according to shape, size, and their relationship to surrounding layers of rock
Explanation:
Scientists classify intrusive features according to their shape, size and relationship to surrounding layers of rocks.
Intrusive igneous features are the sills, di/kes, batholith, laccoiith, lopolith e.t.c
- When magma cools and solidifies within the earth crust, they form intrusive igneous rocks.
- Intrusive igneous rocks differs from one another in their shape, size and relationship to surrounding rocks.
- For example, batholith is a large intrusive body that extends for several kilometers in the earth surface.
- Sills and di/kes are smaller bodies. Sills forms parallel to orientation of rocks in an area. Di/kes are known to cut across the orientation.

Answer:
U A G C C A U C G G A U C C G A U
Explanation:
In DNA, A=T, C=G, and vice versa. RNA has U instead of T. So dna to rna: adenine = uracil, thymine = adenine, cytosine = guanine, and guanine = cytosine.
Answer:
Ca(OH)2 --> Ca2+ + 2OH-
Explanation:
Calcium hydroxide is sparingly soluble in water. It dissociates to give the following:
The net ionic equation :
Ca(OH)2 + H2O --> Ca2+ + 2OH- + H2O
Since, H2O doesn't affect the overall reaction, therefore;
Ca(OH)2 --> Ca2+ + 2OH
