It has more similarity to fossils in layer A than layer D.
The answer is D. Chromosomes contain genes, and genes are made of DNA
Answer:
D. Water is the most abundant atom in Earth’s atmosphere.
Explanation:
An atom can be defined as the smallest particle of an element (e.g., oxygen, hydrogen, etc). Water is a molecule (H2O) because its atoms are connected by molecular bonds (i.e., water is not an atom). Water is the most abundant molecule on the Earth's surface which covers more than 70 percent of the world's surface. A water molecule contains one oxygen (O) and two hydrogen (H2) atoms which are connected by covalent bonds. Water is also a compound known as a diatomic molecule, i.e., a molecule composed of two atoms of the same type.
Nondisjunction could occur during - Anaphase ii
<h3>
What is Nondisjunction ?</h3>
Nondisjunction occurs when the chromosomes do not separate. In this case, gametes are produced with an abnormal number of chromosomes. It is an abnormal number of chromosomes in all cells called aneuploidy or in some cells called mosaicism.
Example ; Down's syndrome, Trisomy of autosomes.
Anaphase is the 3rd stage of cell division process specially after the metaphase in mitosis. In this step sister chromatids gets seperated from each other and pulls towards the cell's ending portion.
specially in Anaphase 2 chromatids splits at the centromere and pulled to the spindle fibres.

hey are oceanic ridges where new ocean floor is created and spreads apart is what they all have in common They are not all at the edges of tectonic plates. Neither the Atlantic Mod ocean ridge nor the Mid Indian ocean ridge are at the edge of tectonics plates. While oceanic or ridges may not be exactly in the middle of a tectonic pate. They CREATE the tectonic even some or part of an oceanic are being subjected.
"...Almost entirely hidden under the sea is a worldwide chain of low mountains with lines of volcanic activity running along their crests. Their worldwide extent was recognized in the mid-20th century, and shortly afterward the mid-ocean ridges were assigned a starring role in the new theory of plate tectonics. The ridges are the divergent zones where oceanic plates are born, spreading apart from the central valley, or axial trough...."
