C. Fenestrated capillaries have intracellular perforations.
<span>The answer would be: peripheral proteins anchored to the inner surface of their plasma membrane
Red blood cells have ankyrin and spectrin protein in their membrane that responsible for their biconcave shape. The shape itself is beneficial because it allows a larger surface area to accommodate gas exchange. It also allows the red blood cells to be squeezed into the narrow capillary blood vessels.</span>
Answer:
Option D, The work done by each force is negative
Explanation:
When both the forces are negative, then irrespective of which force is large or small, the net force will definitely negative. A negative force indicates reduction in kinetic energy of particle. Since mass is constant , it is the speed which reduces and produces negative work. Reduction in speed is contrasting to the statement give in the question. Hence, option D is not possible.
The herpes virus infects the humans to cause chickenpox disease. The virus during its stage of causing infection, it spreads through the epidermal cells by infecting them. This causes the typical rash on skin that is seen in chickenpox.
