What are volcanoes and describes the type of volcanoes
Pani-rosa [81]
a volcano is a mountain or hill, typically conical, having a crater or vent through which lava, rock fragments, hot vapor, and gas are being or have been erupted from the earth's crust.

There are three main types of volcano - composite or strato,shield and dome. Composite volcanoes, sometimes known as strato volcanoes, are steep sided cones formed from layers of ash and [lava] flows. The eruptions from these volcanoes may be a pyroclastic flow rather than a flow of lava.

In mice, the ability to run normally is a dominant trait. Mice with this trait are called running mice (R). The recessive trait
BlackZzzverrR [31]

Answer:

Parental genotypes: RrBb, RRBB

Offspring phenotype: Running and black hair

Explanation:

Given, Running (R) is dominant over waltzing (r)

Black hair (B) is dominant over brown hair (b)

Parent 1: Heterozygous running, heterozygous black = RrBb

Parent 2: Homozygous running, homozygous black = RRBB

When they mate ( RrBb X RRBB ) :

Gametes produced by RrBb = RB, Rb, rB, rb

Gametes produced by RRBB = RB

Offspring:

        RB          Rb         rB        rb

RB   RRBB    RRBb    RrBB    RrBb

All offspring mice will be running mice and will have black hair because all the four types of genotype at least have one dominant allele for both the genes.
