Biogeographic isolation means that a population is separated and there are two populations in two different areas. As normal mutations take place, but certain mutations will be seen as advantageous in the different areas. For. Example if an area had taller trees the organism may develop a gene to grow taller. This is then passed down to offspring. This process continues so that more gene differences are created within the species and the frequency of these alleles increased: leading to two different species developing-

Stella [2.4K]
It is important to make the client understand that while alcohol might not be the cause of their problems or all of their problems it does affect the process of their decision making depending on the situation and how they feel towards different situations. A short-term goal would be to go a week without drinking alcohol and to note their changes in mood, behavior towards others and different challenges that they face. Another option is to set a "challenge" to see how long the client can go without the consumption of alcohol, the longer they go without the bigger the changes they will see in their day to day life.

At the coordinates 45 degrees W & 72 degrees N it is 9:32 AM. What time is it at the coordinates 75 degrees W & 45 degre
garik1379 [7]

Answer:

The correct option is;

7:32 AM

Explanation:

The information given are;

The time at 45 degrees W and 72 degrees N = 9:32 AM

The variation of time with lines of longitude  is given as 15 degrees for each 1 hour variation, therefore, where we have the other location at 75 degrees W and 45 degrees S, the difference in the longitude = 75 - 45 = 30 degrees west  of the initial location

Moving west is in the opposite direction of the Earths rotation, therefore, we subtract 1 hour for every 15 degrees giving 30/15 = 2 hours subtracted

The time at 75 degrees W and 45 degrees S is therefore, 9:32 AM - 2 hour = 7.32 AM

The latitude of a place left out in the calculation of the relative time of a place.
