ressure and temperature conditions?

A.3 kb;800°C

B.5 kb;400°C

C.8 kb;1000°C

D.11 kb;600°C

ng statements would have been most accurate?

A.The fact that the water temperature increased after submerging Resistor B shows that resistor B is a thermistor.

B.The fact that the water temperature increased after submerging Resistor B shows that resistor B is not an ohmic device.

C.Since the measured current was the same when the initial water temperature was 23°C as when it was 25°C,resistor B is an ohmic device.

D.Since the measured current was the same when the initial water temperature was 23°C as when it was 25°C,resistor B is not a thermistor.

Supporters of all three theories would agree that:

A.imprinted genes evolved as a means of regulating reproduction-related events.

B.imprinted genes should be absent in non-placental animals (animals whose offspring develop without a placenta).

C.if an embryo is formed without female-imprinted genes, the future ability of the mother to bear off-spring will be jeopardized.

D.imprinted genes should always be turned off in the mother.

Supporters of the protein control theory believe that:

A.imprinted genes are used to regulate crucial proteins.

B.imprinted genes are active only in females.

C.imprinted genes should not be found in monogamous species (ones that mate for life).

D.only the male passes down imprinted genes to the offspring.

a coarse or super-fine material,which of the following conclusions is best supported by the data?

A.In the deforested area, less sodium was lost during Year 2 than during Year 3.

B.In the deforested area, less sodium was lost during Year 1 than during Year 2.

C.In the undisturbed area, about the same amount of sodium was lost during all three years.

D.In the undisturbed area, less sodium was lost during Year 2 than during Year 3.

With which of the following statements about the conditions on Europa or the evolution of Europa&39;s surface would both Scientist 1 and Scientist 2 most likely agree? The surface of Europa:

A.is being shaped by the movement of ice.

B.is covered with millions of meteorite craters.

C.is the same temperature as the surface of the Arctic Ocean on Earth.

D.has remained unchanged for millions of years.

very smooth with few meteorite craters. Europa&39;s surface ice shows evidence of being continually resmoothed and reshaped. Cracks, dark bands, and pressure ridges (created when water or slush is squeezed up between 2 slabs of ice) are commonly seen in images of the surface. Two scientists express their views as to whether the presence of a deep ocean beneath the surface is responsible for Europa&39;s surface features.

Scientist 1

A deep ocean of liquid water exists on Europa. Jupiter&39;s gravitational field produces tides within Europa that can cause heating of the subsurface to a point where liquid water can exist. The numerous cracks and dark bands in the surface ice closely resemble the appearance of thawing ice covering the polar oceans on Earth. Only a substantial amount of circulating liquid water can crack and rotate such large slabs of ice. The few meteorite craters that exist are shallow and have been smoothed by liquid water that oozed up into the crater from the subsurface and then quickly froze.

Jupiter&39;s magnetic field, sweeping past Europa, would interact with the salty, deep ocean and produce a second magnetic field around Europa. The spacecraft has found evidence of this second magnetic field.

Scientist 2

No deep, liquid water ocean exists on Europa. The heat generated by gravitational tides is quickly lost to space because of Europa&39;s small size, as shown by its very low surface temperature (–160°C). Many of the features on Europa&39;s surface resemble features created by flowing glaciers on Earth. Large amounts of liquid water are not required for the creation of these features. If a thin layer of ice below the surface is much warmer than the surface ice, it may be able to flow and cause cracking and movement of the surface ice. Few meteorite craters are observed because of Europa&39;s very thin atmosphere; surface ice continually sublimes (changes from solid to gas) into this atmosphere, quickly eroding and removing any craters that may have formed.

A.Sublimation;Filled in by water

B.Filled in by water;Sublimation

C.Worn smooth by wind;Sublimation

D.Worn smooth by wind;Filled in by water
