Coral reefs are being harmed all around the world by ocean acidification. A coral reef is an underwater ecosystem that is made up of corals that construct reefs.

A coral reef is an underwater ecosystem that is made up of corals that construct reefs. Coral polyp colonies are bound together on reefs by calcium carbonate. [1] The majority of coral reefs are composed of stony corals, whose polyps gather together.

In the animal phylum Cnidaria, which also contains sea anemones and jellyfish, coral is a member of the class Anthozoa. For support and protection, corals secrete hard carbonate exoskeletons, unlike sea anemones. In warm, shallow, clear, bright, and agitated water, most reefs thrive. At the beginning of the Early Ordovician, 485 million years ago, coral reefs made their first appearance, replacing the Cambrian's microbial and sponge reefs.

The valley floor has dropped by more than two miles relative to the mountains, but erosion has removed the tops and the sediment produced has partially filled the valley, leaving an elevation difference of two miles.

When plates move apart, they create divergent plate borders, which are related to the rift valley development. Mountains are likely to be formed as a result of the movement of convergent plate boundaries toward one another and pressing against one another.

The difference in elevation, which is akin to what you have studied as the difference in height, is the vertical distance between two places (see Section 5.0). Leveling is a fundamental operation in topographical surveys that measures variations in height.

Correct answer is :- fossils

The preserved remains, or traces of remains, of extinct animals are called fossils. The remains of the organism itself are not fossils! They're rocks. An full organism or only a portion of one can be preserved as a fossil. Leaves, feathers, shells, bones, and shells can all turn into fossils. Fossils come in a wide range of sizes. Only a microscope can see microfossils. Microfossils include pollen and bacteria. Macrofossils can weigh several tons and measure many meters in length. Petrified trees or dinosaur bones are examples of macrofossils.

Identical to those seen on high-performance F3B versions.

In theory, any airfoil can be used with flying wings and tailless model aircraft. But the airfoil needs to be carefully chosen if performance is a concern, as it is while competing. If the torsion moment of the airlift is balanced by the right ratio of wing sweep and twist, it is conceivable to employ the same airfoils that are used on high-performance F3B aircraft. The performance loss caused by sweep and twist can be reduced by selecting airfoils with moment coefficients cm c/4 that are near to zero.

In designing the MH 40 series and MH 60 series airfoils, the primary objectives were to (a) achieve low drag values comparable to typical airfoils used on F3B models, (b) cause only small torsion coefficients cm c/4, and (c) improve the maximum lift coefficient compared to existing, low cm c/4 airfoils.

Two G3Ps are needed to make a glucose molecule with six carbons since a G3P molecule has three fixed carbon atoms. One molecule of glucose would need six cycles, or 6 CO2 start text, C, O, start subscript, 2, end text, end subscript, 18 ATP, and 12 NADPH.

According to the typical gluconeogenesis process, trioses (3-carbon sugars) are converted into glucose in plants. That is triose phosphate isomerase and aldolase convert glyceraldehyde phosphate to fructose-1,6-diphosphate, which is subsequently dephosphorylated to produce hexose phosphates.

Six Calvin cycles take place because it takes six carbon dioxide molecules to make one molecule of glucose. So, for the purpose of synthesizing one molecule of glucose, 12 molecules of 3-PGA are created during the carboxylation stage.

Sediment is frequently transported in a zigzag pattern by beach drift, which is a downcurrent process.

Particles (such as sand or other soils) that settle or are deposited mostly on sides & bottom of bodies of water are referred to as sediment. It contributes to the construction of sand bars, beaches, spits, and estuaries and serves as a substrate for aquatic life.

Rocks and possibly even mountains deteriorate in sediments such as sand or mud as a result of erosion and weathering. Chemical weathering commonly called dissolution—is one type of weathering. By washing it in mildly acidic water, this method gradually eliminates stone. For relatively young sedimentary rocks, these three processes produce the necessary components.

Answer:

A jet stream is a type of air current that forms high in the atmosphere. On average, jet streams move at about 110 miles per hour. But dramatic temperature differences between the warm and cool air masses can cause jet streams to move at much higher speeds — 250 miles per hour or faster.

Explanation:

Jets streams play a key role in determining the weather because they usually separate colder air and warmer air. Jet streams generally push air masses around, moving weather systems to new areas and even causing them to stall if they have moved too far away.

The slopes of active Martian volcanoes appear to have been covered with ice and debris flows, and the mineral jarosite, which is considered to have developed in the presence of water, is found in Martian rocks. This undiscovered evidence suggests that there was once liquid water on Mars. Here, choices B and D are the right ones.

