Mkey [24]

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.

The gene for tallness (T) in a pea plant is dominant over the gene for shortness (t).
astra-53 [7]

Answer:

C. 75%

Explanation:

From a heterozygous cross (Tt x Tt) the produced offspring would consist of:

  • 25% TT -it would be tall-.
  • 50% Tt -it would be tall as the gene T is dominant-.
  • 25% tt -it would not be tall-.

Thus the produced offspring that would be tall is (50% + 25%) 75%. The answer is option C.
