Ancestors can be described as the persons from which a particular human being originated. In a broader perspective, it is referred to family history of a person. Scientists believe that all organisms on Earth originated from a common ancestor which were the prokaryotes. The prokaryotes with time gave rise to the eukaryotes. Common descent is the phenomenon in which organisms having common ancestors are referred.
Which option identifies the best technique to employ in the following scenario?
An elementary school in New York City wants to teach students the benefit of
sustainable farming.
urban greenhouse
precision agriculture
aqua-farming
vertical farming
Vertical farming is the best technique for teaching the benefit of sustainable farming in an urban New York City elementary school due to its space efficiency and the hands-on learning experiences it can provide to students. So the correct option is the fifth option.
Explanation:The best technique to employ in teaching elementary school students in New York City the benefit of sustainable farming could be vertical farming. This method is well-suited to urban environments where space is limited. Vertical farming involves stacking layers of plants on top of each other and growing them indoors, often using hydroponic or aeroponic systems. This type of farming conserves space and resources, reduces transportation costs and emissions by growing food close to where it will be consumed, and can provide fresh local produce year-round.
While options like urban greenhouses, precision agriculture, and aqua farming are also methods of sustainable farming, vertical farming is often more practical and visible for an urban school setting. It also serves as an excellent educational tool to demonstrate sustainable practices and innovative agricultural technology to students.
Moreover, this technique doesn't require large tracts of land and can be implemented on a small scale within the school itself, offering students hands-on learning experiences.

How many distinct stages must occur between the point when light first encounters chlorophyll and the point at which
can be used as energy by the plant?
Two
three
five
eight
Explanation:
Three.
Photosynthesis produces glucose and O2 from inorganic CO2, light energy and water. This occurs in distinct steps: 1) light fixation, 2) electron transport and NADPH production 3) ATP generation, then 4) carbon fixation and carbohydrate production.
6CO2 + 6H20 + (energy) → C6H12O6 + 6O2
Further Explanation:
Photosynthesis is a chemical process, essential to plant and other primary producers producing energy. As oxygen is emitted, energy in the form of glucose molecules is created from light, water, and carbon dioxide. It happens in several complicated stages, photosynthesis is a speed-limited process, depending on several factors including concentration of carbon dioxide, ambient temperature and light intensity; energy is extracted from photons, i.e. light particles, and water is used as a reduction agent. It occurs in the thykaloids, where pigment molecules live like chlorophyll.
Photosynthesis occurs in several complex steps and is a reaction of a small duration, depending on several fa factors including carbon dioxide concentration, ambient temperature and light intensity; the energy is retrieved from photons, I.e. particles of light, and water is used as a reducing agent. Water supplies the chlorophyll in plant cell with replacement electrons for the ones removed from photosystem II.
Additionally,
Water (H2O) divided into H+ and OH-by light during photolysis serves as a source of oxygen along with acting as a reduction agent; it reduces the NADP molecule to NADPH by supplying H+ ions and generates molecules of the energy storage molecule ATP through an electron transport chain. This happens in the thykaloids, where pigment molecules reside like chlorophyll. Later, NADP and NADPH are used in dark reactions during the Calvin cycle, where monosaccharides or sugars such as glucose are produced after several molecules have been modified. These store energy in their bonds which in the mitochondria can be released in respiration.Learn more about photosynthesis at brainly.com/question/4216541

