Which system is most dependent on a normal atmospheric pressure?

The philodendron plant would switch to an anaerobic metabolism, using its stored sugars to produce energy in the absence of light. Additionally, the lack of light may cause changes in the plant's phytochrome system, adjusting its physiological activities according to the perceived day/night cycle.

A philodendron plant placed in complete darkness for an extended period while still alive would have switched its metabolism to an anaerobic state. Under normal light conditions, plants utilize photosynthesis to produce sugars and oxygen from carbon dioxide and water. However, in the absence of light, photosynthesis cannot occur, and the plant subsequently switches to anaerobic metabolism, also known as respiration. This process doesn't require light, but instead makes use of the stored sugars in the plant and oxygen to produce energy. It's important to note that while the plant can survive for a while in a darkness-induced dormant state by burning these sugars for energy, prolonged darkness will put the plant at risk as it runs out of sugar supplies without the ability to photosynthesize and generate more.

Furthermore, the decreased availability of light may trigger a shift in the plant's internal processes such as its phytochrome system. Many plants use this system to discern the day/night cycle and adjust their physiology accordingly. It works based on the ratio of two forms of phytochrome: the active Pfr form and the inactive Pr form. In darkness, the active Pfr form slowly reverts back to the inactive Pr form, and if the darkness prolongs, all of the Pfr form may revert. If the plant is in a dormant state, this could possibly indicate winter and the plant will remain dormant until light conditions improve once again. Understanding these processes reflects the sophisticated use of light plants have in order to adapt to their environmental conditions.

Answer:

0.1%

Explanation:

The original energy of the sun is only absorbed by us humans when we feed on the organisms that are in the food chain and are called producers. Basically, the producers are the plants, which make photosynthesis and directly absorb the sun's energy.

In short, we can say that we only absorb energy from the sun when we eat plants. In the case of the hamburger, the sun's energy is passed to us through lettuce, tomato and onion (if your hamburger has these ingredients) which will give us about 0.1% of the sun's original energy.

Explanation:

Enzymes are the biological proteinous molecules that accelerate the metabolic and chemical processes of the body. Lipids break into fatty acids by the lipase enzyme.

Lipase enzymes are types of enzymes found in the body that splits the lipids into fatty acids and glycerol, which are the smaller units of triglycerides as the lipase enzymes are digestive and break the large biomolecule into its monomeric units. They play a vital role in lipid transportation.

The proteinous nature of enzymes denatures them at high temperatures and heat. The denatured lipase enzyme will become inactive and will not be able to bind to lipids which will decrease the rate of lipid metabolism in the body.

Therefore, the correct blanks are fatty acids and a decrease in the rate of lipid breakdown.

Final answer:

The term 'beriberi' refers to a deficiency condition caused by a lack of thiamine (vitamin B-1), leading to symptoms affecting the nervous and cardiovascular systems, potentially fatal if untreated. It commonly arose from diets reliant on polished white rice, which lacks thiamine. This condition highlights the importance of vitamins in human nutrition.

Explanation:

The diagnostic term beriberi refers to a medical condition that is caused by the lack of thiamine (part of B complex, specifically B-1) in the diet. Beriberi showcases various symptoms including loss of appetite (anorexia), polyneuritis (defects of nervous system), edema, cardio-vascular changes, weakness, muscular atrophy, headache, insomnia, and gastro-intestinal disorders. It can assume four forms: Dry Beriberi, where nervous symptoms prevail; Wet Beriberi, associated with edema; Acute Pernicious Beriberi, affecting the heart; and Mixed Beriberi, which combines symptoms of the other types. Infantile Beriberi is another form seen in breastfed children with thiamine-deficient mothers' milk.

Thiamine is essential for every cell, notably affecting respiration and metabolic processes. Deficiency may result in conditions like Korsakoff's syndrome, optic neuropathy, and can have a potentially fatal outcome if untreated. Causes of thiamine deficiency include poor nutrition, consumption of foods with thiaminase, chronic alcoholism, and various chronic diseases.

Enzymes hasten chemical reactions by lowering their activation energy. They do this by forming a unique complex with the substrate in a 'lock and key' manner. This complex helps to break the bonds of the substrate more quickly, effectively catalyzing the reaction.

