explain why the offsrping with Gg genes for pod color look the same as a pea plant with GG genes for pod color
ArbitrLikvidat [17]
This is more a biology question but anyway....
 G = the dominant gene aka. the one that is most likely to be seen because it is stronger than g. GG and Gg will both show the dominant gene's characteristics.

 g = the recessive gene. The only way this one's type can be seen in gg form with no dominant gene to overpower it

Which family on the periodic table contains elements that already have the octet in their valence energy level? a:family 1 b:fam
Scilla [17]

<u><em>Answer:</em></u>

  • Correct option is D. Family 18

<u><em>Explanation.</em></u>

The elements of group 18 of periodic table are called as noble gases. They are stable because they have complete valence shell electrons. So there octet rule is satisfied.

The elements of noble gases are

  • He
  • Ne
  • Ar
  • Kr
  • Xe
  • Rn

Oxidation unit test
3241004551 [841]

In this case, according to the given information about the oxidation numbers anf the compounds given, it turns out possible to figure out the oxidation number of manganese in both MnI2, manganese (II) iodide and MnO2, manganese (IV) oxide, by using the concept of charge balance.

Thus, we can define the oxidation state of iodine and oxygen as -1 and -2, respectively, since the former needs one electron to complete the octet and the latter, two of them.

Next, we can write the following x, since manganese has five oxidation states, and it is necessary to calculate the appropriate ones:

Mn^xI_2^-\\\\Mn ^xO_2^{-2}

Next, we multiply each anion's oxidation number by the subscript, to obtain the following:

Mn^xI_2^-\rightarrow x-2=0;x=+2\\\\Mn ^xO_2^{-2}\rightarrow x-4=0;x=+4

Thus, the correct choice is Manganese has an oxidation number of +2 in Mnl2 and +4 in MnO2.
