Answer:C. Point, nonpoint
Explanation:
Point source of water pollution originate from a single source and the source of origin can be determined. Industrial and sewage drainage systems are the examples of point source pollutants. The source of pollutant is easy to detect and monitor.
Non-point source of water pollution the source of pollution remains undetermined. The pollutants may enter in water body through multiple sources. Hence, it is difficult to track back the source of single pollutant. Thus non-point source pollution cannot be clean and monitored.
The teacher would be well advised to help students encode information about the cell using both visual and verbal forms. This is because, multiple forms of encoding increases the probability of easy retrieval. Encoding in this case involves converting the names of the cell organelles to forms that can easily be remembered.
Answer: Annelida
Leeches are soft bodied segmented parasitic worms. They belong to the phylum Annelida. They are hermaphrodites which means they exhibit sex organs of both male and female.
The characteristics which are found in leeches which group them into Annelida are:
1. The body of the leeches are bilaterally symmetrical like other Annelids. The body organs are also segmented.
2. They have a closed circulatory system in which the heart pumps the blood to all the parts of the body.
3. Leeches either exhibit a protusible pharynx or proboscis which allows them to suck the blood of the host such features are also common in other Annelids.
Answer:
The correct answer is "Catalase".
Explanation:
Catalase is an enzyme that is found in practically all living beings for their important function of catalyzing the reaction of decomposition of hydrogen peroxide to water and oxygen. Catalase is primarily found in organelles involved in respiration and photorespiration, such as mitochondrias and peroxisomes. If catalases are found in rough ER microsomes it would indicate that rough ER has been contaminated with another organelle, such as mitochondrias and peroxisomes.
