Answer:
The CNS, or central nervous system is comprised of neurons, the cell units that form it. These cells, in turn, are formed by their cell bodies, the dendrites on them and the terminal ends of the axons, which are like the connectors, or roadways, for neurons. When viewed on a microscope, brain tissue, particularly, looks stained with two different colors: grey, or pinkisk, for the grey matter, and whiter for the white matter, which are the axons. This is basically why the two are called grey matter and white matter of the CNS.
So one difference between these two matters is the color they display when viewed. The second is the parts of the neuron that form the two; while the white matter is formed from the neuronal axons, the grey matter is formed by the dendrites, cell bodies and axonal terminals. A third differentiation is that most synaptic activity takes place in the grey matter, while most conduction of information from the cell bodies is performed by the axons.
B) Photosynthesis The Sun is the ultimate source of all energy in the universe. Plants being the main primary producers or autotrophs, use solar energy to make their own food through photosynthesis, thus converting energy into the organic matter that can be consumed by all organisms. They form the basis of almost all food chains from where consumers derive their food.
Using Newton's second law
W=Fd
if F= 20N
d= 5m
W=Fd
=(20)(5)
= 100 J
If Jerry wants to start a small business producing jelly made from marine algae he should select red algae for this purpose. Red algae is a major staple in some Asian and European cuisines.
To collect seeds
Globally, biodiversity is diminishing at an unprecedented rate “at the ecosystem, species, and genetic levels,” Chopra explains. ... Further, groups such as Bioversity International and Global Crop Diversity Trust fund seed banks around the world.
