7. Observations and inferences are
important in science. How would you
explain the difference between the
two words?
Answers
Hey there! I'm happy to help!
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.

a. Its chemical properties change.
b. Its physical properties change.
c. The energy of its particles remains the same. hape
d. two of the above
Answers
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:
d.
Explanation:
Its chemical and physical properties changes as a result of a change in temperature (increase or decrease in temperature).

Jorge is studying a pond ecosystem in his neighborhood. The pond is home to a variety of plant and animal species, as well as a stop for birds that migrate through the region.
One summer, heavy rains wash an unusual amount of fertilizer into the pond. Jorge observes the algae population growing rapidly, and quickly algae cover the pond's surface. Several weeks later, many fish and other animals die in the pond. However, within two years, the algae population has returned to its previous size, as have the populations of all the ecosystem members.
Jorge's observations provide the strongest evidence for which of the following conclusions about the pond?
A. The pond ecosystem has very high biodiversity that protects it from invasive species.
B. The pond ecosystem is resilient to changes in many abiotic and biotic factors.
C. The pond ecosystem can withstand only certain levels of algal growth.
D. The pond ecosystem may change over time, but its species will continue living there indefinitely.
Answers
Answer:
I think that the answer is C.
Explanation:
If the levels of algae were too high then it would be the reason as to why the fish died. When the algae went back to normal,the fish were able to live there again.

Answer:
C.The pond ecosystem can withstand only certain levels of algal growth.

do you think your heart plays the biggest role in the process of getting your blood become rich in oxygen and transporting materials gases and other molecules to and from the different parts of the body?
WHY DO YOU THINK SO?
Answers
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.

Describe the roles of the soil organisms in the carbon cycle
Answers
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.
What is the role of soil organisms in the Carbon Cycle?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.

Describe the effect of increased carbon dioxide concentration on blood pH
Answers
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.
What is the normal blood pH?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.

Which of the following will NOT denature
a protein?
A. pH
B. temperature
C. too many enzymes
D. salt content
Answers
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.
Enzymes are a type of protein so they will not get denatured in presence of one another.Enzymes are proteins that speed up any biochemical reaction in the body.What is denaturation of protein?It is a process of modifying the molecular structure of a protein.It involve breakage of many of the weak bonds within the protein molecule that are responsible for the structure of protein and its order.It can happen due to high temperature, pH, salt concentration and mechanical concentration.To know more about denaturation of protein here
