Answer:
B
Explanation:
The role the ultrafine particles play in dirty air is that they can worsen symptoms for people with breathing difficulties. The correct answer is b).
What are ultrafine particles?The term "ultrafine particles" (UFPs) refers to particles with a dimension of less than micrometers and more than 0.1 micrometres (100 nanometers), also known as nanoscale particles. The majority of the ultrafine particles are found on motorways and are mostly produced by vehicle emissions.
It has been demonstrated that ultrafine pollution particles may play a crucial role in igniting extra pathways or inflammation, which worsens asthma disease. The ultrafine particles released by motor vehicles and other sources of combustion are covered with an organic chemical coating that can be inhaled.
By oxidizing cells and tissues, these substances create free oxygen radicals that activate the immune system in the lung. For those who have asthma, oxidation exacerbates the allergic inflammation in their lungs.
Therefore the correct option is b).

1. Would the pollution problems caused by cars and trucks be completely solved if they all became electrically powered overnight?
2. Name one challenge we need to overcome by using solar panels
Answer:
1.This doesn't help COMPLETELY get rid of pollution. It might help lessen the pollution, but it definitely won't solve it, because there are also other things that cause pollution.
2.The main problem with solar power that has stifled its use is the fact that energy production only takes place when the sun is shining. And it won't be beneficial to the countries that aren't really close to the equator ( the middle east) and that might be a problem cause there just might not be enough energy/electricity.
Some students looked at pond water with a microscope. They saw prokaryotic and eukaryotic
organisms. The diagram shows one of the many organisms they saw.

Explanation:
An enzyme known as rubisco enables plants to use large amounts of
carbon dioxide. This enzyme is most likely active in the
O (1) nucleus
O (2) vacuoles
O (3) mitochondria
O (4) chloroplasts
The enzyme rubisco is most likely active in the chloroplasts.
• In the chloroplasts of the plants, the enzyme rubisco is present.
• It takes part in fixing atmospheric carbon dioxide at the time of photosynthesis and in oxygenation of the resulting compound at the time of photorespiration.
• Rubisco is the name given to the enzyme ribulose-1,5-bisphosphate, which catalyzes the carbon dioxide entry into the photosynthetic metabolism, monitors the pool sizes of essential photosynthetic intermediates, and provides acceptor molecules, which consume the products of the light reactions of photosynthesis.
Thus, option 4, that is, chloroplasts is correct.

Refer to the Biochemistry in Focus section of your text for this chapter to answer this question. A mutation in Complex I decreases the efficiency of the electron transport chain. However, not all components of the electron transport chain are affected by this mutation. Which component of the electron transport chain will remain unaffected by a mutation in Complex I
Answer:
Complex II
Explanation:
The electron transport chain refers to a group of electron transporters embedded in the inner mitochondrial membrane that transfer electrons from electron donors to electron acceptors which undergo redox (reduction and oxidation) reactions. The energy released during the transfer of electrons is coupled to the transfer of protons (H+) from the mitochondrial matrix into the intermembrane space, generating an electrochemical gradient that is then used to synthesize ATP. Complex I and Complex II are membrane-bound complexes that act as mitochondrial redox carriers. Complex I is a proton pump that uses energy from the electron transfer chain to pump protons, while Complex II sends H+ onto Complex III in the form of the reduced ubiquinol. Complex I receives electrons from NADH and transfers them to ubiquinone, while Complex II directly receives the redox cofactor FADH2 that does not pass through Complex I.
Select an organism of your interest! Research to see if that organism undergoes asexual or sexual reproduction. Describe why that type of reproduction is advantageous for your organism.
Answer:
Many fungi and plants reproduce asexually. Some plants have specialized structures for reproduction via fragmentation.
Explanation:
This allows them to adjust to conditions in the environment. They can spread quickly through asexual reproduction when conditions are stable. They can increase their genetic variation through sexual reproduction when conditions are changing and variation may help them survive.
Reproduction is a method by which the genetic material from the parent is transferred to offspring and in this way the character and traits are passed from generations.
I will select plants for my research purpose.
Plants are species that reproduce sexually. They have male and female organs that produce cells for reproductions. They sexually reproduce through the process of pollination.
This method of reproduction helps in genetic variation and in forming recombinant species that are more variant.
This variation helps the plant species to survive better compared to less competent species.
Sexual reproduction is beneficial for plants as it increases varieties and helps plants in fighting against a common population disease.

