Respuesta corta: Produciendo un sentimiento de satisfacción.
Explanation
En el texto se hace referencia a una investigación para analizar la relación entre las redes sociales y el cerebro de los adolescentes. Para ello los investigadores utilizaron imágenes magnéticas del cerebros de los 32 adolescentes estudiados. Una vez terminaron el estudio se dan cuenta que "una estructura del cerebro, llamada núcleo accumbens, se activa más cuantos más likes tuviera una imagen". Además, el autor del texto agrega que "Esto es interesante si se tiene en cuenta que este órgano nervioso es el responsable de que experimentemos momentos de placer intensos al ganar un premio, comer helado, etc". De acuerdo a lo anterior se puede interpretar que las redes sociales influyen en el cerebro de los adolescentes debido a que produce en ellos un sentimiento de satisfacción o reconocimiento a recibir "likes" de otras personas. Además, este sentimiento se puede interpretar como aprobación por parte de las demás personas.
A suspension of yeast cells is being grown under anaerobic conditions such that glucose is degraded to ethanol and carbon dioxide. To follow this process by monitoring the release of CO214, at which positions in the glucose molecule would the C14 label need to be incorporated
Answer:
carbons 3 and 4
Explanation:
Alcoholic fermentation is an anaerobic (non-oxygen-requiring) pathway capable of converting one mole of glucose (C6H12O6) into two moles of ethanol (C2H5OH) and two moles of carbon dioxide (CO2), producing during this process two moles of ATP. The overall chemical reaction is as follow: C6H12O6 (glucose) >> 2 C2H5OH (ethanol) + 2 CO2. During this process (fermentation), energy is obtained from the glycolysis process by which each glucose molecule is broken down into two pyruvate molecules (2 CH3COCOO−). Pyruvic acid is an organic acid that ionizes to produce a hydrogen ion and a molecule of pyruvate. Subsequently, this pyruvate is then converted into ethanol and CO2, generating NAD+, i.e., the oxidized form of nicotinamide adenine dinucleotide or NAD, which is required for glycolysis (and therefore to produce ATP). Moreover, dismutation refers to the redox reaction by which one compound with an intermediate oxidation state converts into two compounds. In consequence, the CO2 generated during fermentation arises from the dismutation of pyruvic acid. During this process, the major source of CO2 is carbon 3 (C3) and carbon 4 (C4) of the glucose as a result of the dismutation of pyruvate, and thereby these positions in the glucose molecule would the C14 label need to be incorporated.
In working with Drosphilia it is common to use a balancer stock to maintain mutations of interest. The balancer chromosomes are generally carrying multiple inversions on them. What effect would the inversions have on meiosis
Answer:
Fusion or pairing does not occur.
Explanation:
Inversions mutation leads to lowered fertility due to production of unbalanced gametes in the meiosis cell division. Chromosome inversions have no effect on mitosis, but they has affect meiosis because inversions changes the gametes which is only present in meiosis. If an inversion present is in the heterozygous condition, pairing of chromosomes cannot occur in a simple linear fashion due to change of sizes. But if the inverted chromosome segment has the proper size so it can paired with each other.

__________________ moves the respiratory medium over the respiratory surface.
Group of answer choices
perfusion
percolation
ventilation
diffusion
Answer:
ventilation
Explanation:
Breathing, also known as ventilation, is the process of moving air or water in order to facilitate the gas exchange between the external and internal (body) environment, mostly to eliminate carbon dioxide (CO2) and bring in oxygen (O2). For example, fish are aquatic animals that need to run water over their gills to get the O2 that they need to survive (gills are organs that create a large surface area for ventilation). Moreover, insects ventilate their tracheal system to get O2. Finally, terrestrial vertebrates (i.e., amphibians, reptiles, birds, and mammals) use organs called lungs to exchange O2 and CO2 between their cells and the external environment.
What is the role of DNA polymerase enzymes in replication?
(A) unzipping the double helix by breaking down the hydrogen bonds
(B) adding the free nucleotides to the complementary strand of DNA
(C) splitting the DNA molecule
(D)connecting the fragments on the lagging strand of DNA
Answer:
A
Explanation:
the function of DNA polymerase is to unzip the double helix structure of DNA by breaking down the weak hydrogen bond
Answer:
(B) adding the free nucleotides to the complementary strand of DNA
Explanation:
A DNA polymerase is an enzyme capable of creating new DNA molecules by sequentially adding nucleotides to the three prime (3')-end of a DNA strand. A DNA strand is a polynucleotide chain composed of a linear series of nucleotides, each consisting of a deoxyribose sugar, and phosphate, and a base (i.e., thymine, guanine, cytosine and adenine). Before a cell starts to divide, it needs first to replicate its genetic material by using DNA polymerases that duplicate the cell's DNA during the interphase (S phase). During this process (DNA replication), an enzyme known as helicase unwinds the DNA molecule, which is made up of two antiparallel strands oriented in opposite 3′-5′ directions to each other. Subsequently, each strand is used as a template for its replication through DNA polymerases that can add nucleotides (one at time) to an existing short fragment of RNA, i.e., the primer sequence, which is paired with the template DNA strand.

g An Hfr strain is produced when Select one: A. an F episome is transferred to a new cell. B. an F episome leaves the E. coli chromosome. C. an F episome leaves the host chromosome and removes some of the host chromosome. D. an F episome integrates into the E. coli chromosom
Answer:
A. an F episome is transferred to a new cell.
Explanation:
Hfr strains arise from the integration of the plasmid into the bacterial cell in one of several ways such as the recombination of events. Most commonly are formed by the UV-induced integration of E coil F factor. It tries to transfer a copy of the F factors as well the entire chromosome to the recipient bacterium.how does Fibrocartilage receive it's nutrients?

Describe how oxygen is transported in blood, and explain how temperature, pH, BPG, and affect oxygen loading and unloading.
Solution :
The flow of oxygen in the blood is been transported by two ways :
1. in plasma 1.5%
2. bound to hemoglobin 98.5%
As the oxygen loads in the body, affinity of the Hb makes the oxygen loading very efficient in the blood. The Hb molecule gets saturated when all the 4 hemes are oxygen binded.
The decreased pH weakens the hemoglobin oxygen binding in the tissues.
Higher temperatures in the oxygen means a lower affinity and thus more oxygen is released and so the oxygen unloads.
Increase in the temperature, the BPG and the modification of the structure in the hemoglobin decreases the affinity for the oxygen and further enhances the unloading of the oxygen in the blood.
Identify two means by which meiosis results in genetically unique gametes, and explain why this is important.
Explanation:
Meiosis is beneficial as it produces gametes that are genetically different to the parent cell, and when the gametes combine the offspring produced is made from combination of genes from both mother and father. The offspring is genetically unique, there is no other organism on the Earth with the exact same DNA sequences on their chromosomes.
