The chromosomes would not be duplicated and meiosis would not be able to be completed after meiosis 1 (meiosis 1 could still occur as the gametes go from diploid to haploid).
These abnormalities occur in the serotonin system which reduces and/or inhibits control in their movement. This disruption of the neurotransmitter causes them to act maladaptively. Thank you for your question. Please don't hesitate to ask in Brainly your queries.
A. Proteins
Most scientists thought protein was the genetic material because they were macromolecules.
Turkey foods contain all of the essential amino acids in relatively the same amounts that the human body requires. Proteins are fundamental macronutrients.

Answer:B The nervous system controls the speed at which food moves through the digestive system
Explanation:During digestion,the nervous system helps to control the actions that takes place.they stimulate digestive juices and the muscles of digestive organs.
The extrinsic nerves comes to the digestive tract from the brain and the spinal cord.they release chemicals; acetylcholine and adrenaline.
Acetylcholine causes the muscles of the digestive organs to squeeze and push the food through the tract.adrenaline relaxes the muscles and reduces blood flow to the organs.these occurs unconsciously.
The intrinsic nerves acts to speed up or delay the movement of food in the digestive tract and also the production of digestive juices.
