1) In 1668, Francesco Redi wanted to know if meat could spontaneously produce maggots as many people thought at the time. Redi believed that the maggots came from flies that lay eggs on the rotting meat. He placed one piece of meat in a jar and covered it with cloth. He left another piece of meat in a jar uncovered. After two weeks, he inspected the meat and found that the one in the covered jar did not have maggots, but the one open to the air did have maggots. REASONING: If maggots were spontaneously being produced by the meat, then ….

answer; the correct answer is (beta)

tsd is temerature dependent sex determination.

tsd: it is a type of environmental sex determination in which the temperature experienced during embryonic/ larval development (ambient temperature for development) determine the sex of the offspring.

crocodile displays the tsd where the ambient temperature of the developing egg determines the individual's sex. for example in the american alligator's eggs, incubation at 33 ºc produces mostly males, while incubation at 30 ºc produces mostly females. so if the american alligator's egg will get the ambient temperature (33 degree celcius)during embryonic development from egg, the offspring will be male and same for the female sex determination.

straight probes are used primarily for measuring flow as it is approaching the test area. its geometry allows the probe to be mounted so that it is in the direct line of airflow.
