Answer: False
Explanation:
The genetically modified organisms are the organisms in which the genetic make up of the organism is altered. So that these organisms produce better yield and so as to improve their quality. The aim of genetic engineering in organisms is to develop or introduce a new trait in the organisms, which does not occur in the natural species. Thus the given statement is false as genetically modified organisms are reproducible.
Convection currents are caused by the colliding of cold and warm air. At night, air above water is warm and air above land is cold. The opposite is true in daytime. When the warm air hits the cold air, which is more dense, it is pushed upward. Then it travels laterally until it cools. It comes back down and pushes up the former cold air, which is now warm. This repeats many times.

Answer:
Independent assortment is random and occurs during Metaphase I of meiosis. There are two possible alignments for the chromosomes.
The answers are;
The muscular contractions are wave-like
The muscular contractions are entirely involuntary
This action is called peristalsis.
It is powered by the expansion and contraction of the smooth muscles present in the esophagus. It is controlled by the sympathetic activity of the autonomic nervous system hence
the movements are involuntary.
