In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure.
Chromosomes are not visible in the cell’s nucleus—not even under a microscope—when the cell is not dividing. However, the DNA that makes up chromosomes becomes more tightly packed during cell division and is then visible under a microscope. Most of what researchers know about chromosomes was learned by observing chromosomes during cell division.
Answer:
The statement that is true about red currents in the thermohaline circulation is that water in the red currents contain less salt (option A).
Explanation:
Thermohaline circulation is a concept used in oceanography, referring to the oceanic circulation that depends on factors such as surface heat and salinity, as well as the density gradient that they determine.
On a map, the different currents that are part of the thermohaline circulation are usually represented with blue and red lines, where:
- <em>The blue lines represent deep, cold, dense and higher salinity currents.</em>
- <em>The red lines represent surface currents, warm, with less salt content, so they are less dense.</em>
The red currents (see image) represented on the map have less salt content, compared to the currents represented in blue.
