Answer:
External fertilization usually occurs in aquatic environments where both eggs and sperm are released into the water. After the sperm reaches the egg, fertilization can then take place. Most external fertilization happens during the process of spawning where one or several females release their eggs and the male(s) release sperm in the same area, at the same time. The release of the reproductive material may be triggered by water temperature or the length of daylight. Nearly all fish spawn, as do crustaceans (such as crabs and shrimp), mollusks (such as oysters), squid, and echinoderms (such as sea urchins and sea cucumbers). Pairs of fish that are not broadcast spawners may exhibit courtship behavior. This allows the female to select a particular male. The trigger for egg and sperm release (spawning) causes the egg and sperm to be placed in a small area, enhancing the possibility of fertilization.

Which organisms are eukaryotes?
animals
plants
archaea
fungi
Answer:
Bacteria and archaea are prokaryotes, while all other living organisms — protists, plants, animals and fungi — are eukaryotes.
Explanation:
Among the mentioned types of organisms, animals, plants and fungi are eukaryotes and archaea are prokaryotes.
What are eukaryotes?The organisms having a true membrane-bound nucleus with membrane-bound organelles in their cell are called eukaryotes. Eu - true, karyon - nucleus. So the word eukaryotes mean the organism having a true nucleus.
In the 5 kingdom system of classification, every kingdom except Monera consists of eukaryotes. Monera consists of unicellular prokaryotes and this includes two groups of organisms, they are archaea and bacteria.
Protista, fungi, Plantae and Animalia kingdoms consist of eukaryotes. Protists are unicellular eukaryotes and the rest are multicellular eukaryotes.
Kingdom fungi include saprophytic multicellular eukaryotes. The kingdom Plantae includes photosynthetic multicellular eukaryotes. The kingdom Animalia includes heterotrophic multicellular eukaryotes.
Therefore, the correct options are animals, plants and fungi.

Where does the energy that powers the nitrogen cycle come from?
Answer:
When nitrogen is absorbed by the soil, different bacteria help it to change states so it can be absorbed by plants. Animals then get their nitrogen from the plants. Fixation - Fixation is the first step in the process of making nitrogen usable by plants. They absorb nitrates from the soil into their roots.

A city is considering switching to geothermal power for their electricity needs. Which of the following is an advantage of this plan?
1. It is commonly used across the entire United States.
2.It uses less land area than gas power plants.
3.It uses water to power large turbines.
4.It in inexpensive to build.
It uses water to power large turbines.
Geothermal power taps on the energy of natural steam from the earth's lithosphere.
Explanation:
The heat from deep in the the lithosphere heats up underground water into high-pressure steam trapped in within the rocks. Boreholes are sunk to tap on the potential energy of this high-pressure steam to turn large dynamo turbines that convert the steam energy into electricity.
The biggest advantage, moreover, is the fact that this method of electricity generation does not emit greenhouse emissions as compared to gas plants that burn hydrocarbons that release CO₂.
