Answer:
Paramecium.
Explanation:
Ciliates are group of protozoans organisms that are characterized by special organelles called cilia.
Cilia is used for loccomotion in ciliates and can also be use to move food into the body. The cilia can be use for swimming, crawling, for attachment and sensation. Some ciliates are free living while some are parasitic. They are found in the aquatic habitats both fresh water and ocean.
Answer: Genetic drift may result in the loss of some alleles (including beneficial ones) and the fixation, or rise to 100% frequency, of other alleles.Once it begins, genetic drift will continue until the involved allele is either lost by a population or is the only allele present at a particular gene locus within a population. ... Genetic drift can result in the loss of rare alleles, and can decrease the size of the gene pool.
Explanation:
Answer:
Normal force, gravity and Friction.
Explanation:
The forces acting on the book are normal formal force which act or exerts by the table on the book while on the other hand, gravity is a force that acts in the downward direction. Friction is the force that acts against the motion of the book and is responsible for lowering speed of the book that is sliding on the surface of the table. If the friction is low between the book and table then the book moves easily on the surface.
Answer:
Both electron transport and a proton gradient
Explanation:
The process of oxidative phosphorylation in mitochondria and electron transport chain in photosynthesis undergo chemiosmosis to produce ATP molecules.
Chemiosmosis is a process where the energy utilized by the movement of proton and electrons produces ATP molecules.
Both the processes involve the movement of electrons through electron carriers where the reduced energy is utilized to drive the flow of protons through the plasma membrane. This creates a proton gradient across the plasma membrane which rotates the ATP synthase and converts the ADP molecules into ATP molecules.
Thus, the selected option is correct.
The following which poses as the most logical conclusion about the life cycle of this plant is definitely : The plant is a fern, and the gametophyte is its dominant phase. I am pretty sure you will fing this answer interesting. Regards!
