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.

Answers

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.

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.

Starting with the European settlers, humans have introduced earthworms from Europe and Asia into North American forests. These introductions continue through the transport of soil that contains non-native earthworms, such as during construction and through the release of non-native earthworms used for fishing. The effects of non-native earthworms are especially large in forests that did not have any native earthworms. For example, forests of the Great Lakes region did not previously have earthworms until humans introduced them. When non-native earthworms are introduced, the thick layer of leaf litter disappears quickly, thereby altering biogeochemical cycles. You conduct an experiment to compare the nitrogen cycle in soils with and without non-native earthworms. Predict the results of your experiment.

Answers

Answer:

The soils with earthworms will show a faster rate of ammonification

Explanation:

Originally, the nitrogen released by organisms when they die (or excrete waste products) is organic nitrogen, e.i., amino acids and nitrogenous bases in DNA. Ammonification is the property that decomposer organisms have to mineralize organic nitrogen in order to produce inorganic nitrogen in the form of ammonium (NH4+). In agroecosystems, earthworm activity can increase the ammonification rate. For example, Lumbricus terrestris is an invasive earthworm (which is native to Europe) that has been shown to increase both ammonification and nitrification (nitrate production) rates in the soil of different ecosystems.

Answers

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.

Describe the characteristics of the keratinocyte membrane that restrict water movement across the membrane. If isolated keratinocytes are placed in a hypotonic solution for 24 hours, explain why there are likely to be far fewer cells at the end of this time than there were at the start.

Answers

Answer:

It has four layers and attach with each other with desmosome.

Explanation:

The keratinocytes are arranged in four different layers which are the stratum basale, stratum spinosum, stratum granulosum, and stratum corneum. These cells are attached with desmosome which is a membrane protein. The presence of these four layers made a barrier against damage done by heat, UV radiation, water loss, pathogens etc. There are fewer cells at the end of the time as compared to the start because may be of the water pressure on the membrane or these cells for a long time.

A test tube is filled with water and a green plant called Elodea. When the plant is exposed to sunlight, it begins to produce bubbles. What is the most likely conclusion for the identity of the gas in the bubbles? Explain.

Answers

Answer:

The correct answer is - oxygen.

Explanation:

The experiment of a test tube and elodea plant in which a plant of elodea is placed in a test tube filled with water and exposed to the sunlight and one is placed in the dark. The plant that is exposed to the sunlight starts forming a gas that can be seen as bubbles in the test tube.

This experiment shows the process of photosynthesis that converts sunlight into glucose with the help of carbon dioxide and water and produces oxygen as a byproduct that releases from the plants.

Thus, the gas that forms in the test tube in the form of bubble is oxygen which is released in the process of photosynthesis.

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

Answers

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.

Answer:

Explanation:

A gamete is a haploid reproductive cell that fuses with another gamete of opposite strain to form a diploid

zygote.

A zygote is a cell formed by the fusion of the male and female gamete before it undergoes division.

gametes are haploid while a zygote is diploid.

There is exchange of genetic material during sexual reproduction and fusion of gametes. Meiosis is also involved.

The opposite occurs in asexual reproduction and mitosis is involved instead.

Asexual reproduction is common in prokaryotes eg bacteria.

At the end of Meiosis II, each daughter cell has 23 single-stranded chromosomes.
True
OR
False

Answers

Answer:

y the end of meiosis, the resulting reproductive cells, or gametes, each have 23 genetically unique chromosomes. ... Each daughter cell is haploid, because it has half the number of chromosomes as the original parent cell.

Explanation:  

30 chromosomes

Each daughter cell will have 30 chromosomes. At the end of meiosis II, each cell (i.e., gamete) would have half the original number of chromosomes, that is, 15 chromosomes. 2.

From a diploid germ cell 2n =24 double stranded chromosomes, meiosis will produce four gamete haploid cells n =12 single stranded chromosomes.

Meiosis produces four with half because double stranded chromosomes represents DNA replication. Twice as much DNA as a diploid cell needs.

From a diploid germ cell 2n =24 double stranded chromosomes, mitosis will produce two diploid daughter cells 2n =24 single stranded chromosomes for the same reason.

DNA replication doubles the genome before cell division. Sister chromatids of double stranded chromosomes represent the replicated DNA. During cell division, sister chromatids of double stranded chromosomes are separated into different cells.

Meiosis has two stages, the first separating homologous pairs of double stranded chromosomes, and then the second stage separating sister chromatids into four haploid (n) gametes.

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

Answers

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.
