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.
The Answer would most likely be A. The reason for that is because if there is a decrease in hunting the population would grow as long with the surplus of food. If there is no animals hunting them for food then the population would grow. So the first one is only the one that would kill them off.
Answer:
Tendon sheaths protect long tendons as they course over and around synovial joints.
Explanation:
Tendon sheaths are tubes of tissue filled with a lubricating fluid that surround the tendons like a tunnel. The tendon sheath prevents the tendon from fraying or being exposed to excessive friction. The inside of the sheath is lined with synovial fluid. This allows the tendon to slide forward and backward. From this we can say that the tendon sheaths protect the long tendons as they travel through the synovial joints.
Answer: D. Secondary
Explanation:
An ecological disturbance is a circumstance caused by an agent that can be of biological or non-biological origin. The agent is capable of bringing negative changes to an ecosystem. Fire is an example of ecological disturbance. In the given situation, the forest burns down the trees are an example of the direct interaction of fire with the trees; therefore, it is a primary disturbance. Nevertheless, this interaction led to the loss of habitat of animals forced to move to other areas as the fire burned the trees. It is called secondary disturbance.
