Answer:
The nucleus contains the protons and neutrons which takes up most of the mass of the atom.
Deoxyribonucleic acid (DNA) is the molecule that can account for both the unity and the diversity of life.
Deoxyribonucleic acid is the molecule that holds genetic data for the growth and functioning of an organism. DNA is made of two connected strands that spiral around each other to form a twisted ladder structure, forming a shape called a double helix. Each strand has a backbone constructed of alternating deoxyribose sugar and phosphate groups. Connected to each deoxyribose is one of four bases, adenine, cytosine, thymine, or guanine, where cytosine bonds with guanine and adenine bonds with thymine. The sequence of these bases along DNA encodes for genetic instructions, like the code for synthesizing a protein or RNA molecule.

Answer:
Throughout the reflection, make sure you have a copy of the Student Guide and your data tables. Complete the paragraph by using the drop-down menus.
In this lab, you determined the relative ages of rock layers using the principles of relative dating. The
✔ law of superposition
says that a rock layer found closer to Earth’s surface is
✔ younger than
a rock layer that is deeper in Earth’s surface. The
✔ principle of cross-cutting relationships
states that intrusions are
✔ younger than
the rock layer they cut across. You also determined the absolute ages of rock layers using a
✔ mass spectrometer
. The data you gathered helped you identify an unknown fossil.
Explanation:
the checked ones are the right answers
The answer is a convergent plate boundary.
