Does Carbon Dioxide (CO2) move or
does it stay in one spot? Explain.
pls help
Answer : They Do Move
Explanation : They settle into layers based mostly on their molecular weights. However, the Earth's atmosphere is much more expansive than a wine bottle. CO2 does not break down until about 80 kilometers from the Earth's surface, giving atmospheric gases a huge expanse to occupy.

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
1.) What are some of the forms of evidence used to support the theory of Pangaea?
2.) Why aren't the planet's continents in the same formation as they may have once been during the time of Pangaea?
3.) Why is it important to study the theory of plate tectonics and continental drift?
Answer:
1) Alfred Wegener, in the first three decades of this century, and DuToit in the 1920s and 1930s gathered evidence that the continents had moved. They based their idea of continental drift on several lines of evidence: fit of the continents, paleoclimate indicators, truncated geologic features, and fossils.

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:

Give three ways in which plants use the glucose made in photosynthesis.
Thanks
Answer: Energy source. Glucose can used as a substrate and broken down in plant cells by the process of respiration.
Plant energy storage. Thousands of glucose molecules can be linked together to form the complex carbohydrate starch.
Plant building material.
Explanation:
The three ways in which plants use the glucose made in photosynthesis are as follows:
Energy storage.Plant building material.Energy source.What is Photosynthesis?Photosynthesis may be defined as the process through which green plants and some algae synthesize their own food (glucose) with the help of carbon dioxide and water in the presence of sunlight.
Starch is stored in the plants that is a derivative of glucose. It can provide energy to the plants when environmental conditions are unfavorable to synthesize glucose.
Cellulose is another derivative of glucose which utilize in the building of plant cell walls to protect plants from the external environment.
Glucose directly provides energy to the plant cell for the fulfillment of metabolic activities like respiration, protein synthesis, cell division, etc.
Therefore, it is well described above.

Scientists predict that ocean acidity could double (increase 100%) by 2100. What are the effects of ocean acidification on ocean plant and animal life give (2 examples) and on humans (give 2 examples)?
Thank you!
Answer:
Reduce amount of carbonate and dissolve calcium carbonate.
Explanation:
Ocean acidification can negatively affect marine life, causing organisms' shells and skeletons made from calcium carbonate to dissolve. ... Animals that produce calcium carbonate structures have to spend extra energy either repairing their damaged shells or thickening them to survive.
Ocean acidification will affect humans too! It will affect the food we eat since most of our shellfish requires calcium carbonate to form or to fortify their shells. Many of the fish we eat are also dependent on shelled animals for their food source, so the entire food chain is in jeopardy

How can charging occur?
The previous section of Lesson 2 discussed the process of charging an object by friction or rubbing. Friction charging is a very common method of charging an object. However, it is not the only process by which objects become charged. In this section of Lesson 2, the charging by induction method will be discussed. Induction charging is a method used to charge an object without actually touching the object to any other charged object.
