Answer:
C. Flagella
Explanation:
Axial filaments are the locomotory organs. They are found in the spirochetes such as Borrelia. Each axial filament is made up of fibrils which are similar to the flagella. These are originated from the periplasmic space of the cell. Periplasmic space is the space between the inner and outer membrane of a cell. It also helps in rotating the cell body. Axial filaments are made up o many endoflagella. It is a special type of filament that arises from endoflagella. Axial filaments help the cell contraction in forward, and backward direction like a screw.

quizlet said so if this is wrong then im getting it wrong too
When we mix sand and water, no reaction takes place. The sand simply settles down at the bottom of the water container. This is because sand is heavier than water and hence cannot float in water. ... In comparison, if we mix something like salt or sugar in water, they will react and make the water salty or sweet.
Answer: Angiosperms are the plants which produce flowers for sexual reproduction.
Explanation:
In the angiosperm life cycle the following events occur:
1. Seed germination: Under suitable condition inside the soil obtain water, oxygen and minerals the seed germinates and from the two precursors plumule from where the stem emerge and radicle from where the root emerges.
2. Mature plant with flower: The plant gets matured with the develop of root and shoot and from the shoot the bud originates which produces the flower.
3. Pollination: During the process of pollination a mature pollen grain is transferred towards the female reproductive structure typically the stigma receives the pollen grain.
3. Fertilization of pollen with egg in ovary: The pollen is the male gametophyte which develops in the anthers which are the male reproductive structure of the flower and the egg or ovule is the female gamete which develops inside the ovary or female gametophyte. The fusion of male gametes provided by the pollen grain with that of the ovule is called as fertilization.
4. Formation of fruit with seed: After the fertilization process the ovules develop into seed and the ovary into fruit.
5. Seed dispersal: The fruit gets detached from the plant and it may get rotten and dried the dried seeds disperse and may germinate in favorable conditions.
Answer:
A cladogram is used by a scientist studying phylogenetic systematics to visualize the groups of organisms being compared, how they are related, and their most common ancestors. Cladograms represent hypotheses about the evolution of organisms and are subject to revision when theories are disproved and additional data become available.
