         The variety of animals, plants, fungi, and even microorganisms like bacteria that make up our natural environment are all included in what is known as biodiversity. These various species and critters collaborate in complicated web-like ecosystems to keep things in balance and support life.

      In order to make communities more resilient and less vulnerable to shocks like climate change and natural catastrophes, biodiversity is crucial. Ecosystems with the ability to control climate and reduce floods are unstable as a result of biodiversity loss.

          The term "biodiversity" describes the range of plant and animal species that are found in a given location. It can be divided into the three categories below: Genetic variety is the variation found within species. Species diversity refers to the variety among species. Ecosystem diversity refers to the variety among ecosystems.

       Land use change (mainly for large-scale food production), which is responsible for 30% of the global biodiversity decline, is the primary direct cause of biodiversity loss. The second major factor, accounting for 20%, is overexploitation (overfishing, overhunting, and overharvesting) for goods including food, medicine, and timber.

         There are five main risks to biodiversity, according to the UN's Convention on Biological Diversity. Changes in land and sea use, direct exploitation of natural resources, climate change, pollution, and invasive species are listed here in decreasing order.

Answer:

By the late 1830s, botanist Matthias Schleiden and zoologist Theodor Schwann were studying tissues and proposed the unified cell theory. The unified cell theory states that: all living things are composed of one or more cells; the cell is the basic unit of life; and new cells arise from existing cells

Robert Hooke: (1663-1665)- The cell was discovered by Robert Hooke in 1665. He examined very thin slices of cork and saw many tiny pores. However, Hooke did not know their real structure or function.

Anton Van Leeuwenhoek: (1674-1683)- Leeuwenhoek made a microscope of glasses used by drapers by polishing tiny lenses of great curvature which gave magnifications up to 270× diameters, the finest known at that time.Leeuwenhoek was the first to see and describe bacteria(1674), yeast plants, the life present in a drop of water, etc.

Theodor Schwann(German zoologist):(1837-1839)- Matthias Schleiden found that all plants are composed of cells, and shared the finding with Schwann, who had found similar structures in the cells. Other researchers confirmed the similarity, after which he concluded, "All living things are composed of cells and cell products". This became the cell theory.

Matthias Schleiden(German botanist):(1839)- He stated that different parts of the plant organism are composed of cells. He also recognized the importance of the cell nucleus and told about its connection with cell division.

Rudolf Virchow:(1855)- Rudolf Virchow suggested that all cells come from pre-existing cells. His aphorism 'Omnis cellula e cellula' means every cell originates from pre-existing cell became the foundation of division, even if the process was not fully understood then.

The process occurring at the sensory receptors that convert physical energy into coded neural activity that the nervous system can process is called c. sensory transduction

In the field of science, we can define sensory transduction as a process by which a change in the physical environment is recognized by the sensory receptors. This information is changed into electrical signals that are transported along the neurons. The neurons transmit these action potentials to the CNS which interprets it and sends signals for producing a response through the effector neurons.

The sensory receptors detect any kind of environmental change and the physical energy of the neurons changes into a neural activity that is initiated by the nervous system in recognition of this change by the sensory receptors.

The prediction is that cell will produce some ATP but in much lower amounts than if oxygen was present if oxygen was removed from the muscle cell.

This is referred to as the process in which an organism obtains energy which is usually in the form of ATP by combining oxygen and glucose, resulting in the release of carbon dioxide and water and is a vital metabolic process in the body.

Photosynthesis on the other hand is referred to as the process in which plants manufacture their food in the presence of sunlight and some compound such as water etc.

Since oxygen is vital in the production of energy then it therefore means that if oxygen was removed from the muscle cell then there will be a lower amount of ATP (energy) produced thereby making it the correct choice.

In one simulation, they are asked to change the initial concentrations of several gases, one at a time, to see the impact on ATP production in a muscle cell. If the students begin by removing oxygen from the muscle cell, what should they predict will occur?

Explanation:

The blood can transport carbon dioxide in three different ways. Plasma proteins or haemoglobin hold it in place, it is dissolved directly in the blood, or it can be converted into bicarbonate.

Carbon dioxide is primarily transported by the bicarbonate system. The carbon dioxide diffuses into the red blood cells. Inside, carbonic anhydrase converts carbon dioxide into carbonic acid (H2CO3), which is subsequently hydrolyzed into bicarbonate (HCO−3) and H+. The H+ ion binds to haemoglobin in red blood cells, and bicarbonate is transported out of the red blood cells in exchange for a chloride ion. It is called the chloride shift.

The bicarbonate leaves the red blood cells and enters the blood plasma. The lungs transport bicarbonate back into the red blood cells in exchange for chloride. The H+ dissociates from haemoglobin and combines with bicarbonate to form carbonic acid with the help of carbonic anhydrase, which then catalyzes the reaction to turn carbonic acid back into water and carbon dioxide. As a result, carbon dioxide is expelled from the lungs.

The process by which organisms combine oxygen with food molecules, rerouting the chemical energy contained in these molecules into life-sustaining processes while excreting carbon dioxide and water as waste, is known as cellular respiration.

Organisms mix oxygen with food molecules during cellular respiration, directing the chemical energy in these substances toward life-sustaining processes while excreting carbon dioxide and water as waste.

While cells are respiring, oxygen may be present or not. However, because the cell seems to "respire" by ingesting molecular oxygen (as an electron acceptor) and releasing carbon dioxide, the process is essentially known as "cellular respiration" (as an end product).

The stratosphere warms up as it ascends because it lacks turbulence and Due to variations in solar UV light the thermosphere behaves differently.

In contrast to the troposphere, the stratosphere actually warms up as it ascends! The stratosphere's air lacks the turbulence and updrafts that characterize the troposphere below due to the trend of rising temperatures with altitude.

The very significant ozone layer is found in the stratosphere. The ozone layer aids in shielding us from the sun's ultraviolet (UV) rays. In actuality, the ozone layer filters out the majority of the UV rays the sun emits at us.

Without this layer of defense, there would be no such thing as life as we know it.

The thermosphere is the portion of the atmosphere between 85 and 500 km altitude that contains the ionosphere.
