William is developing the model shown below to illustrate the process of photosynthesis. He plans to use the model to explain how photosynthesis transforms both energy and matter.
The diagram shows a chloroplast. In the light-dependent reactions, light strikes the thylakoids, water enters, and oxygen is released. In the light-independent reactions, carbon dioxide enters a cycle and sugars leave the cycle.
Earth systems include the biosphere, atmosphere, and geosphere. Use the model to explain how photosynthesis acts to transfer carbon between two Earth systems.
Answer:
The correct answer is - Photosynthesis takes carbon from the atmosphere and brings it to the geosphere and into plants.
Explanation:
Photosynthesis is the process that involves converting light energy to chemical energy stored in the form of sugars with the help of carbon dioxide and water as reactants.
The carbon is pulled from the atmosphere in the form of carbon dioxide for the process to the geosphere and then used by the plants (biosphere). In plants, it is trapped by the chlorophyll present in chloroplasts and water is entered in the light-dependent reaction and carbon dioxide is used in the light-independent reaction.

Islands like St. George Island and Dog Island are common along all coastlines in Florida (Merritt Island is another example). Identify the coastal feature that these islands represent and describe the formation process of these islands.
Answer:
These islands are barrier islands.
Explanation:
Barrier islands are islands in front of the mainland that separate part of the sea from the open sea. They lie parallel to the coast and have an elongated, narrow shape. On the sea side, dunes often shape the surface, on the land side they are flat. They were created by deposits of waves, currents and wind. Their formation requires a shallow coastal fore, a sufficiently large sediment store and a weak to moderate tidal range.
What are two conditions you need for air mass formation?
Hills/Moisture
Flat Terrain/Same Moisture
Hills/Rivers
Mountains/Lakes
Answer:
Flat terrain/same moisture
Explanation:
Ive done a test that had this question and got it right.
The two conditions you need for air mass formation are flat terrain and same moisture. The correct option is B.
What is air mass formation?It is Known as source regions, air masses form over large surfaces with uniform temperatures and humidity.
Low wind speeds allow air to remain stationary for long enough to absorb the characteristics of the source region, such as heat or cold.
When the atmosphere comes into contact with a large, relatively uniform land or sea surface for a long enough period of time, the temperature and moisture properties of that surface are acquired. The major air masses on Earth originate in polar or subtropical latitudes.
Air masses form over large surfaces with uniform temperatures and humidity, which are referred to as source regions, as well as flat terrain and the same moisture.

If the epidermis is such a good barrier, how can cortisone easily travel through it?
Answer:
cortisone is a lipid-soluble molecule hence can pass through the epidermis
Explanation:
Our adrenaline glands secrete various hormones including cortisol (also known as hydrocortisone) and corticosterone.
They belong to a group of steroid hormone bodies known as glucocorticoids and are used in a wide range of physiological processes such as inflammation regulation.
Pharmaceutical derivatives of these natural glucocorticoids include dexamethasone, fludrocortisone, prednisone, prednisolone, triamcinolone, which differ in strength. As all glucocorticoids have a similar effect, they all fall under the common name "cortisone".

Hello amyrabogan90, The problem is mostly highlighting the distinct differences in both of the animals. By looking at the animals we can see that the rather large brown bear has evolved and adapted to its environment by growing a thick layer of fur and fat. This allows the bear to not only stay warm during the especially cold winters but go without eating for an extended period of time as sources of food become increasingly scarce. This starkly contrasts the qualities of the buck pictured on the left. Bucks are much slimmer and have a relatively light coat. This allows them to move quickly to avoid predators and allows them to stay alive on a herbivores diet of grasses and other vegetation. Bucks are also highly competitive with other males and can often be seen fighting each other for mating rights. For this reason the buck will grow a large set of antlers in order to fight with.

What is overgrazing?Overgrazing occurs when plants are subjected to intensive grazing for an extended period of time or without adequate recovery time.
It is caused by livestock in poorly managed agricultural applications, as well as game reserves and nature reserves.
Overgrazing can significantly decrease ground cover, allowing wind and rain to erode and compact the land.
This reduces the ability of plants to grow and water to penetrate, causing soil microbes to suffer and causing serious erosion of the land.

The seed plants became dominant during the late ___ when the climate became ___.
The seed plants became dominant during the late Paleozoic era when the climate became drier and more arid.
The dominance of seed plants during the late Paleozoic era was driven by a combination of their unique reproductive strategies, water-conserving adaptations, and the changing climate that favored their survival and proliferation.
During the late Paleozoic era, which lasted from approximately 298 million years ago to 252 million years ago, seed plants, including gymnosperms and later angiosperms, became the dominant plant group on Earth.
This era is also known as the "Age of Seed Plants" due to the significant diversification and success of seed-bearing plants.
One of the main factors that contributed to the rise of seed plants during this time was the changing climate. The late Paleozoic era saw a shift towards drier and more arid conditions, with the decline of the swampy and humid environments that characterized earlier periods.
Seed plants have several adaptations that allowed them to successfully colonize and dominate these drier environments. One key adaptation is the ability to produce seeds, which are reproductive structures containing embryos and stored nutrients.

Answer:
Among others, two adaptations might be
Avoiding corporal heat lossIncreasing oxygen absorptionExplanation:
Up in the mountains, there is low oxygen, food is scarce, and adverse meteorological conditions. Animals and plants need to develop different strategies to survive. These adaptations involve not only physical and physiological changes but also behavioral changes. To mention a few adaptations, we can name:
Avoiding heat loss. Temperature tends to be very low at highs, so, to avoid heat loss, animals develop shorter legs, tails, and ears. By doing this they reduce the area or surface of heat loss and also avoid getting frozen. In mammals, the coat is also very important. A thick coat helps them maintain a constant body temperature and keep warm. Some amphibians might also develop a thicker skin as they can not regulate their temperature, and it also helps them not to dehydrate. Camouflage: Coat is also helpful in camouflaging. Mammals´ hair color depends on their environment. Some animals, such as hares, can also change their fur color depending on the season. During snow seasons they turn white, and during the warmer season, they turn yellow or brown. Size and metabolism: Small mammals lose heat very fast, so they need to keep active and feeding most of the time. They have an elevated metabolism to keep warm. On the contrary, big animals, such as bears, need to hibernate to reduce their metabolism and get to survive, otherwise, they would need many reserves to cover their energetic requirements. Oxygen absorption: Some animals have adapted to the lack of oxygen by increasing their heart and lungs capacity as well as their capability to absorbing more oxygen from the blood.Which gases are carried by red blood cells?
