An overaccumulation of dinoflagellates causes a _______, which can contaminate shellfish and make them unfit for human consumption.
A. rose water
B. red tide
C. crimson summer
D. scarlet wave
Answer: B. Red tide
Explanation:
Answer: B. red tide
Explanation:
Red tide is a phenomena that is caused by algal bloom specifically due to the growth and abundance of unicellular algae called as dinoflagellates and diatoms. These organisms impart red color to the coastal waters. Such kind of algal blooms release toxins in the water. They deplete the concentration of oxygen in the water body.
The shellfish consume these small unicellular organisms as they filter large amount of water. The shellfish population accumulates large amount of toxins on consumption of these small organisms. The shellfish are harvested and consumed by the human population can make them sick and may lead to mortality of large population.

Answer:
Where is the story that goes with it?
Answer:
I mean this has to be referencing Jurassic World right? He was never keen to letting them out in the first place.
Explanation:
In the first movie he explains how the only reason he has a bond with them was raising them from young. This is hinted in flashbacks during both movies. They're extremely intelligent as we noticed in the first few movies of the entire series. While that may be true there is no real reason for them to be out in the field as they are natural killers not trained (this was even clearly exampled in the last movie with laser targeting yes it worked for a second but when it was free it went for everything in it's path.)

Mung beans planted early in the spring produce flowers at the same time as mung bean plants planted early in the summer due to the A) age of the plant. B) length of darkness. C) amount of moisture. D) amount of fertilizer.
C) amount of moisture
Answer: Option B
Explanation:
The mung beans is planted early in the spring season and produce flowers at the same time if it is planted in the early summer.
This is so because the time for which the seeds need sunlight is limited. The beans will get energy and light in the same amount even if it is planted at the starting of the summer season,.
This is due to the darkness that the beans receive when it is not being exposed to the sunlight and outer environment.
Hence, the correct answer is option B
How does a food web show relationships between organisms in a food web and what are some strengths and weaknesses in food web models?
Answer:
Producers, or autotrophs, make their own organic molecules. Consumers, or heterotrophs, get organic molecules by eating other organisms.
A food chain is a linear sequence of organisms through which nutrients and energy pass as one organism eats another.
In a food chain, each organism occupies a different trophic level, defined by how many energy transfers separate it from the basic input of the chain.
Food webs consist of many interconnected food chains and are more realistic representation of consumption relationships in ecosystems.
Energy transfer between trophic levels is inefficient—with a typical efficiency around 10%. This inefficiency limits the length of food chains
Explanation
Hope this helps
Final answer:
Food chains and food webs illustrate feeding relationships and energy flow in ecosystems, with food chains being linear and food webs displaying interconnected networks.
Explanation:
Food chains and food webs both depict feeding relationships in ecosystems, showing the flow of energy and matter. While food chains are linear sequences of who eats whom, food webs are interconnected networks that display multiple feeding relationships among organisms.
The strengths of food chains lie in their simplicity and clarity in illustrating one specific path of energy transfer. On the other hand, food webs offer a more comprehensive view of an ecosystem, showcasing the complexity of interconnections between various organisms.

How can you determine that a star is about to turn into a red giant?
Answer:
When the inner core shrinks and the outer atmosphere expands thereby giving red color to the star.
Explanation:
When the hydrogen with in the core of a star gets exhausted, the nuclear reactions taking place in the inner core move outwards towards the atmosphere of the star in search of fuel. Due to this, the star expands and become cool and red. This process continues till the star convert into red giant and all the available fuel (hydrogen) is consumed.
Due to expanding atmosphere, the inner core starts shrinking due to gravity. The pressure and temperature also increases in the middle till nuclear fission starts again but this time it will use helium instead of hydrogen.
You can determine a star is about to turn into a red giant when it is in its main sequence stage where it is expected to continuously fuse hydrogen to helium which generates light and heat, but stops fusion as a result of running out of hydrogen fuel in its core.
Further ExplanationThe moment fusion stops, gravity takes places and this will lead to the compression of the star into a smaller and tighter unit. Hence it stops being a main sequence star, and automatically becomes a Red Giant.
A star usually commences its existence as huge ball of gas, and pass through various stages in its lifetime to end as its remnants. The life cycle of a star is in seven stages which are: the Giant gas cloud stage, the Protostar stage, the T-Tauri stage, the Main sequence star stage, the evolution into Red Giant stage, the fusion into Heavier Elements stage and the Supernovae stage.
Basically, a red star giant is a dying star. A star spends most of its lifetime as a main sequence star before transforming into a red giant. When a main sequence star exhausts its hydrogen, it is ready to become a red giant, and as such, temperature within and the outer of the stellar core begins to increase as a result of the collapse of core propelled by gravity.

Which of these can be used to see how climate has changed over time?
Ice cores
Tree rings
Both of these
Both ice cores and tree rings are instrumental in studying past climate changes, with ice cores revealing atmospheric conditions and tree rings indicating climatic variations through their width and density.
Both ice cores and tree rings can be used to see how climate has changed over time. Ice cores are samples from polar ice that provide a record of past climates, revealing information such as atmospheric gas concentrations and particulates that reflect volcanic eruptions and human activities. Tree rings, on the other hand, can show variations in climatic conditions based on their width and density. Wide rings indicate wetter and warmer years, while narrow rings suggest drier and colder periods. Because some trees can live for thousands of years, their rings can inform us about regional climate changes over long time periods.
Tobin learns that using aluminum cans and plastic bottles can damage the environment. He begins writing the proposal below to suggest a way to reduce their impact.
People should be worried about the environmental effects of using cans and bottles. People use about 200 billion aluminum cans and 500 billion plastic bottles each year. To meet this demand, many new aluminum cans and plastic bottles are made each year. Making new aluminum cans requires minerals and making new plastic bottles requires fossil fuels. Getting these materials from the Earth can damage the environment and cause pollution.
Recycling cans and bottles decreases the amount of new materials that are needed to make more of them. About 68% of aluminum cans are recycled, but only about 7% of plastic bottles are recycled. Many of these plastic bottles end up in landfills or in the ocean.
Which argument would best complete Tobin's proposal?
A.
Encouraging people to use more aluminum is one of the best ways to protect the ocean.
B.
Encouraging people to recycle plastic bottles is the best way to protect the environment.