Use the information gathered in the A Three Point Test Cross animation to answer the question. Genes H and K are linked and are known to be 3.5 m.u. apart on the same chromosome. What is the recombination frequency between H and K
Answer:
3.5 percent (3.5%)
Explanation:
In genetics, crossing over or 'recombination' refers to the exchange of genetic material between non-sister chromatids of homologous chromosomes during meiosis I. The map units (m.u.), also known as centimorgans, represent a measure of genetic linkage between genes/loci located on the same chromosome. One map unit (1 m.u.) is equal to a 1 percent chance that two gene/loci (in this case, genes H and K) will be separated during meiosis by recombination. In the example above, it means that among their progeny, 3.5 percent (3.5%) will be recombinant for the two genes (H and K), and 96.5 percent (96.5%) will have the parental combination of these genes.

Describe at least three large - scale detrimental consequences of rising temperatures
Answer:
En primer lugar hay que decir que en contra de lo que puedan pensar muchas personas, el aumento de las temperaturas es una realidad. De hecho, no hay más que ver algunos datos comparativos para darse cuenta, por ejemplo, de que la temperatura de los polos ha aumentado considerablemente en el último siglo.
En primer lugar y por encima de todo tenemos que tener muy claro que el hábitat está cambiando de una manera abismal por lo que la vida del ser humano en La Tierra cada vez es más complicada. Si a esto le unimos el hecho de que nosotros no somos el único ser vivo cuya vida se complica, podemos concluir que muchas especies no serán capaces de adaptarse a estos cambios por lo que morirán. Un cambio que se puede llevar consigo gran parte de las cosechas que existen a día de hoy.
Una serie de consecuencias que lejos de ser catastróficas son más que plausibles. Es cierto que del mismo modo que esta situación se puede dar, no es menos cierto que todavía hay opciones de revertir la situación. La pregunta, sin embargo, es saber si el ser humano está dispuesto a ello.

What do coral reefs and estuaries have in common?
Answer: hewo, there! your answer is below
stuaries are areas of water and shoreline where rivers meet the ocean or another large body of water, such as one of the Great Lakes. Organisms that live in estuaries must be adapted to these dynamic environments, where there are variations in water chemistry including salinity, as well as physical changes like the rise and fall of tides. Despite these challenges, estuaries are also very productive ecosystems. They receive nutrients from both bodies of water and can support a variety of life. Because of their access to food, water, and shipping routes, people often live near estuaries and can impact the health of the ecosystem.
Explanation: Here's some Info Below <3
shallow water, reef-building corals have a symbiotic relationship with photosynthetic algae called zooxanthellae, which live in their tissues. The coral provides a protected environment and the compounds zooxanthellae need for photosynthesis. In return, the algae produce carbohydrates that the coral uses for food, as well as oxygen. The algae also help the coral remove waste. Since both partners benefit from association, this type of symbiosis is called mutualism.
Deep-sea corals live in much deeper or colder oceanic waters and lack zooxanthellae. Unlike their shallow water relatives, which rely heavily on photosynthesis to produce food, deep sea corals take in plankton and organic matter for much of their energy needs.
Every organism has a unique ecosystem in which it lives. This ecosystem is its natural habitat. This is where the basic needs of the organism to survive are met: food, water, shelter and a place to breed. All organisms need to adapt to their habitat to be able to survive. Animals and plants with adaptations that make them better suited for the environment will survive and reproduce better than those less suited for the environment. What adaptations are beneficial in the taiga or boreal ecosystem, marked B on the map? Select ALL that apply

I did the science moon phases for this! I would explain if it showed the graph and everything.
Good luck with it!
The Moon's orbit, which completes one full spin in 27 days, 7 hours, and 43 minutes, is the source of this motion. It compels the Moon to move 12–13 degrees east every day. February 25, March 27, April 25, May 24 Thus option C is correct.
What is Full Moons?When the Moon fills the sky in a perfect circle, it is said to be full.
We can only view the portions of the Moon that are illuminated by other objects because the Moon doesn't create any visible light on its own.
This change causes Moonrise to occur every day around 50 minutes later and necessitates a slightly longer Earth rotation to bring the Moon into view.
Technically, the Moon's “fullness” lasts only a brief period of time.
Therefore, the Moon can appear to be full to the unaided eye for as long as three days.
