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.

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.

Which of the following is NOT one of the major land biomes? a. tropical rain forest c. temperate grasslands b. temperate savanna d. temperate deciduous forest
Answers
Answer:
Temperate Savanna.
Explanation:
Savanna is not temperate, it is also called tropical grasslands, further supporting my answer. It is PART of the kinds of grasslands, So because it is a part, it is not a major Biome.
Temperate savanna is not the major land biomes.
What is Biomes?Some of the electrons in metallic atoms are held there quite loosely. As a result, they frequently lose electrons and generate cations. In contrast, most nonmetallic atoms have a stronger attraction to electrons than do metallic atoms, and as a result, they gain electrons to form anions.
As a result, when two atoms from a metallic and a nonmetallic element unite, the nonmetallic atoms usually tend to take one or more electrons from the metallic atoms and create ions.
One-third of the Earth is covered in forests, which are primarily made up of trees. A large portion of the terrestrial biodiversity of the planet, including insects, birds, and mammals, is found in forests.
Therefore, Temperate savanna is not the major land biomes.

C: 12 go into the reaction
O: 6 go into the reaction
This can be determined by simply looking at the formulas of each molecule and the individual components (multiplied by the number of molecules)
As for the number of (C2H4O) molecules made:
6(C2H4) + 3(O2) = ?(C2H4O)
You want the number of molecules coming out to be the same as the amount going in (ex. If 6 O go in, 6 must come out). Because you want 12 C, 24 H, and 6 O, you can look at the subscripts within the acetaldehyde formula and find a number that will get the two sides equal.
In this case, you can get 12, 24, and 6 by multiplying the 2 (C), 4 (H), and 1 (O) by six.
6(C2H4) + 3(O2) = 6(C2H4O)
6 molecules of C2H4O are made.
12: goes into reaction
6: goes into reaction

A pedigree chart is used to _______.
predict percentage of offspring with a trait
predict genotypic probabilities
track inherited traits through generations
identify the genotype of parents
Answers
A pedigree chart is used to track inherited traits through generations.
A pedigree chart is a visual tool that represents the inheritance patterns of specific traits or genetic conditions within a family. It helps to trace the occurrence of traits, diseases, or genetic conditions across multiple generations by depicting the relationships between individuals and their affected or unaffected status.
Pedigree charts are commonly used in genetics and genetic counseling to analyze patterns of inheritance, identify carriers of genetic disorders, determine the probability of passing on certain traits or diseases, and study the transmission of traits within families. By examining the patterns of inheritance in a pedigree chart, one can gain insights into the mode of inheritance, such as autosomal dominant, autosomal recessive, or X-linked inheritance, and make predictions about the likelihood of certain traits or conditions appearing in future generations.

What are ways to reduce electricity usage?There are several ways to reduce the amount of electricity used in your home. One of the most effective ways is to replace old appliances with new Energy Star certified ones. These appliances are designed to use less energy and can help reduce your energy bills. Another way to reduce electricity consumption is to unplug electronics when they are not in use. Even when electronics are turned off, they still draw power if they are plugged in. Additionally, using energy-efficient light bulbs and turning off lights when leaving a room can also help save electricity.
Making these changes can have a significant impact on climate change by reducing carbon emissions. The less energy we use, the fewer fossil fuels are burned to generate electricity, which in turn decreases the amount of greenhouse gases released into the atmosphere.
