Compared to rodents, rabbits have an extra pair of incisors and other skeletal structures that are different, scientist can conclude from this observation that they are serially homologous.
<h3>What are serially homologous?</h3>
Serial homologous organs or structures are those that are structurally similar but have been modified to perform distinct functions.
As rodents and rabbits both have some similar functions and some changes in the skeletal structure, so that they both are serially homologous.
Hence scientist conclude that rodents and rabbits are serially homologous animals.

Answer:
NiO
Explanation:
Firstly, we need to know the mass of oxygen used up. This is the difference between the mass of the nickel and the mass of the oxide. This is : 2.852 - 2.241 = 0.611g
Now we convert these masses to mole by dividing by their atomic masses. The atomic mass of oxygen is 16 while that of nickel is 59
O = 0.611/16 = 0.0381875
Ni = 2.241/59 = 0.037983050847458
The next thing is to divide each by the smaller number of moles, which is that of the nickel.
O = 0381875 /0.037983050847458= 1
Ni= 0.037983050847458/0.037983050847458= 1
The empirical formula is thus NiO
Answer:
The correct answer would be A.
Answer: 50%
Explanation:
The number of electron pairs are 2 for hybridization to be 
and the electronic geometry of the molecule will be linear.
1. percentage of s character in sp hybrid orbital =
2. percentage of s character in 
hybrid orbital =
3. percentage of s character in 
hybrid orbital =
Thus percentage of s-character in an sp hybrid is 50%.
the answer is 360 g H2O with a 90.3 yeild percentage
