Explanation:
Fossil fuels are nonrenewable resources because the conditions for their formation no longer exist on Earth.
Answer: A. protein like tubules
B. Microtubules
C. Microfilaments
Explanation:
Cytokinesis in the bacteria is facilitated by the presence of these conserved tubulin-like proteins. Due to the fact that their walls are flexible, constriction of these walls is possible aiding in cytokinesis. Unlike in plant that have rigid cell wall, a cell plate is involved in the formation of a new cell wall between the daughter cells. Network of microtubules determines the position of the cell plate which is mostly like a disc in the middle of the two daughter cells. Cleavage furrow occurs in animal cells which is caused by the action of the contractile ring: a ring of actin microfilament.
It is symbiosis, but also called a commensalism relationship because the remora is getting its food and the shark has no benefit.
C) Renal pelvis is the part of the kidney that acts as a funnel to pass the urine that is produced in several nephrons to the ureters.
