Answer:
Explanation:
Crop rotation
Rotation of crop is important to help conserve nutrients that are available in the soil and prevent total use up of the nutrients. The same type of plants all year round on the same soil keeps on draining the land of the same nutrients needed for their growth. Rotation of different can help maintain soil nutrients level as some crop fixes nutrients in the soil.
Natural mulching
The use of cover cops as mulch helps protect the soil and allows for retention of nutrients. When cover crops are harvested the leaves can be turned back into soil to release nutrients that are stored up in the plant part.
Composting is the process of decomposing organic matter this could include animal waste such as dung,leaves both green and dead, kitchen. This waste are stored up, little water is added to moist and then allow to decompose it can be mixed together after few days to aerate after. After decomposing to form compost it can be added to the soil. It is usually rich in nutrients.
Answer:
it would be Fragilariopsis curta because it is part of the diatom subspecies of algae and has a hard bone like silica shell making it more like a crustacean than a true algae
Answer: C). Extraction
Explanation:
Minerals are the inorganic susbtances obtain from the under surface of the earth crust. They are collectively found in the geosphere of earth.
The mineral formation is a long geomorphic process it does not involve any biological activity. After mineral formation mineral extraction is the next step in the resource cycle.
The extraction process involves mining techniques.
Answer: The results will tell us about the correctness of hypothesis.
<u>Explanation:</u>
The Hypothesis is that explanation which is used as a starting of any investigation. The Hypothesis can or cannot be correct. We can test the hypothesis with scientific research.
Now a student can make conclusions about the hypothesis based on the results obtained. If results are the same as the hypothesis it means that our proposed explanation i.e hypothesis was correct but if the result differs than it means the hypothesis was not correct.
There is no prescribed length of time it takes to photographically document a crime scene. The amount of time spent depends on the size and complication in the crime scene, how much there is to document and environmental factors like weather or danger to the investigative team. It can consist of thousands of photographs and hours of work.
Crime scene photography should not just focus on the obvious. The purpose of crime scene photography is to document what is there and where it is in relationship to the scene, whether it is obviously connected to the crime or not. For example, a photographer in Florida shot the inside of every cabinet and the refrigerator at a homicide scene in a home, just as a matter of procedure. It was later discovered that the victim had a receipt for a six-pack of beer, matching the beer shown in the photograph of the refrigerator. Relatives noted that the victim did not drink beer. Further investigation led the team to the convenience store where the beer was purchased and the surveillance tape showed the victim with an unknown person purchasing the beer. It turns out that the victim had picked up a hitchhiker, purchased beer for that person and come back to the house. The photograph of the refrigerator contents had created the link enabling the investigators to find the suspect.
