A. 8; 32

B. 10; 29

C. 12; 20

D. 5; 45

Carl is counting the number of bones in a human skeleton. He counted 198 bones. There are actually 206 bones in the human body.
vazorg [7]

Answer: The percent error is 3.88%

Explanation:

Percent error = [(Actual bones - Counted bones)/ Actual bones] X 100%

= [(206 - 198)/206] X 100%

= [8/206] X 100%

= 3.88%

Thus, Carl's percent error is 3.88%

What happens to a potassium atoms electrons when it becomes an ion?
Scrat [10]
The alkali metals in group l of the periodic table all have a single electron in the outermost shell. These metals form covalent bonds with for example the halogens, which have 7 electrons in their outer shell.
When the alkali metal halide, such as KCl is dissolved in water, it dissociates into ions. The K atom loses the single electron, and therefore has a positive charge. In turn, the chloride atom gains the electron and becomes the negatively charged chloride ion.

In humans the genetic commonality of height and skin tone is that they are both
lubasha [3.4K]

Answer:

In humans the genetic commonality of height and skin tone is that they are both <u>Polygenic Traits.</u>

Explanation:

Polygenic traits can be described as those characteristics for which there is more than one gene to determine its inheritance. The outcomes of polygenic genes result in many differentiated phenotypes. For example, the difference in height, the difference in skin colour etc.

Polygenic traits occur because one allele for a gene does not have complete dominance over the other gene. This is termed as incomplete dominance. Incomplete dominance is a Non- Mendelian trait as Mendelian traits showed one allele to be completely dominant over the other allele.
