Answer:

C) a transmission electronic microscope

Explanation:

The transmission electron microscope is a high quality instrument to study internal ultrastructure of cells. It uses high energy beam of electrons instead of light for the imaging of the objects. As the wavelength of electrons is less as compared to the light which gives very high resolution of the images. High resolution can be used to analyze ultrastructure of cells.  Thus, the finest details of internal structure of cells can be studied.

The diagram shows the thermohaline circulation, also know as the ocean's conveyor belt.
DanielleElmas [232]

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.

AlekseyPX

Answer:

GUA and GUG.

Explanation:

If you look at the attached genetic code, the wild-type glutamic acid (Glu) is coded by the codons GAA and GAG.

Valine (Val) can be coded by the codons GUU, GUC, GUA or GUG.

Sickle-cell hemoglobin arises from a single mutation, which causes the translation of Val instead of Glu. The only codons that code for Valine that differ in just one base with the Glu codons are GUA and GUG.
