on an island there are three mice populations. Population 2 cannot contact populations 1 and 3. What name is given to this situation?
Answers
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.

Answers
Answer:
C. The demand for beef would decrease.
Explanation:
The demand for beef would be unaffected be the expected change in the demand for beef, ceteris paribus. The correct option is C.
Thus, Consumers might be more likely to pick vegetarian options over beef due to cost considerations.
As a result of recent technological advancements that have made vegetarian meals more affordable to manufacture.
All else being equal (ceteris paribus), this shift in consumer preferences brought on by the relative affordability of vegetarian meals is expected to lead to a decline in the demand for beef.
Thus, The demand for beef would be unaffected be the expected change in the demand for beef, ceteris paribus. The correct option is C.

why do chloroplasts make energy carriers during the light reactions?
Answers
Answer:
consist of array of chlorophyll molecules. *** The absorb energy excited electrons to a higher energy level. ... *** As H+ diffuse through ATP synthase, down their concentration gradient, the enzyme uses the energy of the moving ions to ATP.
Explanation:
Chloroplasts make energy carriers such as NADPH in which the light energy is caught up. Together with carbon dioxide they are used to synthesis glucose during light reaction in photosynthesis.
What is light reaction in photosynthesis ?The first series of events that start the process of photosynthesis require light and are referred to as light reactions or light-dependent reactions since they depend on light as their energy source.
Light energizes the electrons in the chlorophyll molecule as it reaches the chloroplast. These electrons accelerate to higher energy levels because they have taken in or caught that energy and are now carrying it. Excited electrons have high energy. Who wouldn't be thrilled to have the capacity to sustain life?
Chlorophyll is left at a loss when the excited electrons depart to take part in other reactions; eventually, they need to be replaced. In order to break water molecules during that replacement process, an enzyme complex and light are both necessary. Hence, energy carriers plays a significant role in light reaction.

The negative membrane potential in a resting neuron is primarily due to :___________
a. high levels of chloride ions in the cell. diffusion of potassium out of the cell.
b. a higher permeability of the membrane for potassium compared to sodium.
c. both diffusion of potassium out of the cell and a higher permeability of the membrane for potassium compared to sodium are correct.
Answers
Answer:
c
Explanation:
When the membrane of the neuron is in a state of rest, the interior of the cell has a more negative charge in relation to the exterior, therefore option "c" is correct.
What is the membrane potential in a resting neuron?It is a phenomenon that occurs when the nerve cell membrane is not altered by action potentials.
Characteristics of a resting neuronThe resting potential is determined by the concentration gradients of the ions, both inside and outside the neuron, and by the permeability of the membrane.When a cell is at rest, the potassium channels are open, the potassium will tend to flow outwards (K ions), they are positive charges, therefore the cell interior will be negative with respect to the cell exterior.Therefore, we can conclude that the resting potential of a membrane occurs when they are not transmitting signals.

Cancer cells can arise in a variety of ways, the most common, however, tends to be genetic mutations.
Genetic mutations can occur during the life of a cell due to outside factors such as:
The food we eatThe environment we expose the cell toThe substances that touch the cell (e.g skin cells)That being said, the most common time for a genetic mutation to take place is during cellular division. During this time the DNA that encodes the cells is duplicated. Genetic mutations in this DNA sometimes cause the elimination of programmed cell death.
Programmed cell death is what tells a cell when it should stop growing and dividing. This is a regulatory function designed to keep the number of cells at a balance, growing only when needed. As this cell multiplies, this produces an increasing number of cells that will not die. The accumulation of these cells is referred to as cancer.
