Answer;
- 100
Researchers have identified about 100 substances that are made in our body and brain that act as neurotransmitters.
Explanation;
-Neurotransmitters are the chemicals which allow the transmission of signals from one neuron to the next across synapses. They are also found at the axon endings of motor neurons, where they stimulate the muscle fibers.
-Neurotransmitters enable neurotransmission, which is the process by which signaling molecules (neurotransmitters) are released by the axon terminal of a neuron (the presynaptic neuron), and bind to and activate the receptors on the dendrites of another neuron.
They don't require big ones because they're able to keep moving and provide food and energy for themselves while plant feels are not able to do the same, thus giving them lather vacuoles.
BamHI is a type II restriction endonuclease, ensuring the dimensions
for recognizing short arrangements of DNA and cutting them at a target site. It
transmits various type II endonuclease, replicating DNA, and possibly handling
DNA mutation-derived infections through genetic therapy.
Environmental factors are more likely to affect phenotype than genotype.
Phenotype refers to the observable physical characteristics of an organism, a product of the genetic information contained in the genotype, in accordance with the conditions of the determined environment in which the organism lives.
- The phenotype supposes the manifestation of the genotype based on the environmental factors, the traits expressed by the phenotype are behavioral and physical.
- Regardless of the genotypic information manifested, environmental factors will also shape the phenotype of an organism, since it can suffer accidents, changes or adaptations that a genetically similar individual but in another environment would not suffer.
Therefore, we can conclude that the phenotype is the variable expression of a genotype in accordance with the environmental factors.