2. Explain how a breeder might produce a new breed of dog
with long ears and a snub nose and how this new breed is
evidence of evolution
Answer: The breeder should choose the two dogs with those distinctive figures, thus concluding a mix of both breeds. This is evidence of evolution because a new breed will be brought up.
Explanation: Example, breeding a shih tzu and a poodle concludes to a new breed which is a p tzu. Sounds funny, but true. Evolving the dogs world even further.
Final answer:
A breeder might produce a new dog breed with long ears and a snub nose through artificial selection, repeatedly breeding dogs with these traits. This process mirrors natural selection and provides evidence of evolution, as it shows how selective pressures can lead to the development of new traits within a population.
Explanation:
A breeder aiming to produce a new breed of dog with long ears and a snub nose would use a process known as artificial selection. This involves selecting dogs that exhibit long ears and a short snout and breeding them together. Over multiple generations, by consistently choosing and mating individuals with desired traits, these characteristics would become more pronounced within the breed due to the inheritance of these traits. This type of selective breeding is what led to the variety of dog breeds we see today, from the tiny Chihuahua to the large Great Dane, all derived from a common ancestor related to wolves.
The production of a new breed through selective breeding is evidence of evolution because it demonstrates how selective pressures, whether natural or artificial, can lead to the development of new traits within a population. What starts as slight variations within a gene pool can be magnified over time into significant differences, mirroring the process of evolution in nature, albeit at a much faster and directed pace due to human intervention.
The famous Silver Fox Experiment conducted by Dmitri Belyaev and Ludmilla Tutt showed that selecting for behavioral traits such as docility in wild foxes not only resulted in tamer foxes but also produced physical changes such as shorter snouts and different coat patterns. This experiment provided strong evidence for how selection can lead to changes in morphology as well as behavior, further supporting the concept of evolution through selected traits.
what are the similarities in interphase
Answer AND Explanation:
In spite of its being called the resting phase, many cellular processes take place during this phase. One of the most important of these is chromosomal replication in which each chromosome produces an exact copy of itself. During interphase, the chromosomes are not visible as discrete structures. Instead, they appear as a diffuse tangle of threads called chromatin. Another important event that takes place during interphase is the formation of new cellular organelles, e.g. mitochondria, ribosomes. There is also build up of energy stores which is necessary to drive the mitotic process.

Which criteria do scientists consider when they classify soil? Check all that apply. soil profile climate soil composition bedrock soil horizon
Answer:
Climate and soil composition
Explanation:
Scientists classify soil based on criteria such as soil profile, climate, soil composition, bedrock, and soil horizon, each contributing to defining soil's properties and capabilities.
Explanation:Scientists consider several criteria when they classify soil. These criteria include soil profile, climate, soil composition, bedrock, and soil horizon. The soil profile is composed of distinct layers known as horizons, such as the O, A, B, and C horizons, each with specific characteristics that play different roles in nutrient cycling, water retention, and support for plant life. The climate influences soil formation by affecting weathering patterns, biological activity, and moisture content.
Soil composition is shaped by the type of parent material and influences the soil's physical and chemical traits. Lastly, the soil horizon refers to the individual layers within the soil, like topsoil (A horizon) and subsoil (B horizon), each distinguished by its properties and composition. The underlying bedrock can become the parent material for soil formation affecting the soil through its mineral content and by providing a base for the development of the soil's upper layers.
As carbon dioxide is absorbed by the ocean, the ocean becomes slightly more acidic. Which of the following effect will an increase ocean acidity most likely have on marine organisms?
A: Higher acidity could make it harder for many organisms to build their shells and skeletons.
B: Higher acidity could make ocean levels rise and marine organisms would need to adapt.
C: Higher acidity could make ocean temperatures decrease and marine life populations will increase.
Answer:
A
Explanation:
A drop in blood pH of 0.2-0.3 can cause seizures, comas, and even death. Similarly, a small change in the pH of seawater can have harmful effects on marine life, impacting chemical communication, reproduction, and growth. The building of skeletons in marine creatures is particularly sensitive to acidity
An effect which the increase in the ocean acidity most likely have on marine organisms is the higher acidity could make it harder for many organisms to build their shells and skeletons. Thus, the correct option is A.
What effect foes higher acidity have on marine organisms?As the ocean acidification increases, the amount of available carbonate ions (CO₃²⁻) bonds with excess hydrogen, thus resulting in fewer carbonate ions being available for calcifying organisms to build and maintain their shells, skeletons, and other calcium carbonate structures in the marine organisms.
Ocean acidification is also called as osteoporosis of the sea. Ocean acidification can create the conditions which results into eating away the minerals which are used up by oysters, clams, lobsters, shrimp, coral reefs, and other marine life to build their shells and skeletons for survival.
Therefore, the correct option is A.

