Answer:
coarse-grained texture
Explanation:
Igneous rocks come from magma of volcanos and they cool and end up becoming hard. A perfect example of this is granite, which contains a lot of minerals such as quartz and feldspar. Igneous rocks contain a lot of minerals hence why they have a coarse-grained texture.

Answer:
genes for flower color and edge shape are linked. They do not assort independently.
Explanation:
<u>Available data:</u>
- test cross between a purple-flowered pea plant having serrated leaves and a white-flowered pea plant having smooth edges.
- serrated leaves → dominant trait
- smooth edges → recessive trait
- purple color → dominant trait
- white color → recessive trait
- F1: 4 purple-serrated:1 purple-smooth:1 white-serrated:4 white-smooth.
There are two genes involved in the cross. The expected ratios are 1:1:1:1 because we assume genes assort independently. However, we see a different phenotypic distribution. When phenotypic ratios differ from the expected ones, it means that genes are linked.
To know if two genes are linked in the same chromosome, we must observe the progeny distribution. If individuals, whose genes assort independently, are test crossed, they produce a progeny with equal phenotypic frequencies 1:1:1:1. But if instead of this distribution, we observe a different one, that is that phenotypes appear in different proportions, we can assume that genes are linked in the double heterozygote parent
Answer:
El magma es una roca líquida y semilíquida extremadamente caliente ubicada debajo de la superficie de la Tierra. Este magma puede atravesar agujeros o grietas en la corteza, provocando una erupción volcánica. Cuando el magma fluye o entra en erupción en la superficie de la Tierra, se llama lava. Como la roca sólida, el magma es una mezcla de minerales.
