During the Calvin cycle, carbon dioxide is reduced to drive the formation of sugars.

During the process of photosynthesis, a set of chemical reaction that occurs in the chloroplast is known as the Calvin cycle, which is light independent.

Photosynthesis reaction can be divided into two stages that are the light reaction and the Calvin cycle, in the first stage light energy converted to the chemical energy and the second stage use the products of light reaction to produce sugar.

Explanation:

With the advent of industrialization, several trees have been cut at an alarming rate for raw materials and various other purposes. This felling of trees can be regulated by selective cutting, clear-cutting and shelterwood cutting.

Forest fires are one of the common causes of loss of forests. Sometimes the forest land is set on fire to make the land available for commercial purposes. Once cleared, there can be no vegetation. Natural forest fires are also responsible for the destruction of huge forest covers. Latest fire fighting techniques should be adopted to conserve the forest. However, forest fires are an important part of the ecosystem and it helps replenish nutrients in the soil from dead and decaying matter.

More trees should be planted to increase the forest cover. Trees should be selected according to the geographical conditions of a particular region and proper care should be taken during the growth of trees.

Prevention of exploitation of forestry and forest products is necessary for the conservation of forest.

The existing forests should be protected from diseases by spraying chemicals, antibiotics or development of pest-resistant strains of trees.

The activity of pepsin would gradually decreases when it is exposed to higher pH in the small intestine. This is because in higher pH the enzyme pepsin denatures.

The role of Pepsin in the stomach is determined by the fact that it serves to digest proteins found in ingested food. The Gastric chief cells typically secrete pepsin as an inactive zymogen called pepsinogen.

Parietal cells within the stomach lining effectively secrete hydrochloric acid that ultimately decreases the pH of the stomach. A low pH (1.5 to 2) activates pepsin.

It is thought that the role of pepsin is better played in the pH lies between 1.5-2. But when pepsin enters the region of the small intestine, the pH gradually increases and reaches 8. At this, the activity of pepsin is inhibited due to its denaturation.

Therefore, the activity of pepsin would gradually decrease when it is exposed to higher pH in the small intestine. This is because in higher pH the enzyme pepsin denatures.

The Great Red Spot, a permanent region of high pressure in Jupiter's atmosphere, is responsible for producing the largest anticyclonic storm in the Solar System. Thus, option D is correct.

In Jupiter's atmosphere, there is a huge, rotating storm known as the Great Red Spot. It is similar to an Earthly hurricane, but considerably bigger.

The Great Red Spot on Jupiter is larger than Earth by more than two times! Within this storm, winds can gust as high as 270 miles per hour (ca. 435 km/h).

When astronomers first focused their telescopes on Jupiter in the 17th century, they discovered a striking reddish patch on the massive planet. More than 300 years later, the Great Red Spot is still visible in Jupiter's atmosphere. It is now understood to be a big storm that is rotating like a cyclone.

Answer:

1.) RNA polymerase find promotor

2.) RNA polymerase unwinds strand

3.) RNA polymerase adds new nucleotides

4.) RNA polymerase reaches termination site

5.) Transcript is released

The correct order is 1. RNA polymerase unwinds the strand, 2. RNA polymerase finds promoter, 3. RNA polymerase adds new nucleotides, 4. The transcript is released, 5. RNA polymerase reaches the termination site.

The process of transcription involves the synthesis of RNA from a DNA template.

RNA polymerase unwinds strand: RNA polymerase recognizes the DNA strand that needs to be transcribed and unwinds the double helix, separating the two DNA strands.

RNA polymerase finds promoter: RNA polymerase searches for and binds to a specific DNA sequence called the promoter, which marks the starting point for transcription.

RNA polymerase adds new nucleotides: Once bound to the promoter, RNA polymerase begins moving along the DNA strand, reading the template strand and adding complementary RNA nucleotides. This process is known as elongation.

The transcript is released: As RNA polymerase moves along the DNA template, it continues adding nucleotides to the growing RNA molecule. Eventually, it reaches a termination site on the DNA, signaling the end of the gene or region being transcribed. At this point, the RNA polymerase releases the completed RNA transcript.

RNA polymerase reaches the termination site: The termination site is a specific DNA sequence that signals the end of transcription. Once RNA polymerase reaches this site, it detaches from the DNA template, and the RNA transcript is released.