what did Renaisance writers write about?
Answer:
The period focused on self-actualization and one's ability to accept what is going on in one's life. The earliest Renaissance literature appeared in Italy in the 14th century; Petrarch, Machiavelli, and Ariosto are notable examples of Italian Renaissance writers.
Explanation:
Final answer:
Renaissance writers created works that reflected the human experience, often incorporating classical themes and promoting harmony and beauty. They explored love, religious faith, and humanistic themes, and the rise of genres such as the Gothic tale marked literary innovation. The writings of Dante, Petrarch, and their contemporaries were key in shaping this transformative period.
Explanation:
Renaissance Writers and Their Subjects
Renaissance writers were deeply influenced by the catastrophes of the 14th century such as the Hundred Years' War, the Black Death, and widespread famines, which paradoxically helped set the stage for the later flourishing of the arts known as the Renaissance. This period is characterized by a revival of interest in the classical knowledge of Greece and Rome, humanist values, and artistic innovation. Dante Alighieri, Petrarch, and Giovanni Boccaccio were among the early figures whose works laid the groundwork for Renaissance thought and literature.
Dante and Petrarch, operating during times of economic recession and social instability, focused on the human experience, integrating elements of classical antiquity with contemporary concerns. Petrarch, particularly, advocated for the use of clear, classical Latin and imitating the style of ancient Roman writers. In the midst of recovery from plague and war, there emerged a wealthier population with a demand for luxury goods, including literature and arts, which stimulated the creation of a new merchant class and patronage for writers and artists. As a result, authors during this time wrote on a range of topics, including human relationships, religious faith, and philosophical inquiry into the nature of love and beauty. Their works often stressed harmony and beauty, two pillars of Renaissance aesthetics.
Emerging out of this context were the Gothic and mystery tales with Edgar Allan Poe and Mary Shelley being notable contributors to this genre. Mannerism later emerged as a reaction against the earlier Renaissance styles, rejecting harmony and ideal proportions for more exaggerated and emotionally expressive forms. The renewed interest in classical Greek philosophy and literature aided Renaissance writers in exploring humanistic themes, with the church providing significant patronage for many works.

Which two structures help produce energy for a plant cell?
nucleus and cytoplasm
mitochondrion and cytoplasm
mitochondrion and chloroplast
cell membrane and chloroplast
The two structures that play crucial roles in energy production for a plant cell are the mitochondrion and chloroplast.
Mitochondria are the powerhouses of the cell, conducting cellular respiration to convert nutrients into adenosine triphosphate (ATP), the cell's primary energy currency.
On the other hand, chloroplasts are responsible for photosynthesis, a process where they capture light energy, convert it into chemical energy, and synthesize glucose.
The nucleus contains genetic information but is not directly involved in energy production.
Cytoplasm is a gel-like substance that houses cellular components, but energy production occurs primarily in the mitochondrion and chloroplast.

a cell is in a solution that contains dissolved oxygen as the cell used oxygen for respiration
Answer:
oxygen in the solution will naturally diffuse into the cell.
Explanation:
Cells require oxygen for cellular respiration to occur. When a cell is places in a solution having oxygen dissolved in it, The concentration of the oxygen outside the cell will be more as compared to the concentration of oxygen inside the cell. As a result, the cell will take up oxygen by the process of diffusion. Diffusion is the movement of particles from a higher concentration to a lower concentration along a concentration gradient.

In the 1700s, Swedish biologist Carl Linnaeus developed a system of classifying organisms in which every organism was given a scientific name that consisted of its species name and genus name. How did Linnaeus's work help future scientists?
Answer:
It allowed scientists to clearly communicate with each other about different organisms.
Explanation:
Carl Linnaeus was a Swedish Botanist who is known for devising the system of classification for organisms and bringing forward the system of binomial nomenclature. Binomial nomenclature can be described as a method by which a scientific name is assigned to every organism based on their genus and species name.
This method is beneficial for scientists so that they can communicate with each other about different organisms. As scientists belonging to different regions had different common names for an organism, binomial nomenclature made possible for scientists to communicate bu using specific scientific names.
