Radiolaria are unicellular organisms. They have mineral skeletons (tests) that are composed
of silica. The tests are formed through the absorption of silicon
compounds. This skeleton is covered with cytoplasm, which is withdrawn
if the organism is disturbed."

The correct option is B.
The information from the olfactory cells has to reach the cortex before they are transferred to the thalamus. When an odor molecule binds to a receptor, it start an electrical signal, which travel from the sensory neuron to the olfactory bulb. The olfactory bulb relays the signal to the appropriate part of the brain for further processing.
Peripheral tissues receive oxygenated blood via the circulatory system. Delivering oxygen to cells, oxygen diffuses through tissues along a gradient of high to low amounts. Thus, option B is correct.
<h3>What is the movement of oxygen in cell?</h3>
Hemoglobin and oxygen interact chemically inside the red blood cell, where it is carried both by free diffusion and hemoglobin-facilitated diffusion. In blood plasma, oxygen is transferred by free diffusion and convection through cell membranes.
Therefore, The concentration of oxygen will be lower inside the cell compared to outside the cell.

Spindle fibers attach to the sister chromosomes and pull them apart. without them, the sisters would still be attached to each other which means there would be no division.
