Answer:
III. Equal number of chromosomes.
Explanation:
Comparison between two cells, one cell just before first meiotic division and other cell ready to start mitosis is that both the cells have equal number of chromosomes.
Both the cells have an equal number of chromosomes that is 2n (diploid), where n is 23 and total chromosomes are 46 in each cell but at the meiosis at the end meiosis produces four haploid (n) daughter cells and mitosis produces two diploid (2n) cells.
Hence, the correct answer is "III. Equal number of chromosomes.".

What is the pH of a 0.00125 M HCl solution?
Answer:
[tex]pH=2.9[/tex]
Explanation:
Hello,
In this case, the pH is computed by:
[tex]pH=-log([H^+])[/tex]
Whereas the concentration of hydrogen ions equals the concentration of the acid for strong acids such as hydrochloric acid (HCl) due to its complete ionization in solution, which means that such concentration is 0.00125 M. Thus, the pH turns out:
[tex]pH=-log(0.00125)\\\\pH=2.9[/tex]
Regards.
By definition, the pH of a 0.00125 M HCl solution is 2.90.
You need to know that pH is the Hydrogen Potential. It is a measure of acidity or alkalinity that indicates the amount of hydrogen ions present in a solution or substance.
Mathematically, pH is calculated as the negative base 10 logarithm of the activity of hydrogen ions:
pH= - log [H⁺]
The numerical scale that measures the pH of substances includes the numbers from 0 to 14. The pH value 7 corresponds to neutral substances. Acidic substances are those with a pH lower than 7, while basic substances have a pH higher than 7.
On the other side, a strong acid is an acid that dissociates completely in solution at constant temperature and pressure. Under these conditions, the concentration of a strong acid is equal to the concentration of hydrogen ions (Hydronium or H₃O⁺).
In this case, HCl is a strong acid. Then: [HCl]= [H⁺]= 0.00125 M
Reeplacing in the definition of pH:
pH= - log 0.00125 M
Solving:
pH= 2.90
Finally, the pH of a 0.00125 M HCl solution is 2.90.

We are trying to determine the possible modes of inheritance for some particular human disorder. We have a very small pedigree for this disorder. Assuming the pedigree is accurate, indicate which of the modes of inheritance are consistent with this pedigree:
Answer:
The correct choices will be "X-Linked Recessive".
Explanation:
The heritage couldn't predominate because it would not be prevalent or observable in every decade at least. This could be a recessive gene, then. It would be a recessive condition related to X as it affects only individuals (male).X-Linked succession characteristics measured by chromosome-transported alleles become responded to although the X-linked.What work did Francis Bacon do with the design and organization of libraries ?
The correct answer to this open question is the following.
What Francis Bacon did with the design and organization of libraries was that he created a classification for books and texts, that served as an influence for the way big libraries, such as the Library of Congress classifies books.
Francis Bacon (1561-1626) classified his books into three categories: reason, memory, and imagination. This system was first copied by antifederalist politician Thomas Jefferson to organize his library. In the end, Thomas Jefferson developed a big catalog with 44 categories. That is how Francis Bacon influence the design and organization of libraries.

A sample of a rare metal weighs 18.15 g. Several labs weigh the sample repeatedly. Which lab has the most precise measurements? A. Lab 1: 17.99 g, 18.15 g, 18.23 g B. Lab 2: 18.1 g, 18.3 g, 18.2 g C. Lab 3: 18.11 g, 18.13 g, 18.97 g D. Lab 4: 18.93 g, 19.03 g; 18.95 g
Answer:
D. Lab 4
Explanation:
Measurements in scientific experiments require the collection of data. The precision of a measurement refers to how close a measurement value is to one another.
N.B: The accuracy of a measurement is different from the precision. Accuracy is how close the measured values are to the true value.
To calculate the precision of measured values in different labs for a weighed metal, we use the range of values i.e. the difference between the highest value and lowest value for each lab.
Lab 1: 17.99 g, 18.15 g, 18.23 g
Range= 18.23 - 17.99 = 0.24
Precision result (mean±range)= 18.12±0.24
Lab 2: 18.1 g, 18.2 g, 18.3 g
Range= 18.3 - 18.1 = 0.2
Precision result: 18.2±0.2
Lab 3: 18.11 g, 18.13 g, 18.97 g
Range= 18.97 - 18.11 = 0.86
Precision result: 18.40±0.86
Lab 4: 18.93 g, 18.95 g, 19.03 g
Range= 19.03 - 18.93 = 0.1
Precision result: 18.97±0.1
Based on the range of values in the precision results from each lab, it is evident that Lab 4 has the most precise measurements because the repeated values didn't vary much from one another compared to values from other labs.

What helps the plasma membrane function? channels and chain-like structures O pumps and gelatin-like material O nuclei and endoplasmic reticula O chloroplasts and mitochondria
Answer:
channels and chain-like structures
Explanation:
The plasma membrane contains channels that favor the transport of materials from both sides, i.e., from the intracellular medium to the extracellular environment. Membrane channels are a class of proteins that enable the passive transport of ions and chemical compounds by using the electrochemical gradient in both sides of the membrane. For example, channel proteins in the cell membrane known as aquaporins enable the transport of water across the cell membrane much more rapidly than by diffusion across this barrier.
