Answer:
Among vertebrates, external fertilization is most common in amphibians and fish. Invertebrates utilizing external fertilization are mostly benthic, sessile, or both, including animals such as coral, sea anemones, and tube-dwelling polychaetes. Benthic marine plants also use external fertilization to reproduce.

Explanation:
Answer:
A 0.015M
Explanation:
Molarity, which refers to the molar concentration of a solution, can be calculated using the formula:
Molarity (M) = mole (n) / volume (L)
Based on the information provided in this question, the solution contains 0.83 g of dissolved KCI.
We can calculate the number of moles of KCl in the solution by using the formula:
Mole = mass ÷ molar mass
Where atomic mass of; K = 39, Cl = 35.5
Molar Mass of KCl = 39 + 35.5
= 74.5g/mol.
Mole = 0.83g/74.5g/mol.
mole = 0.01114
Approximately, n = 0.011mol
Hence, molarity = 0.011mol/0.75L
Molarity = 0.0146
Molarity = 0.015M
Rock cycle- the prices in which rocks undergo in the earths crust, involving igneous instruction, uplift, erosion, transportation, deposits as sedimentary rock.
Tectonic cycle- the movement of large portions of earths crust (plates) the driving forces that move these plates are a combination of events that occurs within the earth.
Water cycle- the path of all water followers as it moves around earth in different states, water vapor, ice, water...
Carbon cycle- series of processes by which carbon compounds are inverted in the environment involving the incorporation of carbon dioxide into living tissue by photosynthesis.
Nitrogen cycle- series of processes by which nitrogen and is compounds are introverted in the environment and living organisms.
Phosphorus cycle-biochemical cycle that describes the movement of phosphorus through the lithosphere, hydrosphere, and biosphere.
