Answer:
A. Radiant energy from the sun, which transforms into chemical energy
Active transport moves substances against the concentration gradient. is a major difference between facilitated diffusion and active transport
<u>Explanation:</u>
One of the comparisons is that both facilitated diffusion and active transport utilize proteins as their medians of moving their materials to and from the cell. Another relationship is the primary purpose of both facilitated diffusion and active transport is to drive material over the cell membrane.
One of the variations is that active transport demands energy, while facilitated diffusion does not require energy. The energy that active transport uses is ATP. The Major difference is that facilitated diffusion enables substances to accompany the concentration gradient either way, while active transport only has substances go one way, against their concentration gradient.
DNA contains Deoxy ribose sugar. RNA contains ribose sugar. The DNA sugar contains one less molecule hence De-oxy.
Answer:
Explanation:
Most limestones actually start as calcium carbonate mud or shells precipitated by organisms in reefs or shallow shelf regions - the biosphere. Over time, the limestone is broken down into its chemical parts and may come back to the surface as volcanic CO2 (in the atmosphere).
<span>. Estuaries have been called the "nurseries of the sea" because the protected environment and abundant food provide an ideal location for fish and shellfish to reproduce. Most commercially important fish species spend some part of their life cycle in estuaries. Besides fish, many species of birds depend on estuaries for food and nesting areas. Migratory birds use estuaries as stopover points for resting and feeding before continuing their journey. Marine mammals also use estuaries as feeding grounds and nurseries.</span>
