The question is <u>incomplete,</u> options are given below:
A. A tropical area with moderate rainfall
B. A temperate forest
C. A steep slope
D. A river delta
Answer:
<em>C.</em><em> A steep slope</em>
Explanation:
Erosion is a <u>weathering process</u> that causes removal of the top layer of sediments from any geological material (rock, plain area, etc) and then transports that material to another place. This process is governed by the combined action of wind, water (precipitation), gravity, and other meteorological parameters.
For this question, four options are given among which rate of erosion would be faster than the rate of soil formation for a steep slope. For a steep slope, the movement of water and wind would be stronger along with high gravitational pull as compared to the tropical area, river delta, and temperate forest. In principle, in the temperate forest, the erosion would be lowest due to the presence of plant roots that support the soil material to stay aggregated and resist against weathering.
Answer:
The correct answer is: C. Active Transport.
Explanation:
Because Na+ and K+ are ions, which makes them <em>charged molecules</em>, they can only diffuse through the cell membrane when using specialized protein channels. This is called <u>facilitated diffusion</u> and is a form of passive transport because sodium and potassium move <em>following their gradients</em>, which are made of the difference in concentration between the inside of the cell and the outside of the cell. For example, potassium is highly concentrated inside the cell and poorly concentrated outside the cell, so potassium diffuses from the inside to the outside to even the concentrations.
But the question asks in which process Na+ and K+ move in and out of the cell SIMULTANEOUSLY, so the answer is actually <u>active transport</u>. Active transport is the opposite of passive transport. While passive transport occurs naturally and doesn't need ATP (energy) to happen, active transport needs ATP because it moves molecules AGAINST their gradient. One of the most famous and important structures involved in active transport is the Na+/K+ pump, which consists of a <em>specialized protein using energy to enter 2 potassium ions and take out 3 sodium ions at the same time</em>. This Na+/K+ is fundamental to maintain the gradients, which are important for the correct functioning of many cells.

Answer:
Transcribing DNA into mRNA
Explanation:
The geneome of most DNA-containing viruses that infect eukaryotic cells is transported in the cell nucleus, where the cellular DNA is, of course, also found. Once inside the cell, the viral DNA interacts.
(Hope this helps!!)
Technically A and B, but A is more true, so it is the 'correct' answer.
