4. Which of the following methods of soil conservation uses the roots of plants as anchors in the soil?
<span>Planting trees on sloped surfaces.
In this way, soil erosion is minimized as well as the amount of water run off.
5. </span><span>Which of the following soil components results from the breakdown of parent material?
</span><span>Minerals</span>
In humans, new neurons are continually born
throughout adulthood in two regions of the brain:
<span>·
</span><span>The subgranular
zone (SGZ), part of the dentate gyrus of
the hippocampus.</span>
<span>·
</span><span>The striatum;
however the adult-born neurons are a type of interneuron,
not a type that projects to other brain areas.</span>[5]
<span>In other species of mammals, particularly rodents,
adult-born neurons also appear in the olfactory
bulb. In humans, however, few if any olfactory bulb neurons are
generated after birth.</span>

Answer:
Prokayotes may be defined as the organisms that lacks the nucleus and the membrane bound cell organelle. Eukaryotes have the well defined nucleus and contains the membrane bound cell organelle.
The evolutionary advantage that has been noticed in the eukaryotic cells is the compartmentalization of the cell. The cell compartmentalization separates the cell organelle into the specialized functions. This division of labor increases the efficiency of the cell and regulates the evolution of the complex multi cellular organism.
Answer: All membrane lipids are amphipathic
Explanation:
The membrane lipid molecules are amphathic in nature which states that they are both hydrophobic and hydrophillic part. The lipid bi layer has been found tot be the most widely found in cell structure.
The structure is made of phosphorus and lipids and hence called as phospholipids.
The amphipathic nature of the lipids allows it to assemble spontaneously into bi layers even under the artificial conditions.
hence, all the lipids in the cell membrane or membranes are amphipathic in nature.
