Answer: Robert Hazen studied carbon cycle and mineralogy.
Explanation:
The following are the implications of Robert Hazen's research work.:
1. He explored that the hydrothermal system present in moons and in some plants are responsible for the development of organic molecules which are responsible for origin of life.
2. Chiral mineral surfaces are responsible for selection and concentration of molecules.
3. He discovered and complied the list of mineral species on the Hadean Earth.
The organism shown is a free-living one that is anchored to the bottom of ponds and streams during one stage of its life cycle. What is the common name of the group to which this organism belongs? bryozoans rotifers cnidarians mollusks there is a picture in the file below.
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
(The Wikipedia entries are for describing.)
If you look at the pictures of all the answers, cnidarians look the most like the organism in the picture shown.

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.

Calculate if 1000 units of energy are available at the producer level of the energy pyramid about how many units are available for first level consumers? Second level consumers? Third level of consumers?
Answer:
first level consumers?- abou 100 units
Second level consumers- about 10 units
Third level of consumers- about 1 unit
Explanation:
Food chain describes the feeding pattern of a group of organisms in an ecosystem. The food chain shows how one organism in one TROPHIC LEVEL feeds on another organism in another. As organisms are being fed on, energy is being transferred.
A food chain always starts with a PRODUCER, which occupies the first and lowest trophic level. It creates the energy transfer as it obtains energy via photosynthetic process. The flow of energy as shown by an energy pyramid is Producer----First level consumer----Second level consumer------Third level consumer.
However, only about 10% of the available energy is transferred and accessible by the next organism. This is because about 90% of the energy has been lost as heat when the organism undergoes metabolic processes. Hence, if 1000 units of energy was present at the producer level, 10/100 × 1000= 100 units will be available to first level consumers.
Also, 10/100 × 100= 10 units of energy will be available to second level consumers and finally 10/100 × 10= 1 unit of energy will be available to talk third level consumer.
Which strategy do geologists use to locate the center of an earthquake? A. They only analyze local data. B. They collect data from seismographs. C. They measure arrival times of surface waves. D. They draw squares on maps for measurements.
Answer:
the answer is (B) "They collect data from seismographs."
Explanation:
i got a 100 on the Quiz "Earthquakes"
The strategy that geologists use to locate the center of an earthquake is they collect data from seismographs. Thus, the correct option is B.
What is an Earthquake?An earthquake may be defined as an activity that involves the unanticipated and brutal shaking of the ground, generally causing huge destruction, as an outcome of movements within the earth's crust or volcanic action.
Geologists utilize an instrument that is known as a seismograph that measures the strength of an earthquake. With the help of this instrument, they find the center of an earthquake on the basis of the highest strength.
Therefore, the strategy that geologists use to locate the center of an earthquake is they collect data from seismographs. Thus, the correct option is B.

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: 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.

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.
