3. A recent flood in the area has caused many short-term changes to
the ecosystem. Which is a long-term change?
A. Standing water in the streets and sewers
B. Temporary displacement of organisms
C. Permanent change in the landscape
D. Poor water quality in rivers and streams
Answers
Answer:
c
Explanation:
While standing water in the streets and sewers (option A) and poor water quality in rivers and streams (option D) may persist for some time after the flood, they are generally considered short-term changes as they can eventually be remedied through clean-up efforts and restoration programs.
Temporary displacement of organisms (option B) can also be considered a short-term change, as organisms will eventually return to their original habitats once conditions improve.
However, a permanent change in the landscape (option C) such as altered river channels, new water bodies, or changes in topography, can have lasting effects on the ecosystem and its inhabitants. These changes may alter habitat suitability, nutrient cycling, and water availability, which can impact the ecosystem for years or even decades to come.
Answer: C
Explanation:
The landscape could be flooded. Houses and buildings may be restricted.

Which type of selection is shown in the graph above?
A. Disruptive selection
B. Stabilizing selection
C. Disaster Selection
D. Directional selection
Answers
In the given graph, the Evolved Population is showing disruptive selection. Hence, the correct option is A. Disruptive selection.
Stabilizing selection is a form of natural selection where individuals with average phenotypes are more likely to survive and reproduce their number. In this selection, the population tends to maintain a stable phenotype. As shown in the graph, the population is maximum for the population having a moderate length of neck.
Disruptive selection is a type of natural selection where extreme phenotypes are preferred over average phenotypes, leading to an increase in genetic variation and the population becoming more diverse. In this type of selection, the population diverges into two or more distinct phenotypic groups. As shown in the graph, two ranges of the population are favored for having traits for extreme lengths of the neck.

Answers
Answer:Melting.
Freezing.
Evaporation.
Condensation.
Sublimation.
Explanation:
Answer: Examples for the five transformations previously given.
For the first four, we encounter common examples in everyday life, all to do with water:
Freezing - liquid to solid, e.g. water to ice, e.g. making ice cubes.
Melting - solid to liquid, e.g. ice to liquid water, melting ice cubes or snow flakes.
Condensation - gas to liquid, e.g. water vapor (gas) to liquid - water vapor in air (humidity) condenses to form liquid droplets on the outside of a cold beverage glass on a hot humid day; or cloud formation in the atmosphere.
Evaporation - liquid to gas, e.g. liquid water on clothes evaporates as clothes dry on clothesline or in dryer
While water can sublime under certain conditions of temperature and pressure, it is less evident in everyday life. Carbon dioxide however is a more common example.
Sublimation - solid to gas, e.g. "dry ice" disappearing. The visible smoke associated with dry ice is most likely just condensing water vapor in the air as the solid carbon dioxide cools the air.

2) What kind of organisms are found in oceanic trenches? Describe.
3) Explain how an Estuary can support a wide variety of food webs.
4) List out and describe the factors that help meteorologists forecast weather.
Answers
Answer:
1) The cryosphere contains the frozen parts of the planet. This sphere helps maintain Earth's climate by reflecting incoming solar radiation back into space. As the world warms due to increasing greenhouse gases being added to the atmosphere by humans, the snow and ice are melting.
2) Organisms like the Frilled Shark, Giant Spider Crab. Atlantic Wolffish Pair, Fangtooth Fish, Six-Gill Shark, Giant Tube Worms, Vampire Squid, Pacific Viperfish. But there are most likely archaeabacteria which are prokaryotic bacteria or single-celled organisms. A Prokaryotic cell does not contain a nucleus. It only contains one chromosome and is a single-celled organism. It was the only form of life on earth for millions of years. Examples of a Prokaryotic cell are the different types of bacteria present today.
3) Many different types of plant and animal communities call estuaries home because their waters are typically brackish — a mixture of fresh water draining from the land and salty seawater. This unique combination of salty and fresh water creates a variety of habitats. Estuaries are full of decaying plants and animals. This makes the soil of estuaries rich in nutrients. Because the soil is so rich, lots of different plants grow in estuaries. The plants attract lots of different animals to the estuary and those animals attract other animals to the estuary.
4) Temperature, humidity, precipitation, air pressure, wind speed, and wind direction are key observations of the atmosphere that help forecasters predict the weather. These same factors have been used since the first weather observations were recorded. Observational data collected by doppler radar, radiosondes, weather satellites, buoys and other instruments are fed into computerized NWS numerical forecast models. The models use equations, along with new and past weather data, to provide forecast guidance to our meteorologists. The three main factors of weather are light (solar radiation), water (moisture) and temperature.

Day 2 of answering random questions i get asked in my classroom:
How does an Ecosystem Function?
When left to itself, an ecosystem functions like a well–oiled machine. The plants and animals that live in an ecosystem depend on each other for life; this means they are interdependent. Each individual life form does its part to provide for the other lives in the ecosystem community. Let us look at the ocean ecosystem again and start at the beginning. All living things need energy to survive. For example, the seaweed in the ocean gets its energy from the sun. There are fish, like sea carp, that eat the seaweed. The carp get their energy from eating these plants. Then, there are other fish that eat the carp. For example, a sea bass may eat the carp, and a shark may eat the sea bass, and so on. This is called a food chain or a food web. Each part of the chain is connected. Each part depends on the next for the energy to survive.

Answer:
Yes! That is correct.
Explanation:
An ecosystem is one that works on it own, though each individual plays its part.
Scientists have discovered a colony of potential organisms on the Planet Moby and named them "Maxoids." Read the information below that scientists have gathered on Maxoids and decide whether Maxoids are living or nonliving things. Explain how you came to this conclusion.
Through testing and observation, scientists have recorded the following characteristics of Maxoids. Maxoids reproduce via sexual reproduction. One parent carries the Maxoid eggs for 12 weeks before they hatch. After hatching, juvenile Maxoids continue to grow for seven months. To acquire energy for growth, Maxoids consume a peculiar liquid substance native to the planet Moby. The Maxoids' cells use this energy, as well as large amounts of water, to carry out important functions. The Maxoids are sensitive to changes in internal temperature. Sometimes they dig holes and lay in them to cool down if they get too warm.

Answers
Answer:
wood chips, paper, and manure are biomass energy sources.
Explanation:
Biomass energy is energy generated or produced by living or once-living organisms.
Wood chips, paper, and manure are biomass energy sources. The primary form of energy from renewable sources that can be utilised to replace fossil fuels on a long-term basis is biomass.
Energy created or generated by living or formerly living creatures is known as biomass energy. Plants like the aforementioned maize and soy are the most prevalent types of biomass that are utilised for energy. These creatures' energy may be used to generate electricity or be burnt to provide heat. Direct combustion is the primary method of producing most of the power from biomass. In a boiler, biomass is burnt to create high-pressure steam. These turbine blades revolve as a result of the steam flowing over them. Wood chips, paper, and manure are biomass energy sources.

1156 g/L
= ________ kg/mL
Answers
The Answer is 0.001156.
1156 g/L = 1.156 kg/L
Since 1 L is equal to 1000 mL, we can convert kg/L to kg/mL by dividing by 1000:
1.156 kg/L = 1.156/1000 kg/mL
1.156/1000 kg/mL = 0.001156 kg/mL
Therefore, 1156 g/L is equal to 0.001156 kg/mL.
