Virty [35]

Answer:

Big mammals as bears or Mammoths.

Explanation:

Neanderthal had a diet based in different food, for example, there are some evidence that they were feed on nuts, mushroom, and moss. The quantity of veggies were different depending the season and the region of the planet the neanderthals were.  Of course, most of their diet were based in meat, basically  of big animals because the evidence is that they had a digestive system appropriate to eat lean protein.

Studies of the bones and the coprolites showed a ratio of different elements as nitrogen and carbon, the ratio of the heavier element to the lighter, show the relationship among the meat/vegetable diet.

Hope this info is useful.

julia-pushkina [17]

Answer:

Yes

Explanation:

Yes, it is possible. If the woman would have blood AO and the father BO. This would mean there is a 25% chance the child could be OO blood. They would receive an O allele from their mom and an O allele from their dad, in all other cases the O allelle is recessive so AO would be A blood type and BO would be B blood type. AB would be type AB.

    B         O                                      

A   AB     AO                              

O   BO    OO
