1. List a short-term event and describe the impact to organisms.
2. List a long-term event and describe the impact to organisms.
Answer:
A short-term environmental change is drought, smog, flooding, volcanic eruption, blizzards, and pollution this could happen in anyone of the food webs. That may effect how they will end up having to have to adapt to their environment so that they can continue to live there and not die off.Explanation:

Short-term events and their impact on organisms: A wildfire is a short-term event that can have a significant impact on organisms and Long-term events and their impact on organisms: Climate change is a long-term event.
What are short-term events and long-term events?Wildfires are a natural occurrence in many ecosystems, but when they occur at an unnatural frequency or intensity, they can have a significant impact on organisms. The immediate impact of a wildfire on animals can be devastating, especially for those that cannot escape in time, and this is a short-term event. Climate change is a long-term event that has been caused primarily by human activities, such as burning fossil fuels, deforestation, and agriculture. As global temperatures continue to rise, habitats are shifting and becoming less suitable for certain species.
Hence, a wildfire is a short-term event that can have a significant impact on organisms, and climate change is a long-term event.

What impact does bleached coral have on the ecosystem in which it lives?
Answer:
Bleached corals are likely to have reduced growth rates, decreased reproductive capacity, increased susceptibility to diseases and elevated mortality rates. Changes in coral community composition can occur when more susceptible species are killed by bleaching events.
Bleached corals are more likely to have slower growth rates, fewer eggs, a lower ability to resist disease, and higher mortality rates.When more vulnerable species are wiped out by bleaching events, changes in the composition of the coral ecosystem might result.
What is coral reef ?Coral reefs are the most diverse ecosystem in the world providing habitat to aquatic livings. The coral pulps are made of calcium carbonate. Coral bleaching and the related mortality not only harm coral populations, but also fish communities, human communities, and other living things that depend on coral reefs and associated fisheries for their survival.
The species that rely on coral communities, like as fish and invertebrates that need living coral for food, shelter, or spawning grounds, are also impacted by changes to these communities.
When corals die as a result of coral bleaching, there may be changes in the abundance and makeup of reef fish assemblages. When corals perish due to bleaching, genetic and species diversity may be reduced.

Which type of rock has a coarse texture due to slow cooling in magma chambers?
extrusive
intrusive
metamorphic
sedimentary
Answer:
Intrusive
Explanation:
The intrusive rocks are also called as the plutonic rock. It is also considered as an igneous rock like granite and diorite. The rock which has a coarse texture due to slow cooling in magma chambers is intrusive rock. The correct option is B.
What is intrusive rock?The intrusive rocks are formed when the magma penetrates some of the existing rock structures, it crystallizes and solidifies below the surface to produce intrusions and coarse texture. Hence the name called intrusive rocks.
There are two ways in which the igneous rocks can be formed which are the intrusion and extrusion of magma. When the magma is passed through the intrusions inside the Earth's crust it forms the intrusive rocks. Granites, sills, etc. are examples.
The intrusive rocks are highly characterized by the size, shape and texture of the crystals.
Thus the correct option is B.

What is equilibrium? Are molecules still moving at equilibrium?
Answer: Since the molecules are still in motion, but an equilibrium has been established, the end result of molecular diffusion is called a "dynamic equilibrium". In a phase with uniform temperature, absent external net forces acting on the particles, the diffusion process will eventually result in complete mixing.

What is primarily responsible for holding two nitrogen atoms together in a molecule of nitrogen gas?
O A. Ionic bonds
O B. covalent bonds
