Largest mountains such as the Himalayas occur where two continental plates converge
The formation of mountains occurs due to the movement of plates, which are sections of Earth's crust. Moreover, this phenomenon happens when two plates converge or collide as this causes one plate to move beneath the other and creates elevations such as mountains.
Besides this, the formation of big mountains such as the Himalayas is mainly the result of continental plates converging (plates that form continents), for example, the Himalayas formed as the Eurasian and Indian plates collided.

Group of answer choices
A) 3x
B) 30x
C) 100x
D) 1,000x
Answer:
The correct answer is - D) 1000x.
Explanation:
pH is a logarithmic scale, 1 reading change leads to the results in ten-fold in the H+ concentration in acidity/basicity. The more H + ions found in solution, the more acidic the substance is as acids donate H + ions.
You can calculate the concentration of H + from the pH and the equation
p H = − log [ H + ]
arrange again
[ H + ] = 10 − p H
So for a pH of 8, we get [ H + ] = 10 ^− 8
For a pH of 5, we get [ H + ] = 10^ − 5
10 ^−5 /10 ^− 8= 10 ^3
= 1000

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.

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.

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.
identifying earths four spheres
match each of earths spheres
Answer:
cryosphere → glaciers, ice caps, ice bergs
atmosphere → air surrounding earth
biosphere → all of Earth's living things
geosphere → Earth's interior, rocks, minerals, and landforms
hydrosphere → oceans, lakes, rivers, streams, and groundwater
Explanation:
The above are properly matched.
Cryosphere is known as part of the earth were water is in solid form. This has to do with glaciers, ice, ice bergs, etc.
Atmosphere has to do with the part of the earth that is gaseous. This has to do with the air found on earth.
Biosphere is the living part of the earth. All things are found in the biosphere.
Geosphere is known to be earth itself which is made up of the landforms, rocks, minerals, earth's interior, etc.
Hydrosphere has to do with the liquid part of the earth. It has to do with the water bodies.

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.The video compares the key similarities and differences between mitosis and meiosis.

A single division occurs, separating sister chromatids Homologous chromosomes pair up and form chiasmata d. Daughter cells contain recombinant chromosomes e. Process starts with a diploid cell Homologous pairs of chromosomes line up on the metaphase plate f. End result is four haploid cells that are genetically different from each other and the parent cell g. Duplicated chromosomes line up Individually on the metaphase plate in a diploid cel h. End result is two diploid cells that are genetically identical to each other and the parent cell Mitosis Melosis Both mitosis and meiosis
Answer:
Mitosis:
A single division occurs, separating sister chromatids
End result is two diploid cells that are genetically identical to each other and the parent cell
Meiosis:
The first division separates homologous pairs; the second division separates sister chromatids
Homologous chromosomes pair up and form chiasmata
Homologous pairs of chromosomes line up on the metaphase plate
Daughter cells contain recombinant chromosomes
End result is four haploid cells that are genetically different from each other and the parent cell
Mitosis and Meiosis:
Chromosomes duplicate during interphase
Process starts with a diploid cell
Duplicated chromosomes line up Individually on the metaphase plate in a diploid cell
Explanation:
Mitosis is the division of vegetative cells while meiosis involves the division of sex cells. Both divisions start with diploid parental cells but while the daughter cells in mitosis are also diploid, those of meiosis are haploid. This is why mitosis is referred to as equational division while meiosis is known as reductional division.
A cell that will undergo mitosis or meiosis would first have its genetic materials duplicated during interphase in addition to the synthesis of other important biochemicals such as proteins. Mitosis involves just a single division of the sister chromatids with two genetically identical daughter cells who are also clones of the parent cells resulting.
Meiosis, on the other hand, involves two divisions - the first one happens to separate homologous chromosome pairs while the second division separates sister chromatids just like in mitosis. During the early stage of meiosis, homologous chromosomes synapsed through the formation of a synaptonemal complex to form tetrads. Thereafter, synapsed chromosomes exchange chromosomal segments at a point known as chiasmata. All these happen at the prophase stage of meiosis I. The paired homologous chromosomes are then lined up at metaphase where they are engaged by the spindle fibers.
Meiosis II and mitosis are more or less the same with the chromosomes condensing at the prophase and the formation of metaphase plates at the metaphase. Sister chromatids are pulled apart and they migrate to the opposite poles at the anaphase and telophase.
