Explanation:
The plasma that filters through the blood capillaries into the interstitial fluid does not contain red blood cells or platelets as they are too large to pass through but can contain some white blood cells to help the immune system.
Answer:
<em>Magnetic Field</em>
Explanation:
The outer core of the Earth possesses molten iron. This core gives rise to convectional currents. The movement of the convectional currents gives rise to the electric currents which make up the magnetic field of the Earth. The magnetic field of the Earth is also known as the Earth's magnetosphere. This is the area which comprises of the magnetic field of the Earth caused due to the movement of ions inside the core of the Earth.
Answer:
The pattern of growth in which the child is able to control the head and neck before the arms and legs is known as Cephalocaudal Growth.
Explanation:
Cephalocaudal Growth.
This type of growth pattern happens with the humans when they are infants, where fastest growth takes place at the upper part of the body which includes, head. Then the growth started with the gradually lower parts like neck, shoulder etc.
1. Griffith in his experiment used two related strains of bacteria (Streptococcus pneumonia), known as R and S and mice, trying to develop a vaccine against pneumonia. R strain-formed nonvirulent, rough-edged colonies
S strain- rounded and smooth colonies, with sugar protection coat, virulent
Mice that were injected with S strain developed pneumonia and died.
But, when mice were injected with heat-killed S strain it did not cause disease in mice.
The next part of experiment is the injection of combined harmless R bacteria with harmless heat-killed S bacteria. The result was that the mouse developed pnenumonia and in blood sample from the dead mouse, living S bacteria were found.
2. From his experiment, Griffith concluded that injected together, R strain and S strain bacteria most likely “communicate”. The R-strain bacteria took "transforming principle" (we know today that this is genetic material DNA) from the heat-killed S bacteria which allowed them to "transform" into virulent bacteria.
Number 13. is called the Ilium of the small intestine..
