that help them survive and reproduce in their environment are more likely to pass those traits onto the next generation.

What causes the winter solstice?

extreme axis tilt away from the sun, shortest period of daylight and longest night

what is produced by photosynthesis?

glucose and oxygen

which best describes the process of photosynthesis?

the process by which plants use sunlight, water, and carbon dioxide to make food (glucose) and release oxygen.

carbon dioxide+water+sunlight --glucose+oxygen

What members of a group act as decomposers?

fungi- living things that breakdown dead organisms and waste, returning nutrients to the environment.

what is inside a nucleus?

protons and neutrons

Question about a little boy making a model of an atom, what would be the most accurate?

nucleus contains protons and neutrons

N Temperature region which marine environment temperature exhibits highest levels of biological productivity?

Estuaries- meeting place river of ocean creating a rich habitat full of life. most productive ecosystem on Earth.

An electrical battery is made with a magnet. The coil is turning because... looking at the images...?

two like poles together

What causes tectonic plates to move?

convection currents in the mantle

heat rises up, cool sinks back down causing movement

What is a good conductor of electricity?

Copper

Students conducting a science experiment with sugar cubes in water vs. crushed sugar in water. Explain rate of dissolvement.

determined by surface area of solute

larger surface area in contact with solute dissolves quicker.

New technology that can detect air pressure

barometer measures atmosphere pressure, which can predict weather conditions

An example of physical weathering is

frost wedging- water freezes in rock cracks and slowly breaks the rock apart.

LOS ANGELES AND COASTAL AQUIFERS. WHAT'S THE MAIN CONCERN OR ISSUE?

subjected to the intrusion of seawater/saltwater

What phenomena is demonstrated during evaporation+

state of water change

What is the problem with deforestation?

Erosion and loss of nutrients.

what affects the ocean tide

The moon/ gravitational pull of the moon

Other option was winds

Parts of a comet

nucleus, coma, dust tail, gas tail

how weather affects leaves release of water??

transpiration- is the evaporation of water from a plant's leaves through tiny openings called stomata.

what is the function of white blood cells in the body?

fight infection

where are earthquakes mostly likely to occur?

boundaries of tectonic plates.

What is the gravitational pull of the moon?

It is the force that attracts objects towards the moon.

What does the gravitational pull of the moon cause?

It causes ocean tides (high and low).

Why does high tide occur on the side of Earth closest to the moon?

Because the gravitational pull of the moon is stronger there, causing water to bulge outward.
