What causes this periodic change in ocean level
Tom [10]

Answer:Sea levels change for three main reasons: 1) As water warms and cools it expands and contracts; 2) The amount of water contained as ice on land surfaces changes over time; 3) The Earth's surface is dynamic and can move vertically.                                                                                    

Explanation:The first two reasons are directly caused by global temperature changes.

Serga [27]
The correct answer is the fourth option. The magnification of a specimen viewed with a compound light microscope that has an objective power of 10x and an ocular lens power of 5x is equal to 50x. Magnification is equivalent to the product of the objective power and the ocular lens. Ten times five is fifty.

Which statement best describes the relationship of photosynthesis and energy?
Serga [27]

Answer:

A.) The process of photosynthesis is energy-storing because the process converts light energy into chemical energy, which is  stored in the bonds of glucose.

Explanation:

Statement A. best describes the relationship of photosynthesis and energy because this is exactly what the plant does during the process. Plants and some types of bacteria absorb light from the Sun and use it with water (H2O) and carbon dioxide (CO2) to create chemical energy. This energy is then stored in glucose and other molecules. Animals that consume plants will receive this energy.

Hope this helps you :)

Explain two ways materials can enter the cell through passive transport. Include in your answer: the types of substance that is
blsea [12.9K]

Answer:

<em><u>Osmosis and facilitated diffusion</u></em> are two forms of passive transport that are integral to cellular transport mechanisms.

Explanation:

Cells surrounded by a bilipid layer or plasma membrane are amphiphilic, with their polar, hydrophilic lipid heads facing outward, while their hydrophobic non-polar lipid tails facing each other inward.

Although lipid-soluble molecules travel quickly through the bilayer, traveling across its surface into the cell is often difficult for charged and large molecules. Thus, transport proteins, pores and gated channels, transmembrane channels, embedded within the membrane, help to preserve selective permeability.

Across plasma membranes as a form of passive transport in cells, substances move via:

  1. osmosis - water molecules readily pass through the membrane;  the molecules move from high concentration regions to low concentration regions at will through the membrane- they move down their concentration gradient
  2. facilitated diffusion - channel proteins allow charged ions to move across the membrane. Sodium ions are able to pass freely through specialized sodium channel pores into some cells. These channels always remain open- the ions move down their concentration gradient.
