Answer:
See the answer below
Explanation:
Even though plants are rooted in the ground, they still move, exert <u>force,</u> and do<u> work</u>.
Plant cells have very strong cell walls that allow <u>pressure</u> to build up inside of the cell as water is absorbed. This pressure is called <u>turgor</u>.
When turgor pressure is high enough in a cell, the cell walls become <u>firm</u> and as a result, the cell becomes rigid and the plant is able to stand <u>tall</u> and<u> straight</u>.
When a plant does not get enough water, the turgor pressure inside of the cells <u>decreases.</u> A decrease in <u>pressure</u> pushing against the cell wall causes the cells to lose their <u>shape</u> and <u>shrink</u>. This causes the plant to begin to droop or <u>wilt</u>.
When the wilted plant gets enough water, the cells will become rigid again, and the plant will stand firm and straight once again.
Answer:
5010J
Explanation:
The following data were obtained from the question:
Mass (m) = 15g
Heat of fusion (ΔHf) = 334J/g
Heat required (Q) =..?
The heat energy required to melt the ice can be obtained as follow:
Q = m·ΔHf
Q = 15 x 334
Q = 5010J
Therefore, the heat energy required to melt the ice is 5010J.
Answer:The Upper Paleolithic period started about 40,000 years BC and ended about 10,000 years BC. So it took place between 40,000 and 10,000 BC. After that started the Mesolithic Era ( 10,000 to 4,000 BC ). Stone tools in the Upper Paleolithic period were primarly blade-based technology. Also this period is well known for the cave art and paintings of animals. Answer: C ) The period took place between 40,000 and 4,000 BC ( not true ).
Explanation:
Answer:
the ocean, the ocean floor basalts, evaporite deposits and reduced marine sediments.
Explanation:
The answer is B because<span> as </span>plates<span> made of oceanic crust pull apart, a crack in the ocean floor appears. Magma then oozes up from the mantle to fill in the space between the </span>plates<span>, forming a raised ridge called a mid-ocean ridge.
