Answer:
Decreases the necessary activation energy to speed up the chemical reaction.
Explanation:
This picture shows substrates binding to the activation site of an enzyme causing the enzyme to change shape and therfore speeds up the chemical reaction.
What are the building blocks of proteins? If all proteins are made of the same
building blocks, how can there be so many different types of proteins with different
functions?
Answer:
The basic building blocks of proteins are called amino acids. In proteins, amino acids are arranged into a linear molecule called a polypeptide chain. Some proteins only consist of a single polypeptide chain while more complex proteins are made out of multiple polypeptide chains bonded together.
Explanation:Proteins are formed out of long linear molecules of amino acids called polypeptide chains. The identity and function of a protein are determined by its sequence of amino acids and the 3-D structure of its polypeptide chains. Amino acids are stored in DNA in the form of sequences of nucleotide bases.

Some viruses attack cells by inserting their own DNA into the host cells’ DNA. Why might it be simpler for these viruses to attack prokaryotic cells than eukaryotic cells?
A. Prokaryotic cells have less DNA than do eukaryotic cells.
B. The rapid growth of prokaryotic cells generates more viruses.
C. Unlike eukaryotic cells, prokaryotic cells do not have a nucleus.
D. The cell wall in prokaryotic cells is a less effective barrier.
Answer:
C
Explanation:
Because eukaryotes have membrane bound nucleus where they store their generic information

A person with a low number of white blood cells could have difficulty in fighting infections and A decrease in the number of lymphoid stem cells could result in a decrease in red blood cell.
What is nucleotide?It is the sub units and buIlding blocks of DNA. It is made up of a five-sided sugar, phosphate group and then a nitrogen base.
These groups make the backbone of the DNA helix. If you look at a DNA helix, they make the side of the ladder or the side portion. They connect to a nitrogen base which make the steps of the ladder. The type of sugar that is used in a DNA helix is called deoxyribose.
Nitrogen bases are the molecules that make up the steps of the ladders. There are four different nitrogen bases, namely; Guanine, Thymine,Adenine and Cytosine.
Pyrimidines are compounds that make a single 6-sided ring. Examples of pyrimidines are Cytosine and Thymine. Purines on the other hand make 5-sided and 6-sided rings.
Therefore, A person with a low number of white blood cells could have difficulty in fighting infections and A decrease in the number of lymphoid stem cells could result in a decrease in red blood cell.

3) Describe a eukaryotic cell. Your description should include where you would expect to
find these types of cells.
4)Describe a prokaryotic cell. Your description should include where you would expect to
find these types of cells.
3)Eukaryotic cells have membrane-bound organelles. They have a nucleus. They are usually found in animals and plants. In all multicellular organisms and some unicellular(amoeba)
4)Prokaryotic cells don't have a nucleus. They don't contain membrane-bound organelles they only contain ribosomes.They are much smaller. Bacteria are prokaryotes.
Cellular respiration is a process in which animal cells use ____ taken in from the atmosphere.
1) carbon dioxide
2) hydrogen
3) oxygen
Answer:
How does cellular respiration work in animals?
When an animal breathes, it takes in oxygen gas and releases carbon dioxide gas into the atmosphere. This carbon dioxide is a waste product produced by the animal's cells during cellular respiration. Cellular respiration occurs in the individual cells. Digested foods have chemical energy stored in them.
Explanation:
DNA evidence analysis is an imperfect science. Provide two reasons why this may be the case.
For my Biomedical Science Class
Answer:
Not all DNA that was found at the scene has to be related to the scene.
Explanation:
Just because DNA was found at the scene, that doesn't mean that the person there is actually guilty. For example, in a case where person B is guilty, a strand of hair from Person A could be carried over to another scene on Persons B's clothing.
Answer:
Because DNA is more reliable than other forensics, scientists have shrugged off suggestions that it could fall victim to the vagaries of bias. But Dror noted that much DNA analysis involves interpretation. With interpretation comes subjectivity, and with subjectivity can come error. Only one-tenth of 1 percent of human DNA differs from one individual to the next and, although estimates vary, studies suggest that forensic DNA analysis is roughly 95 percent accurate.

explain how darwin's journey to the galapagos islands contributed to his creation of the theory of evolutions.
Explanation:
During his visit to the islands, Darwin noted that the unique creatures were similar from island to island, but perfectly adapted to their environments which led him to ponder the origin of the islands' inhabitants.
Among those that struck Darwin so greatly were the finches that are now named in his honor. Darwin would later base some of his thought from the supposing that these finches were all descendents of the same lineage.
