Answer: the water on or surrounding the surface of the globe, including the water of the oceans and the water in the atmosphere.
Explanation: The hydrosphere includes water that is on the surface of the planet, underground, and in the air. A planet's hydrosphere can be liquid, vapor, or ice. On Earth, liquid water exists on the surface in the form of oceans, lakes and rivers. It also exists below ground—as groundwater, in wells and aquifers.
Answer:
A. What causes some people to be color-blind?
Explanation:
This is something that could be tested with different variables including DNA, or past family medical history.
The correct matching is as follows-
1. (pl. gametangia) an organ of lower plants, some protists and some fungi, that produces gametes- gametangium.
2. the reproductive cell in sexual reproduction- for example, the egg or sperm.
3. gamete-producing organ in animals - gonad.
4. cone-bearing plant - gymnosperm.
5. the condition of having isogametes - isogamy.
Gametangium refers to the specialized organ of algae, fungi, ferns and other plants involved in the production of gametes. A female gametangia is called the archegonia producing the egg cells and the male gametangia is called the antheridia producing the sperm cells.
Sexual reproduction is characterized by the production and fusion of the male and female gametes called the sperm and the egg respectively.
The gamete producing organ in animals is called the gonads. It is the testis in the male and the ovary in the female.
Gymnosperms are naked seeded plants. The scales or leaves modified to form the male and the female cones.
Isogamy is a type of sexual reproduction that involves the gametes of similar morphology with similar size.

The overwhelming amount of seismic activity particularly happens along convergent plate boundaries. In particular, reverse or thrust faults occurs on convergent plate boundaries.Converging plate boundaries are classified into two types of activities.First is the subduction boundary where the oceanic lithosphere is pressured beneath a continental plate or oceanic plate thus it overrides the other plate then slowly directed to the mantle where it will become a magma. Second is the collisional boundary where earthquakes occur because of the continental crust squeezed together then plates are pushed upwards.Reverse faults are correlated to earthquakes with magnitude of 8 or more.Hence, earthquakes of magnitude 8 or more are considered powerful and mega thrust earthquakes.</span>