Enzymes catalyze chemical reactions by reducing the activation energy needed for the reaction to occur. They achieve this through a mechanism called 'enzyme-substrate complex.' An enzyme has an active site which is a unique and specific shape, where the reactant, known as the substrate, fits like a lock and key. When the substrate binds to the enzyme's active site, it forms an enzyme-substrate complex. This complex helps to break the reactants’ bonds, therefore transforming the substrate into a product at a faster rate than it would have without the enzyme. Some enzymes might also go through a process called induced fit, where the enzyme changes shape slightly to better accommodate the substrate.

The right answer is She was measuring a rate of change.

Yeasts use respiration in an aerobic environment (presence of oxygen). This metabolism is used to produce molecules of ATP (adenosine triphosphate), a source of energy in the cell. Cellular respiration takes place in 3 main stages: glycolysis, Krebs cycle and the electron transport chain, linked to oxidative phosphorylation.

The balance equation of cellular respiration is:

6 O2 + C6H12O6 ==> 6 H2O + 36 ATP + 6 CO2

The rate of change makes it possible to study, as a percentage, the evolution of the value of a variable over a given period. For that, it is necessary to calculate the absolute variation, that is to say to make the difference between the value of arrival and the starting value, that one divides by the starting value, the whole multiplied by 100.

Explanation:

Glycerol and glycogen differ structurally and functionally; glycerol is involved in lipid metabolism as a component of fats, while glycogen, a highly branched polysaccharide of glucose, serves as the main energy storage form in animals.

The key difference between glycerol and glycogen lies in their structure and function within biological systems. Glycerol is a simple polyol compound involved primarily as a backbone in the formation of triglycerides and phospholipids in lipid metabolism. Conversely, glycogen, a highly branched polysaccharide made up of glucose units, serves as the main form of stored energy in animals, including humans. Glycogen's structure allows for rapid mobilization into glucose to meet the body's energy needs, especially during physical activity or when glucose levels in the blood are low. Glycerol, on the other hand, plays a crucial role in storing energy but in a different context, as part of fat molecules. Glycogen is synthesized and stored mainly in the liver and muscle tissues and is crucial for maintaining blood sugar levels and providing energy during exercise. Its structure, which includes branches occurring about every 8-10 residues, makes it denser and more readily accessible as an energy source than its plant counterpart, starch, which is less branched.

Monte was born with cataracts. he had surgery when he was 30 years old, which restored his sight. After his surgery it's important to protect eyes from UV exposure, and each individual might respond differently after the operation.

Monte, who was born with cataracts, underwent surgery to restore his sight at age 30. Cataracts, or clouding in the eye's lens, are a cause of diminished vision. A surgery is performed to replace the cloudy lens with a plastic one, and the success rate is generally high. Nearsightedness, farsightedness, and astigmatism can usually be corrected to produce normal distant vision in more than 90% of the patients.

There could be a few implications after undergoing such a surgery. There might be changes to the cornea and the lens' ability to focus properly, and the eyeball might enhance with age, causing images to focus in front of the retina. At times, repeated exposure to UV-B might lead to cataract formation, which is why it is important to protect the eyes against UV exposure.

Answer: High Bond Dissociation Energy

Explanation: A network solid refers to a solid compound (chemical compound) in which the atoms within the compound are bonded to each other by the covalent bond, maintaining a network of strong bonding. Covalent bonding is the strongest of all the bonding types.

In order to break a compound made up of covalent bond, a huge amount of energy is required which is known as the bond dissociation energy. This energy required to break the bond depends upon the strength of the covalent bond between the atoms.

Melting a network solid requires supplying enough energy to overcome the strong bonds within the solid.

In order to melt a network solid, such as a metal or covalent network solid, a sufficient amount of thermal energy is required to overcome the strong bonds within the solid. The melting point of a network solid is typically high due to the strength of these bonds. For example, in metals, the metallic bonds between the positively charged metal ions and the delocalized electrons require a lot of energy to break.

Another example is diamond, a covalent network solid made up of carbon atoms. Each carbon atom forms strong covalent bonds with four other carbon atoms, resulting in a rigid lattice structure. Melting diamond requires breaking these strong covalent bonds. This is why diamond has a high melting point.

Overall, the key requirement for melting a network solid is supplying enough energy to overcome the strong bonds within the solid.