Thus, the correct order is 1. RNA polymerase unwinds the strand, 2. RNA polymerase finds promoter, 3. RNA polymerase adds new nucleotides, 4. The transcript is released, 5. RNA polymerase reaches the termination site.

they would compare amino acid sequences to see how alike the DNA of the two species is to see how similar/related they are to one another

Explanation:

They would compare amino acid sequences to see how alike the DNA of the two species is to see how similar/related they are to one another.

The evolution of interactions between species dates back to the dawn of time. Little microorganisms in water were the first organisms to be produced on land. Amphibians started to evolve over time.

Old World monkeys were the first to diverge from the primary root of the primate family tree approximately 25–30 million years ago. The earliest relatives of modern humans diverged from their forebears about 6 million years ago, starting the evolutionary tree that produced many humanoid and ape species, including the Ardipithecus family.

Australopithecus afarensis, Homo habilis, and many others. Homo erectus eventually evolved between 1.5 and 2 million years ago.

anaerobic respiration takes place when you demand your muscles to do vigorous work. normally, aerobic respiration takes place but when energy is needed immediately, anaerobic respiration takes place. during anaerobic respiration,the body produces lactic acid, which leads to the burning sensation. your lungs deliver oxygen to the muscles much slower than the rate you need, since you're putting your muscles through an extensive exercise, and this leads to muscle fatigue.

The correct sequence of the components in a reflex is the Receptor → Sensory neuron → Spinal cord → Motor neuron → Muscle.

So, in this order, the reflex arc comprises of sensor, sensory neuron, control center, motor neuron, and muscle

The spinal cord serves as the primary control center for reflex actions. The spinal cord serves as the junction point for thousands of reflex arcs. Any involuntary and spontaneous reaction is a reflex, and the neurological system mediates the response.

A sensory neuron delivers electrical signals to a relay neuron in the CNS's spinal cord. Sensory neurons are linked to motor neurons through relay neurons. A motor neuron transmits electrical signals.

Plant cells and cyanobacteria (also photosynthetic) obtain the ATP required to power their usual cellular functions from Cellular respiration.

Plant cells and cyanobacteria are photosynthetic creatures that can produce their nourishment through the process of photosynthesis. They use light energy to transform carbon dioxide and water into glucose and oxygen during this process. However, to fuel their usual cellular functions, including protein synthesis, DNA replication, and cell division, cells require a steady source of energy in the form of ATP.

Cellular respiration produces the ATP necessary for plant cells and cyanobacteria. While photosynthesis generates glucose and oxygen, cellular respiration breaks down glucose molecules to release energy as ATP. This occurs in the mitochondria of plant cells and cyanobacteria. Glycolysis, the Krebs cycle, and oxidative phosphorylation are the three steps of cellular respiration. The first stage, glycolysis, involves the breakdown of glucose molecules into pyruvate, which releases a tiny quantity of ATP.

Pyruvate is transformed into acetyl-CoA in the Krebs cycle, which then enters a loop of reactions that creates additional ATP and carbon dioxide. Finally, electrons from the Krebs cycle are passed via a series of protein complexes in the third stage, oxidative phosphorylation, to form a proton gradient across the mitochondrial membrane. This gradient is then used to drive the production of ATP.

While photosynthesis also produces ATP through light reactions, this ATP is primarily used to power the photosynthesis itself, rather than the regular cellular processes of the plant cell or cyanobacterium. Therefore, the correct answer to the question is Cellular respiration.

Polysaccharides that cannot be digested by human digestive enzymes and pass into the large intestine are called dietary fiber.

Dietary fiber is an essential part of a healthy diet and consists of two types: soluble fiber and insoluble fiber. Soluble fiber dissolves in water and forms a gel-like substance, which can help lower blood cholesterol and glucose levels. Insoluble fiber, on the other hand, does not dissolve in water and promotes the movement of material through the digestive system, thereby improving bowel function.

Answer:

1 Dna is transcribed into mRNA, which is translated by the ribosome to produce an amino acid chain.

Explanation:

The steps of the process are always from DNA to mRNA to amino acids. This is because DNA can't travel out of the nucleus. So, DNA must be converted to mRNA to travel out of the nucleus. Only mRNA can leave the nucleus. The m in mRNA stands for messenger, so think of mRNA as the messenger from DNA to amino acids. Then the mRNA must be converted to amino acids to produce a protein.

So, options 3 and 4 are eliminated.

The process of DNA to mRNA is called Transcription. The act of transcription is called transcribing.

The process of mRNA to amino acid is called translation. The act of translation is translating.
