1. Lactose takes years to break down on its own. But if exposed to the protein lactase, the reaction proceeds very quickly, while lactase itself remains unchanged. Lactase is an example of a(n) . 2. A(n) is a molecule that can bind to an enzyme and prevent the enzyme from working. There are two types: a(n) binds to the active site of the enzyme; a(n) binds elsewhere on the enzyme. 3. Enzymes speed up chemical reactions by lowering the , which allows the reaction to proceed much more quickly. 4. During an enzymatic reaction, a molecule of binds to the enzyme and is broken down into one or more molecules of , which are released. 5. The specific location within an enzyme molecule where the substrate binds is called the .
Answer:
1.) Lactase is an example of ENZYME.
2.)An INHIBITOR is a molecule that can bind to an enzyme and prevent the enzyme from working.
3.)Enzymes speed up chemical reactions by lowering the ACTIVATION ENERGY,
4.) a molecule of SUBSTRATE binds to the enzyme and is broken down into one or more molecules of PRODUCT which are released.
5.) The specific location within an enzyme molecule where the substrate binds is called the ACTIVE SITE.
Explanation:
An enzyme is defined as the substances that aids in the breaking down of complex food substances, taken in by animals, into simple, soluble and diffusible substances before they can be absorbed into the body. In the enzymatic reactions, a molecule of SUBSTRATE binds to the ACTIVE SITE of an enzyme and is broken down into one or more molecules of PRODUCT which are released.
There are different types of enzymes which are named according to the type of good they digest, these include:
--> Lactase: breaks down Lactose
--> proteases: breaks down proteins
--> Amylases: breaks down carbohydrate
Enzymes have the following characteristics:
--> They are proteins
--> They are specific in action. For example Lactase can only act on lactose.
--> They can be inactivated by INHIBITORS.
--> They are sensitive to temperature
--> They speed up a reaction by lowering the ACTIVATION ENERGY
Why are third parties important in a political system?
Answer:
Third parties are important in a political system because they serve an important role in our political system by forcing major political parties to address new issues they might not have previously addressed very much. And third party candidates can also greatly impact an election by taking away votes from one of the major political party candidates.

Scientists found members of a plant species they did not recognize. They wanted to determine if the unknown species was related to one or more of four known species, A, B, C, and D. The relationship between species can be determined most accurately by comparing the results of gel electrophoresis of the DNA from different species. The chart below represents the results of gel electrophoresis of the DNA from the unknown plant species and the four known species.
Complete question:
Scientists found members of a plant species they did not recognize. They wanted to determine if the unknown species was related to one or more of four known species – A, B, C, D. The relationship between species can be determined by comparing the results of gel electrophoresis of the DNA from different species. The chart below represents the results of gel electrophoresis of the DNA from the unknown plant species and the four known species.
Which two known plant species is the unknown plant species most closely related to?
Answer:
Species C is the most closely related, followed by species D.
Explanation:
Gel electrophoresis technique is used to separate different fragments of DNI, RNA, and other macromolecules or proteins, concerning their size/weight and charge.
Gel electrophoresis of DNI lets us visualize how many different fragments of the molecule are present in a sample and how they differ from each other. The presence of fragments of the same size will be distinguished as a line named band. Each band represents many DNI fragments of similar size placed in the same position. The result of the gel electrophoresis will be different bands in different positions according to their sizes. The biggest ones will not migrate in the gel as much as the smallest ones.
In the exposed example we can assume that the most closely related species is C. The second most similar is species D.
The gel electrophoresis of the DNA from the unknown plant species resulted in five different bands, which means five types of fragments of different sizes.
Four of the five bands expressed by the unknown species coincide with the bands of species C. Species C only lack one band to be exactly the same.Species D coincides in three bands and lack two bands to be exactly the same as the unknown species. Species A only coincides in one band. Species B does not coincide in any band, meaning that this is the most different oneFor a better understanding, look at the attached files, where you will find the chart.

Heat and light on Earth are unevenly distributed because they cannot receive heat and light equally in all parts of the earth.
Answer:
True
Explanation:
The earth receives unequal amount of light energy and heat energy form the sun. There is variation in the solar energy at different parts of the world due to factors like atmospheric circulation as well as the distribution of the land and the sea.
The main factors which results in the unevenly distribution of the heat and light from the sun to the earth are :
length of the daythe angle of inclination of the rays of the sunearth's rotationconfiguration of the land patternstransparency of the atmosphereThe sun provides more light and heat at the equatorial regions than the polar regions.

Name & describe the six essential activities of the digestive tract.
Answer:
Ingestion: Consuming something orally, whether it be food, drink, medicine, or other substance; the first step of digestion. bolus: a round mass of something, especially of chewed food in the mouth or alimentary canal.
Propulsion: Propulsion means to push forward or drive an object forward. A propulsion system is a machine that produces thrust to push an object forward. On airplanes, thrust is usually generated through some application of Newton's third law of action and reaction.
Mechanical Digestion: Mechanical digestion is a purely physical process that does not change the chemical nature of the food. Instead, it makes the food smaller to increase both surface area and mobility. It includes mastication, or chewing, as well as tongue movements that help break food into smaller bits and mix food with saliva.
Chemical Digestion: Chemical digestion involves the secretions of enzymes throughout your digestive tract. These enzymes break the chemical bonds that hold food particles together. This allows food to be broken down into small, digestible parts.
Absorption: Absorption is a condition in which something takes in another substance. The process of absorption means that a substance captures and transforms energy. The absorbent distributes the material it captures throughout whole and adsorbent only distributes it through the surface.
Defecation: Defecation is the term given for the act of expelling feces from the digestive tract via the anus.

Amoebas make exact copies of themselves. Therefore, they reproduce
A. asexually buy the process of MEIOSIS
B. sexually by the process of MITOSIS
C. sexually by the process of MEIOSIS
D. asexually by the process of MITOSIS
Answer:
D.
Explanation:
You can rule out B and C because offspring produced sexually are not identical to their parents. The amoebas reproduce by binary fission, which is a form of asexual mitosis.
Answer:
D. asexually by the process of MITOSIS
Explanation:
Mitosis is a form of asexual reproduction in simple living organisms. The outcome of each cell cycle is two identical cells. Mitotic checkpoints happen at certain stages of mitosis to ensure that each cell receives the same amount of DNA.

Explain spermatogenesis and oogenesis.
Answer:
yep, my explanation
Explanation:
you see, it is a very dirty cycle, when you have a dioploid cell, you have your typical duplication of sister chromotids, but producing sex cells or gametes which would become a zygote through dirty interactions come to form one dioploid cell and it will start doubling like the rest of the human body, until it comes out of the other human's body. meiosis, or the formation of gamates are created with a crossover where one diolpoid cell takes one half of the chromosome and the other half and exchange a tiny bit of it before splitting into 2 DIFFERENT gametes cells because of the cross-over and hence ther term natural selection
