Alien Taxonomy Project IN THE YEAR 2525 Humans, after hundreds of years of constant effort, have successfully polluted all bodies of water on Earth. As a result, almost all previously known species of plant, animal, and other life have become extinct. Through natural selection, genetic engineering, and selective breeding programs, a portion of the Earth has been successfully repopulated. The following organisms are all that remain: 1. Photosynthetic sun-basking sharks. Their green fins have chlorophyll to convert sunlight to energy (autotrophs). 2. Chemosynthetic goldfish that convert pollution to food (autotrophs). 3. Aquatic humanoids whose main diet is aqua-wheat and basking sharks. They have fins instead of legs (heterotrophs). 4. Aqua-wheat: one of the few plants that remain, it is similar to algae. 5. Terrestrial Humanoids with 4 arms, their diet consists of butter-roaches and fuzzy hamsters. 6. Tentacled aqua humanoids, they only feed on aqua-wheat and have tentacles for arms and legs. 7. Cockroaches that feed on humanoid waste. 8. Giant Aqua-spiders that live in water and feed on goldfish and basking sharks. 9. Green-haired rats that are photosynthetic. 10. Parasitic mosquitoes that feed off any humanoid 11. Ten-legged fleas that live on the photosynthetic rats and drink blood. 12. Poison Grass - this plant is a hybrid between grass and poison ivy. The plants are toxic to almost everything (autotrophs) 13. Fuzzy hamsters with green hair that use the sunlight to make their food, thought to be related to the rats. 14. Butter-roaches: genetic engineering created these butterfly-like creatures from cockroaches. Butter- roaches eat poison grass. YOUR ASSIGNMENT: 1. As an alien taxonomist, it is your responsibility to classify these existing organism types. Create a taxonomic scheme using only kingdom, phylum, genus, and species. The intermediate categories have been eliminated since the total number of species has been drastically reduced. (Two Kingdoms are recommended). Each new group needs a name and a de

Thus species are grouped within genera, genera are grouped within families, families are grouped within orders, and so on.

The yellow ring inside the bacterial cell represents the bacterial DNA. Why does this structure
disappear by step 3 of the lytic cycle?
Answer:
Explanation The bacterial DNA structure will disappear because of ; The usage of the ribosomes of the bacterial cell by the nucleic acid injected by the virus.
The lytic cycle which is one of the cycles of viral reproduction is the cycle which leads to the breakup of the DNA of the cell ( i.e. destruction of the host cell and its membrane).
Therefore the yellow ring inside the bacterial cell will disappear by step 3 after which the nucleic acid is injected into the host cell by the virus .
Hence we can conclude that the bacterial DNA structure will disappear because of the usage of the ribosomes by the nucleic acid from the virus

1. which of the zones discussed the experiences of photosynthesis.
2. what are the deepest ocean zones.
3. what ocean zone covers more than 50% of the earth's surface
Answer:
1, The top zone is the euphotic or sunlit zone. This is the ocean zone that sunlight penetrates. Because this zone gets sunlight, photosynthesis can occur and plants can grow here. The sunlit zone goes down to about 660 feet.
2. The deepest part of the ocean is the Hadalpelagic Zone. It is also known as the trenches. It goes from 6 000 to approximately 11 000 metres

A company wants to be sustainable and carbon neutral. Which strategy is the best option to meet this company's goal?
O Buy enough carbon credits to be able to release additional emissions.
O Sell carbon credits to increase the value of its carbon emissions.
O Buy carbon offsets by investing in carbon sequestering technologies.
O Sell carbon offsets and carbon credits to maximize carbon emissions.
Buy carbon offsets by investing in carbon sequestration technologies
The carbon neutral company is the operation that eliminates the carbon dioxide produced in the atmosphere. To meet the goal, the company must use carbon sequestering technologies. Thus, option C is correct.
What are carbon sequestering technologies?Carbon sequestering technologies uses various methods to remove the carbon dioxide produced by the machines and system in an organization to reduce its contribution to greenhouse gases.
The captured carbon dioxide is transported via the pipes and is used for other purposes or can be stored underground in the geological structures. To maintain a sustainable and carbon neutral environment carbon sequestration is best as it reduces pollution.
Therefore, option C. the company can be carbon neutral by using carbon sequestration.

if a species has a wide range of tolerance, will it dominate a habitat in low pollution or high pollution? why?
A species with a wide range of tolerance can dominate most habitats due to its ability to adapt.
What is a wide range of tolerance?A wide range of tolerance is the ability for an organism to tolerate low or high levels of abiotic contamination in it's natural habitat. This means that the organisms in question show a high level of adaptability and are able to survive in hostile environments. This allows them to remain dominant in most habitats despite contamination values.
Therefore, we can confirm that a species with a wide range of tolerance can dominate most habitats due to its ability to adapt.

On the island of Hawaii, Keanu notices that the sand on the beach is black, the same color as the rock formations on the island. Keanu realizes the sand used to be part of the rock formations. How did material from the rock formations turn into sand?
Answer:
It turned into sand from erosion. Or to break it down specifically the waves constant crashing on the rocks broke it apart little by little and the pieces of rock that fell into the water were tossed and bashed around even more until they broke into such fine pieces of rock, which is then called sand. The reason that the color of the sand matches that of the surrounding rock is because during this process it doesn't effect the original color of the rock.
Explanation:
Answer:
the answer is the weather
Explanation:
Magma rises to Earth's surface, such as through a volcanic eruption, where it cools and hardens into igneous rock. On the surface, weathering and erosion break down the igneous rock into pebbles, sand, and mud, creating sediment, which accumulates in basins on the Earth's surface
Discuss why photosynthesis is important for humans and life?
Answer:
Here is my answer.
Explanation:
The process of photosynthesis is essential to all living organisms, because it is the primary source of oxygen in the atmosphere. As a result, the carbon cycle could not occur. Plants and oxygen-requiring life would not survive without photosynthesis. Photosynthesis is the process of making food from light, carbon dioxide, and water in the air: It is the main energy source for green plants and trees. Photosynthesis produces oxygen, which we need for survival. Without photosynthesis, the world would have little to no oxygen.

Describe the synthesis of the lagging strand of DNA
Answer:
On the lagging strand, DNA synthesis restarts many times as the helix unwinds, resulting in many short fragments called “Okazaki fragments.” DNA ligase joins the Okazaki fragments together into a single DNA molecule. Helicase opens up the DNA at the replication fork.

The differences between the energy flow and matter cycling depend on the number of trophic levels in the ecosystem.
What do you mean by Ecosystem?The Ecosystem may be defined as the area or place where organisms of different species live and interact with each other in a well-defined way.
The first key difference between energy flow and matter cycling is that the energy flow shows the transmission of energy from one trophic level to the other in the food chain, while matter cycling shows the cycling of elements throughout the living and non-living parts of the ecosystem.
Energy flow always follows a fixed and definite pathway, while matter cycling randomly works in the ecosystem.
As energy moves through an ecosystem, it changes form but no new energy has been synthesized. Matters flow throughout the ecosystem, atoms are rearranged into various other molecules as per requirement but no new matter is created.
Therefore, the differences between the energy flow and matter cycling depend on the number of trophic levels in the ecosystem.
