Answer:
The marine iguana is the only lizard in the world with the ability to live and forage at sea and is endemic to the Galapagos Archipelago. There are eleven very similar subspecies, found on different islands, with those from Isabela and Fernandina being the largest. The adults are black for most of the year, however the males change colour during the mating season – with different subspecies adopting different colourations. Near Española and Floreana they are most colourful – turning bright green and red; on Santa Cruz they are red and black; and on Fernandina they become dull green and brick red. The juveniles are generally black, with a lighter dorsal stripe than the adults. During the mating season males fight for dominance over harems of females, which they will fiercely defend from rival males.
Marine iguanas are not a very agile species on land, but they are excellent swimmers – moving easily through the water as they feed on algae. Larger individuals go further out to sea and use their powerful claws to grip on to rocks in strong currents to feed, whilst the smaller ones stay inshore near rock pools, feeding on algae exposed at low tide. Due to the high concentration of salt in their diet, marine iguanas filter their blood at the nose and sneeze out the excess salt, often forming salt crystals on the snout.
Despite not being truly social, iguanas are highly gregarious – especially on cold nights when they tend to group together to conserve heat. In the morning, they bask in the sun, absorbing heat with their black scales until they have enough energy to swim out to sea to forage. Upon entering the water, their heartbeat slows to half its normal pace in order to conserve energy and allow them to feed for as long as possible.
In Galapagos
Where to see them: They can be seen in coastal regions on the islands of Isabela, Fernandina, Española, Floreana, Santa Cruz and other islets around them.
When to see them: They live on the islands all year round, with the mating season occurring between January and March. They are active during the day and spend a lot of time on rocks basking in the sun.
Threats: The introduction of cats and dogs by humans has greatly affected the numbers of marine iguanas as they predate upon the juveniles, which are poorly adapted to defending themselves against large land predators. El Niño periodically decreases the iguana population (by up to 85%), as it cuts short their food supplies. Oil spills may also have similarly dramatic effects on the population. They could also be threatened by marine plastic pollution – specifically microplastics.
Conservation: The marine iguana is protected under Ecuadorian law and is listed under CITES Appendix II. Currently, we are working with partners to assess the risk of marine plastic pollution to marine iguanas as part of our Plastic Pollution Free Galapagos programme. GCT has funded a research project investigating the population dynamics of the marine iguanas on San Cristobal as there may in fact be more than one species of marine iguana present on the
Explanation:
Unlike land lizards, marine iguanas have blunt snouts that help them feed on algae underwater. They also have flattened tails that help them swim efficiently. 4. Marine iguanas typically spend only a few minutes underwater eating but can spend up to 30 minutes at a time submerged.

In 2001, a population of 2,500 poison dart frogs lived in the Amazon rain forest. Due to increased deforestation, the population dwindled to 25 frogs in 2019. New government regulations were enacted in 2022, successfully putting an end to the deforestation of the Amazon rain forest.
Once deforestation was stopped, the poison dart frog population was able to recover. By 2050, the population reached 8,000 frogs. Of that population, 20 are

Which of these statements about ocean waves is true?
A. Water molecules move in a circular path but basically stay in one place.
B. Water molecules move sideways perpendicular to the wind.
C. Water molecules move forward in the direction of the wind.
D. Water molecules in a wave move only up and down.
The statement that is true about the ocean waves is that Water molecules move forward in the direction of the wind.
Option C
What are ocean waves?The basic definition of the waves is that a wave is a disturbance along a medium which transfers energy. In the case of the ocean, we know that the energy is transferred as the water is in motion from one point to the other.
The movement of the waves of the ocean is always driven by the wind that is blowing in the sea and as such the waves that is generated in the sea would move in the direction of the wind.

In North Carolina, demand for fresh water has increased dramatically. One of the main reasons for this is increased water use for agriculture. Respond to the following in 3–5 sentences:
Relate one effect of agricultural water use on North Carolina's river basins.
Relate one conservation strategy that would reduce the effect of agricultural practices on water quality
Agriculture is an activity that requires a lot of fresh water.
This is because agricultural crops need large amounts of water to grow and remain productive. In a situation of large-scale agricultural production, this need for water is even greater, causing producers to use large quantities of water that is necessary for the consumption of the population.Give the detailed explanation?In order to conserve fresh water and keep it at high quality levels to be used both in agriculture and for human consumption, it is necessary that agricultural producers allow the maintenance of riparian forests, use more biodegradable pesticides or with low impact on nature and pay attention to irrigation equipment to avoid waste.
In addition, many producers waste water and pollute it with an excess of pesticides and deforestation.

- Matthew :)
Erosion refers to the process of wearing away or removal of material from the Earth's surface, primarily through the action of natural agents such as water, wind, ice, or gravity. It involves the transportation and deposition of sediment and soil from one location to another.
Erosion occurs when the forces of these agents exceed the resistance of the surface materials, leading to the gradual or rapid removal of soil, rocks, or other geological features. The eroded materials are then transported and may be deposited in different areas, contributing to the reshaping of landscapes over time.
Erosion can have both natural and human-induced causes. Natural erosion processes, such as water erosion caused by rivers or wind erosion in arid regions, are part of the Earth's natural geological cycle. However, human activities, such as deforestation, overgrazing, construction, and improper land management practices, can accelerate erosion rates and cause significant environmental damage.
Overall, erosion plays a crucial role in shaping the Earth's surface, creating landforms like valleys, canyons, deltas, and beaches. Understanding erosion processes is essential for managing and conserving natural resources and mitigating the negative impacts of erosion on ecosystems and human activities.

Why is the rainfall pattern different on the Mountains of Kohala and Mauna Kea?
The Mountains of Kohala and Mauna Kea are located on the Big Island of Hawaii and have different rainfall patterns due to their geographic location and topography.
Where is the location of Mauna Kea?Kohala is located on the northern part of the island and is the oldest volcano in the Big Island, shielded from the prevailing trade winds by the taller volcanoes of Mauna Kea and Mauna Loa.
The moisture carried by the trade winds falls on the eastern side, and much less falls on the western side. Kohala, being located on the leeward side, receives less rainfall and is drier than the windward side.
Mauna Kea is located to the south of Kohala. It is also located on the windward side of the island. Therefore, it receives more rainfall due to the moisture carried by the trade winds. As the air rises over the mountain, it results in more precipitation on the windward side.
Therefore, the rainfall pattern is different on the Mountains of Kohala and Mauna Kea due to their location relative to the trade winds and the topography of the island.
