Answer: 45 J

Explanation:

The formula for work is force x distance.

W = fd

W = (30 N)(1.5 m)

W = 45 J

Answer:

ATP and NADPH are used to energy for the production of the Calvin cycle. Once their energy is released, they revert back to ADP and NADP+ and can be reused again.

Explanation:

ATP and NADPH are energy carriers that can be used to power chemical reactions. Once they have energized cellular processes, they become their 'low energy' form of ADP and NADP+. Later, they can reform ATP and NADPH to power more reactions

Dafna11 [192]

Which of the following statements is false? The inflammatory response can occur on the surface of the body and internally. Phagocytes are responsible for much of the healing that occurs with inflammation. Platelets release a growth factor that stimulates endothelial cells to divide, and the wound heals. Pus is produced during an inflammatory response that is inappropriately strong. Mast cells release propagandist, which are partly responsible for the pain of inflammation.

It's B

<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".
