difference between sustainable agriculture and organic agriculture?
Organic farming is focused on the inputs used in production while sustainable farming is focused on the physical treatment of the land .
Organic farming is agriculture that makes healthy food, healthy soils, healthy plants, and healthy environments a priority, along with crop productivity.
Sustainable agriculture relies solely on natural processes for input and recycles nutrients on-site to eliminate the use of non-renewable resources. The main goals of sustainable agriculture are environmental health, economic profitability, and social and economic equity. sustainable agriculture mainly focus to meet society's food and textile needs in the present without compromising the ability of future generations to meet their needs.

The Nucleus controls the cell division.
Nucleus- In terms of genomics, a nucleus is the organelle inside a cell that is membrane-enclosed and houses the chromosomes. The nuclear membrane has a variety of pores that enable the selective transit of specific molecules (such proteins & nucleic acids) to and from the nucleus.
Cell Division- The mechanism through which a cell, known as the parent cell, splits into two cells, known as daughter cells, is known as cell division. Everything inside a cell divides when it divides. The mitochondria also divide together with the chromosomes and nucleus.

What is the role of NADPH in CO₂ reduction?
A redox pathway is represented by the dark reactions. As CO2 is reduced to glucose, NADPH gets oxidized to NADP+.
NADPH does it lessen CO2?During the Calvin-Benson cycle, carbon dioxide from the atmosphere is transformed into glucose. Utilizing the electrons made accessible by the oxidation of NADPH, calls for the total reduction of CO2. So, a redox pathway is represented by the dark reactions. As CO2 is reduced to glucose, NADPH was oxidized to NADP+.
What function does NADPH perform?All organisms require nicotinamide adenine dinucleotide phosphate (NADPH) as an important electron donor because it supplies the reducing energy needed for anabolic processes and redox balance. NADPH homeostasis is controlled by a variety of signaling channels and various metabolic enzymes that change adaptively in cancer cells.
Does NADH lessen CO2?The equilibrium predicted per thermodynamic considerations, which is likewise attained from the formic acid side, is obtained during the enzyme-catalyzed CO2 reduction by NADH. The Michaelis constant with CO2 is around 40 mM, reflecting the enzyme's poor affinity for this substrate.

A scientist observes an increase in oxygen levels following a volcanic eruption. Explain the sequence of events that makes this possible and identify which of Earth’s spheres are being affected at each step. Your answer should include changes to at least two spheres.
Volcanic eruptions are the expulsion of magma and gases from the interior to the exterior of the Earth. They are caused by plate interaction in the crust and changes in magma and pressure in the mantle.
What are volcanic eruptions?
A volcanic eruption is an expulsion of material rising from the Earth's interior toward the surface. It is an event that occurs when hot magma generated in the Earth's interior rises along the volcano, together with gases that increase the pressure until it emerges to the exterior.
Volcanic eruptions are related to tectonic plate movements. These plates interact and produce new magma by melting solid material. These interactions produce changes in tectonic plates, magma movements, and pressure in the Earth's interior, which is directed to the cortex -the outermost layer-.
The elevated temperatures, and the increase in pressure and magma changes, make it rise toward the surface moving along the volcano until emerging to the exterior. This is how the Erth interior and exterior pressures are equilibrated again.
Let us remember that,
The crust is the most external layer placed upon the mantle and divided into many plates. This layer is part of the lithosphere.The mantle is the second layer of the Earth. It is composed of hot and dense rocky material capable of flowing. Convection currents occur in this layer, rising hot melted material from the deepest region and sinking cold solid material from the surface. This layer composes the mesosphere and the asthenosphere.
Volcanic eruptions increase gases concentration in the exterior, and is a natural cause of atmospheric pollution.

d. Sleep restores our brains and makes us feel good.
The statement that best defines sleep is: "Sleep is a naturally recurring state characterized by reduced or absent consciousness, relatively suspended sensory activity, and inactivity of nearly all voluntary muscles."
What is sleep?Sleep is a naturally recurring state of reduced consciousness and decreased sensory activity that occurs in most animals, including humans.
During sleep, the brain and body undergo complex physiological changes, including changes in brain waves, heart rate, breathing, and muscle activity.
This definition captures the essential features of sleep, which include reduced awareness and responsiveness to the environment, decreased muscle activity, and distinct patterns of brain activity.
While melatonin and adenosine are involved in regulating sleep, they do not fully explain the complex phenomenon of sleep. Similarly, while sleep can restore our brains and improve our mood, this is not a complete definition of sleep.

the end‑replication problem (telomere problem) exists in eukaryotic chromosomes and is characterized by the chromosomes shortening with each round of dna replication.
Each replication cycle results in an incomplete replication of the DNA near the extreme end of the chromosome, gradually shrinking the chromosome.
What is the root cause of the eukaryotic chromosome end replication problem?Eukaryotes have linear, rod-shaped chromosomes that have ends as opposed to bacteria, which have circular chromosomes. DNA replication is difficult as a result of these ends. Each replication cycle results in an incomplete replication of the DNA near the extreme end of the chromosome, gradually shrinking the chromosome.
What specifically is the replication issue at the telomere end?Telomeres shorten as a result of regular DNA polymerases' incomplete copying of linear DNA molecules during cell division. The end replication problem is the name given to this [6]. The process of resection and fill-in that occurs during the synthesis of the telomere leading-strand is mostly to blame for this.
