BUZZ, BUZZ! Oh, what terrible timing. Tom was in the middle of setting up an experiment in lab when his phone indicated that he

had a voicemail from his 3-year-old's preschool. He finished up his immediate task and checked his messages. The preschool teacher was calling to let him know that his son, Theo, had a fever of 101.7°F and that he didn't seem to be feeling well and needed to be picked up early. Tom sighed and said he would be right there. He went back into lab, diluted back his bacterial culture, put it in the incubator, and decided to do the experiment tomorrow. When he drove to preschool and picked up Theo, he noticed Theo was lethargic and sad. Tom knew that kids get all sorts of random illnesses, so he took Theo home to see if he could figure out if anything else was wrong. Because Theo was 3 years old, he was able to tell his Dad that his throat hurt a lot as he kept rubbing his throat. Theo didn't seem any to be getting any worse, so everyone went to bed. In the middle of the night, Theo wakes up to vomit (repeatedly) and complains of stomach pain.
Tuesday, March 7, 2017

After a night of not very much sleep, Tom checked Theo's temperature again and saw that it was still high. Now he saw that Theo's cheeks were flushed and there was a rash consisting of pink, slightly raised bumps (no pustules) covering his cheeks, chest, and back. Tom placed a call to the pediatrician to set up an appointment for later that morning.

Required:
a. What disease is the boy likely suffering from? Explain your diagnosis.
b. Name and describe the pathogen that causes this disease.
c. Because Theo is going to be taken to the doctor, is it likely to the fatal? What if the year was 1900? Why?
d. Explain what is causing the rash.
e. If the boy was infected with the same pathogen and had the same signs and symptoms, but did not present with a rash, what would the disease diagnosis be?
f. What treatment would the doctor prescribe? Name one example and describe the mechanism of action
g. The boy was given a prescription and started having diarrhea. Is this normal? Why or why not?

Mitosis and meiosis always differ in regard to the presence of a. chromatids. b. homologs. c. bivalents. d. centromeres. e. spin
vlada-n [2515]
c. bivalents. In the initial phase of meiosis, specifically during prophase, bivalents are created, which consist of a tetrad made up of two paired chromosomes and four chromatids—each chromosome originating from one parent. In contrast, mitosis does not involve the formation of bivalents, although chromatids, homologs, centromeres, and spindles are present in both processes.

Respuesta:

A partir del peso molecular dado - 17,000, la proteína de los glóbulos rojos es Hemoglobina A (Hb A).

Explicación:

La técnica utilizada para la separación de moléculas de proteínas según su tamaño molecular en el estudio de biología molecular, junto con un marcador de proteína de referencia para identificar el tamaño exacto de proteína desconocida, se conoce como electroforesis en gel de poliacrilamida con SDS. Durante el proceso de separación de proteínas, ADN y ARN, entre otros, el dodecil sulfato de sodio se utiliza como un compuesto orgánico sintético empleado como tensioactivo en la solución de lisis.

Con base en el peso molecular dado - 17,000, la proteína en los glóbulos rojos es Hemoglobina A (Hb A). Su función consiste en transportar oxígeno desde los órganos respiratorios hacia el resto del cuerpo y tejidos. La Hb A se presenta en forma de tetámero, es decir, contiene cuatro subunidades que consisten en dos subunidades alfa y dos beta, cada una compuesta por 141 y 146 residuos de aminoácidos, respectivamente. Cada subunidad tiene un tamaño molecular de aproximadamente 16,000 daltones y son estructuralmente similares y del mismo tamaño.

Chronic overfishing disrupts a coral reef ecosystem, making the reef more susceptible to bleaching and resulting in die-off even
vlada-n [2515]

Answer:

The word that is missing is Depletion.

 

Explanation:

Depletion of coral reefs can happen as a result of excessive fishing. The demand for fish increases alongside the growing population rate.

One consequence of unsustainable and unmanaged fishing is that certain fish species may be overfished, potentially leading to extinction.

This creates an ecological disruption, which hastens the decline of the Coral Reef.

Cheers!

Show how selection, genetic drift, gene flow, and mutation relate to genetic variation. Match the words in the left column to th
Rainbow [2354]

Answer:

1.  Mutation- enhances genetic variation

2. Selection- may raise, lower, or maintain genetic variation

3. Genetic drift- diminishes genetic variation.

4. Gene flow- could either enhance or reduce genetic variation

Explanation:

1. Mutation denotes changes in an organism's DNA. The mutations lead to new adaptive traits that evolve, which increases the genetic diversity of organisms.

2. Natural selection favors organisms best suited to their environment. Thus, selection can increase, decrease, or keep variation in a population steady.

3. Genetic drift occurs due to random events altering a population's gene pool. When this phenomenon transpires, the genetic variation within that population typically decreases.

4. Gene flow involves changes to the gene pool due to immigration and emigration. This factor can thus increase or decrease genetic variation.
