Answer:
-blood type a
-blood type b
-SOMETIMES type o but very rarely.
Explanation:
Each biological parent donates one of their two ABO alleles to their child. A mother who is blood type O can only pass an O allele to her son or daughter. A father who is blood type AB could pass either an A or a B allele to his son or daughter. While a child could have the same blood type as one of his/her parents, it doesn't always happen that way. For example, parents with AB and O blood types can either have children with blood type A or blood type B.
Answer is basalt.
Basalt is fine grained igneous rock which contains 45 to 53% silica and 65% rich is feldspar in the form of plagioclase( silicate rock forming mineral). Feldspar is an abundant rock forming mineral. In basaltic rocks the feldspar is silica.
The basalt rocks contains pyroxene group in its minerals which gives it black color. So rocks containing many dark silicate minerals and plagioclase feldspar have basaltic composition.
