In the Arthropods experiment the control is not needed since c. the treatments can then be compared to each one rather than that of a control. Hope this is the right answer and would be of big help to your assignment.
The correct answer is C. Students communicate results in laboratory reports, and professional scientists communicate results in scientific journals.
Explanation:
Both students and scientists can carry out scientific research that involves studying a phenomenon by using the scientific method and scientific instruments. However, professional scientists and students differ in their level of knowledge and expertise in science. This makes scientific research made by scientists to have some differences in comparison to scientific research by students.
One of these differences is the way results are communicated. Indeed, students develop simple scientific research and the results are communicated in laboratory reports at school, colleges, etc. On the other hand, professional scientists develop complex research. Due to this, results are communicated in academic texts with strict criteria and that can be seen by other scientists, these are known as scientific journals.
<h2>Answer:</h2>
To treat the discharge of untreated waste from a type i or type ii marine sanitation device the following steps should be taken into account;
The “Y” valve must be secured to prevent accidental illegal discharge. This can be done by placing a lock or non-reusable seal on the “Y” valve or by taking the handle off the “Y” valve. Only treated sewage from an approved MSD may be discharged directly overboard.
Autotrophs are able to make their own food and sustain themselves without consuming other organic molecules.
