ALS is characterized by the progressive degeneration of motor nerve cells in the brain (upper motor neurons) and spinal cord (lower motor neurons).
ALS (amyotrophic lateral sclerosis) causes loss of muscle control. ALS is often called Lou Gehrig's disease, after the baseball player who was diagnosed with it. ALS has no cure. Causes of ALS: Theoretical mechanisms of neurodegeneration 1 Oxidative stress Defective glutamate metabolism Mitochondrial dysfunction. This neuronal death causes loss of brain volume and disruption of sodium, calcium, and potassium ion channels, which in turn alters neuronal conductance. The disorder is named for its underlying pathophysiology, and "amyotrophy" refers to the atrophy of muscle fibers, which are denervated as the corresponding anterior horn cells degenerate.

During fermentation, most of the pyruvate produced during glycolysis is used to convert nadh to?.
Reduced NADH from glycolysis is utilized during fermentation to decrease pyruvate. Reduced pyruvate is converted to lactate or ethanol.
How does fermentation affect NADH?In the course of fermentation, the NADH + H+ produced during glycolysis will be recycled back into NAD+, allowing glycolysis to proceed. NAD+ is converted into NADH + H+ during the glycolysis process. Glycolysis won't be able to proceed if NAD+ isn't present.
What function does NADH, a byproduct of glycolysis, serve?NADH helps with the oxidation of glucose by contributing to oxidation in cell processes like glycolysis. In the process of aerobic cellular respiration, the TCA cycle provides the energy stored in this reduced coenzyme NADH, which fuels the electron transport activity in the membranes of mitochondria.

which of the following does not lead to an increase in phytoplankton reproduction? a. increased nutrient availability b. increased sunlight c. increased oxygen levels d. increased levels of carbon dioxide
Option (C) is correct i.e. increased oxygen levels does not lead to an increase in phytoplankton reproduction.
The autotrophic (self-feeding) phytoplankton constituents are a crucial component of freshwater and ocean ecosystems. Photosynthesis is how land plants, like trees and phytoplankton, get their energy. Phytoplankton lives on the highly lit surface layers (euphotic zone) of seas and lakes because they need sunlight to survive. Phytoplankton is more extensively distributed, less seasonal, and has noticeably higher turnover rates than trees as compared to terrestrial plants (days versus decades). As a result, phytoplankton reacts to climatic changes quickly and widely. Both freshwater and marine food webs are based on phytoplankton, which is also essential to the global carbon cycle. They generate at least 50% of the world's oxygen production and nearly 50% of the photosynthetic activity despite making up only about 1% of all plants' biomass. With photosynthesizing bacteria, algae that resemble plants, and coccolithophores with armor-like plates, phytoplankton is immensely diverse. The dinoflagellates, cyanobacteria, and diatoms are some of the most prominent phytoplankton species.

based on whay you know about neuroendocrinology and stress, why is it common for peoopple t stress eat in respose to hallehgning systems
Based on neuroendocrinology and stress we observe that when you are stressed, your adrenal glands secrete hormone called cortisol. You might indeed observe an increase in appetite and an urge to eat sugary, salty, or fatty foods when this occurs.
Neuroendocrinology is the result of the relationship between the nervous system and the endocrine system, or how the brain regulates hormonal activity in the body. Thus, neuroendocrinology is the study of hormone-brain interactions, specifically how hormonal changes affect behavior.
Cortisol is a glucocorticoid hormone produced and released by your adrenal glands. Hormones are chemicals that help your body coordinate different functions by transporting signals through your blood to your organs, skin, muscles, and other tissues. These signals instruct your body regarding what to do and when. Cortisol is a steroid hormone produced and released by your adrenal glands, which are located on top of your kidneys. Cortisol influences several aspects of your body, primarily regulating your body's stress response.

a mixture of ddntps and dntps is used in sanger sequencing. which of the following statement is correct?
When added to a growing chain, dNTPs prevent DNA synthesis because they lack a hydroxyl group in the 3' position.
What is Sanger sequencing?
The "chain termination method," often known as Sanger sequencing, is a technique for figuring out the nucleotide sequence of DNA. The Sanger Sequence is a technique that was created in 1977 by two-time Nobel laureate Frederick Sanger and his colleagues.
The Sanger sequencing process consists of three key phases.
DNA SEQUENCE FOR ENDING CHAIN PCR
Chain-termination PCR is a unique form of PCR that uses the DNA sequence of interest as a template. While chain-termination PCR functions similarly to normal PCR, it differs significantly in that modified nucleotides (dNTPs) known as dideoxy ribonucleotides are added (ddNTPs).
ELECTROPHORESIS OF GEL TO SEPARATE SIZE
The second stage involves separating the chain-terminated oligonucleotides by size using gel electrophoresis. The oligonucleotides will be drawn toward the positive electrode on the other side of the gel in gel electrophoresis because DNA is negatively charged. DNA samples are placed into one end of a gel matrix and an electric current is applied.
DNA SEQUENCE DETERMINATION & GEL ANALYSIS
The final step consists of simply reading the gel to ascertain the input DNA sequence. Each terminal ddNTP will match a specific nucleotide in the original sequence as DNA polymerase only creates DNA in the 5' to 3' direction beginning at a supplied primer.
Hence, When added to a growing chain, dNTPs prevent DNA synthesis because they lack a hydroxyl group in the 3' position.

The problem of overpopulation is compounded by the fact that the global population is expected to continue to grow at a rapid rate in the coming decades. This is because the fertility rate in many countries remains high, while the mortality rate continues to decline due to advances in healthcare and nutrition.
In addition, the number of people living in cities is also increasing, which is putting strain on urban infrastructure and resources. This is leading to several problems such as air pollution, traffic congestion, water shortages, and overcrowding.
Finally, the large number of people on the planet has also had a significant environmental impact. The increasing demand for resources such as food, water, and energy is resulting in deforestation, habitat destruction, and climate change.

What is weathering?Weathering may be defined as the process of breaking down or dissolving rocks and minerals on Earth's surface. It involves the complete deterioration of rocks, soils, and minerals as well as wood and artificial materials through contact with water, atmospheric gases, and biological organisms.
Freeze-thaw weathering is the main type of weathering. In proceeding in a manner that during the day when temperatures are higher, the snow melts and water enters the cracks in the rock. When the temperature drops below 0°C the water in the crack freezes and expands by about 9%. This makes the crack larger.
The majority of abrasions heal without leaving any scars. However, the abrasions that extend into the dermis may result in scarring of the tissue upon healing. The most common mechanism of the formation of abrasion is due to friction against the epidermis, resulting in its denudation.
