Why would cells need to move things in and out?

Answer:

Cells do not generally allow such materials to go in because they are having a cell membrane outside. The cell membrane only allows the materials which are required for the growth of the cell such as water and minerals.

Volcanic eruptions and emissions from vegetation are the natural causes of which phenomenon
SSSSS [86.1K]

Answer: Acid rain

The volcanic eruption is a natural phenomena that results in the liberation of the lava from the heap of the earth along with the gases. The volcanic eruption causes major damages to the vegetation lying above the erupted crater of the volcano. This results in the immense release of gases such as carbon dioxide, carbon monoxide, sulfur dioxide, hydrogen chloride, hydrogen fluoride, methane and ammonia all these gases are major pollutants of the air. These gases reacts with water vapor in the atmosphere and condense in the form of acid rain.

im on a timed test in online schooling and nobody will help me,the question is: The driving force behind the water cycle and how
Yuliya22 [10]

Explanation:

<h2>It is interesting to note that CO2 is still believed to be the No 1 greenhouse gas instead of water vapour. Many excellent climate scientist (e.g. Richard Lindzen, Roy Spencer, John Christy, etc) have dealt with the issue and shown both in books and research articles that CO2 is a very minor player governing global climate.</h2><h2>So what drives climate?</h2><h2>The answer must obviously be found in the hydrological cycle, where the oceans play a major role together with extraterrestrial process with the Sun having the ultimate role. We know that solar energy (insolation) does not vary sufficiently to explain the climatic excursion our planet has experienced on a short and long term. It is sufficient to consider the Little Ice Age and the Medieval Warm Period, not mentioning the past ice ages, to understand that there are many complicated factors to consider before we can explain climate variability.</h2><h2>Solar activity is naturally a major player but this does not mean only total solar insolation (TSI) but also solar magnetic activity. Also the gravitational influence of the entire solar system must be taken in account, not forgetting our own natural satellite, the Moon, influencing at least ocean tides. Very interesting views on climate variability and cosmic activity have been presented by Henrik Svensmark.</h2><h2>A very simplistic example how the water cycle could adjust climate is the following mental construct: The Sun warms the ocean surface increasing evaporation. Increase in water vapour content decreases the density of the air, which thus rises to higher altitudes where eventually adiabatic cooling reaches a level where water vapour starts to condense. The availability of condensation nuclei, possibly enhanced by high energy cosmic radiation especially during low level solar magnetic activity, leads to strong cloud formation. This eventually limits solar warming of the ocean surface and decreases evaporation with less cloud formation. This entire cycle can be compared to a very effective thermostat, by some aptly termed the water thermostat responsible for keeping global temperatures at a suitable level depending on local conditions</h2>

Some helpful tips:

The nucleus is always going to be the big, spherical shape.

The ER is always going to be a weird, folded looking structure attached to the nucleus (rough = has ribosomes on it which are usually represented by little dots, smooth = has no ribosomes on it aka no dots)

The GA looks like the ER but it is not going to be attached to the nucleus like the ER is.

The mitochondria is always going to be pill-shaped and have weird folds inside of it.
