Ecosystem

An ecosystem is a huge association of breathing organisms such as animals, plants, and microorganisms in a particular region. The living and physical elements are joined together through nutrient series and energy progress. Energy enters the ecosystem through photosynthesis and is consolidated into the plant network. By supporting plants and on one-another, creatures play an essential role in the evolution of matter and energy through the system. They also impact the number of plants and microbial biomass present. By decomposing down dead fundamental matter, decomposes and deliver carbon back to the environment and promote nutrient cycling by transforming nutrients stored in stagnant biomass.

<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".

During the human digestion process, digestion is compartmentalized in various organs throughout the digestive system. how does t
GenaCL600 [577]

The human digestion starts in the small intestine gets the most of the nutrients in your food, and your circulatory system passes them on to other parts of your body to store or use.  When food enters the small intestine, villi along the intestine wall along with enzymes help break down the food, and takes a long journey. The stomach is right above the small intestine, and the small intestine is all wrapped around, and isn't that thick. Nutrients from the food are released to the whole body as energy. The small intestine brings the food to the large intestine, which is five feet long and is near your pelvis, or hips. The large intestine connects to the rectum, and then to the anus. In the large intestine, all the water is absorbed as well as salt.

Answer:

if sex cells were identical, there won't be genetics variations and we will just all be identical to our parents. genetic variation allows us to better adapt and survive
