Answer:
A) igneous rock
Explanation:
Igneous rock is formed when molten rock from underground moves to the surface.
There are three types of rock
1. Igneous rock: This is formed when molten rock (magma or lava) cools and solidifies.
2. Sedimentary rock: As the name implies, it is formed by the coming together of small particles such as gravel, sand, silt, or clay.
Metamorphic rock: This is a rock formed from existing rock. It is formed by the gradual disintegration of existing rocks caused by heat or pressure.
Answer:
2) 25%
Explanation:
Let the traits for the black coat color be = BB
Let the traits for the brown coat color be = bb
Let the traits for heterozygous black coat color be = Bb
Now; the question says what is the probability of producing a rabbit with brown coat color from two rabbits that are both heterozygous for black coat color.
This implies that if two rabbits that are both heterozygous for black coat color cross together;
i.e Bb × Bb ;
The offspring will be (BB, Bb, Bb, bb)
BB (rabbits with black coat color) = 1/4
Bb (rabbits that are heterozygous for black coat color) = 2/4
bb (rabbit with brown coat color) = 1/4
Lets focus on ''bb'' ;
bb = 1/4 × 100%
= 25%
