on an island there are three mice populations. Population 2 cannot contact populations 1 and 3. What name is given to this situation?
Answer:
Isolation
Explanation:
On a island, there are three mice population in which one population cannot contact other populations. This situation is an example of allopatric speciation.
What is Allopatric speciation?Allopatric speciation is also referred to as geographic speciation. It is also called vicariant speciation. Allopatric speciation is a mode of speciation which occurs when the biological populations become geographically isolated from each other to an extent that it prevents or interferes with the normal gene flow in a population.
There are several factors which are required for the allopatric speciation to take place such as isolation of a population, time, and natural selection in an environment. Earthquakes, floods, and migration all are the ways through which a group of individuals of the same species can become isolated.

What is a specific way that we could test the idea that the bacteria close to and farther away from the rings are different from each other?
will give brainliest
A way you could test if bacteria are different is through Gram Staining
Despite all bacteria are prokaryotic organisms, there are thousands of bacteria species and each species has different characteristics.
Moreover, bacteria are classified into two main groups:
Gram-negative bacteriaGram-positive bacteriaThese differ in their structure as gram-positive bacteria have a thick peptidoglycan layer, while gram-negative bacteria have a thin peptidoglycan layer and an external layer.
This key difference is essential when classifying bacteria because there are specific species for each type. Moreover, this can be tested through Gram staining, as this will show gram-positive bacteria as purple and gram-negative ones as pink or red.

What is happening to the growth of a population in which death rate equals birthrate, but emigration is greater than immigration?
Answer:
Explanation:
A negative growth rate means it is decreasing. The two main factors affecting population growth are the birth rate (b) and death rate (d). Population growth may also be affected by people coming into the population from somewhere else (immigration, i) or leaving the population for another area. i mean
The growth of the population is decreasing.
Growth rate of the population depends upon:--Birth rate
-Death rate
-Immigration
-Emigration
What is emigration?Movement of organism from its residing place to another place.This generally happen because of certain factors like not suitable habitat, occupation, food, etc.To know more about growth rate here

The main function of the Rough Endoplasmic Reticulum is the production of membrane and proteins secreted by the cell.
What is Endoplasmic Reticulum?The endoplasmic reticulum serves as the transport system of the eukaryotic cell, with many other important functions such as protein folding. It is a type of organelle made up of two subunits –
1. Rough endoplasmic reticulum (RER)
2. Smooth endoplasmic reticulum (SER)
It has a continuous nuclear envelope. The endoplasmic reticulum contains ribosomal granules anchored to the cytoplasmic surface of the cisternae is involved in the synthesis and secretion of proteins through membrane-bound vesicles called ergastoplasms.
