Observations are things that can be written down or described. You can observe something with any of your five senses: you can see what color something turns, you can hear the noise something makes, you can taste a cookie with a different amount of an ingredient, you can smell an odor produced by a chemical reaction, and you can feel the texture of different samples.

You can also create observations by using scientific tools. For example, instead of feeling if water is hot or cold, you could use a thermometer. This will give you numerical data which can be put into a table or graphed for further analyzing.

Inferences are created from observation. You cannot make an inference without observation. Observations lead to inferences. Inferences are conclusions or guesses made from the observations. You could infer that sugar makes a cookie taste sweeter after experimenting with no sugar and observing that it tasted bitter. You could infer that more weight allows things to travel further after going down a ramp after measuring the distances different weights travel, graphing it, and observing the data.

Answer:

Explanation:

However, at very high salt concentration, the increased surface tension of water generates a competition between protein and salt ions for hydration. Salts strip off the essential layer of water molecules from the protein surface eventually denaturing the protein

Too many enzymes cannot denature protein.

Carbon cycle is a biogeochemical cycle by which carbon is exchanged among the different components of the Earth.

Carbon cycle along with the Nitrogen cycle and the Water cycle, comprises a sequence of events that are key to make Earth capable of sustaining life.

It describes the movement of carbon as it is recycled and reused throughout the biosphere, as well as long-term processes of carbon sequestration to and release from carbon sinks.

The terrestrial carbon cycle is dominated by the balance between photosynthesis and respiration.

Carbon is transferred from the atmosphere to soil via ‘carbon-fixing’ autotrophic organisms, mainly photosynthesizing plants and also photo- and chemoautotrophic microbes that synthesize atmospheric carbon dioxide (CO2) into organic material.

Fixed carbon is then returned to the atmosphere by a variety of different pathways that account for the respiration of both autotrophic and heterotrophic organisms.

The reverse route includes decomposition of organic material by ‘organic carbon-consuming’ heterotrophic microorganisms that utilize the carbon of either plant, animal or microbial origin as a substrate for metabolism, retaining some carbon in their biomass and releasing the rest as metabolites or as CO2 back to the atmosphere.

Soil Organisms or Microbes are critical in the process of breaking down and transforming dead organic material into forms that can be reused by other organisms and thus the microbial enzyme systems involved are viewed as key ‘engines’ that drive the Earth's biogeochemical cycles.

Soil microbes essentially transfer carbon between environmental compartments to fulfil their fundamental goal: survival through reproduction.

Thus, microbes utilize different organic and inorganic forms of carbon as carbon and energy sources.

Answer:

Matter either loses or absorbs energy when it changes from one state to another. For example, when matter changes from a liquid to a solid, it loses energy. The opposite happens when matter changes from a solid to a liquid. For a solid to change to a liquid, matter must absorb energy from its surroundings.

Answer:

The term would be: Theory

Explanation:

A theory is a supposition or a system of ideas intended to explain something, especially one based on general principles independent of the thing to be explained. It is a well-substantiated explanation of an aspect of the natural world that can incorporate laws, hypotheses and facts.

Explanation:

The Sun and the planets formed together, 4.6 billion years ago, from a cloud of gas and dust called the solar nebula. A shock wave from a nearby supernova explosion probably initiated the collapse of the solar nebula. The Sun formed in the center, and the planets formed in a thin disk orbiting around it. In a similar manner, moons formed orbiting the gas giant planets.

Yes. Absolutely. Without heart, no one can live. It helps in pumping of oxygen rich blood to all body cells and tissues. It also helps in transportation of various materials like potassium, sodium, calcium etc. in our body. The main function is that it helps in excretion of wastes.

Since blood is liquid and heart pumps it, the waste materials like CO2, gets diffused and becomes impure blood. Then it is taken to lungs for purification and again reused.

So, heart actually helps us indirectly in many ways.

Answer:

Explanation:

Answer:

As it combines with water, it forms carbonic acid, making the blood acidic. So CO2 in the bloodstream lowers the blood pH. When CO2 levels become excessive, a condition known as acidosis occurs. This is defined as the pH of the blood becoming less than 7.35

The increase in the carbon dioxide concentration on blood pH leads to the condition known as Acidosis.

The level of normal blood pH in humans significantly ranges from 7.35 to 7.45 on a pH scale. It is considered neutral but experimentally it is slightly basic in nature.

As the concentration of carbon dioxide in the blood increases, the carbon dioxide in the presence of water forms carbonic acid which lowers the blood pH from 7.35.

This reduction in blood pH is known as acidosis. This is caused by the overproduction of acid within the body due to excessive concentration of carbon dioxide in the blood's pH. Acidosis leads to feeling fatigued, lethargic, muscle aches, etc.

Therefore, the concentration of carbon dioxide on blood pH negatively harms the health of an individual.

A. Predictions are guesses you make about the result of a trial. Let's say that you want to test what will happen if you put less eggs into a cookie recipe. You could make a prediction that the cookies will be more crumbly. This is not the term for things that are the same between two groups, so this is incorrect.

B. Controls are a type of variable that isn't influenced in a unique way as part of the experiment. This is to be able to compare the things you change to a thing that hasn't changed. With our cookie example, a control group would just be a cookie recipe with the normal amount of eggs. Then we can compare a normal cookie to one with less eggs. We see that a control is a type of group, and not a specific thing that is similar or different between the groups, so this is incorrect.

D. Variables are things that  can change or vary in your experiment. There are independent variables, which are things that you change, such as the number of eggs in the recipe. Then, you have dependent variables such as color, texture, taste, etc. However, these can change depending on the group because the number of eggs could switch, so this is the wrong term and incorrect.

C. Constants are things that you do not change as part of your experiment. You do not change these variables. In our case, the constants will be all of the other ingredients like the amount of flour, milk, water, sugar, etc. If we have a control group and a group with less eggs, these things will remain constant in both of them. So these things are the same between the two groups, so this answer is correct.

We call the things that are the same between the two groups C. constants.
