Translatory motion can be of two types: rectilinear and curvilinear. If a body moves as a whole such that every part of the body moves through the same distance in a given time, then the body is said to be in translatory motion.
The answer is false.
Euchromatin is a lightly packed form of chromatin not tightly. Euchromatin is usually described as active chromatin, because DNA around the histones (which together form nucleosome) is loosely wrapped enabling transcription. So, euchromatin is rich in genes that are actively transcribed (RNA polymerase, transcription factors and other proteins can bind to DNA).
Under the microscope, euchromatin appears light in color, while heterochromatin (condensed DNA) is dark.
I can’t see question buddy
No population or organism is perfectly adapted. ... The population or individual does not "want" or "try" to evolve, and natural selection cannot try to supply what an organism "needs." Natural selection just selects among whatever variations exist in the population. The result is evolution.
