A species of squirrels were split in half when a tornado swept through the forest.
Half of the squirrels ended up in an environment near a pond. The other half ended up on rocky ground. They were too far apart to reunite. Ten years later, both of the squirrel populations' allele frequencies had changed to be more fit for their environments. The pond squirrel population and the rocky ground squirrel populations could no longer mate together.

Answer: P-waves are the fastest, can travel through solids, liquids, and gases. S-waves can only travel through solids. Surface waves are the slowest, most destructive
Explanation:
P-waves can travel through both solid materials like rock and fluids like liquid and gas. They travel much faster than the other seismic waves. For example, some animals have been known to hear P-waves and react even before the shaking of the ground begins
S-waves can only pass through solids; they disappear in liquids and gases
Seismic waves are surface waves which roll over the surface of the earth. They can be found during volcanic activity and landslides

MONOCULTURE AND THE FOOD SUPPLY
In 2011, scientists announced that the Cavendish banana, the banana that most frequently makes it to American consumers, could be wiped out by a fungus if the fungus reached fields in Latin America where the banana is grown. It had happened before with the Gros Michel banana, which was wiped out between 1906 and 1960 and is no longer grown by farmers. The reason for scientists' concern: monoculture.
Monoculture is a practice common among farmers. In most fields, you will find a single crop and these plants are not very genetically diverse. This means they are less able to adapt to environmental changes and less able to fight off diseases. Many scientists are concerned that the practice of monoculture farming means that many crops, including bananas, may be subject to total loss or even extinction.
Heirloom Plants
One way that scientists think that food supplies can be protected is by using heirloom plants. An heirloom plant is a plant that was once grown by farmers but is not used in modern monoculture farms. Many heirloom plants are more genetically diverse than modern varieties, which mean they are better able to adapt to environmental change. They are also more likely to survive an attack by a pest or infection by a disease or fungus. However, heirloom plants usually do not produce as much food as modern varieties do.
Organic Farming
Organic farming combines older agricultural practices with modern practices and does not involve the use of synthetic materials such as manmade fertilizers and pesticides. It relies on scientific knowledge about the interactions among organisms and about natural materials that can be used to fertilize plants and control pests. Organic farming does not generally involve monoculture, and an organic farm will have many different kinds of crops. Organic farming practices usually reduce the chance of total crop loss, but like heirloom plants, organic farms are often less productive than conventional farms in terms of volume of food.
Genetically Modified Organisms
Genetically modified organisms, or GMOs, are organisms that have been genetically engineered by people. Many scientists think that concerns over the risks of monoculture can be alleviated by directly changing the genes of crops. They argue that the crops can be given resistance to pests and disease, can be modified to withstand drought, and can be engineered to produce more food. However, many people are concerned about the safety of GMOs, so they are highly controversial. The technology is new and involves the use of bacteria to insert genetic material, so people are concerned that the organisms may negatively affect human health.
Because of what scientists have learned about monoculture, they are:
not pushing for a change in farming.
asking for legislation mandating GMOs.
suggesting ways to protect food supplies.
telling farmers they need to grow fewer kinds of crops.
Answer: suggesting ways to protect food supplies

A remarkable three-way relationship appears to have evolved between an ant, a butterfly caterpillar, and an acacia in the American southwest. The caterpillars have nectar organs which the ants drink from, and the acacia tolerates the feeding caterpillars. The ants appear to provide some protection for both plant and caterpillar.
What is the relationship between the three organisms?
Answer:
Mutualism
Explanation:
Mutualism refers to mutually beneficial interactions between different organisms.
The acai tolerates the feeding of caterpillars, which then possess nectar that acts as food for the ants. The ants protect the caterpillars and the tree.
The tree benefits from the presence of the ants. The ants benefit from the caterpillars, and the caterpillars benefit from the ants and the trees.
Alex volunteers for an experiment being conducted by a group of neurosurgeons. As part of the experiment he is taken to a dark room and a part of his brain is activated with electricity. For a moment Alex sees flashes of light even though the room is pretty dark
Answer:
This question is incomplete; the remaining part is as follows:
Which of the following best explains Alex's experience?
a. The amygdala in Alex's brain is damaged.
b. Alex's brain has unstable dopamine levels.
c. Alex's occipital lobe is artificially stimulated.
d. Alex's Wernicke's area is artificially stimulated.
The answer is C. Alex's occipital lobe is artificially stimulated.
Explanation:
According to this question, Alex is involved in an experiment involving the electrical activation of a part of his brain in a dark room by neurosurgeons. This causes him to see flashes of light despite the dark room he was placed.
Based on this, it can be said that the part of his brain that was activated is the OCCIPITAL LOBE, which is one of the four major lobes in the cerebrum. The occipital lobe is located at the rear of the head where it functions relatedly to VISION in organisms. The occipital lobe is responsible for the processing and interpretation of visual contents.
Therefore, in this case, Alex was able to see flashes of light even in a dark room because his OCCIPITAL LOBE IS ARTIFICIALLY STIMULATED by the electrical current.
