Cells require glucose as a source of energy to carry out life processes. Large molecules like glucose cross the cell's plasma membrane byA)
being pumped through ion channels.
B)
active transport through protein channels.
C)
passive diffusion through the lipid bilayer.
D)
facilitated diffusion through protein channels.

Answers

Answer 1

Answer: Answer – D. Facilitated diffusion through protein channels
Glucose molecules are too big to pass through the plasma membrane by direct diffusion, so Glucose gains entrance into a cell by facilitated diffusion through protein channels in the plasma membrane. Since glucose moves with the concentration gradient, the built-in protein channels are only there to facilitate the movement of glucose into the cell and no energy is expended.

Answer 2

Answer:

proteins are used to help move molecules more quickly. It is a process called facilitated diffusion. It could be as simple as bringing in a glucose molecule. Since the cell membrane will not allow glucose to cross by diffusion, helpers are needed. so the the correct chioice is D

The formation of the Canary Islands was primarily caused by their location near a ?1) subduction zone
2) mantle hot spot
3) divergent boundary
4) transform fault

Answers

The formation of the canary islands was primarily due to their location near a mantle hotspot.

Most modern forms of transportation are powered by fossil fuels. Carbon dioxide, methane, carbon monoxide, and other gases are released into the atmosphere during the production and combustion of these fuels. How might these gases cause climatic changes? These gases have no effect on atmospheric temperatures, so they are unable to cause any type of climatic changes. These gases cause more water vapor to condense, making climates wetter than they were in the past. These gases reduce the amount of thermal energy escaping into space, effectively warming the atmosphere.

Answers

The correct answer is the last option.

The first option (unable to cause climate change) is incorrect because these gases do effect the atmospheric temperatures by increasing them.
The second option is incorrect because while these gases do cause more water vapor to condense, they result in acid rain (not wetter climates).

Greenhouse gases, such as carbon dioxide, methane, and water vapor, are released into the atmosphere in large quantities during the production and combustion of fossil fuels. These gases help to reduce the amount of thermal energy escaping into space, effectively warming the atmosphere.

What type of crustal collision led to the formation of the Andes Mountains? A. oceanic crust to oceanic crust collision B. oceanic crust to continental crust collision C. mantle to core collision D. continental crust to mantle collision

Answers

Oceanic crust to continental crust collision led to the formation of the Andes Mountains. Therefore, the correct option is B.

The collision between the oceanic Nazca Plate and the continental South American Plate was the primary reason for the development of the Andes Mountains. The collision of oceanic crust with continental crust occurs when oceanic crust subducts under continental crust. The subduction of oceanic crust beneath continental crust resulted in the uplift and formation of the Andes Mountains through volcanic activity and crustal deformation.

Therefore, the correct option is B.
