1Answer:
The correct answer is - D. how changes in biodiversity impact an ecosystem.
Explanation:
The water hyacinth is an invasive plant species that rapidly grows and creates a thick layer over the water surface in almost every aquatic ecosystem. The growth of the layer of this species causes problems to the environment, ecosystem, humans, and other species.
These aquatic plants reduce the oxygen level and other nutrients from the ecosystem it is introduced and affect the biodiversity by increasing heavy metals and contaminants.
The layer of this plant inhibits photosynthesis that decreases sugar and energy production and blocks the boat and ship movements and economically as well.
The answer is D because this would help them to survive and is equal to natural selection
Answer:
15 AMU, or 15 daltons.
Explanation:
Typically the number of protons matches that of the electrons. So, there's 8 protons and 7 neutrons. The 8 electrons have a total mass of 8/1000 AMU, not significant enough to be counted. So the total mass is 15 AMU.
