D. blood vessels

Explanation:
Nerves are carried from the eyes to the brain.
The picture shows a pika, a small mammal found in grassland ecosystems. The vast grasslands of the Tibetan plateau are home to the plateau pika. The numerous pikas are prey for many predators of the grasslands, which serve as a major watershed for much of the area. The watershed drains large quantities of groundwater during the rainy season or the monsoon season. Pikas have extensive burrows that help drain groundwater rapidly and are used as nesting sites by many bird species. However, many people advocate the eradication of the plateau pikas because they compete with livestock for grass.
1. The ecosystem will become unstable because predators will have fewer prey, the birds will have fewer nesting sites, and the area downriver will become vulnerable to flooding without the burrows to aerate the soil and provide drainage for monsoon rains.
2. The ecosystem will become more stable because the pika will be replaced by other species of small mammals that can fill the niche, bird species will adapt to nesting aboveground, and the soils will become compacted without the burrows.
3. The ecosystem will become unstable because the predators will migrate to nearby ecosystems, the birds will nest in nearby trees, and the soils will be aerated by other small mammals.
4. The ecosystem will become more stable because the pika will no longer be there to eat the grasses, the birds will migrate to other ecosystems during nesting season, and the soils will be able to absorb more of the monsoon rains without the pika burrows.
Answer:
Option A is correct
Explanation:
Given
Pika are eaten by many animals of the grass land. The burrows of Pika are helpful in draining the ground water rapidly and the burrows also acts as nesting site for many bird species. Pikas consume grass and hence they are competitors of livestock animals.
Removing Pikas from this ecosystem will destabilise the ecosystem as all the grass land predators will not get sufficient food. If Pika will not be there, then their burrows too will not exist and hence the excess ground water cannot be absorbed. Also the bird species will not be able to use burrows as nesting site.
Hence, option A is correct

Describe a challenge that would be encountered and a success of one of the new rats to another be environment (example: the rat living on island B now moves to island D)
Complete question:
Directions: Read the descriptions of the four islands presented in the lesson.
1. List two new traits that each new species of rat might demonstrate as it adapts to the conditions on each island.
2. Introduce one of the four new rat species to another island and describe one challenge it would encounter and one success as it adapts to its new environment
Island A:
The island is fairly flat with an occasional hill. The ground is made of soft dirt, and several species of shrubs grow toward the center of the island. There is no animal life on land, but the water around the island is teeming with fish. The island is surrounded by a coral reef, and the shore is sandy with no algae growing on it. Freshwater is available.
The rat on Island A:
1.
2.
Island B:
This island has a rocky shoreline. Numerous tide pools dot the island along the shore where the wave action is somewhat sheltered by rocky outcrops. The tide pools host barnacles, abalone, sea urchins, and crabs. Algae grow all around the island; however, the growth of algae is quite sparse in the tide pools where the various animals feed. The current is quite strong along the rocky outcrops where the algae grow best. Freshwater is available.
The rat on Island B:
1.
2.
Island C:
The island is somewhat barren. A few species of cactus thrive on the bare rocks, and a large, cactus eating tortoise inhabits the island. A species of very large birds’ nests on the island annually. The birds build their nests on the rocks and protect their eggs from the sun by standing over the nests with outspread wings. The nests are always found on the windy side of the island, which is somewhat cooled by offshore breezes.
The rat on Island C:
1.
2.
Island D:
This island is an extinct volcano. Vegetation on the island changes as the altitude increases. Grasses grow at the base of the volcano, but farther up the volcano’s slope, the grasses give way to low shrubs. Halfway up, the island becomes quite lush; tropical plants and trees dominate the landscape. At this altitude, the island experiences frequent rain showers. Two species of birds inhabit the island. One is a raptor that preys on the smaller birds. The other fishes the waters approximately one mile offshore. Both of the bird species nest in trees.
The rat on Island D:
1.
2.
Answer:
The rat on Island A:
1. Behavioural adaptation → Diurnal habits, as there are no predators that might attack them.
2. Morphological adaptation → Flat feet to move on the sand and Long strong nails to dig in the soft dirt and reach the roots of the shrubs which are a nutritious source of food.
The rat on Island B:
1. Morphological adaptation → Strong extremities to move along the rocky shoreline, to avoid sudden wave impacts, and handle to swim counter-current if they fall.
2. Morphological adaptation → Strong mandibles, well-developed masseteric and temporal muscles, and teeth adapted to feed on barnacles, abalone, sea urchins, and crabs.
The rat on Island C:
1. Stress-induced → Reduced transpiration rate due to the limited water availability.
2. Behavioural adaptation → Skills to compete for scars food with the tortoise avoiding its attack or presence.
The rat on Island D:
1. Morphological adaptation → Waterproof coat, due to the frequent rain showers.
2. Morphological adaptation → Vestigial nails, as they do not need them to get food.
Introduction of a Rat from island C to island D.
Challenge: They need to regulate water loss by increasing the transpiration rate. They need to grow fur adapted to excessive water.Success: They are good competitors with special skills.Explanation:

(Ch. 27.4) Many people are allergic to substances in the environment, such as ragweed pollen, as well as foods, such as peanuts. Which of these statements BEST describes an allergic reaction to one of these substances? (1 point) A. The substance is similar or identical to human antigens, and so it triggers an immune system response. B. The substance invades the body and causes damage to tissues, which triggers an immune system response. C. The substance does not directly harm tissues and is not a pathogen, but nevertheless triggers an inflammatory response. D. The substance invades the body and triggers a response from the respiratory system or digestive system, but not the immune system.
Answer:
C. The substance does not directly harm tissues and is not a pathogen, but nevertheless triggers an inflammatory response.
Explanation:
When a person is allergic to a substance, his or her immune system recognizes a harmless substance, such as components in food, pollen, or dust, as a treat. As a consequence, it starts an immune response that leads to inflammation. The substance that starts the allergic reaction is called an allergen, and it is not a pathogen because it is not a real threat to the body since it does not infect cells. When the allergen enters the body, it binds to antibodies that are in contact with a special type of cell. These specific cells will release a substance known as histamine. Histamine will produce an inflammatory reaction affecting different tissues in our body. For example, it can make us sneeze, have a running nose, swelling parts of our body, have itchiness and redness, amongst others.
