I believe the correct answer is true. Veins are often formed from hot water solutions. Hydrothermal deposits are a very common method of filling already existing fractures and occurs at varying depths. T<span>here are lots of veins formed by hot water that cause fractures or work their way up into non fractured rock. </span>

D = m/v
1) 10*9*6 = 540 cm3 (volume of bar)
2) 873/540 = 1.62 g/cm3
The answer is A)
Carbon enters the atmosphere as carbon dioxide from respiration and combustion. Carbon dioxide is absorbed by producers to make carbohydrates in photosynthesis. Animals feed on the plant passing the carbon compounds along the food chain. ... The animals and plants eventually die.
Answer:
Passive transport involves movement of substances from areas of higher concentration to areas of lower concentration.
Explanation:
Passive transport involves the passage of substances through a semi-permeable membrane, as occurs with transport at the level of cell membranes.
Generally, passive transport occurs with the <u>movement of compounds from the space with the highest concentration of a specific substance to the space with the lowest concentration of the same substance</u>, following the so-called concentration gradient. Theoretically, the gradient tends to disappear when the concentrations of substances have balanced out.
Regarding other options:
<em> A. </em><u><em>From areas of lower concentration to areas of higher concentration</em></u><em>. It is a feature of active transport.</em>
<em> C. </em><u><em>From areas in which the concentration has reached a balance</em></u><em>. There is no passive transport</em>
<em> D. </em><u><em>From areas of differing concentrations with the use of cellular energy</em></u><em>. Energy use involves active transport.</em>
