Paramecium is protozoan which is like a bedroom slipper in shape and swims rapidly in a corkscrew fashion by means of an army of cilia that operate in wavelike movements. These tiny creatures are abundant in freshwater ponds, especially in areas that are rich in algae.
Paramecium rescued from a fresh pond in Florida is among the most complex single-celled organisms found in fresh water. The fatty acid side chains in the membrane phospholipids of the Florida Paramecia would generally be longer and would be more saturated compared to those in the membranes of the Canada Paramecia.
Moreover, the species Paramecium bursarial shapes advantageous associations with green growth. The green growth lives in its cytoplasm. Algal photosynthesis gives a nourishment source to Paramecium. Paramecia can be utilized as model creatures to examine. You should know that the paramecium swims by rotating along its longer axis and is constantly in search of food, which is swept into the organism by a series of cilia that line the oral groove and gullet.<span>

B. Nucleus (because the nucleus is to the organelles, like the brain to our organs).
In a mutualistic relationship, both species benefit.
Predation is when a predator eats another organism, in which the predator benefits and the other organism dies.
In parasitism the parasite benefits while the host is harmed.
In competition, neither species benefits because they're too busy fighting over resources.
Commensalism is when only one of the two species benefits but the other is not harmed.
Mitosis consists of four basic phases: prophase, metaphase, anaphase, and telophase. ... These phases occur in strict sequential order, and cytokinesis - the process of dividing the cell contents to make two new cells - starts in anaphase or telophase. Stages of mitosis: prophase, metaphase, anaphase, telophase.
I think the correct answer is C. An investigation is a type of research that involves observation and collection of data but it does not include a control. In an investigation, all data and information that is related to the subject matter are collected it does not think of any factors that may affect the subject.
