I would say immigration only.
emigration would theoretically reduce the genetic variation as unique individuals leave, but immigration would bring unique traits into circulation in an ecosystem.
I'm not super great at biogy tho so this might not be right... :)
Answer:
(a) can be used to bend epithelial sheets into tubes.
Explanation:
The adherens junctions are cell-cell adhesions localized in places exposed to abrasion or mechanical stress, close to the apical membrane in epithelial cells is one of these locations. Some of their functions are the initiation and stabilization of cell-cell adhesion, <em>they join the actin cytoskeleton to the plasma membrane to form adhesive contacts between cells that contribute to the folding and bending of epithelial sheets,</em> therefore they can mediate adhesion and signaling.
I hope you find this information useful and interesting! Good luck!
Answer
Species with lower resilience have less chance to survive.
Explanation
The resilience rate means to recover after destruction. The species having a higher rate of resilience recover fast when undergoing any damage hence have higher chance to survive. The species with lower resilience rate can collapse as a result of any damage to species by any internal factor such as disease or external factors such as food or climate change.
<em>The ATP molecule can store energy in the form of a high energy phosphate bond joining the terminal phosphate group to the rest of the molecule. In this form, energy can be stored at one location, then moved from one part of the cell to another, where it can be released to drive other biochemical reactions.</em>
As far as I know, radioactive dating is the measure of radioactive substances in a fossil or something. Like the fossils have a radioactive substance in them, it is the only thing that can show how long the fossils been aging, therefore being able to show the date. And thats how radioactive dating works, and that is how a paleontologist uses it
