possible?
Answers
Answer:
The forces the children are exerting on the object balanced one another.
Explanation:
Equal forces acting on an object in opposite directions.
Hope this helps!
Answer:
Sample Response: Forces are either positive or negative vectors, depending on the direction in which the force is acting. The net force is the sum of all of the forces acting on an object. If the children pull on the toy with the same force in opposite directions, the forces will be perfectly balanced and cancel out, leaving a net force of zero.

Explanation:
The analysis of data gathered during a particular experiment is necessary in order to arrive at a conclusion that will address the aim of the experiment.
Without data analysis, valid conclusions about the experiment cannot be made and what the experimenter would have is just raw data that cannot say or answer anything about the experiment.
The data collected from experiments can be analyzed in two ways:
Descriptive data analysis Inferential data analysisIn descriptive data analysis, the collected data is summarized, arranged, or described in such a way that a pattern can be seen at a glance. It includes tables, charts, histograms, etc.
In inferential data analysis, the collected data is treated in such a way that an inference can be arrived at based on the study. This includes testing for a significant difference between means, testing for the goodness of fits, correlations, etc.
Both photosynthesis and cellular respiration are part of the carbon cycle. Which statement best compares these two processes? Both release carbon dioxide as waste. Both provide organisms with usable energy. Both add bacteria to the soil. Both require fixation in order to convert molecules.
Answers
Answer:
Both provide organisms with usable energy.
Explanation:
Both photosynthesis and cellular respiration, a component of the carbon cycle provides an organism with usable energy.
Photosynthesis is the process whereby green plants manufacture their food using carbon dioxide and water using sunlight to produce energy rich glucose and oxygen gas as a by-product.
During cellular respiration is an oxygen driven aerobic process in which organisms breaks down glucose to produce energy rich ATP.
Both processes furnishes an organism with energy in the end. Although, photosynthesis is an energy building process, cellular respiration breaks down materials to liberate energy. This energy is used by both plants and animals for their living activities.Therefore, photosynthesis and cellular respiration provides an organism with usable energy.

Answers
Answer:
They're the Youngest. This information also suggests that Archaeopteryx was once thought to be the oldest known fossil bird.
Explanation:
Hope this helps.
Based on the principle of superposition, we can conclude that the topmost layer is the youngest. Hence, the fossil of birds is the youngest, while Archaeopteryx is younger than dinosaur fossil.
According to the principle of superposition, sedimentary deposits are layered such that, the oldest layer is at the bottom and the youngest is the topmost layer.
Hence, dinosaur fossil are the oldest, followed by Archaeopteryx, then birds.

EXPLAIN Make a claim about the affect urbanization has on
biodiversity. Does urbanization always decrease biodiversity? Use
evidence to support your claim and explain your reasoning. Address
the following questions in your answers
• What are the main factors that lead to biodiversity loss in urban
areas?
• How is the size of a habitat related to its biodiversity and its stability?
• Can an ecosystem in an urban area ever return to its previous state?
Answers
Answer:
Urbanization decreases biodiversity. Land development reduces the size of habitats and affects the availability of resources. Larger habitats have a greater potential for biodiversity. If some of the natural habitat is retained, the impact of urbanization may not be as destructive. Assuming human development and its resulting pollution aren’t too extensive, an abandoned urban area could return to its previous ecosystem.
Explanation:
It is found that urbanization affects the biodiversity and the relationship between them is not linear as with the increase in urbanization the area of forest keeps on decreasing which reduces the natural habitat of many species and lead to their extinction.
What affects biodiversity?
Biodiversity of an area is the total number of living organisms (species) living in a particular area. Most of the biodiversity are found in the forests as these are the natural habitats of many animal species.
The ecological studies conducted on the urbanization and biodiversity have found that the urbanization generally shows a negative impact on the biodiversity levels of an area. The relationship between biodiversity and urbanization is not always a linear relation. As the area of urban citied increases, the area of forest decreases which lead to extinction of many important species.
The forests are the natural habitat of animals, as the natural habitat decreases the biodiversity of an area also decreases which affects the stability of the forest.
An ecosystem in an urban area can be returned to a biodiversity-rich area by introducing species and making the habitat more favorable for them.

you go out to dinner with your best friend. during dinner you consume the following meal: spinach green with sunflower seeds, a Dr. Pepper and a piece of unbuttered french bread. identify the biological molecules that would likely be present and what would they be processed into after
Answers
Answer:
The biology Molecules that will.be present in what she consumed are Carbohydrates from unbuttered bread, vitamins green spinach, Fat and oil or lipids from sunflower seeds, proteins...
The Carbohydrates is processed into glucose, proteins is processed into amino acids, lipids is processed into fatty acids and glycerol.
Explanation:
From the food consumed, The biology Molecules that will.be present in what she consumed are Carbohydrates from unbuttered bread, green spinach contains vitamins like vitamin K, vitamin A, vitamin C, vitamin B12 , minerals like magnesium, iron, Fat and oil or lipids from sunflower seeds, proteins...
The Carbohydrates is processed into glucose after enzymes like salivary amylase acts on it from the chewing and in the stomach which produces glucose which makes it easily absorbable , proteins is processed into amino acids by the activity of hydrochloric acids and protease that processed it into amino acids, lipids is processed into fatty acids and glycerol by the activities of the enzymes lipase.
The minerals and vitamins present are in a way they can be absorbed.
The molecules that will be present in the foods shown above would be sugar, carbohydrates, lipids, fiber, vitamins, calcium, phosphorus, potassium, proteins, and magnesium.
We can arrive at this answer because:
French bread will supply the body with carbohydrates. These carbohydrates will be turned into sugars, mainly glucose.The proteins present in spinach will be transformed into amino acids that will be used in the production of other proteins.The lipids present in sunflower seeds will be transformed into fatty acids, glycerol, and fat.The calcium present in spinach will be absorbed by the bones.Vitamins, phosphorus, and potassium will be broken down and dissolved in the bloodstream.Fiber will be metabolized by the intestine.Based on this, we can say that proper nutrition is important because it promotes essential molecules for the functioning of the body.

The correct order to explain how water regulates the planet’s temperature is as follows:
Water absorbs solar radiation during the day.Daytime temperatures remain moderate.At night, water releases heat.The Heat released by water prevents Earth from freezing at night.What is Solar radiation?Solar radiation may be defined as a type of electromagnetic radiation which is constantly emitted from the sun. Such type of radiation can be captured and transformed into useful forms of energy, such as heat and electricity through the utilization a variety of technologies.
The process of regulating the temperature initiates with the absorption of solar radiation during the daytime, due to this, the temperature of the daytime remains moderate.
This absorbed radiation at night time liberates heat. This liberated heat at night prevents the water to freeze for this specific duration.
Therefore, the correct order to explain how water regulates the planet’s temperature is briefly mentioned above.
