Most students have trouble with understand that HCl and Bile are not enzymes. They do allow for structural changes of the substrate, but they do not change the chemical breakdown of the substrate (breaking bonds. Describe your experience: 1.

Most students have trouble with understand that HCl and Bile are not enzymes. They do allow for structural changes of the substrate, but they do not change chemically breakdown the substate (breaking bonds)
Bile salt is a fat emulsifier.It has an hydrophobic end which points towards lipids and hydrophilic ends towards water.With this arrangement, the structure of fatty acid is modified in such a way that the lipid is well distributed and scattered in water.However, the chemical bonds in the lipids are not affected by the bile salts, because, bile did not breakdown the chemical bonds in lipids to form new compound, its only changes the food physical structure for easy digestion.
Describe your experience:
How comfortable do you feel about the statement that was just made?
What is a catalyst? Do you think that HCl and Bile are catalysts? Explain.
Using your own example, make an analogy explaining, to an 8-year-old, the concept of how a chemical will cause mechanical breakdown of a substance but not a chemical breakdown
Answer:
1.The statement means that,HCL and bile, which change the pH nature of the digesting food, and emulsify the digesting food respectively, only allow for structural changes in these food materials,but do not break or make new bonds between the components of the food substances.Therefore they do not formed new substances, but rather modified the food substances, no chemical reaction occurs but their effects only aids the process of digestion.
When a substances increases or speed up the rate of organic chemical reactions, but do not undergo any permanent changes in it chemical structure, in the course of catalysis, the substance is called a catalyst.
During digestion, HCL activates precursor pepsinogen to enzyme pepsin , which aids protein digestion in the stomach. HCL is not a catalyst,But acts to aid the action of an enzyme , by activating its precursor, for digestion to take place,The acid does not form a new compound.
Bile is an emulsifier , which aids the digestion of lipids by forming to tiny globules for easy digestion. It does not form a new product, but rather modified the existing product for easy digestion.

Consider this animal cell. The organelles in an animal cell are labeled. Part A is a structure with stacked membranes, part E represents small dots on the nucleolus, part F is a network of hollow tubes, flattened sheets, and round sacs, and part G is a bean-shaped structure with folding inside. Which organelle is responsible for producing the energy for cellular processes? organelle A organelle E organelle F organelle G
Answer:
G is a bean-shaped structure with folding inside
Explanation:
The Bean shape structure is the shape of Mitochondria, therefore it is the organelle of cellular respiration.
Kreb's Cycle and oxiadative phosphorylation are the major stages of of Cellular respiration which takes place in the mitochondria.
Cellular respiration is the process of extracting the energy as ATPs contained in foods(glucose, fatty acids, Aa) by combining them with oxygen.
Electron transport chains generate the energy for pumping protons to generate the energy, for ATPs synthesis, by enzyme ATPase synthases.

condensation and evaporation are examples of an interaction between:
A: none of these
B:Atmosphere and Lithosphere
C: hydrosphere and lithosphere
D: atmosphere and hydrosphere
This is urgent!!!!
Answer:
I would say D. atmosphere and hydrosphere
Explanation:
Because hydrosphere means water, and the atmosphere is where the water is evaporated to, and then condensed into rain.
During evaporation, liquid water converts to vapours into the atmosphere and during condensation, vapours are converted into liquid water. So, the correct option is D.
What are evaporation and condensation?
Evaporation is a process in which the surface of a liquid is converted to vapours. This process takes place at a temperature lower than the boiling point of the liquid.
Unlike boiling, evaporation is a surface process, which means only the top layer of the liquid is converted into vapours. While boiling is a bulk process.
This is an important process for the maintenance of the water cycle as most of the evaporation happens through oceans and rivers etc. This contributes to humidity in the atmosphere and ultimately results in rain.
Condensation is the opposite of evaporation in which the vapours turn back to liquid. This happens either because of a drop in temperature or increased vapour pressure.
In the water cycle when the vapour pressure of the atmosphere increases due to the high amount of water vapours, there is the formation of clouds which causes rainfall.
Hence, atmosphere and hydrosphere interactions make the process of condensation and evaporation possible.
Therefore correct option is D.

Scientists have been studying threats to coral reefs. The percent of reefs affected by various threats are shown in the figure below. A future global temperature increase may affect all categories on the figure. Predict which category would change the most from global temperature increases and propose a testable question that scientists could study.
a. The biggest effect will be on the far right column that includes thermal stress with a greater percentage of reefs falling into the low and medium threat categories. Scientists could test whether reefs that have greater fishing risk also have greater thermal risk.
b. The biggest effect will be on the far right column that includes thermal stress, with a greater percentage of reefs falling into the high and very high threat categories. Scientists could test whether reefs that have greater temperature changes have greater increases in watershed-based pollution.
c. The biggest effect will be on the far left column that includes fishing, with a greater percentage of reefs falling into the high and very high threat categories. Scientists could test whether increased fishing causes increased marine-based pollution.
d. The biggest effect will be on the far left column that includes fishing, with a greater percentage of reefs falling into the low and medium threat categories. Scientists could test whether reefs that have greater temperature changes have greater increases in fishing threats.
Answer:
It's B
Explanation:
Temperature rise will eventually end up putting coral reefs into the high threat categories, not fishing and DEFFINITELY not lowering their "risk" factor.
Coral reefs are the organisms of the aquatic ecosystem. The column includes the thermal stress that will be affected the most as the reefs fall into high and very high threats are huge. Thus, option B is correct.
What is the effect of thermal stress on coral reefs?Due to an increase in pollution and global warming, the oceans have heated up, which results in thermal stress and leads to coral bleaching and threat to the coral reefs.
The percentage of the very highly threatened, highly threatened, slightly threatened, and threatened reefs are seen majorly due to the thermal stress. Thermal stress is in increases amount due to oceanic warm-ups.
The thermal stress due to increased carbon dioxide activities and acidity leads to coral bleaching causes the destruction of the reefs and their endangerment.
Therefore, option B. the far right column labeled thermal stress has the biggest effect on the coral reefs.
