Stem cells are used to treat some human diseases.
Stem cells can be collected from early embryos. These stem cells have not begun to
differentiate, so they could be used to produce any kind of cell, tissue or organ. The
use of embryonic stem cells to treat human diseases is new and for some diseases,
trials on patients are happening now.
Stem cells can also be collected from adult bone marrow. The operation is simple
but may be painful. Stem cells in bone marrow mainly differentiate to form blood
cells. These stem cells have been used successfully for many years to treat some
kinds of blood disease. Recently there have been trials of other types of stem cell
from bone marrow. These stem cells are used to treat diseases such as heart
disease

It is very difficult to add or remove electrons from an atom that has eight electrons in its outer shell.
True
False
Explanation:
Electrons are typically removed from the valence shells, which are the highest s and p orbitals. Also, Hund's rule still applies here, but backwards. Electrons will be removed from their orbitals until all of them are unpaired, and then the unpaired ones will be removed.
May be true because velence shell is the outermost shell which can be removed.
How Enzymes Function Enzymes are biological catalysts. They can increase the rate of chemical reactions as much as a millionfold by lowering the energy barrier of a reaction.
Part A - Enzymes and activation energy The graph presents three activation energy profiles for a chemical reaction (the hydrolysis of sucrose): an uncatalyzed reaction, and the same reaction catalyzed by two different enzymes. Rank these by reaction rate, as measured by the rate of product formation (from the most product formed to the least product formed). To rank items as equivalent, overlap them.
Part B - Factors that affect enzymes Complete this vocabulary exercise relating to enzymes. Match the words in the left-hand column to the appropriate blank in the sentences in the right-hand column. HelpReset cofactor specific denatured substrate active site catalyst complex
1. An enzyme is when it loses its native conformation and its biological activity.
2. An enzyme is considered a because it speeds up chemical reactions without being used up.
3. An enzyme is considered because of its ability to recognize the shape of a particular molecule.
4. A , such as a vitamin, binds to an enzyme and plays a role in catalysis.
5. When properly aligned, the enzyme and substrate form an enzyme-substrate (ES) .
6. A substrate binds to an enzyme at the , where the reaction occurs.
7. In a catalyzed reaction a reactant is often called a _________.
Answer:1. An enzyme is denatured when it looses its native conformation and its biological activity. Enzyme is a protein and at high temperatures, the shape of the proteins is altered, preventing it from its function. In addition change in pH above optimal may also cause denaturation of enzymes inactive.
2. An enzyme is considered a catalyst because it speeds up chemical reaction without being used up. A catalyst is a substance that speeds up chemical reactions by reducing the activation energy of the reactants, they are not consumed during the reactions. Enzyme are biochemical catalysts that speeds up chemical enzymatic reactions without being consumed just like normal catalysts.
3. An enzyme is considered specific because of its ability to recognize the shape of a particular molecule. One property of enzyme is that they are substrate specific and will act on specific substrate, others will act on a specific type of chemical bond or functional group, while others will catalyze only one reaction (absolute specificity)
4. A cofactor such as a vitamin, binds to an enzyme and plays a role in catalysis. Cofactors are mostly metal ions (such as Zn ions or iron ions) or coenzymes are inorganic and organic chemical that aid the activity of enzymes. Coenzymes are non protein molecules mostly vitamins or vitamins derivatives that enhance enzyme activity.
5. When properly aligned, the enzyme and substrate form an enzyme-substrate (ES) complex. Es complex is the intermediate formed when a substrate molecule interacts with the active sites of an enzyme. After the formation of the complex then the substrate undergoes a chemical reaction and is converted to product.
6. A substrate binds to an enzyme at the active-site, where the reactions occurs. Active sites is a region on the enzyme where substrate molecules bind and undergoes a chemical reaction where it is converted to product. These sites contain the binding site and the catalytic site.
7. In catalyzed reaction, a reactant is often called a substrate. Substrate molecule is the substance that is acted upon by an enzyme and is converted to a product. The substrate forms an interaction with the binding site of the active site then the catalytic site of the active site converts the substrate to a product during catalysis.
1. Denatured
2. Catalyst
3. Specific
4. Cofactor
5. Complex
6. Active Site
7. Substrate
The induced fit model states an substrate binds to an active site and both change shape slightly, creating an ideal fit for catalysis. When an enzyme binds its substrate it forms an enzyme-substrate complex. ... The enzyme will always return to its original state at the completion of the reaction.
"The active site of the enzyme has a complementary rigid structure" belongs to the key and lock system

Substances that do not form ions when they dissolve in water are called non-electrolytes. And example of a non-electrolyte is sugar. Sugar will readily dissolve in water but doesn't form cations and anions in solution. That is, there are no charge carriers formed.
Which of the following allows water to move much faster across cell membranes? A) the sodium-potassium pump B) ATP C) peripheral proteins D) aquaporins
Answer:
D
Explanation:
I believe the answer would be aquaporins
Aquaporins efficiently speed up the total rate of water diffusion across the cell membrane due to the slow diffusion of water through the lipid bilayer, hence option D is correct.
What are aquaporins?Aquaporins (AQP) are essential membrane proteins that act as conduits for the passage of water and, occasionally, tiny solutes.
The Na+ K+ pump is an electrogenic transmembrane ATPase that was initially identified in 1957. It is located on the cytosolic side of the cell's outer plasma membrane. For every ATP, the Na+ K+ ATPase pumps 3 Na+ out of the cell and 2K+ into the cell.
Therefore, animals, plants, and microorganisms all have them preserved. Every aquaporin molecule has a pore in the middle, according to structural investigations of the molecules.

With support for cases such as Brown v. Board of Education, the National Association for the Advancement of Colored People (NA
its attention during the early days of the civil rights movement on doing which of the following?
Answer:
Although the Declaration of Independence stated that "All men are created equal," due to the institution of slavery, this statement was not to be grounded in law in the United States until after the Civil War (and, arguably, not completely fulfilled for many years thereafter). In 1865, the Thirteenth Amendment was ratified and finally put an end to slavery. Moreover, the Fourteenth Amendment (1868) strengthened the legal rights of newly freed slaves by stating, among other things, that no state shall deprive anyone of either "due process of law" or of the "equal protection of the law." Finally, the Fifteenth Amendment (1870) further strengthened the legal rights of newly freed slaves by prohibiting states from denying anyone the right to vote due to race.
Despite these Amendments, African Americans were often treated differently than whites in many parts of the country, especially in the South. In fact, many state legislatures enacted laws that led to the legally mandated segregation of the races. In other words, the laws of many states decreed that blacks and whites could not use the same public facilities, ride the same buses, attend the same schools, etc. These laws came to be known as Jim Crow laws. Although many people felt that these laws were unjust, it was not until the 1890s that they were directly challenged in court. In 1892, an African-American man named Homer Plessy refused to give up his seat to a white man on a train in New Orleans, as he was required to do by Louisiana state law. For this action he was arrested. Plessy, contending that the Louisiana law separating blacks from whites on trains violated the "equal protection clause" of the Fourteenth Amendment to the U.S. Constitution, decided to fight his arrest in court. By 1896, his case had made it all the way to the United States Supreme Court. By a vote of 8-1, the Supreme Court ruled against Plessy. In the case of Plessy v. Ferguson, Justice Henry Billings Brown, writing the majority opinion, stated that:
