Intentionally altering the Earth's natural systems on a massive scale to combat climate change is known as geoengineering.

With the use of reflective particles sent purposefully into the upper atmosphere, where they can block the sun's warming rays, solar geoengineering aims to reflect incoming sunlight back into space. First, there is carbon geoengineering, often known as carbon dioxide removal (CDR). The other is solar geoengineering, which is additionally referred to as solar radiation management (SRM), albedo alteration, or sunlight reflection. At least three main categories can be used to classify geoengineering proposals:

Theory of abiogenesis suggests the occurrence of life on earth. It was experimentally demonstrated that complex organic molecules were formed of simple non-living entities.

Theory of abiogenesis was a concept proposed by Huxley in which he suggested that the life forms on the earth have been formed spontaneously from the reaction between the nonlife components on the earth.

The complex living forms were believed to be evolved from the simple forms through various biochemical interactions. This was later demonstrated by Urey and miller in their experiment.

Thus, theory of abiogenesis is important in determining the course of evolution on earth.

These are the weights of a potato cube after an experiment of osmosis.

Osmosis is the naturally occurring diffusion or passage of water or other solvents over a semipermeable membrane (one that prevents the passage of solutes, or dissolved compounds). The crucial biological mechanism was initially in-depth investigated in 1877 by German plant physiologist Wilhelm Pfeffer.

Previous researchers had conducted less precise examinations of leaky membranes (such as animal bladders) and the transport of water and escape chemicals through them in opposite directions. Thomas Graham, a British chemist, coined the term "osmose," which is still used to refer to the process, in 1854. A solution will tend to become more diluted by absorbing solvent through a membrane separating it from the pure solvent if the membrane is permeable to the solvent but not to the solute.

When a very high heat and pressure is released on the particles which make is made of, it becomes a metamorphic rock.

One sure way to know that a rock has undergone metamorphism is that there is a difference in the chemical composition of rocks compared to its earlier form.

Rock metamorphism refers to process which occurs when rocks or rock layers changes to metamorphic rocks as a result of their exposure to great heat and pressure.

A metamorphic rock is a rock is formed from previously existing rock as a result of exposure to great heat and pressure which cause a change in their physical and chemical properties.

Some few characteristics of metamorphic rocks include:

So therefore, we can now confirm that when a rock is subjected to high temperature, it can metamorphised.

Organs

Explanation:

Tissues are an aggregate of similar cells and cell products forming a definite kind of structural material with a  specific function, in a multicellular organism. A organ is a grouping of tissues into a distinct structure, as a heart or kidney in animals or a leaf or stamen in plants, that performs a specialized task.

To explain more,

Organs are collectives of tissues that function as a unit. The heart, lungs, skin, and stomach are just a few examples of organs. Systems are what occur when organs cooperate. Your heart, lungs, blood, and blood arteries, for instance, cooperate. The circulatory system is made up of them.

The human body is made up of eleven different systems: the muscular, respiratory, digestive, integumentary (skin), skeletal, circulatory (or cardiovascular), excretory (or urine), reproductive, neurological, lymphatic, and endocrine systems. Every system has a unique function.

To keep you healthy, every body system must cooperate. Together, your muscles and bones support and move your body. Air is used by your respiratory system to take in oxygen. Carbon dioxide is also expelled.

Your digestive tract takes nutrients and water from the food you eat in to your body.

Your body's cells receive oxygen, water, and nutrients through your circulatory system. Your epidermis, excretory system, and respiratory system all function to remove wastes from your cells.

Your nervous system uses electrical impulses to regulate all of these processes. Other systems in your body are impacted if one system isn't functioning properly.

Imagine your body as a structure. A building has a support system, an electrical system, a heating and cooling system, and a plumbing system. Other systems in a facility may be impacted if one system malfunctions.

Consider the electrical system of a building as one illustration. Imagine a mouse gnawed a furnace's electrical line. The heating system wouldn't function without power. The plumbing system can be impacted if this occurs during really cold weather. A frost might cause water pipes to explode. The support system of the structure would be harmed if a lot of water spilled through the walls. Your body's systems must cooperate, much like those of a skyscraper.

Extinction refers to the complete disappearance of a species or group of organisms from the Earth. Extinction can be caused by a variety of factors such as climate change, habitat destruction, competition, predation, disease, and human activities such as hunting and pollution.

The fossil record is one of the most important sources of evidence for extinction events. When a species goes extinct, its fossils can still be found in the rock record, often in a particular layer of sediment that corresponds to the time period when the extinction occurred.

By studying the fossil record, scientists can identify periods in Earth's history when there was a sudden and widespread disappearance of species, which is known as a mass extinction event.

For example, the fossil record shows that there have been five major mass extinction events in the history of life on Earth, with the most famous being the extinction of the dinosaurs at the end of the Cretaceous period.

The extinction of the dinosaurs is marked by a distinct layer of sediment that contains high levels of iridium, which is rare in Earth's crust but is abundant in asteroids and comets. This layer of sediment suggests that a large asteroid impact may have triggered the extinction of the dinosaurs and many other species.

Overall, the fossil record provides valuable evidence for understanding the history of life on Earth, including the occurrence and causes of extinction events.

Explanation:

An isotonic environment outside a cell has same amount of salt, the same as the inside of the cell.

Isotonic solutions are the ones that have the similar concentration of water as well as solutes as cell cytoplasm. Because there is no net gain or loss of water, cells in an isotonic solution will neither shrink nor swell.

When a cell is immersed in an isotonic solution, there is no net flow of water into or out of the cell, and the volume of the cell remains constant.

If the concentration of solutes outside the cell is the same as the concentration inside the cell and the solutes cannot cross the membrane, the solution is isotonic to the cell.

Thus, it has same percentage of salt inside and outside.

In light reaction it includes the use of light energy for the two molecules. The dark reaction is a light independent reaction.

Light Reaction:

In light reaction it includes the use of light energy for the two molecules which is needed for the next stage of photosynthesis  the energy storage molecule ATP (Adenosine tri phosphate) and the reduced electron carrier NADPH. In plants, the light reactions take place in the thylakoid membranes of organelles called chloroplasts. During the light reaction the chlorophyll absorbs light energy which excites some pigments molecules to higher energy levels.

Dark reaction:

The dark reaction is also called the carbon-fixing reaction. It is a light-independent process in which sugar molecules are formed from carbon dioxide and water molecules. The dark reaction occurs in the stroma of the chloroplast, where they use the products of the light reaction.
