Explanation:

The bloodstream carries the glucose-a type of sugar produced from the digestion of carbohydrates and other foods-to provide energy to cells throughout the body. Unused glucose is stored mainly in the liver as glycogen.

Insulin, glucagon, and other hormone levels rise and fall to keep blood sugar in a normal range. Too little or too much of these hormones can cause blood sugar levels to fall too low (hypoglycemia) or rise too high (hyperglycemia).

Normally, blood glucose levels increase after you eat a meal. When blood sugar rises, cells in the pancreas release insulin, causing the body to absorb glucose from the blood and lowering the blood sugar level to normal. When blood sugar drops too low, the level of insulin declines and other cells in the pancreas release glucagon, which causes the liver to turn stored glycogen back into glucose and release it into the blood. This brings blood sugar levels to back up to normal.

q3.12. approximately how many watts does a 80,000 gram human at rest (about 175 lbs) generate from metabolic heat?

Answers

An 80,000-gram person produces 103.2 volts of power at rest, or watts.

CalculationWe now know that the average person typically produces about 80 volts at rest and that the average weight of the human population is roughly 62 kg, thus 80,000 grams will equal 80 kg in this case. So, 62 kg will generate 80 watts at rest. The result is 1.29 waltz, or roughly 80 divided by 62 for 1 kilogram. Hence, putting an 80 kilogram person into 1.29 volts will result in 103.2 volts of atestso. The answer to this is that an 80000-gram human will emit metabolic heat of about 103.2 volts. I truly hope you found this beneficial.

What are the subunits (monomers) of DNA and their function? O Monosaccharides that provide quick energy for the cell. O Lipids that store energy and provide insulation. O Proteins that provide the building blocks for the structures of organisms. O Nucleotides that store information.​

Answers

Answer:

Nucleotides that store information

Explanation:

Deoxyribonucleic acid, commonly known as DNA, is one of the two nucleic acid biomolecules found in living systems. DNA is a polymer made up of long chains of monomeric units called NUCLEOTIDES. Nucleotides consists of three major subunits or parts namely: phosphate group, nitrogenous base (A,T, G, C) and a five-carbon sugar (deoxyribose).

Nucleotides are responsible for the functional and structural characteristics of DNA, which is to store GENETIC INFORMATION in living cells.

how do the locations where photosynthesis occurs differ in prokaryotes and eukaryotes

Answers

Photosynthesis takes place on the folds in prokaryotes and in specialised organelles in eukaryotes. Prokaryotic cells don't have specific organelles or a remote nucleus.

What is photosynthesis?

Plants absorb water (H2O) and carbon dioxide (CO2) from the soil and atmosphere during photosynthesis. Water is oxidised, which means it loses electrons, while carbon dioxide is reduced, which means it receives electrons, inside the plant cell. Water is converted into oxygen and carbon dioxide into glucose as a result. After storing energy within the glucose molecules, the plant releases the oxygen back into the atmosphere.

Chloroplasts, which are tiny organelles found inside plant cells, are there to store solar energy. Chlorophyll, a light-absorbing pigment found in the thylakoid membranes of the chloroplast, is what gives plants their green hue.

why is the solute concentration (mosm) in the proximal tubule the same as in the blood

Answers

The solute concentration in the proximal tubule of the kidney is maintained at the same level as that of the blood by a process called tubular reabsorption.

As the blood flows through the glomerulus, a network of tiny blood vessels in the kidney, water and solutes are filtered out of the blood and into the proximal tubule.

However, the body needs to maintain a certain concentration of solutes in the blood for optimal function, so the kidney reabsorbs some of the filtered solutes back into the blood through the walls of the proximal tubule.

This reabsorption process ensures that the concentration of solutes in the blood remains constant, while excess water and waste products are excreted from the body.

The amount of solutes that are reabsorbed depends on the body's needs at that moment, and this process is regulated by various hormones and enzymes.

what is defined as an inorganic compound that dissociates into ions and is closely related to fluid balance?

Answers

Electrolytes are inorganic compounds that dissociate into ions and are closely related to fluid balance. The inorganic compound that dissociates into ions and is closely related to fluid balance is called an electrolyte.

Electrolytes are substances that, when dissolved in water or other solvents, dissociate into positively and negatively charged ions. These ions are essential for various physiological processes in the body, including maintaining proper fluid balance.

Electrolytes play a crucial role in regulating the distribution of water between different compartments of the body, such as intracellular and extracellular fluid compartments. They help maintain osmotic pressure, which is important for proper cellular function and hydration.