An adaptation helps an organism to survive. i.e, option A is correct.
What is camouflage?Camouflage, also known as cryptic coloring, is protection or strategy used by organisms to hide their presence and mix in with their surroundings. Camouflage is a technique used by organisms to conceal their presence, appearance, and mobility. This allows predators to sneak up on prey and prey to avoid predators.
Polar bears have white fur to help them blend in with their surroundings. In Arctic conditions, their coat is so perfectly camouflaged that it can be mistaken for a snow drift. Surprisingly, the polar bear's coat lacks white pigmentation; in reality, the polar bear's skin is black and its hairs are hollow.

two new species of plants were introduced into an area that was a low in available nitrogen compounds in the soil. one formed modules and one did not. which species would you reasonably expect to grow more robustly? explain.
Final answer:
The plant species with nodules would grow more robustly due to its relationship with nitrogen-fixing bacteria, which enriches the soil with nitrogen compounds crucial for plant growth in nitrogen-poor environments.
Explanation:
In a low nitrogen environment, the plant species that formed nodules would be expected to grow more robustly. This is because nodules are the result of a symbiotic relationship between the plant and nitrogen-fixing bacteria such as rhizobia. These bacteria fix atmospheric nitrogen, which is otherwise unavailable to plants, converting it into ammonia and other compounds that plants can use for growth.
Nitrogen fixation is especially crucial in nitrogen-poor soils, where the availability of fixed nitrogen limits plant growth. The plant species with nodules would thus have a distinct advantage as it can access a constant supply of nitrogen directly from the atmosphere, thanks to its symbiotic partners. In contrast, the non-nodule forming plant would depend solely on the limited nitrogen compounds already present in the soil or those being slowly released through other processes, which may not suffice for robust growth.
As has been observed historically in agricultural systems and ecosystems disrupted by invasive nitrogen-fixing species, the ability to establish a symbiotic relationship with nitrogen-fixing bacteria significantly enhances the plant's growth potential and ecological success in nitrogen-limited environments.

Many cows are given antibiotics as part of their regular diet. It has been determined that these antibiotics can be detected in the milk of these cow. How do you think this might effect the yogurt making process?
Answer:
When providing antibiotics to cows, it provides unspecified chemicals that can range to many different issues. These chemicals can both affect the cow and its produce. Asserting the fact into yogurt, this antibiotic(dependant on its chemical) can affect the product within both positive and negative ways. If the chemical is positive, it can increase mass,taste and even quality. If it is negative, it can create a bad taste,bad quality and even transmit diseases!
Antibiotics in a cow's diet can lead to antibiotic-resistant bacteria. These resistant bacteria could affect the probiotic bacteria used in the yogurt-making process potentially hindering the fermentation and production of yogurt.
Explanation:Antibiotics given to cows can be detected in their milk which might affect the yogurt production process. These antibiotics could potentially select for antibiotic resistance in bacteria, including those involved in yogurt fermentation. The routine use of antibiotics in livestock feed can cultivate bacteria resistant to antibiotics. This could thereby affect the bacteria that is necessary for the yogurt-making process.
Furthermore, these resistant bacteria may produce mobile genetic elements, transferring resistance genes amongst each other, and these could also impact the probiotic bacteria used in yogurt production. Probiotics are beneficial bacteria integral to human gut health and to the creation of yogurt. The likely outcome would be a disruption in the fermentation process, possibly hindering the production of yogurt.

Answer:
You did not provide the Venn Diagram but maybe this would help you out.
There are ways molecules move in and out of the cell membrane and they can be categorized as Passive or Active transport.
Here are some descriptions of passive transport, active transport, and both.
Active Transport Both Passive Transport
-Uses energy -Moves across - form of diffusion
-Moves from low cell membrane - Moves from high
to high concentration to low concentration
Hopefully, this will help you fill in your Venn Diagram
The label that belongs in the region marked X in the Venn diagram that compares active transport and passive transport across the cell membrane is Uses energy to work.
In the Venn diagram comparing active transport and passive transport across the cell membrane, the region marked X corresponds to the label "Uses energy to work."
This label accurately reflects the key characteristic of active transport processes.
Active Transport:
Active transport is a cellular process that requires energy to move molecules against their concentration gradient, from an area of lower concentration to an area of higher concentration.
This energy is typically derived from ATP (adenosine triphosphate).
In active transport, proteins embedded in the cell membrane, such as pumps and carriers, actively transport ions or molecules across the membrane, promoting the movement against the natural flow.
Passive Transport:
On the other hand, passive transport refers to the movement of molecules across the cell membrane without the input of energy.
This process occurs along the concentration gradient, from an area of higher concentration to an area of lower concentration.
Passive transport mechanisms include simple diffusion, facilitated diffusion through channel or carrier proteins, and osmosis.
The label "Uses energy to work" appropriately characterizes the unique feature of active transport, distinguishing it from passive transport mechanisms that do not require additional cellular energy for the movement of molecules across the cell membrane.
