Answer:
List three ways of reducing friction. 1.Polishing the rough surface. 2.Providing all bearings or wheels between the moving parts of a machine or vehicles reduce friction and 3.allow smooth movement as rolling friction is less than sliding friction.
The process of development of adults from the unfertilized egg is known as parthenogenesis. Parthenogenesis occurs in insects such as bees, wasps and bumble bees. Normally, males are produced in these insects. The individuals develop from unfertilized eggs and contain the single (haploid) set of chromosome.
The function of those tiny root hair cells is to speed up osmosis.
They absorb water and go from the roots to the rest of the plant.
Answer:
As amoeba is a unicellular organism all the physiological processes are performed by the single cell.
Explanation:
The food is captured by the pseudopodia and after entering into the body it forms food vacuole. Then the food is broken down by enzymatic activities within the food vacuole and the simplified food absorbed by the cytoplasm.
The remaining undigested food is expelled by the plasma membrane. This is done by rupture of the cell membrane and the waste products diffused out of the plasma.
Most of the time the food captured by amoeba is absorbed more and less waste is formed.
Amoeba reproduces the process of binary fission. It is a type of asexual reproduction where the body is divided into 2, 4, 8.... then 16 and so on.. many cells. These small amoeboid cells grow and become new organisms.
As it is a single-cell organism, nutrition, assimilation, excretion, the reproduction process occurs at a fast rate.
