Active transport requires energy and moves materials from a place of low concentration to a place of higher concentration. Passive transport does not require energy and moves material from high concentration to lower concentration.

Well first you need to know that passive transport moves molecules with the <span>concentration gradient </span> which is high to low, while the active transport moves molecules against the <span>concentration gradient which is low to high. Also,</span> passive transport<span> doesn't require energy which is ATP, while </span>active transport<span> does require energy.

Hoped I helped! I LOVE biology so if you need any help with cells, human systems, etc I'm your gal! :) </span>

Philippe wants to measure how much water his potted tomato plants lose through transpiration each day. To do this, he sets up a
raketka [301]

1. The correct answer is B.

Blatantly increasing or decreasing the rate of transpiration is not an accurate way to measure the typical amount of water that is lost through transpiration, which eliminates choices C and D. The method proposed in choice B is pretty wrong and will lead to the collection of no water.

For the second question, the correct answer is A. The prompt mentioned that the dirt area contained the most water, which automatically eliminates choices B and D. What makes choice C wrong is that the water reached the materials in equal amounts, but some of them were able to infiltrate the water faster. Hard-packed dirt will, due to its thickness, always take the longest to infiltrate water.

For the third question, we know that energy is required to melt things -- thus eliminating choices B and D. Because the energy is being used, it would have to lose some energy and not gain any back unless you're melting something. The difference between choices A and C is that HEAT is released during crystallization...only! In order for something to melt, heat/energy must be taken in. So, the correct answer is C.

Mafic lava tends to have low silica content. Based on this, which of the following statements about mafic lava is most likely tr
VLD [36.1K]

Answer: A. It contains fewer volatile gases

Explanation:The mafic lava is a lava type that has low viscosity. The reason for that is its composition, being very rich in magnesium and iron. Because this type of lava is low in viscosity, it is unable to contain the majority of the gases and water in it, as they find it relatively easy to ''escape'' from it. That results in much calmer eruptions of the volcanoes that produce mafic magma, with explosions almost never occurring, and even if they do they are very small.

hope this helps
