Explanation:

This is because in meiosis the chromosomes split apart.

Corals glow because they contain tiny algae called zooxanthellae. These algae live inside the coral's tissues and provide the coral with food and oxygen.

How to explain the information

In return, the coral provides the algae with a safe place to live and carbon dioxide. When the water temperature gets too warm, the algae start to die. This causes the coral to lose its food source and turn white, a process called bleaching.

If we don't take action to reduce greenhouse gas emissions, the oceans could be too warm for any corals to survive in as little as 30 years.

About half of the coral reefs on the Great Barrier Reef have died in the past 30 years.

Richard is optimistic because he believes that we can still save the coral reefs if we take action to reduce greenhouse gas emissions and protect coral reefs from other threats such as pollution and overfishing.

Answer:

1) Weathering, Erosion, Disposition

2) Physical weathering is the breakdown of large rocks into fragments by physical forces; the chemical composition of the rock is not changed. Chemical weathering is the breakdown of rock by chemical reactions; the chemical composition is changed.

3) The four forces of erosion are water, wind, gravity, and glaciers.

4) Because the velocity of the river slows down a great deal when it reaches the large body of water, the sediment that the river was carrying is deposited along the mouth of the large body of water.

--------------------------------------------------------------------------------------------------------

Abrasion: Abrasion is the breaking down and wearing away of rock material by the mechanical action of another rock. Three agents of physical weathering that cause abrasion are moving water, wind, and gravity. Also, rocks suspended in thence of a glacier can cause abrasion of other rocks on Earth's surface. This would be a prime example of physical weathering, or mechanical weathering.

----------------------------------------------------------------------------------------------------------

Acid Precipitation: Acid rain causes less erosion than normal rainwater does. Rainwater can break down rocks by dissolving minerals in the rocks. Acid rain is rainwater that is more acidic than normal rainwater. Acid rain can also dissolve the minerals in rocks faster than normal rainwater can. This is chemical weathering.

--------------------------------------------------------------------------------------------------------

Animal actions: Animal and plant mobility is a factor in biological weathering. For instance, a plant may grow in a gap in a rock and, as its roots spread, cause the fracture to expand. A rabbit may also burrow into a crack in a rock, making it wider and eventually separating the rock. This is an example of physical weathering.

---------------------------------------------------------------------------------------------------------

Ice wedging: Ice wedging ,sometimes known as frost wedging ,can also cause rocks to break apart. Ice wedging causes cracks in rocks to expand as water seeps in and the water freezes and expands opening the crack further. Rocks formed under pressure deep within earth can become exposed at the surface. This is physical weathering

----------------------------------------------------------------------------------------------------------

Oxidation: Oxidation is another kind of chemical weathering. It occurs when oxygen from air dissolves in water and combines with chemicals in the rocks to form oxides. if the rock contains a lot of iron, then oxidation produces a brown material called iron oxide. This looks like rust on the rock.

Weathering is the chemical and mechanical breakdown of exposed rock. The chemical changes alter the minerals and make them softer, and mechanical weathering physically breaks rock into smaller and smaller pieces.

Erosion is the REMOVAL of those chemically and mechanically softer and broken pieces of rock from their original locations, by gravity, water, ice or wind. Erosion is transport (and as a result, fresh unaltered rock is exposed to wind, water and weather, and THAT becomes weathered in turn). The material being transported is ‘sediment’: sand, silt, mud and gravel.

Deposition is when the weathered and eroded (transported) material is dropped and settles down elsewhere, forming a ‘deposit’ of transported rock material.

If this deposit remains undisturbed long enough, and is buried by enough arriving material, it will eventually go through compaction and chemical reactions forming cement between the grains - thus resulting in a brand new, sedimentary rock.

Weathering, erosion, transport, deposition, compaction and cementation are part of the ‘rock cycle’.

