Answer:
[tex]\boxed {\boxed {\sf 10^5 \ or \ 100,000 \ times \ more \ acidic}}[/tex]
Explanation:
The pH scale stands for the power or potential of hydrogen. It measures how acidic or basic a solution based on the concentration of hydrogen ions and a scale from 1 to 14.
This scale is unique because it is logarithmic. So, every time the pH changes by 1 on the scale, the actual concentration of the solution increases or decreases by a tenfold.
So, a solution with a pH of 7 is ten times more acidic than a solution with a pH of 8. This can be translated to:
[tex]10^ {difference \ in \ pH}[/tex]
The black coffee has a pH of 5 and the hand soap has a pH of 10. We want to find how many times more acidic coffee is, so we subtract 5 from 10 and get 5. The difference in pH is 5.
[tex]10^5=100,000[/tex]
Coffee is 10⁵ or 100,000 times more acidic than hand soap.
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.

Answer:
Man (dimples and freckles) - FfDd
Woman (no dimples and no freckles) - ffdd
Child (no dimples and no freckles) - ffdd
Explanation:
According to this question, the possession of freckles (F) and dimples (D) are the dominant traits. The union of a man with dimples and freckles and a woman with no dimples and freckles (ffdd) gave rise to a child that has no dimples or freckles (ffdd).
Since the child has a recessive 'ffdd' genotype, it means that the father will likely have a heterozygous genotype (FfDd). Therefore, the genotypes of the three persons involved are;
- Man (dimples and freckles) - FfDd
- Woman (no dimples and no freckles) - ffdd
- Child (no dimples and no freckles) - ffdd

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
__describes non-seasonal changed in the structure or composition of an ecological community over time
Ecological succession
Community ecology
Ecosystem dynamics
Answer:
Ecological succession
Explanation:
In ecology, ecological succession is described as a series of change in the structure or composition of an ecological community over a period of time. There are two types of ecological succession namely: primary succession and secondary succession.
Primary succession occurs on a barren land with no prior growth while secondary succession occurs in an area that has been colonized before but disturbed by an environmental hazard.
Describe how human activities cause desertification including desertification’s impacts on soil and the role of modern agriculture in causing Desertification.
Answer:
Desertification is the destruction of the biological potential of the land and it is generally viewed as an advanced stage of land degradation. human activities also cause the process such as poor irrigation practices, deforestation, the expansion and intensive use of agricultural lands, and overgrazing.
Such human activities put enormous pressure on the land by altering its soil chemistry and hydrology. Modern agriculture causing a negative impact on the soil and land by overexploiting the biological and chemical potential of the land.

which language is this?
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.

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.
