Answer:
Only 10% of the mass and energy is transferred
Explanation:
In a food chain, organism at a certain trophic level, obtain nutrition and energy from organism lying at its preceding trophic level.
As per the rule of energy pyramid, a higher organism feeding on any low level organism in a given food chain obtain only 10% of the total energy. The remaining 90% of the energy remains with the organism to carry out its metabolic processes including decomposition or self destruction.

If trypsin were to be placed in an acidic environment, how would it function? How do you know?
Answer:
If trypsin is in an acidic environment, it will decrease its function, since its optimum pH is 8.
Explanation:
Trypsin is an enzyme responsible for break peptide bonds, thus hydrolyzing proteins into peptides and amino acids. This enzyme is secreted by the pancreas and poured into the duodenum —an alkaline environment— where it acts.
Since the optimal pH for trypsin to fulfill its function is 8, if the enzyme were placed in an acidic environment it would decrease its function. This is because enzymes work under specific pH and temperature conditions, and changes in these conditions affect enzymatic activity.

state three reasons for preventing food spoilage
Answer:
1) Refrigerate or freeze
If you freeze or refrigerate the food, the bacteria or whatever organism growth will slow down in the food by a Greta amount due to the coldness. Refrigerate might be a temporary food soteage for like a week or 2/ month max. While freezing will just freeeze the bacteria and mold on the food which can be stored up to 3- 12+ months even. But then again it will be most likely flavorless by the end or have no nutrients value. You can stores mik in the freezer for a while but its not recommended to taste, same for other thing syou usually see in the fridge, eggs/ vegetables/fruits/ milks/ yogurts/ etc.
2) No moisture, no water of any kind (drying in the sun or salted)
So every living thing we know of needs water. Including bacteria and mold. Without water, theres no place to thrive. No place to thrive means no bacteria and food is safe for a good amount of time. Dried foods can last a really long time, sure some types are really unpleasant but its edible. But you can’t techincally “dry” meat since it will be A whole nest for flies before it even reaches the halfway mark. You can slat it which will lessen he time but still really efficient. Salt absorbs water and breaks down any type of Stuff. Its like a mini acid.
3) Canned good and no air access (Pressurized/ controlled container)
This is done by putting all your favortie food in a metal container. With no air access, the bacteria or mold in the food already in can’t escape and new ones can’t get in. THe can then is boiled to a certain tempature where then the bacteria dies. Now the food can even be perishable stuff like meat (most common fishes), fruits and even a nice can of liquid soup. Nothin g can get in. Nothing can get out but nothing CAN get out becuase eveythign is dead. Canned food can last REALLY LONG, good for long term expeditions without a fire or food.
Answer:
Drying is one of the most ancient food preservation techniques, which reduces water activity sufficiently to prevent bacterial growth. Refrigeration preserves food by slowing down the growth and reproduction of microorganisms and the action of enzymes which cause food to rot
Explanation:
Define homeostasis. Explain how the human body would respond to having a higher than normal level of sugar in the bloodstream.
Answer:
The term "homeostasis" refers to a state of equilibrium. As well as MAINTAINING the organism's equilibrium.
Insulin levels in the body would rise. The pancreas releases glucagon to boost blood sugar levels when they fall. This equilibrium allows the cells to get enough energy while avoiding the nerve damage that can occur when blood sugar levels are constantly high.

the enzyme dna covalently links nucleotides to synthesize new dna strands together during dna replication. t or f
The assertion is true. During DNA replication, the enzyme DNA Polymerase covalently joins nucleotides to create new DNA strands.
Semi-conservatism applies to DNA replication. The double helix's strands serve as models for the creation of new, complementary strands. DNA polymerases, which require a template and a primer (beginning) and synthesise DNA in the 5' to 3' orientation, are the enzymes responsible for creating new DNA.
Only strands or primers of DNA or RNA that are base paired with the template can have nucleotides added to them by the DNA synthesis enzyme, DNA polymerase. The covalent binding of the incoming nucleotide to the primer requires the enzyme DNA polymerase.
Therefore, we can conclude that the proposition is accurate. During DNA replication, the enzyme DNA Polymerase covalently joins nucleotides to create new DNA strands.

Jordan's grandmother uses the juice from squeezed lemons to remove stains from his shirt. He hypothesizes that the juice is the only part of the lemon that is effective at removing the stains, because it’s an acid. Which two steps would help Jordan determine whether his hypothesis is scientifically supported?
He should test the acidity of different parts of the lemon, including the juice, pulp, and skin.
He should conduct an opinion poll of residents to see if they agree with his hypothesis.
He should make identical stains on T-shirts and see whether different parts of the lemon will remove the stain.
He should find literature on housekeeping websites that support the use of lemon juice at removing stains.
He should compare lemon juice with other acidic juices to see if they all remove stains.
1.He should assess the acidity of the lemon's juice, pulp, and skin, among other lemon-related parts. 2. He should try different lemon pieces to see if they can remove identical stains from T-shirts.
What brings on acidity?When the valve muscle just at lower end if your esophagus relaxes unexpectedly, acid reflux results, causing stomach acid to back into the esophagus. Together with other symptoms and indicators, this may result in heartburn. GERD can be brought on by frequent or ongoing reflux.
What counteracts acidity?To establish balance, add either sugar or fat to tame the sourness of an overly acidic food.

which of the cells exhibit 32 applies most clearly to the environment, uncertain environmental face by hbo
The cells that exhibit 32 apply most clearly to the environment, uncertain environmental face by HBO are the cells of the cerebellum and midbrain.
A human brain is divided into different parts such as the cerebrum, cerebellum, and brainstem. The cerebellum and midbrain are the two sections that are most affected by HBO (hyperbaric oxygen) therapy. When a patient is exposed to high levels of oxygen, the concentration of oxygen increases in the blood which then reaches the brain and triggers the cells to release antioxidants and growth factors.
These cells help the brain to regenerate and repair the damage caused by any injuries. The HBO treatment can cause oxidative stress, which can damage cell membranes, enzymes, and DNA, however, the cells of the cerebellum and midbrain exhibit the greatest protection against oxidative stress.
The oxidative stress causes these cells to produce more antioxidants, which neutralize the free radicals and protect the brain cells. Thus, these cells exhibit 32 applies most clearly to the environment, uncertain environmental face by HBO.
