Predation and parasitism are similar because in both predation and parasitism -
both organisms are harmed in some way.
one organism is harmed while the other benefits.
one organism is neither harmed nor benefits.
both organisms receive a benefit.
Answer: on organism is harmed while to the other benefits
Explanation:
Predation and parasitism are similar because, in both predation and parasitism, one organism is harmed while the other benefits. Therefore, option B is correct.
What are predation and parasitism?The act of eating all or a portion of the body of another organism, the prey, is known as predation. Herbivory is the term for predatory behavior in which the prey is a plant.
When one creature, the parasite, feeds on another, the host, hurting or even killing the host, the connection is said to be parasitism. The parasite stays within or on the host's body. Tapeworms, fleas, and barnacles are a few examples of parasites.
Thus, predation and parasitism are similar because, in both predation and parasitism, one organism is harmed while the other benefits. Therefore, option B is correct.

Makali and his parents recently emigrated from the highlands of Papua New Guinea. His family is part of the famous Fore tribe; after living in the tribe for most of their lives, they decided to give Makali a different life in the United States. His mother starts to cry as she recalls that both her parents died in the kuru epidemic that made the tribe famous, and she is terrified that Makali might be coming down with kuru. His father interjects to say that it is not possible and that he is far more concerned that Makali has some other infectious disease to which he had never previously been exposed.
His father says that Makali had a severe allergic reaction to the tetanus/pertussis booster shot as a child and has been unable to be re-vaccinated due to the risk of anaphylactic shock. Therefore, Makali may be susceptible to whooping cough (pertussis). This would not have been a concern 10 years ago, but vaccination rates for whooping cough have plummeted in the United States, eliminating herd immunity and sparking a return of the disease in some regions. Ironically, vaccination rates in the Fore tribe are much higher than in the United States, so Makali's parents had concerns about coming to the United States, which is falling behind other countries in this area of basic medical care!
One of the doctors you are working with says that checking immunoglobulin (Ig) levels should reveal if there is a serious infection. He also points out that kuru does not cause immunoglobin levels to rise. If Makali does have kuru, a brain biopsy may be required to make a definitive diagnosis.
1. Select the next step or steps that would be appropriate to diagnose Makali?
a. Test immunoglobulin (IgG, IgA, and IgM) levels in the blood for signs of infection.
b. Perform a brain biopsy.
c. Interview one of Makali's friends to ask about the day he first became sick.
2. Which statement most accurately describes the citric acid cycle?
a. It is an unregulated process, like an intersection without signal lights.
b. It is the main center of ATP production during anaerobic metabolism.
c. It plays a central role in key metabolic processes in the cell, with many metabolic intermediates leaving and entering.
d. It serves a catabolic role only, which is to generate ATP and reducing equivalents for cellular energy needs.
Answer:
Explanation:
It is important we understand what is immunoglobulin test.
Immunoglobulins, also known as antibodies, are measured by the test carried out in the blood. Antibodies are proteins produced by the immune system to combat pathogens such as viruses and bacteria that cause disease. Immunoglobulins are proteins produced by the body to combat various substances.
The immunoglobulin assay tests three forms of immunoglobulins in total. IgG, IgM, and IgA are the three types of antibodies. IgG, IgM, and IgA levels that are too low or too high may indicate a severe health condition.
Thus, from the above question; the next step that would be appropriate is:
Assuming the test uncovers an increase in immunoglobulin, it demonstrates contamination or infection. Thus, a fitting treatment ought to be begun against the infection.
However, suppose the text doesn't uncover an increase in immunoglobulin and assuming he shows manifestations of symptoms, then the brain biopsy ought to be performed to affirm the diagnosis of kuru.

The citric acid cycle is the metabolic center of the cell. It is the doorway to the aerobic metabolism of any molecule that can be changed into an acetyl group or a part of the citric acid cycle. The cycle is additionally a significant wellspring of prototype for building blocks of numerous different molecules like amino acid and nucleotide base.
Thus, the best accurate statement is: Option C

Prophase
Explanation:
During prophase, the nuclear envelope and nucleolus are dissolved and the chromosomes condense. The centrioles and spindle fibers begin to form at opposite poles of the cell.
Answer:
telophase
Explanation:
Spindle fibers disperse as the chromosomes are separated and become housed within two new nuclei.
When the gene encoding a certain cytoskeleton protein is deleted, the resulting mutant cells round up and do not form their normal appendages. These mutants can be rescued when a gene encoding an N-terminal green fluorescent protein (GFP) fusion of the protein is expressed, but not when a gene encoding a C-terminal GFP fusion is expressed. Which fusion protein is appropriate to use in studying cellular localization and activity
Answer: N-terminal green fluorescent protein (GFP)
Explanation:
Protein synthesis takes place in ribosomes located in the cell cytoplasm, in which amino acids are transported by transfer RNA corresponding to each amino acid to the messenger RNA where they bind in the appropriate position to form new proteins. The messenger RNA has a sequence of nucleotides that are translated into protein, as each codon (set of three amino acids) codes for one amino acid.
Genes are the storage units of genetic information, so they are segments of DNA that contain the information on how the cells of the organism should function. Each gene codes for a protein, so if a gene is damaged or absent, the protein will not be obtained. In this case, mutant cells with a deleted gene, will round up and wont form their normal appendages. This mutation can be rescued or repaired with a gene that encodes an N-terminal green fluorescent protein (GFP) fusion of the protein. The N-terminal end is the amino-terminal end and it refers to the end of a protein that ends with an amino acid that has a free amino group. The C-terminus or carboxyl-terminus is the end of a protein that ends in a carboxyl group. The convention for writing peptides is to place the C-terminal end to the right and write the sequence from the N- to the C-terminal end. So, when an N-terminal green fluorescent protein (GFP) fusion of the protein is expressed, the gene will produce the protein with a GFP tag.
GFP is Green Fluorescent Protein, and it is a protein produced by the jellyfish Aequorea victoria that emits bioluminescence in the green region of the visible spectrum. When a gene is fused to another gene (at either the N- or C-terminus, although in this case it is the N-terminus), the entire messenger RNA is translated together as if it were a single fused protein. Thereby, since the protein will be produce with a GFP tag, it can be seen under the microscope and it will be apropiate to use in studying cellular localization and activity.
There are some considerations that this problem does not question, such as that there must be a start codon for protein synthesis and a stop codon, and this stop codon must not be in the middle of the gene or between the gene and the GFP tag.

