1. This simply means particles will move from areas with a lot of the same particle to areas with less of that particle to even out the concentration of the particle across the entire solution.
2. Two examples are factors that affect diffusion are temperature and surface area. Basically, as temperature increases, so does the rate of diffusion, and as surface area decreases, so does the rate of diffusion.
3. Facilitated transport occurs when a molecule is too large or cannot cross the membrane freely through a channel protein. A vesicle, formed by the plasma membrane, will form around the molecule and slowly make its way through the membrane by interacting with the non polar tails of the phospholipid bilayer.
4. Osmosis is the diffusion of water across a membrane. Basically, this means water moving into and out of cells with its concentration gradient.
5. A solution is isotonic relative to a cell if the concentration of a particular particle is equal both in the solution and in the cell. A solution is hypotonic if the concentration inside the cell is less than the concentration of the solution, which will cause the cell to swell as fluid enters the cell. A solution is hypertonic if the concentration inside the cell is greater than the concentration of the solution, which will cause the cell to shrink as particles leave the cell. These concepts dictate whether or not diffusion will occur and, if it does, which direction it will occur in.
Hope this helps! :)
<span>The question says,'menstruation does not occur if the ............ The correct option is D. The uterine lining usually build up in order to serve as a bed and support for fertilized a egg. If fertilization does not occur, the uterine lining breaks down and come out as menstruation, but if fertilization occurs, then the uterine lining will not break down but will support the fertilized egg all through the pregnancy period.</span>
Answer:
Kindly check explanation
Explanation:
According to the graph given the number of algae is represented on the y axis while the month of the year is represented on the x - axis of the graph. The change in the number of algae from February is clearly depicted by an upward slope along the y-axis which means that there is continous increase in the Number of algae in the lake during this period, that is between February to June . It could also be seen that around June the optimal number of algaae is achieved as the number of algae tend to fall as we move beyond June.
Phase 1: Starts with the separation between populations. Separated populations become adapted to local conditions and become genetically differentiated over time.
Phase 2: Genetic isolation is completed, reproductive isolation develops mostly in the forms of prezygotic RIMs.