Let’s start with basalt that form at mid ocean spreading centers. At mid ocean spreading centers rock material from the earth’s mantle continuously melts due to continuous decreasing in pressure from the oceanic crust spreading at this point. The molten rock quickly cools at the earth’s surface and forms rock known as basalt that makes up the oceanic crust all over the world. The newly produced oceanic crust rock slowly moves towards a boundary with a continental crust where the oceanic crust subducts beneath the continental crust due to the oceanic crust having a higher density than the continental crust. This is where things get a bit more interesting.

The fourth correct answer is that sedimentary rock is where fossils are most frequently found.

The preserved remnants of animals and plants that were submerged in sediments like sand and mud beneath ancient seas, lakes, and rivers are known as fossils. Any preserved sign of life that really is typically older than 10,000 years is considered a fossil. Any surviving remains, impression, or evidence of a once-living thing from such a previous geological epoch is referred to as a fossil. Examples include fossilized bones, shells, exoskeletons, animal or microbe imprints in stone, amber-preserved artifacts, hairs, petrified woods, oil, coal, and DNA traces.

According to State of New York Geological Survey, fossils are made through a variety of various chemical and physical processes. Whole-body fossils can be formed by freezing, drying, and encasing in tar or resin to preserve bodily tissues. The first dinosaurs bone was reportedly found in 1677 by Robert Plot, who initially thought it belonged to a huge human. The first geology professor at Oxford University, William Buckland, was the one who first accurately recognized a dinosaur fossil as such.

Sedimentary Rocks: Rocks that are produced from previously existing rocks or fragments of once-living organisms are known as sedimentary rocks. They emerge from deposits that amass on the Earth's surface. Identifiable bedding or layering is typically present in sedimentary rocks.

Explanation:

Photosynthesis is the process of plants converting light energy into food, and letting out oxygen for humans to take in. We take in their oxygen and let out carbon dioxide to help them survive. So the formula for Photosynthesis would be carbon dioxide and water (plants need this to survive) makes oxygen and glucose

Cellular respiration is the process of taking food and breaking it down. It takes the chemical energy out of the food in our stomachs to create ATP. This occurs in the mitochondria, which is known as the powerhouse for this large role in human life. In cytology, we learned how vacuoles store waste products or foods, and transport them out of the cell. The vacuoles remove the waste products created by cellular respiration and remove them.

The formula for Cellular Respiration is oxygen and glucose (from food) turns into water and carbon dioxide.

Answer: A. because the genetic code is universal for all organisms

Explanation:

The genetic code of living things refers to the information that cells in living organisms use to encode genetic information from the DNA and the RNA into proteins.

Every living organism uses the same genetic code and scientists believe this is because we all share a common history in terms of evolution. This homogeneity is advantageous because it enables scientists to be able to compare amino acid sequences across multiple living species.

The organisms that feed on dead and decaying matter are called Saprotrophs.

An organism that feeds on dead and decaying organic matter is called a saprotroph. These organisms are heterotrophic, which means that they obtain their food from other sources. They are important in the ecosystem because they break down dead organic matter and recycle it back into the soil, making nutrients available to other living organisms

Answer:

A. Saprotrophs

Explanation:

Saprotrophs are organisms that obtain their nutrients by feeding on dead and decaying matter. They play a crucial role in the ecosystem by decomposing organic material and recycling nutrients back into the environment.

These organisms secrete enzymes that break down complex organic compounds into simpler substances, such as sugars and amino acids, which they can absorb and utilize for their own growth and energy needs. Examples of saprotrophs include fungi (such as mushrooms and molds) and certain bacteria.

Unlike autotrophs, which can produce their own food through photosynthesis or chemosynthesis, saprotrophs rely on external sources of organic matter for their nutrition. They actively decompose dead plants, animals, and other organic materials, aiding in the process of nutrient recycling and decomposition.

Heterotrophs, on the other hand, are a broader category of organisms that obtain their nutrients by consuming other living or dead organisms. This includes saprotrophs, as well as other types of organisms such as herbivores, carnivores, and omnivores.

Parasites, meanwhile, are organisms that live in or on other organisms, known as hosts, and obtain their nutrients from the host while causing harm or damage to it. Unlike saprotrophs, parasites typically rely on a living host for their sustenance rather than feeding on dead and decaying matter.