On Mars, meanders do exist, but they are not the result of water. Lava-like volcanic flows were what gave rise to it. Researchers came to the conclusion that water was really a significant component in the development of this mineral from the minerals they had isolated from the salt deposits that were present. It's called jarosite.

Additionally, the radar picture demonstrates that ice and debris are in fact extant and were formerly a component of large glaciers. The most important example is this one since radars can readily pick it up. Therefore, the finest instances of this identification of water on Mars are the glaciers and the minerals.

The Atlantic slave trade was the transatlantic trade in Africans, which took place between the 16th and 19th centuries. It was a system of forced migration that was fueled by the demand for labour in the Americas, particularly in the Caribbean and South America.

The primary reason for the Atlantic slave trade was economic. European colonizers in the Americas needed a large and cheap labour force to work on their plantations, mines, and other enterprises. They turned to Africa as a source of labour because of the availability of a large population and the fact that the African continent was already experiencing a history of warfare and slavery.

The Atlantic slave trade was a profitable enterprise for European traders and their African partners, who captured and sold Africans to European slave traders. It was also a deeply inhumane and brutal system that subjected millions of Africans to brutal conditions and a lifetime of slavery. The Atlantic slave trade was officially abolished in most countries in the 19th century, but its legacy continues to have an impact on societies around the world.

The Five golden rules for Safer Food are:  keep clean; separate raw and cooked; cook thoroughly;  keep food at safe temperatures; and  use safe water and raw materials.

1. Keep it Clean

WHO emphasizes that clean cooking practices must be followed in all circumstances. Unhygienic cooking practices can transfer dangerous microbes to your hands, cleaning cloths, kitchen utensils, and especially cutting boards. So have separate cutting boards for vegetarians and non-vegetarians. Also, be sure to wash and sanitize all surfaces and utensils before cooking.

2. Separate raw and cooked foods

Separating raw and cooked foods greatly reduces the risk of cross-contamination. Bacteria from raw foods can be transferred to hands and directly onto countertops, clothing and utensils before finally being transferred to heated foods.

3. Cook thoroughly

Proper cooking kills almost all microbes. Eating hot, glowing food is important because it has a low bacterial count. If the temperature drops below 70 degrees, the number of microorganisms increases significantly. Additionally, you should be careful not to cook food for too long. Otherwise, the nutritional value will be lost. The preferred cooking method to preserve nutritional value is steaming.

4. Keep food at safe temperatures

This means keeping the temperature at a level that minimizes or eliminates the number of bacteria. This temperature is about 60 degrees above and about 5 degrees below. It is important to keep food at safe temperatures and not store cooked food for long periods of time. Also, when consuming preserved food, heat it sufficiently (100°C) before consuming it. To prevent food poisoning, we recommend minimizing refrigeration of cooked foods and keeping cooked foods at room temperature for long periods of time.

5. Use safe water and raw materials

Always use clean water for cooking. Good safety practices include using clean water, choosing fresh and healthy foods, and choosing foods that have been processed for safety.

Blisters, pain, swelling, white or burned (blackened) skin, and peeling skin are the five signs of a burn.

A bubble of clear fluid under the skin known as a burn blister grows when the body attempts to protect a damaged region. Blisters that form as a consequence of persistent friction, rashes, or squeezed skin are not the same as burn blisters.

Dry heat, such as that produced by an iron or fire, can result in a burn. Something moist, like steam or hot water, can scorch you. Burns may result in skin that is red or peeling and can be highly painful.

The fluid that leaks from blood arteries and accumulates around injured tissues is what causes the swelling. Within an injury, swelling often starts to subside after 48–72 hours.

The characteristics of light are as follows. Light is an electromagnetic wave that propagates in a straight line in a process known as rectilinear propagation of light. Light is also a transverse wave, meaning that its particles move in the opposite direction to the direction of the wave's propagation.

Actually, radiation, which is defined as energy that moves as electromagnetic waves, includes visible light. Another way to think of it is as a continuous flow of particle-like "wave-packets," or photons, that move at the speed of light (about 300 000 kilometers per second).

The energy that moves in waves is called light. Many of the characteristics of light are determined by its length or wavelength. For instance, the wavelength determines the color of light and its interaction with matter.

Correct answer is :- Air pollution

When sulfur dioxide (SO2) and nitrogen oxides (NO2) are released into the atmosphere, they are carried by wind and air currents and eventually form acid rain. Acids made of sulfuric and nitric compounds are produced when the SO2 and NOX react with oxygen, water, and other substances. Before dropping to the ground, they then combine with water and other substances.

While volcanic eruptions and other naturally occurring processes do provide a minor amount of the SO2 and NO2 that create acid rain, fossil fuel combustion accounts for the majority of it.