Common electrolytes include sodium (Na+), potassium (K+), calcium (Ca2+), magnesium (Mg2+), chloride (Cl-), bicarbonate (HCO3-), and phosphate (PO43-). Imbalances in electrolyte levels can lead to disruptions in fluid balance, affecting cellular function, nerve conduction, muscle contraction, and overall physiological homeostasis.

Therefore, maintaining adequate levels of electrolytes is vital for maintaining fluid balance and supporting proper bodily functions.

What determines the order of amino acids in a protein?A. The order of nucleotide bases within a geneB. Enzymes present at the ribosomesC. Amino acids available in cell cytoplasm

Answers

The order of nucleotide bases within a gene determines the order of amino acids in a protein

The order of amino acids in a protein is determined by the sequence of nucleotide bases within the gene that codes for that protein. This is because the genetic information encoded in DNA is transcribed into messenger RNA (mRNA), which is then translated into a sequence of amino acids during protein synthesis. The sequence of nucleotides in the DNA determines the sequence of bases in the mRNA, which in turn determines the sequence of amino acids in the protein. The process of translation occurs at the ribosomes, but the enzymes present at the ribosomes do not determine the order of amino acids in the protein. The availability of amino acids in the cell cytoplasm can affect the rate of protein synthesis, but it does not determine the order of amino acids in the protein.

What are the four main functions of a skeleton? ANSWER PLEASE, WILL GIVE BRAINLIEST!!!!!!, ASAP ASAP PLSSSSSSSSSSSSSSSS

Answers

Answer:

support, production of blood cells, storage of ions, and endocrine regulation. 


The four main functions of a skeleton:
Support the bodyProtect vital organsHelp the body moveMake blood cells

Support

Your body is supported by your skeleton, which also holds your internal organs in place. The body would be floppy, like a jellyfish, without bones. Your muscles and organs have a framework to connect, thanks to your bones. The vertebral column (backbone) is what keeps your body upright.


Protect

Because bones are strong and hard, they can protect vital internal organs from harm. For example:

Your skull protects your brain.Your rib cage protects your heart and lungs.Your backbone protects your spinal cord.

Move

Bones are attached to muscles. A bone will move as a result of a muscle pulling on it. The skeleton is flexible at joints like your knee. The body may move because of how bones move around joints.


Making blood cells

Your body has some hollow bones, such as the long ones in your arms and legs. A soft tissue called bone marrow is located in the middle of these bones. Red and white blood cells are created in the bone marrow. White blood cells are used to fight infection, whereas red blood cells are used to transport oxygen throughout the body.

After a forest fire, which type of organisms will begin secondary succession?
small shrubs
mature oaks
evergreens
wildflowers

Answers

After a fire, species start to recolonize an area, beginning the secondary succession process. The first species to colonize are usually fast growing herbaceous plants, such as conifers or ferns.

Small shrubs are the kind of organisms that start secondary succession after a forest fire. The correct option is A.

Thus, the term "secondary succession" describes the ecological recovery process that follows a disruption like a fire. Small shrubs have developed survival strategies that enable them to swiftly colonize damaged environments.

They have the capacity to emerge from subterranean structures once again or to create seeds that will take root in newly accessible sunshine and nutrients. Due to their quick growth and capacity to keep the soil stable, these shrubs facilitate the establishment and flourishing of other plant species.

Thus, the ideal selection is option A.

5. What are virus hoaxes? Why are the hoaxes sometimes more dangerous than an actual virus?

Answers

Answer:

An actual computer virus is a malicious software, often known as malware, that can harm a computer and its users.

Virus hoaxes are false or misleading information about viruses that circulate through various communication channels.

They can be more dangerous than actual viruses due to their ability to spread quickly, cause panic, and undermine effective public health measures.

Virus hoaxes are deceptive messages or claims that often exaggerate the severity or impact of a particular virus. They can be spread through social media, email chains, or word of mouth. These hoaxes may include misinformation about symptoms, transmission methods, or false remedies, leading people to take ineffective or even harmful actions.

What makes virus hoaxes particularly dangerous is their potential to create panic and misinformation at a rapid pace. The viral nature of social media and other communication platforms allows these hoaxes to reach a wide audience within a short period. As a result, people may make decisions based on false information, such as avoiding necessary medical treatment, taking unnecessary precautions, or spreading fear and misinformation to others.

Moreover, virus hoaxes can undermine public health efforts by diverting attention and resources from legitimate preventive measures. They can erode trust in healthcare authorities and disrupt the dissemination of accurate information, making it harder for individuals to make informed decisions and follow recommended guidelines.

This can have severe consequences, especially during outbreaks or pandemics, where timely and accurate information is crucial for public safety. Therefore, it is essential to verify the credibility of information and rely on trusted sources to mitigate the risks associated with virus hoaxes.
