What is Enzyme ?Proteins called enzymes serve as biological catalysts by quickening chemical reactions. Substrates are the molecules that enzymes can interact with, and the enzyme changes the substrates into other molecules known as products.
According to the type of reaction they catalyze, enzymes are divided into six categories: oxidoreductases, transferases, hydrolases, lyases, ligases, and isomerases. The vast majority of enzymes are proteins structurally. Also RNA molecules have catalytic activity (ribozymes) (ribozymes).
Enzymes are proteins that help speed up metabolism, or the chemical reactions in our bodies. Some compounds are created, while others are broken down. Enzymes are a part of all living things.

The figure below shows the incidence of Bruton's syndrome in the three generations of a family. Bruton syndrome is a rare genetic disorder that is characterized by the mutation in a o gene that prevents the development of certain immune cells. It is an X-linked recessive trait. Determine the genotypes of the individuals in the chart. Let \(X^{B}\) represent the dominant Bruton allele and \(X^{b}\) represent the recessive Bruton allele.
Answers
The genotype of the individuals is found below.

Is there an impact on the environment if blue whales went extinct?
Answers
Answer:
Yes.
Explanation:
Blue whales are the largest animals in the world, and they are the apex predator in the ocean, meaning they help to regulate the population of other species in the ecosystem. As with any species, the loss of blue whales would cause imbalances in the food chain, which would have far-reaching effects throughout the ocean and its inhabitants. In addition, blue whales help maintain the balance of carbon dioxide in the ocean which could be lost if the species were to go extinct.

The component of the cell theory that was contributed by Rudolf Virchow is: b. All cells originate from preexisting cells.
What is Cell Theory?
Cell theory is a fundamental scientific concept that describes the basic unit of life, the cell. It is a set of principles that describe the organization and function of living organisms. The three main components of the cell theory are:
Every living thing is made up of one or more cells.The fundamental unit of structure, organization, and function in all living things is the cell.All cells arise from pre-existing cells.These principles were developed over several centuries by many scientists, including Robert Hooke, Antoine van Leeuwenhoek, Matthias Schleiden, Theodor Schwann, and Rudolf Virchow. The cell theory has been confirmed and expanded upon by modern research and is considered a cornerstone of biology. It provides a framework for understanding the organization and behavior of living organisms and has many practical applications in fields such as medicine and biotechnology.
This is known as the principle of biogenesis, which states that new cells can only arise from preexisting cells. Virchow first proposed this concept in 1855 based on his observations of cellular division in tissues.

During alcoholic fermentation, when is NAD+ converted to NADH -- during the conversion of glucose to pyruvate (glycolysis) or during the conversion of pyruvate to alcohol?
Answers
Answer:
During the conversion of glucose to pyruvate glycolysis or during the conversion of pyruvate to alcohol
Explanation:
During the conversion of glucose to pyruvate, NAD+ is converted into NADH.
What is alcoholic fermentation?Alcoholic fermentation is a biological process that converts sugars into cellular energy while emitting ethanol and carbon dioxide as byproducts.
The NADH + H+ from glycolysis would be recycled back to NAD+ during the fermentation process, allowing glycolysis to continue. NAD+ is reduced during glycolysis to form NADH + H+.
Thus, during this, when glucose is converted to pyruvate, NAD+ is being converted to NADH.

Explanation:
acute lymphocytic leukemia is a form of cancer of the blood and bone marrow( a spongy tissues inside the bone that produced red blood cells) that affect white blood cells.. In Acute lymphocytic leukemia,immature red blood cells are produced rather than matured ones. These occur when bone marrows develop errors in it's DNA and it is the most common type of childhood cancer.
Symptoms include enlarged lymph nodes, bruising, fever, bone pain, bleeding from the gums and frequent infections, pale skin, weakness, shortness of breath.

AP Biology - If 72 out of 200 individuals....(pic is attached) - worth 25 points!
Answers
Answer:
A.) 48%
Explanation:
AA = dominant genotype
Aa = heterozygous genotype
aa = recessive genotype
Hardy-Weinberg Equations:
p² + 2pq + q² = 1 p + q = 1
In this equation, In this equation,
-----> p² = frequency of "AA" -----> p = frequency of "A"
-----> 2pq = frequency of "Aa" -----> q = frequency of "a"
-----> q² = frequency of "aa"
(Step 1)
Determine the frequency of the recessive allele ("a").
72 / 200 = 0.36 recessive phenotype
The only way to have the recessive phenotype is to have the recessive genotype, aa. Therefore, q² = 0.36.
If q² = 0.36, then q = 0.6 (take the square root).
(Step 2)
Determine the frequency of the dominant allele ("A").
p + q = 1
p + 0.6 = 1
p = 0.4
(Step 3)
Determine the frequency of the heterozygous genotype ("Aa").
If -----> p = 0.4 and q = 0.6
Then -------> 2pq = 2(0.4)(0.6) = 0.48
0.48 x 100% = 48% Aa

Flooding and the destruction it may bring are very real risks for people who live in floodplains. Homes might be ruined or damaged populations. Property damage is possible.
If you make preparations now for potential flooding tomorrow, you can prevent it or at least lessen the damage if if live in a floodplain. Flooding can have negative environmental effects such as soil & bank erosion, bed erosion, siltation, or landslides. Flooding can harm plants, and contaminants transported by floodwater can have an impact on the ecosystems, flora, and animals as well as the water quality.
