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>

There'll be a decrease in health risks and problems, for one.
Answer:
1000, 2000 and 3000.
Explanation:
The example given in the question is of a DNA with 4000 base pairs and it is being cut at 1000 pairs, 1500 pairs and 3000 pairs. So the lenghts of the segments that are cut from the original spiral are 1000, 500, 1500 and 1000 respectively. And the information that only the linear fragments are being produced is given to us in the question so the sizes of DNA expected would be 2000, 1000, 3000 and 2000 again respectively.
I hope this answer helps.
Answer:
E. bind to troponin which moves the tropomyosin
Explanation:
calcium ions bind to troponin, causing conformational changes in troponin that allow tropomyosin to move away from the myosin binding sites on actin. Once the tropomyosin is removed, a cross-bridge can form between actin and myosin, triggering contraction
Incomplete dominance is when the phenotypes of the two parents blend together to create a new phenotype for their offspring.
Co-dominance is a relationship between two versions of a gene.
Therefore, In complete dominance, only one allele in the genotype is seen in the phenotype. In codominance, both alleles in the genotype are seen in the phenotype. In incomplete dominance, a mixture of the alleles in the genotype is seen in the phenotype.
