Happy homework/ study/ exam!
Answer:
- "Mid oceanic ridge"
Explanation:
<em> Mid-ocean ridges are formed by divergent plate boundaries in the ocean. This is where upwelling magma creates new seabed. A diverging plate boundary occurs when two plates move away from one other. Magma rises from deep beneath the Earth and erupts along these boundaries, forming new crust on the lithosphere. The majority of divergent plate borders are undersea, forming submerged mountain ranges known as oceanic spreading ridges. </em>

The correct answer is: B) H2O
Non-cyclic photophosphorylation is a light reaction and it occurs in the thylakoid membrane and it involves two different chlorophyll photosystem.
Non-cyclic photophosphorylation is a reaction where a water molecule is broken down into 2H+ + 1/2 O2 + 2e− . This process is called photolysis. The 2H+ and 1/2O2 from the water are left out for further use, while two electrons are kept in photosystem II.
The outer covering of a reptile egg, may be flexible, calcified eggshells, while there are some reptiles that has hard eggs. A snake lays a kind of reptile egg that is leathery. A reptile egg may differ from one another, depending on the species.
Answer:
B. A cation
Explanation:
An atom is the smallest indivisible component of a matter including an element. An atom contains three particles called SUBATOMIC PARTICLES (PROTON AND NEITRON in the nucleus and ELECTRON surrounding the nucleus). The proton is positively charged while the electron is negatively charged.
The number of protons and electrons determine whether an atom will be postively charged (cation) or negatively charged (anion). In this question, an atom with 9 protons and 8 electrons will be A CATION because the protons (9) are more than the electrons (8), hence, making it a positively charged atom (cation).
N.B: The cation atom will have a +1 charge
