Answer:
A mass movement can either be slow or rapid. The slow downward movement of materials in a slope is called creep. This happens when the soil loosens up because of water and burrowing animals. In contrast to this, the rapid movement of large materials in a slope is called landslide.
Answer:
a. disruption of mitotic spindle formation.
Explanation:
Vinblastine is a chemotherapeutic drug which is used to restrict cancer cell proliferation. During metaphase, it binds to microtubular proteins which play a very important role in mitotic spindle formation. If spindles will not form then during anaphase, the sister chromatids will not separate and mitosis will not take place. This is how hyper-proliferative cancerous cells are controlled from dividing and cancer is treated using this drug.
Answer:
The chemical structure of a saturated fatty acid exhibits each carbon bonding to the adjacent carbon with single bonds. Each carbon is also bonded to two hydrogen atoms. The linear nature of saturated fatty acids allows for tightly packed formations, causing them to be solid at room temperature
Renal medulla
The renal medulla contains the renal pyramids, where urine formation takes place. Urine passes from the renal pyramids into the renal pelvis. This funnel-shaped structure occupies the central cavity of each kidney and then narrows as it extends out to join the ureter.
