Answer:

The correct answer would be - increase in green house effect, increase in temperature and rise in sea level are some major response.

Explanation:

Carbon dioxide concentration soar over 400 ppm which means there are 400 particles of carbon dioxide in a million particles of air. It is on the highest level of all time from the beginning. Carbon dioxide is a green house gas which means it is able to absorb heat and trap it in air which leads to increase in temperature of the earth.

Increase in earth temperature will lead to melting of ice lands which result in rise of sea level and cities will drown in sea. Other effect will be pollution in atmosphere and warmer climate and change in pattern of climate. There are many other direct and indirect response in accumulation of carbon dioxide concentration.

Hello. You have not shown the plazas to be compared, which makes it impossible to answer that question.

However, I can help you by giving you general guidelines on how to make this comparison.

First of all, you should look at the region around the plazas and assess whether the region has luxurious buildings and high purchasing power, or if it has simple and modest houses, common in middle and lower class communities. This analysis says a lot about the public that frequents these plazas, their location and the events that take place there.

If the plaza is located in a region of more luxurious, unusual buildings and close to tourist spots, it is worth mentioning that this is a plaza frequented by people from higher social classes and that frequents more elitist and restricted events. In addition, these plazas tend to be larger than the others.

If the region, however, has more common and less luxurious buildings, it means that this plaza is in a more accessible place, its audience is middle class people and presents more accessible events, but of general interest to the population and less elitist. In addition, these plazas are usually smaller.

Answer:

convergent evolution

Explanation:

This is an example of the term known as convergent evolution. This term refers to the process in which organisms that are not related to one another are still able to independently evolve similar traits. This is all due to both of the species having to adapt to very similar environments thus needing to develop these certain traits in order to survive and pass them on to the next generation in that species line.

Answer:

this represents response to the environment

Answer:Environmental servers build dams to keep water out of areas were animals safe.

Explanation:i just did this one and got it right!

Environmental science helped the trust decide that some dams should be removed dams reduces the complete ecological benefits that can be derived from the free-flowing rivers.

Dams may be defined as a type of barrier that is significantly constructed in order to hold back water and enhance its level that forms a reservoir that is utilized to generate electricity or as a water supply.

Environmental science believed that dams tend to synthesize numerous environmental impacts like alteration in wildlife patterns, destruction of wildlife habituation, interference with the natural flow of water, etc. Dams are also associated with the mechanism of ecological restoration and remarkably interfere with the natural characteristics of water and deteriorate it.

Therefore, environmental science fundamentally supports the trust decide that some dams should be removed.

Explanation:

The nucleus is the small region in the center of the atom containing protons and neutrons. The nucleus has positive charge.

A Proton is positively charged and is found inside the nucleus. The number of protons in each atom is unique to each element. Protons are made of quarks.

Neutrons have no charge and are also inside the nucleus. Neutrons are also made of quarks. The mass of a nuetron is slightly larger than a proton's

I'm not sure if this is enough information but I hope this helps :)

Answer:

I determine if the object is a living thing by checking to see if it responds to the environment

Could determine if it is a living being by checking if it responds to stimuli

Living beings or organisms are all complex structures that are characterized by carrying out activities such as:

Some of the most common classifications of living organisms are:

According to the above, to know if that object is a living organism the best option would be to activate stimuli in it such as vision, touch, smell, hearing, or taste to see if it has any reaction to these stimuli.

For example, you can touch the object and if it moves it shows a response and therefore it is alive.

According to the above, the correct answer is checking if it responds to stimuli

Answer:

D.

Explanation:

The scientific method is a way of doing science that helps answer questions. It also helps to obtain new knowledge.

A way to answer scientific questions is the best description of the scientific process. Hence, option D is correct.

Through testing and experimentation, the scientific method establishes facts in an unbiased manner. Making an observation, formulating a hypothesis, making a prediction, carrying out an experiment, and then evaluating the findings are the fundamental steps.

The dissemination of the findings is the last phase in the scientific approach. After collecting and examining your data, you come to a conclusion regarding your hypothesis. A conclusion summarises the key takeaways from an experiment.

The best description of the scientific process is a way to answer scientific questions. Therefore, the correct option is D.

A round ball is an example of physical change. Thus option a is correct.

Physical changes are changes which affecting the form of chemical substances but not it's chemical composition. Physical change are the processes in which we can separate mixture from compound, but can't usually be used to separate compound into chemical elements or simplest compound.

Physical change takes place when mixture are can't separate by chemical changes then we separate by the help of physical change. In general a physical change is reversible using Physical means.

A physical change involves a change in physical properties. Example- physical properties including melting, freezing, sublimation etc.

Therefore, a round ball is an example of physical change. Thus, option a is correct.

Explanation: It is

Explanation:

When water freezes, water molecules form a crystalline structure maintained by hydrogen bonding. Solid water, or ice, is less dense than liquid water. Ice is less dense than water because the orientation of hydrogen bonds causes molecules to push farther apart, which lowers the density

Solid water, or ice, is less dense than liquid water. Ice is less dense than water because the orientation of hydrogen bonds causes molecules to push farther apart, which lowers the density.

Density is the measure of how much “stuff” is in a given amount of space. For example, a block of the heavier element lead (Pb) will be denser than the softer, lighter element gold (Au). A block of Styrofoam is less dense than a brick. It is defined as mass per unit volume.

Density is an important concept because it allows us to determine what substances will float and what substances will sink when placed in a liquid. Generally, substances float so long as their density is less than the density of the liquid they are placed in.

Density is a measure of how much mass there is in a given volume or amount of space. The density of any substance is calculated by dividing the mass of the matter by the volume of the matter.