Describe DNA synthesis in detail
Answer:
DNA synthesis is the biological process by which a deoxyribonucleic acid (DNA) molecule is created. In the cell, each of the two strands of the DNA molecule acts as a template for the synthesis of a complementary strand.
Answer:
The discovery of the double-helical nature of DNA by Watson & Crick explained how genetic information could be duplicated and passed on to succeeding generations. The strands of the double helix can separate and serve as templates for the synthesis of daughter strands. In conservative replication the two daughter strands would go to one daughter cell and the two parental strands would go to the other daughter cell. In semiconservative replication one parental and one daughter strand would go to each of the daughter cells.
Through experimentation it was determined that DNA replicates via a semiconservative mechanism. There are three possible mechanisms that can explain DNA's semiconservative replication.
(a) DNA synthesis starts at a specific place on a chromosome called an origin. In the first mechanism one daughter strand is initiated at an origin on one parental strand and the second is initiated at another origin on the opposite parental strand. Thus only one strand grows from each origin. Some viruses use this type of mechanism.
(b) In the second mechanism replication of both strands is initiated at one origin. The site at which the two strands are replicated is called the replication fork. Since the fork moves in one direction from the origin this type of replication is called unidirectional. Some types of bacteria use this type of mechanism.
(c) In the third mechanism two replication forks are initiated at the origin and as synthesis proceeds the two forks migrate away from one another. This type of replication is called bi-directional. Most organisms, including mammals, use bi-directional replication.

Answer: c. Liquids leak into the ground
Explanation:
Andrew did a mutant screen with his favorite bacterium that he used for marine phage hunting. He identified three base-substitution mutations on the bacterial recA gene:
Mutant A: A base substitution occurred, which changed T to C, and consequentially abolished transcription of the recA gene.
Mutant B: A base substitution, which changed codon 2 from ACC to ACT, which did not change encoded amino acid.
Mutant C: A base substitution occurred, which changed codon 3 from TCA to a stop codon TGA.
Based on the above info, which of the mutants would still have functional RecA protein?
a. Mutant B
b. Mutant A
c. Mutant C
Answer:
a. Mutant B
Explanation:
This question is describing a kind of mutation called SUBSTITUTION MUTATION, in which one or more nucleotide base is replaced by another in a sequence. In this case, the base-substitution mutations occcurs in the bacterial recA gene sequence.
However, base substitutions can be grouped into three based on the different results it yields namely: missense mutation, nonsense mutation, silent mutation.
- In Mutant A: A base substitution occurred, which changed T to C, and consequentially abolished transcription of the recA gene. This is an example of missense mutation because it changes the sequence.
- In Mutant B: A base substitution, which changed codon 2 from ACC to ACT, which did not change encoded amino acid. This is an example of silent mutation because it does not alter the sequence of the gene.
- In Mutant C: A base substitution occurred, which changed codon 3 from TCA to a stop codon TGA. This is an example of nonsense mutation because it leads to a STOP CODON.
According to the question, MUTANT B would still have functional RecA protein because it doesn't change the encoded amino acid sequence, which will still lead to the production of the RecA protein.

Fruiting Bodies of Fungi The recognizable forms of fungal reproductive bodies, or fruiting bodies, encountered in nature vary structurally. Common forms of fungal fruiting bodies include trumpet, club fungus, bracket, cup fungus, gill fungus, bolete, puff ball, and stinkhorn. Close observation of fruiting body anatomy can lend clues during identification of a species. Differing species of fungi can appear similar, and it is never advised to eat a wild mushroom because poisonous varieties can resemble edible ones.
1. Fungal fruiting bodies, or reproductive bodies, have different structural forms.
a. true
b. false
2. Many experiments require student-supplied items, such as _____.
Answer to Question 1:
True
Explanation
As indicated in the passage, fruiting bodies of fungi differ structurally. However, different species can appear to be similar and often misleading thus creating the risk of food poisoning.
Question 2:
Many experiments require student-supplied items, such as _____.
1. Chicken
2. Fresh flowers
3. Distilled water
4. All of the Above.
Answer to Question 2:
The correct answer is 3.
Explanation
Water comes in varying degrees of purity. When water that contains other substrates or impurities is used for an experiment, it distorts the results and creates errors. So the scientist's ability to determine the root of a problem becomes enervated.
Using distilled water impurities removes the possibility of such an error. Distilled water is also used for cleaning laboratory equipment.
