Hanson is designing an experiment to test the porosity of a soil sample. His experiment involves the following:
Place the soil sample in a water-tight container.
Slowly pour water into the container.
Measure the volume of water that the soil absorbs.
Which of the following would improve Hanson's experiment?
A.
if he measured the volume of the soil beforehand
B.
if he measured the mass of the soil beforehand
C.
if he measured the porosity of the water beforehand
D.
if he measured the mass of the water beforehand
Answer:
A
Explanation:
If he measured the volume of the soil beforehand.
If Hanson measured the mass of the soil beforehand and then Slowly pour water into the container and measure the volume of water that the soil absorbs. This would improve Hanson's Soil porosity experiment.
What is porosity of soil?The percentage of total soil volume taken up by pore space is known as soil porosity.The porosity of a soil is essential for a variety of reasons. The fact that soil pores contain the groundwater that many of us drink is one of the main reasons. The oxygen contained within these pore spaces is another significant feature of soil porosity. Because all plants require oxygen to breathe, a well-aerated soil is essential for agricultural production.Soil particle texture, soil structure, soil compaction, and the amount of organic material in the soil all influence its porosity. A fine-textured soil can hold more water than a coarse-textured soil.How will measuring the mass of soil beforehand will improve Hanson's experiment?when the mass of soil is measured prior to the experiment, it will contain a certain mass (M1) which will be lesser than the one gained after the experiment.After water is poured over the soil, the mass (M2) of the soil will increase due to absorption of the volume of water.the total water absorbed can be calculated by subtracting M2 from M1 which will give the total volume of water absorbed by the soil.other options are incorrect:
if he measured the volume of the soil beforehand soil is measured in mass and liquids like water have a volumeif he measured the porosity of the water beforehand, water does not have porosityif he measured the mass of the water beforehand, water does not have mass it has volume. measuring volume of water before experiment is of no use.learn more about Soil porosity here:

Unit 2 Short Answer Question (Do NOT leave blank): Use the following words to fill in the blanks: transcription, dairy products, enzymes, proteins, repressor, rna polymerase, lactose intolerant, lactase, operator, ecoli, transcribe, bases, repressor, operator.
An example of prokaryotic gene expression is the lac operon. When a person is 1)____________, they do not produce the enzyme 2)___________, which aids in the digestion of lactose, the sugar found in 3)______________. If a person who is lactose intolerant eats or drinks a dairy product, lactose travels down the digestive tract into the large intestine, where the genes in the bacteria, 4)__________ , are turned on to create the 5)_______ / 6)________ needed to digest the lactose. In E.Coli, when lactose is present, it acts as an inducer and binds to the 7)____________ protein, keeping it from attaching to the 8)___________. 9)_____________ then is able to attach to and 10)___________ the E.Coli gene by matching up the 11)______. When lactose is NOT present, the 12)____________ protein binds to the 13___________ and transcription is blocked. This is an example of gene expression (production of proteins) being controlled at 14)_____________.
Answer:
1. lactose intolerant
2. lactase
3. dairy products
4. E.coli
5. enzymes
6. proteins
7. repressor
8. operator
9. RNA polymerase
10. transcribe
11. bases
12. repressor
13. operator
14. transcription
Explanation:
Lac operon is good example of prokaryotic gene regulation. The lactose operon or lac operon is a type of operon which is use to transport and metabolize the lactose in E.coli and other bacteria. The lac operon is made up of three important components including promoter, an operator, and three genes that encode the enzymes required for lactose digestion.
A person who is lactose intolerant is unable to produce the enzyme lactase, which helps in the digestion of sugar generally present in dairy products. The lac operon is regulated by lactose in the environment.
So, when lactose intolerant people consume dairy products, the gens in bacteria E.coli present in the large intestine, turn on to produce enzyme or proteins required to digest the lactose.
When lactose is present, lac operon in E.coli, acts as an inducer and binds to the repressor protein which prevent it binding to the operator. RNA polymerase the binds to the promoter and transcribe the E.Coli gene by matching the base pair or bases.
When lactose is absent, repressor protein is allow to bind to the operator and inhibit the transcription process in E.Coli. The whole process is regulated during transcription in prokaryotes that involves lac operon.
Hence, the correct words for the blanks are as following:
1. lactose intolerant
2. lactase
3. dairy products
4. E.coli
5. enzymes
6. proteins
7. repressor
8. operator
9. RNA polymerase
10. transcribe
11. bases
12. repressor
13. operator
14. transcription

Explain why a dead tree would still be a biotic factor, even though it is no longer alive.
Answer:
I think it's because it will decay and be soil and soil is biotic factor
A dead tree would still be a biotic factor, even though it is no longer alive because biotic factors include living organisms and the remains of the living organisms.
What are biotic factors?Biotic factors are those factors that are living and growing and reproducing. The living organism that were once lived are also comes sunder biotic factors.
A dead tree mean a dried tree that still has wood and dry leave. The wood will decompose or will use in burning purpose. The dead tree will still consider as a biotic factor because it was once alive.
Thus, Even if it is no longer alive, a dead tree would still count as a biotic factor because biotic factors comprise both living species and their remains.

How do the geography and geographical features of your area affect the temperature?
Answer:
An area's latitude on the surface of the Earth affects the weather because it changes the intensity of the sun's light that the area receives. Things like mountains affect the weather by directing air currents, which can send storms to you, or keep them away. If you live in a place with lots of vegetation, it will be more humid, and warmer, because the plants retain the heat.

Doctors often count the amount of neutrophils in a person's blood to see if he or she has a certain illness. Why would this be a useful test?
Answer:
Because they will increase or decrease in specific diseases which, along with other cell counts, would help narrow down the illness.
Explanation:
Lymphocytes one of the subtypes of immune cells present mainly in the lymph of the lymphatic system. They are composed of 3 types of cells
T-Cells
B-Cells
Natural-Killer (NK) Cells
T-Cells and B-Cells function as detection cells. Where they recognize & mark "non-self cells" or "infected self cells" as potential threat to the body and initiates or signals for their immediate elimination.
NK cells on the other hand, will recognize & eliminate "non-self cells" or "infected self cells" directly.
These cells will mostly respond to viral infections or tumor cells. Thus, their blood levels will increase mostly in these situations.
This means that if the patient is suffering from a fever or a sore throat, then the doctor can conclude whether this infection is caused by a viral or bacterial infection depending on how high Lymphocytes increases in the CBC test.
However, it should be noted that it is not used as a "sole" test but one of the tests to help narrow-down and pin-point the illness.

Hope this helps..
Answer:
C) Cladograms are detail-oriented and do not provide a useful understanding of evolutionary relationships.
Explanation:
Cladograms are not necessarily helpful because sometimes organisms with similar characteristics can emerge based on environmental factors and not necessarily from the same ancestors. This is the idea of convergent evolution where two species can have same characteristics but are not related at all and since, cladograms are based on depicting evolutionary relationship based on similar characteristics, it fails to take into account the effects of convergent evolution where same characteristics does not necessarily mean same ancestor.
Cladogram is not an evolutionary tree so it does not show an evolutionary relationship or kinship among ancestors and descendants

What is an experiment?Replicability and validity are important concepts in experimental research. Replicability refers to the ability to repeat an experiment using the same methods and obtain similar results. Validity refers to the extent to which an experiment measures what it is intended to measure. To ensure that an experiment is replicable and valid, researchers must take several steps. One important step is to include a control group in the experiment. A control group is a group of participants that does not receive any treatment or intervention.
