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:

hypertonic is when blood cells shrivel under hot temperatures

isotonic is equilibrium between concentration of blood and salt

hypotonic is less concentration on outside compared to inside

Answer:

When a cell is placed in a hypotonic environment, water will enter the cell, and the cell will swell. ... If placed in a hypotonic solution, a red blood cell will bloat up and may explode, while in a hypertonic solution, it will shrivel—making the cytoplasm dense and its contents concentrated—and may die.

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.

Therefore, photosynthesis and cellular respiration provides an organism with usable energy.

Answer:

It goes in order like this:

1. Water absorbs solar radiation during the day.

2. Daytime temperatures remain moderate.

3. At night, water releases heat.

4. Heat released by water prevents Earth from freezing at night.

I hope this helps! :)

The correct order to explain how water regulates the planet’s temperature is as follows:

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.

Answer:

In some reactions, a single-reactant substrate is broken down into multiple products. In others, two substrates may come together to create one larger molecule

Explanation:

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.

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.

Answer:

The parts include a plasma membrane, cytoplasm, ribosomes, and DNA.

Explanation:

The structures found in every living cell are:

Cells are the smallest anatomical unit of organisms that perform all the characteristic functions of living beings, their structures are functionally related in order to keep the cell alive and reproduce it.

The outer limit of the cell is the plasma membrane.

It has two basic functions:.  

• Receive signals from the environment or from other neighboring cells.  

• Be a selective barrier of substances, allowing to concentrate those that the cell needs for its metabolism and to eliminate its waste.

The cytoplasm is the compartment found inside the plasma membrane, which consists of an aqueous substance in which various molecules and macromolecular complexes are immersed, as well as different types of organelles.

All living cell store in the form of DNA, deoxyribonucleic acid, the information necessary to control their activities (reproduction, metabolism), and to establish their own structure. DNA is a polymer formed by a linear sequence of monomers, called nucleotides.

Therefore, we can conclude that the main structures found in every living cell are the plasma membrane, and the compartment that it encloses, called cytoplasm, which contains the hereditary material (DNA), where cellular activities are governed.

Answer:

arrive at a conclusion

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:

In 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.
