Answer:
A pseudocoelom is a body cavity that lies between mesodermal and endodermal tissue and is, therefore, not completely surrounded by mesodermal tissue. A “true” coelom is completely surrounded by mesodermal tissue, and can thus be subdivided into compartments.

Explain how the process of PCR can be used in the identification of a disease pathogen. Provide evidence and examples from the outbreak investigation in Unit 1.
Answer:
-in PCR they'll amplify the DNA sequence of the pathogen , then after sequencing , they'll identify the identity of this DNA and identify the pathogen by comparing its genes with the gene bank.
Explanation:
The process of PCR can be used in the identification of a disease pathogen through which the DNA sequence of a pathogen is successfully amplified and then it is matched to the sequence of that which is kept in the gene bank.
What is PCR?PCR stands for Polymerase Chain Reaction. It is a type of reaction in which the amplification of a specific DNA sequence is carried out in vitro. This technique was developed by Kat Mullis in 1985. The whole process is carried out in three stages. They are as follows:
Denaturation.Annealing.Extension.During a PCR test, a small amount of genetic material in a sample is copied multiple times. The copying process is known as amplification. If there are pathogens in the sample, amplification will make them much easier to see.
Therefore, the process of PCR can be widely used in the identification of a disease pathogen.

Select the correct answer.
Read the excerpt from "The Gift of the Magi" by O. Henry. What is the tone of the opening passage?
One dollar and eighty-seven cents. That was all. And sixty cents of it was in pennies, Pennies saved one and two at a time by bulldozing the
grocer and the vegetable man and the butcher until one's cheeks burned with the silent imputation of parsimony that such close dealing
implied. Three times Della counted it. One dollar and eighty-seven cents. And the next day would be Christmas.
There was clearly nothing to do but flop down on the shabby little couch and howl. So Della did it. Which instigates the moral reflection that life
is made up of sobs, sniffles, and smiles, with sniffles predominating.
While the mistress of the home is gradually subsiding from the first stage to the second, take a look at the home. A furnished flat at $8 per week
It did not exactly beggar description, but it certainly had that word on the lookout for the mendicancy squad.
In the vestibule below was a letter-box into which no letter would go, and an electric button from which no mortal finger could coax a ring. Also
appertaining thereunto was a card bearing the name "Mr. James Dillingham Young."
The "Dillingham" had been flung to the breeze during a former period of prosperity when its possessor was being paid $30 per week. Now, when
the income was shrunk to $20, though, they were thinking seriously of contracting to a modest and unassuming D. But whenever Mr. James
Dillingham Young came home and reached his flat above he was called "Jim" and greatly hugged by Mrs. James Dillingham Young, already
introduced to you as Della. Which is all very good.
OA dissatisfied
OB
humorous
OC sarcastic
OD. unhappy
Answer:
A. Dissatisfied
Explanation:
In the beginning of the excerpt, there are many uses of simple and concise sentence structures and a sense of discontent, such as "That was all".
Also, O. Henry includes harsh connotative word choice to effectively describe the apparent disatisfaction of the speaker, exaggerating the situation of how difficult it was to scrape up enough money, using words like "bulldozing" and "silent imputation of parimony". Using such words builds emphasis and importance of what lengths the speaker must endure in order to collect money.
When describing the "furnished flat", it's described as that "it did not exactly beggar description, but it certainly had that word on the lookout for the mendicancy squad". Depicting the flat in such a way evokes a disappointed tone towards how the speaker feels about the flat.

How are scientific theories and scientific laws different? How was the theory of evolution developed? Where can we observe evidence of organisms changing in response to their environment? How do populations of organisms change in response to their environment? What types of adaptations can be observed in nature?
Answer:
Natural selection is one of the central mechanisms of evolutionary change and is the process responsible for the evolution of adaptive features. Without a working knowledge of natural selection, it is impossible to understand how or why living things have come to exhibit their diversity and complexity. An understanding of natural selection also is becoming increasingly relevant in practical contexts, including medicine, agriculture, and resource management. Unfortunately, studies indicate that natural selection is generally very poorly understood, even among many individuals with postsecondary biological education. This paper provides an overview of the basic process of natural selection, discusses the extent and possible causes of misunderstandings of the process, and presents a review of the most common misconceptions that must be corrected before a functional understanding of natural selection and adaptive evolution can be achieved.
