Answer:
a. By Calculating magnetic reversals.
Explanation:
They determine the age of the ocean floor by examining magnetic fields in the planet Earth.
Answer:
2(h - 8) - h = h - 16 2. 4(x - 3) + 5 = 1 3. 70 = -7(-2 -2z) 4. -2x + 4 = 2(4x-3)-3(-8+4x
Explanation:
2(h - 8) - h = h - 16 2. 4(x - 3) + 5 = 1 3. 70 = -7(-2 -2z) 4. -2x + 4 = 2(4x-3)-3(-8+4x

Explanation:
I think there is one more but not sure hope this helped
(also if spelling is weird sorry I tried)
Answer:
Explanation:
4 types of mutation:
Germline mutations occur in gametes. Somatic mutations occur in other body cells.
Chromosomal alterations are mutations that change chromosome structure.
Point mutations change a single nucleotide.
Frameshift mutations are additions or deletions of nucleotides that cause a shift in the reading frame.
3 more:
Over a lifetime our DNA can undergo changes or 'mutations?' in the sequence of bases?, A, C, G and T.
This results in changes in the proteins that are made.
Mutations can occur during DNA replication if errors are made and not corrected in time.
