4. Compare the two examples of changes in beetle populations. Which of the two scenarios is an example of evolution? Defend your answer with an explanation.
Answer:
The second scenario, "Beetles of a different color", is an example of evolution.
Explanation:
Since evolution is defined as a change in gene frequency overtime, over generations, it is in the second example that we see such a phenomenon taking place. Brown beetles have become more common as opposed to the green beetle population that were the ancestors in this case.
Hope that answers the question, have a great day!

Was it beneficial or harmful for the Chthamalus barnacle to add the Balanus barnacle? Explain.
Answer:
It was it harmful for the Chthamalus barnacle to add the Balanus barnacle.
Explanation:
The principle of competitive exclusion says that two different species that share the same niche can not live in the same place. If these species have the same requirements, they can not coexist. Two species can not coexist indefinitely on the bases of the same limited resource.
When two competing species coexist, this is because of niche partitioning or niche differentiation. If there is not any differentiation between them, the dominant species displaces the weak species.
In the exposed example, Chthalamus can live in the upper intertidal zone, where Balanus can not live because they can not tolerate desiccation. Balanus live in the lower intertidal zone, where Chthalamus can not live because of its vulnerability to predation. But these two species compete for the middle intertidal zone, where they can both live. Balanus excludes Chthalamus because the first species is much bigger and grows faster than the second one. So the middle intertidal zone is only inhabited by Balanus.
The area occupied by Chthalamus is smaller in the presence of Balanus. In the absence of Balanus, Chthalamus can live in a bigger area, occupying the middle intertidal zone.

Can you write a two-page paragraph explaining invasive species please? Thank you.
Answer:
Invasive species, also called introduced species, alien species, or exotic species, any nonnative species that significantly modifies or disrupts the ecosystems it colonizes. Such species may arrive in new areas through natural migration, but they are often introduced by the activities of other species. Human activities, such as those involved in global commerce and the pet trade, are considered to be the most common ways invasive plants, animals, microbes, and other organisms are transported to new habitats.
Most introduced species do not survive extended periods in new habitats, because they do not possess the evolutionary adaptations to adjust to the challenges posed by their new surroundings. Some introduced species may become invasive when they possess a built-in competitive advantage over indigenous species in invaded areas. Under these circumstances, new arrivals can establish breeding populations and thrive, especially if the ecosystem lacks natural predators capable of keeping them in check. The ecological disruption that tends to follow such invasions often reduces the ecosystem’s biodiversity and causes economic harm to people who depend on the ecosystem’s biological resources. Invasive predators may be so adept at capturing prey that prey populations decline over time, and many prey species are eliminated from affected ecosystems. Other invasive species, in contrast, may prevent native species from obtaining food, living space, or other resources. Over time, invading species can effectively replace native ones, often forcing the localized extinction of many native species. Invasive plants and animals may also serve as disease vectors that spread parasites and pathogens that may further disrupt invaded areas.Invasive species are capable of causing extinctions of native plants and animals, reducing biodiversity, competing with native organisms for limited resources, and altering habitats. This can result in huge economic impacts and fundamental disruptions of coastal and Great Lakes ecosystems.

Answer:
false
Explanation:
why/how is biodiversity essential to the health of an ecosystem
Answer:
Biodiversity is the amount of variety of life on Earth.
Explanation:
Biodiversity boosts ecosystem productivity where each species, no matter how small, it has an important role to play.
For example,
a larger number of plant species means a greater variety of crops. Greater species diversity ensures natural sustainability for all forms of life.
Because it provides a wide variety of ecological services essential to both ecosystem function and human well-being, biodiversity is important to the health of an ecosystem.
What is Biodiversity?The term "biodiversity" describes the range of living things in an ecosystem, such as plants, animals, fungi, and microorganisms, as well as the genetic diversity found within each species.
Here are some justifications for why ecosystem health depends on biodiversity:
1. Nutrient Cycle: The ability of an ecosystem to cycle nutrients depends on biodiversity.
2. Temperature control: By absorbing carbon dioxide and generating oxygen through photosynthesis, biodiversity helps regulate temperature.
3. Soil health: Biodiversity is essential for the preservation of healthy soil.
4. Controlling pests and diseases in ecosystems: Biodiversity can help in managing pests and diseases.
5. Benefits to the Economy: Humans benefit economically from biodiversity in a number of ways, including access to food, medicine, and other natural resources.
Therefore, biodiversity is important for the health of ecosystems, and its loss can have serious detrimental effects on both ecosystem functioning and human well-being.

Answer: Glaze storm
Explanation:
A storm is a disturbed weather condition which is developed due to unstable wind currents. The center of wind currents are in low pressure whereas the surrounding are at high pressure. This condition forms clouds called cumulonimbus.
A glaze storm can be defined as a precipitation event in which the ice coating is formed on the exposed objects by the freezing of supercooled water deposited by the rain or fog on the surface.

SUBME
The given image represents the oxygen cycle. The correct option is C.
What is oxygen cycle?The biogeochemical cycle that describes the movement of oxygen within and between the Earth's atmosphere, biosphere, and lithosphere is known as the oxygen cycle.
Oxygen is constantly produced and consumed in various parts of the cycle, with photosynthesis, the process by which green plants and some bacteria convert carbon dioxide and water into organic compounds and oxygen, serving as the ultimate source of oxygen.
The oxygen produced during photosynthesis is released into the atmosphere and used by living organisms for respiration, which is the breakdown of organic compounds to release energy and carbon dioxide.
Human activities, such as the burning of fossil fuels and deforestation, can have an impact on the oxygen cycle by altering the balance of carbon dioxide and oxygen in the atmosphere.
Thus, the correct option is C.

Why is water pollution a concern if water is continuously cycled through Earth’s systems?
Water pollution is still a concern, even though its cycled through the Earth's system continuously, for many reasons. Firstly, people still continue to dump toxic chemicals, and plastic/ garbage into the water. Plastic doesn't decompose, it continues to sit and pollute the ocean unless it is cleaned up. Then there are also the chemicals. Some of these chemicals don't dissipate, or clear out for many years. There is also oil that has been spilt into the ocean. Even though it was many years ago, it still lingers in the ocean, and is very difficult to clean up. Secondly, there are bacteria and algae that lives in the water, which makes it very harmful for us if not cleaned out. The Earth's system is unable to keep these organisms out of the water. Thirdly, there is constantly water, even though water goes through the cycle, there is still unfiltered polluted water that stays, and then pollutes the filtered water.

Answer:
cnidarians
Explanation:
bryozoan - "Bryozoa are a phylum of aquatic invertebrate animals. Typically about 0.5 millimetres long, they are filter feeders that sieve food particles out of the water using a retractable lophophore, a "crown" of tentacles lined with cilia." -Wikipedia
rotifers - "The rotifers, commonly called wheel animals or wheel animalcules, make up a phylum of microscopic and near-microscopic pseudocoelomate animals." -Wikipedia
cnidarians - "Cnidaria is a phylum under kingdom Animalia containing over 11,000 species of aquatic animals found both in freshwater and marine environments: they are predominantly marine. Their distinguishing feature is cnidocytes, specialized cells that they use mainly for capturing prey. Their bodies consist of mesoglea, a non-living jelly-like substance, sandwiched between two layers of epithelium that are mostly one cell thick.
" -Wikipedia
mollusks - "Mollusca is the second-largest phylum of invertebrate animals after the Arthropoda. The members are known as molluscs or mollusks. Around 85,000 extant species of molluscs are recognized. The number of fossil species is estimated between 60,000 and 100,000 additional species. The proportion of undescribed species is very high." -Wikipedia
