A gene is the basic unit of heredity, DNA a self replicating material and chromosome a structure of nucleic acids and protein.
This is the pattern formed in a fluid when heating causes part of the fluid to rise and then cooling causes it to sink again. Within Earth's mantle they circulate heat and drive plate tectonic processes. Within the atmosphere and oceans, they drive winds and weather patterns:Convection Cell
Option(A) is the correct answer.
The alkane with six carbons is called hexane.
<h3>What are the potential hazards of hexane?</h3>
Hexane is used as a special-purpose solvent, a cleaning agent, and to extract edible oils from seeds and vegetables. Humans who are acutely (short-term) inhaled high quantities of hexane have moderate central nervous system (CNS) symptoms such giddiness, nausea, headache, and dizziness. Humans who are exposed to hexane in the air <u>over an extended period of time</u> may develop polyneuropathy, which manifests as numbness in the extremities, muscle weakness, impaired vision, headaches, and tiredness. Rats have also displayed neurotoxic consequences. Hexane's potential to cause cancer in both humans and animals is unknown. Hexane has been categorized by the EPA as Group D, not classifiable as a human carcinogen.

Mass of sulphur:-

Answer:Vrms is 149.7266 m/sec
Explanation:The root means square velocity of a gas can be calculated as follows:
Vrms =

where:
R is the ideal gas constant = 8.3145
T is absolute temperature = -55 + 273 = 118 degrees kelvin
M is the molar mass of the gas = 131.293 grams = 0.131293 kg
Substituting with these givens in the above equation, we would find that the Vrms is 149.7266 m/sec
Hope this helps :)
