Insulin lowers the blood-sugar levels in the body.
What are the functions of insulin?Insulin is a peptide hormone produced by beta cells of the pancreatic islets encoded in humans by the INS gene. It is considered to be the main anabolic hormone of the body.
After you eat, carbohydrates break down into glucose, a sugar that is the body's primary source of energy. Glucose then enters the bloodstream. The pancreas responds by producing insulin, which allows glucose to enter the body's cells to provide energy.
Insulin is a peptide hormone secreted by the β cells of the pancreatic islets of Langerhans and maintains normal blood glucose levels by facilitating cellular glucose uptake, regulating carbohydrate, lipid and protein metabolism.

Tay Sachs is a disease caused by a mutation in a gene that codes for an enzyme used to break down complex molecules. Patients that have Tay Sachs accumulate excessive fat in brain cells and nerve cells. Normal functioning of this cell structure results in the digestion and removal of harmful fat accumulations, old cell parts, and invaders. Due to a mutation, the enzyme needed to remove fat accumulations does not function. Based on this information, what cellular structure is not functioning properly?
Answers
Answer:
Based on the given information , the cellular structure , which don not function properly in Tay Sachs disease is Lysosomes
Explanation:
LYSOSOMES -: In many animal cells, a lysosome is a membrane-bound organelle. These are spherical vesicles containing hydrolytic enzymes that can break down many types of biomolecules. A lysosome, with both its membrane proteins and its lumenal proteins, has a particular composition. There are a number of enzymes in lysosomes, helping the cell to break down different biomolecules that it swallows, including peptides, nucleic acids, carbohydrates , and lipids (lysosomal lipase). For optimal function, the enzymes responsible for this hydrolysis need an acidic environment.
TAY SACHS DISEASE -: The autosomal recessive disorder Tay-Sachs is caused by mutations in both gene alleles (HEXA) on chromosome 15. HEXA codes for the enzyme β-hexosaminidase A alpha subunit. This enzyme is contained in organelles, lysosomes, which break down large molecules for the cell to recycle.
Normally, β-hexosaminidase A helps to degrade a lipid called ganglioside GM2, but the enzyme is absent or present only in very small amounts in Tay-Sachs individuals, enabling excessive accumulation of ganglioside GM2 in neurons. In the different types of Tay-Sachs, the progressive neurodegeneration seen depends on the speed and degree of accumulation of GM2 ganglioside, which in turn depends on the amount of functional β-hexosaminidase A present in the body.
Hence , the answer is lysosomes .

what are the photosynthesis and respiration reactions? (i need a short answer)
Answers
Answer:
Reactions to respiration is -Cellular respiration is the chemical reaction in which glucose and oxygen are turned into water, carbon dioxide, and energy (ATP). In this reaction, glucose and oxygen are reactants, while water, carbon dioxide, and energy (ATP) are products.The reaction to photosynthesis is -process of photosynthesis is commonly written as: 6CO2 + 6H2O → C6H12O6 + 6O2. This means that the reactants, six carbon dioxide molecules and six water molecules, are converted by light energy captured by chlorophyll (implied by the arrow) into a sugar molecule and six oxygen molecules, the products.
Explanation:
Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.

How are embryonic stem cells different from other types of stem cells?
Answers
The difference between embryonic stem cell and other types of stem cells are :
Embryonic stem cell replicate indefinitely Embryonic stem cell is pluripotentThere are about 200 different types of cells present in the human body and the embryonic stem cell is different from other adult cells because it has the ability to differentiate into the ( 3 ) primary germ layers ( i.e. pluripotency ) and also they can replicate indefinitely unlike other cells that can only replicate itself a limited number of times.
Hence we can conclude that the difference between embryonic stem cell and other types of stem cell are Embryonic stem cell replicate indefinitely and Embryonic stem cells are pluripotent.

The air pressure at City A is 1,018 mb, and the air pressure at City B is 980 mb. What will most likely occur due to the pressure gradient present between City A and City B?
Answers
Answer:
There are three main causes of change in population: births, deaths and imigration flow. The Coronavirus has affected two of these three factors. The death rate has increased substantially since the pandemic hit. In under 6 months, more than 200,000 people have died. This drastic number of deaths in such a short amount of time is bound to decrease the population of the United States by a considerable margin. Immigration flow has also halted since the beginning of the pandemic. Travel bans and the close monitoring of borders has ensured that the number of immigrants entering the United States has decresed greatly.
Most likely the pressure gradient present between City A and City B that is City A is 1,018 mb, and City B is 980 mb, will - The high-pressure system at City A will create winds that blow toward the low-pressure system at City B.
A force exerted on a surface by the air above it as gravity pulls it to Earth is called air pressure or atmospheric pressure. Atmospheric pressure is commonly measured with a barometer.
it determines wind and weather patterns across the globewinds move from high air pressure to low air pressureIt leads directly to wind and influences the speed and direction of that wind.Pressure differences or gradients also affect larger weather systems like storms.Thus, Most likely the pressure gradient present between City A and City B that is City A is 1,018 mb, and City B is 980 mb, will - The high-pressure system at City A will create winds that blow toward the low-pressure system at City B.
