In response to the pancreatic hormones insulin and glucagon, the liver helps maintain blood glucose levels. Glucose enters the liver after a meal, and blood glucose levels rise. This excess glucose is handled by glycogenesis, which occurs when the liver converts glucose into glycogen for storage.
What is blood glucose?Glycemia is the concentration of glucose in the blood of humans or other animals. It is also known as blood sugar level, blood sugar concentration, or blood glucose level. A 70 kg person's blood contains approximately 4 grams of glucose, a simple sugar, at all times. A fasting blood sugar level of 99 mg/dL or less is considered normal, 100 to 125 mg/dL indicates prediabetes, and 126 mg/dL or higher indicates diabetes. The main sugar found in your blood is blood sugar, also known as glucose. It is the primary source of energy in your body and is derived from the food you eat. Your blood transports glucose to all of your body's cells, where it is used for energy. Diabetes is a disorder in which your blood sugar stations stand too elevated.To learn more about glycogen, refer to:

The excess glucose exists dealt with by glycogenesis in which the liver transforms glucose into glycogen for storage.
What role does the liver have in maintaining blood glucose?By converting glycogen into glucose, a process understood as glycogenolysis, the liver produces sugar or glucose. By gathering amino acids, waste materials, and lipid byproducts, the liver can also produce the glucose or sugar that is required. Glucose 6-phosphatase catalyzes the buffering effect of liver glycogen to maintain blood glucose levels. Glycogenolysis in muscles converts glucose 6-phosphate into glycolysis without wasting any adenosine triphosphate (ATP), as this enzyme is exclusively found in the liver.By balancing the uptake and storage of glucose through glycogenesis with the release of glucose through glycogenolysis and gluconeogenesis, the liver plays a crucial part in this process. The numerous substrate cycles in the main metabolic pathways of the liver are crucial in controlling the generation of glucose.The excess glucose exists dealt with by glycogenesis in which the liver transforms glucose into glycogen for storage.

The Loch Raven Reservoir supports a variety of organisms at all times of the year. There is an algal bloom this year. How would the environment be expected to change?
It is expected that the algal bloom in the Loch Raven Reservoir would change by decreasing the amount of available biomass.
What is the direct consequence of an algal bloom?The direct consequence of an algal bloom is an increase in the amount of available oxygen in the aquatic system and a drastic reduction in the light that enters into this ecosystem, which reduces the amount of biomass because plants are unable to produce photosynthesis.
Therefore, we can conclude that the consequence of an algal bloom is a decrease in the biomass that supports the trophic chain in this aquatic ecosystem.

a home made protocol for animal tissue DNA extraction?
DNA (deoxyribonucleic acid) is the hereditary material in almost all living organisms. Most DNA is located in the nucleus.
For extraction of DNA we need 500 ml water,91% Isopropyl Alcohol (rubbing alcohol),Dishwashing liquid, Salt, Food coloring (dark colors recommended),3 clear plastic cups
Steps include Pour 500ml water in a plastic cup
2. Add one tablespoon of salt to the water
3.dissolved the salt completely
Transfer 2 tablespoons of salt water in a clear plastic cup
2. Vigorously trill the salt water
3. Spit salt water back into the same cup
When you trill the salt water, cheek cells will come out. Add 1ml of clear dishwashing soap to the salt .It will break open the cheek cells and their nuclei walls and this causes the DNA to be released into the salt water.
1. Pour 100 ml isopropyl alcohol plastic cup.
2. Add 3 drops of food coloring, and isopropyl alcohol in a separate clear plastic cup.
2. Add 3 drops of food coloring, mix them well
DNA is insoluble in isopropyl alcohol so it will promotes the clustering of the DNA, making them visible.

True or False: Earth contains many different cycles thatinteract with each other and they move through Earth'sdifferent spheres.
Earth's ecosystem can be divided into 4 spheres, which are the atmosphere, the biosphere, the hydrosphere, and the geosphere. These spheres interact with each other and a change in one of them may cause a change in the other three spheres.
Within the ecosystem, the substances, such as water, carbon, oxygen, and nitrogen, undergo biochemical cycles. Through this cycle, the substances revolve through all spheres and are distributed throughout the whole ecosystem.
The statement is therefore TRUE.

During the carbon cycle, organic matter can be used in multiple ways by different organisms, although, this chemical compound also can be buried underground and converted into peat, coal, oil, or gas deposits. This is possible due to organisms can store this material in their structures to grow, and eventually, when they decay, for example, when a tree or an animal dies, it begins to form part of the soil in which they were before. This is the reason why currently we can extract oil from underground sinks, because of those biggest organisms that lived millions of years ago, such as the dinosaurs and ancient plants.

Many white blood cells can't divide and they have the ability to reproduce on their own.
How do white blood cells reproduce?White blood cells are not similar to other types of cells that are present in our body. They act like single-cell organisms which can move on their own and can feed on other cells and bacteria. Many types of white blood cells can't reproduce on their own so they are produced in the bone marrow. In a person that has normal bone marrow, the number of white blood cells can double within hours. It is a type of blood cell that is produced in the bone marrow and found in the blood lymph tissue. White blood cells are part of the immune system of our body.

Answer: Muscle contraction occurs when the thin actin and thick myosin filaments slide past each other. It is generally assumed that this process is driven by cross-bridges which extend from the myosin filaments and cyclically interact with the actin filaments as ATP is hydrolysed.
Explanation: and this is what happens: The sliding of protein filaments is responsible for muscle contraction. When a motor neuron stimulates a muscle fiber, overlapping thick and thin filaments slide along one another and sarcomeres shorten. The combined shortening of many sarcomeres in many muscle fibers results in contraction of the whole muscle.
