One of the grand challenges in biology is understanding how the first cells formed on Earth. Since all cells are bound by a cell

coldgirl [10]

<h2>Answer is option "A"</h2>

Explanation:

Oils and fats, which in science are called lipids, are known as amphipathic molecules. These molecules have two distinct ends to them: a water-loving (hydrophilic) side and a water-fearing (hydrophobic) side. While the hydrophilic sides of a lipid will associate with the water in a solution, the hydrophobic sides of the lipid all cluster together to 'hide' from the water. Lipids therefore cluster together and form spheres where the hydrophobic sides are in the center away from the water while the hydrophilic sides are on the outside, associating with the water.
The ability of the atoms within a group to form hydrogen bonds with the water molecules around them makes them hydrophilic. Oxygen and nitrogen atoms readily form hydrogen bonds with water molecules, so any organic molecules that have oxygen or nitrogen atoms bound to their carbon skeletons will be hydrophilic.
For example, if we take the molecule for cholesterol, we see the OH group on the left is hydrophilic and will form hydrogen bonds with water, while the ring structures, which only consist of hydrogen and carbon atoms, are hydrophobic and will not associate with the water.
There are many different kinds of lipids with different functions. Lets start by examining phospholipids, which compose the cell membranes of animals. They form lipid bilayers, with one set of hydrophilic heads facing the exterior of the cell membrane and the other set facing the interior (as you can see on the diagram on screen). The hydrophobic portions of the lipid bilayer - the lipid tails - face towards one another, which allows them to hide away from the water inside and outside of the cell.
So,the right answer is option A "amphipathic molecules".

The space shuttle Endeavor is launched to altitude of 500,000 m above the surface of the earth. The shuttle travels at an averag

Marianna [84]

Answer:

Time taken by space shuttle = 714.28 m/s

Explanation:

Given:

Distance cover by space shuttle = 500,000 meter

Speed of space shuttle = 700 m/s

Find:

Time taken by space shuttle

Computation:

Time taken = Distance / Speed

Time taken by space shuttle = Distance cover by space shuttle / Speed of space shuttle

Time taken by space shuttle = 500,000 / 700

Time taken by space shuttle = 714.28 m/s

Zolol [24]

Dispositional traits are personality traits that remain stable and relatively unchanging from about age. They refer to the tendency of an individual to behave in stable and predicted ways. It is similar with the concept of moods. Costa and McCrae believed that personality traits remain the same by the age of 30.
