Answer:

lipid

Explanation:

lipids form phospholipid bilayers which are the largest portion of the cell membrane and contain a hydrophobic (insoluble in water) end made up of two fatty acid chains of nonpolar molecules such as carbons and hydrogens. The other end is hydrophilic (soluble in water) and contains polar phosphate molecules.

Human beings are responsible for the loss of forest. Why?​
Blababa [14]

Beause we cut down a lot of trees. Often, so many, that the health of a forest is irreparably damaged. A forest is not just a bunch of trees. It is a whole ecosystem, in which the trees anchor the growth of many other plant and animal species, hold the ground together to prevent erosion, and produce a lot of oxygen to support animal life. If you harvest too many of the trees, the local ecosystem stops being a forest and starts turning into something else

garik1379 [7]

Answer:

Southern Texas

Explanation:

The Wind pattern often is represented by the westerlies, which are the winds that flow in the northern latitude of the world. The humidity level in this zone varies from 10-20%, since we are in the desert we do not have much humidity, the solar intensity is high, often found in the 9-10 uv range, it is not advised to spend more than 10 minutes on direct sun without solar protection.  We have the Rio Grande to the south and some spare mountains.

Complete the complementary strand of DNA, using the same symbols for phosphates (circles), sugars (pentagons), and bases. Mark t
OleMash [197]

About the question:

You will find the completed strand in the attached files

Answer and Explanation:

First, we need to recognize each strand, the original one and the complementary one. We can recognize the original strand because bases are already given. So,

  • The original strand is the one at the left,
  • The complementary strand is the one at the right.

Now we need to recognize and pair the bases. Names are written with their letters.

Nitrogenated bases that form nucleic acids correspond to purines and pyrimidines. Adenine and guanine derive from purines, while Thymine and Citocine derive from Pyrimidines.  

In the DNA molecule, Adenine (Purine) forms pairs with Timine (Pyrimidine), while Guanine (Purin) pairs with Cytosine. Two hydrogen bonds join the A-T pair, and three hydrogen bonds join the G-C.

Once we drag the base labels to their targets, we need to recognize each of the strain extremes.

One of the extremes has a phosphate group, which is named 5´. The other extreme has a hydroxyl OH named 3´. Both of them are readen in the 5´to 3´ direction. The polymerase enzyme reads the original strand in 5´ to 3´ mode, and the molecule lecture goes from 3´to 5´.

So, by looking at the labels, we will recognize the phosphate extreme and the hydroxyl one. We will place in the superior extreme of the original strain the phosphate group 5´ and in the other extreme the OH 3´. These positions will give us the direction reflected by the arrow. The complementary strand will have the same extreme labels but in opposite places. So first we will place the OH 3´ label in the superior extreme, and the phosphate 5´label in the inferior extreme, defining the direction reflected by the arrow.
