Answer:

The Miller-Urey experiment was conducted to simulate the conditions on Earth when life arose, and see if a chemical evolution could occur. This experiment was performed without oxygen, because they knew that if oxygen was added, the amino acids would oxidize. In particular, the experiment intended to simulate a volcanic eruption was analyzed.

Thus, particles of water, methane, ammonia and hydrogen were exposed to high temperatures and electric discharges that simulated these eruptions, during a determined period. Later, it was observed that organic compounds had emerged from this exposure, which allowed us to infer one of the hypotheses regarding the origin of life on Earth.

Deficiency of calcium in plants causes ______. A. wilting and poor growth B. chlorosis between veins and wilting C. crinkling of
lesya [120]

Deficiency of calcium in plants causes reduced internode length and crinkled leaves.

Initial signs of calcium Deficiency include localized tissue necrosis that stunts plant growth and causes young leaves to curl or have necrotic leaf margins, and terminal buds and root tips to eventually die. New growth and tissues that are expanding quickly on the plant are typically the first to be harmed.

  • These include boron, copper, iron, manganese, molybdenum and zinc. Most nutrient deficiencies are caused by a lack of nutrient content in the growing medium or nutrient solution
  • Plants require calcium in order to develop new growth points and root tips. Symptoms of a deficiency include decreased growth in new leaf, buds, and roots. Younger leaves curl downward and develop tip burn, which is the browning of the leaf edges and tips.
