Carbon from glucose is essential for the formation of amino acids the process which is responsible for the production of glucose in plants is photosynthesis.
Photosynthesis is the process by which plants or other organisms transforms light energy into chemical energy. During the process of photosynthesis, plants need three basic things to live: water, sunlight and carbon dioxide.
Photosynthesis is the process by which a plant produces its food using energy from sunlight, carbon dioxide from the air and water from the soil. The word photosynthesis can be separated to make two smaller words: ‘photo’ which means light ‘synthesis’ which means putting together
In this process, light energy from the Sun is absorbed by the green substance, called chlorophyll, present in leaves. This energy allows the production of glucose (food) by the reaction between carbon dioxide and water. Oxygen is also produced as a by-product.
Carbon dioxide + Water → Glucose + Oxygen

Answer:
One of the many functions of proteins is to span the plasma membrane and form channels that allow passage of molecules and ions into and out of the cell.
Explanation:
Large, complicated molecules known as proteins perform a wide range of essential functions in the body. They are crucial for the construction, operation, and control of the body's organs and tissues that carry out the majority of their job inside cells.
Numerous millions of amino acids, which seem to be smaller building blocks of proteins, are linked together in lengthy chains to form proteins. To create a protein, 20 particular types of amino acids could be mixed. Each protein's particular function and specific 3-dimensional structure are determined by the order of the amino acids. Groupings of 3 DNA building units (nucleotides), which are regulated by the order of genes, are used to code for amino acids. Cells are supported and given structure by proteins. They permit movement of the body on a greater scale as well. These proteins transport and move atoms and tiny molecules all across the body and inside cells.

Describe and explain how the surface of the early Earth and its atmosphere have changed
to form the surface of the Earth and its atmosphere today.
Earth had essentially no atmosphere when it originated 4.6 billion years ago from a heated mixture of gases and minerals. The ground had melted on it.
An atmosphere developed when Earth cooled, primarily from gases released by volcanoes. It contained methane, hydrogen sulfide, and ten to 200 times as much carbon dioxide as the atmosphere we are surrounded by today. The Earth's surface began to cool and solidify after roughly 500 million years, allowing water to accumulate there. Although life on Earth continued to develop and diversify, such periods of expansion and development were halted by mass extinctions, in which many of the planet's major life forms were either entirely or partially wiped out and many others were freshly established. Such catastrophic extinction episodes are attributed to asteroids impacts, climate change, volcanic eruptions, etc. Dinosaurs were also wiped out in one such event. The largest problem the Earth is currently experiencing is climate change brought on by human activity. Although human activities may exterminate some species from the world, the planet will undoubtedly recover and return to its natural balance as it has for millions of years. However, the sun will ultimately wipe out Earth, as predicted by scientists. The Sun will lose its structural integrity and enlarge in volume as it ages and eventually runs out of the fuel that keeps it going—hydrogen—which will cause it to burn everything in its path, including life on Earth. In the end, the Sun would perish, leaving the Solar System permanently in the dark.

Which process uses clathrin in coated pits to bring substances into cells? mastering ohysion
The process uses clathrin in coated pits to bring substances into cells Receptor-mediated endocytosis.
In the process of clathrin-mediated endocytosis, clathrin-coated pits are specialized patches in the plasma membrane that concentrate receptors, bend to create an invagination, and bud out with their receptor cargo.
What is Receptor-mediated endocytosis?
Bulk quantities of particular molecules can enter a cell via a process known as receptor-mediated endocytosis after interacting with cell surface receptors. The cell surface membrane is folded inward and finally pinched off forming a vesicle within the cell, allowing the chemicals coupled to these receptors to enter the cell. The budding vesicle's coating, which is made up of structural proteins like clathrin, gives it a rounded shape.
Low-density lipoproteins (LDL cholesterol) are one type of receptor-mediated endocytosis that is well understood.

The effect of high blood ph (alkalosis) on the respiratory centers in the brain is/are?
Answer:
Whenever the blood's acid-base equilibrium is affected by increasing quantities of carbon dioxide, pulmonary alkalosis results. People who have fast, uncontrolled breathing regularly face it (hyperventilation). Treatments that reduce the chance of hyperventilation are a component of the therapy. Alkalosis leads to cerebral vasoconstriction, which as a result decreases the brain's processing power and likely contributes to misperceiving and misreading. Hyperventilation is a subsequent disease to respiratory alkalosis. The most common causes of hyperventilation include shocks like hypoxia, metabolic acidosis, discomfort, stress, or a rise in metabolic demand. The body mostly uses the lungs to make up for both acidosis and alkalosis. When we breathe, the lungs let a certain amount of carbon dioxide leave, which alters the overall alkalinity of our blood. Additionally, the kidneys contribute by regulating the release of bicarbonate ions.

Researchers claim that this mass extinction was brought about by newly arriving humans tipping the scales of power and competing with powerful predators like sabre-tooth cats in a study that was just published in the journal Bioscience. A long-lasting equilibrium was upset, which could be the reason why two-thirds of North America's huge mammals disappeared during this time. Ripple stated, "We think the evidence suggests that substantial ecosystem changes, leading to these domino consequences, can be induced either by removing or introducing a major predator.

What effect would substituting the atom in the circle with the atoms in the square (a) have on the chemical properties of the resulting molecule?
The correct answer is option f) Both a and c.
We know that the formation of the carbocation intermediate is the rate-limiting step in an SN1 reaction. The rate of this phase, and hence the rate of the total substitution reaction, is determined by the activation energy for the process in which the link between the carbon and the leaving group breaks and a carbocation is formed. According to Hammond's postulate, the faster this first bond-breaking event occurs, the more stable the carbocation intermediate is. In other words, the stability of the resulting carbocation intermediate greatly influences the chance that a nucleophilic substitution process would occur through a dissociative SN1 mechanism.
A carbocation is a positively charged entity that has very few electrons, thus anything that adds electron density to the area of electron poverty will help stabilize it. However, an electron-withdrawing group will destabilize a carbocation.
Alkyl groups, such as methyl, ethyl, and similar compounds, are weak electron-donor groups that stabilize adjacent carbocations. This means that more substituted carbocations are often more stable; for example, a tert-butyl carbocation is more stable than an isopropyl carbocation. Since methyl carbocations are even less stable than primary carbocations, they are rarely seen as reaction intermediates.
Additionally, adding methyl groups as new substituents to a molecule often makes it more lipophilic and less soluble in water. Therefore, it decreases solubility.
Therefore, if the H-atom in the ethane is replaced by the methyl group, then the resultant molecule has the following effects:
