Answer:
For involuntary actions (reflexes) the information is first detected in the sensor and travels along sensory neurons to the spinal cord. Once the action potential reaches the spinal cord, the information is transmitted across the synapse to the motor neuron. for voluntary actions,
movements are commanded by the motor cortex, the zone of the cerebrum located behind the frontal lobe. The motor cortex sends a neural message that moves through the brain stem along the spinal cord and into the neural network to the muscle being commanded.
Answer:
The correct answer will be option- synaptonemal complex.
Explanation:
The tetrad arrangement of the genetic material in an organism is mediated by a highly conserved structure known as the synaptonemal complex. The synaptonemal complex is formed during the prophase I of the meiosis I which attaches the chromatin of the homologous chromosomes.
The synaptonemal complex is a proteinaceous structure which is formed by the two lateral ladders like elements with a central portion composed of the central element. The chromatin gets attached to the lateral elements while the central a portion bridge space between the two ladders thus help in the formation of the tetrad.
Thus, option- synaptonemal complex is the correct answer.
Abiotic: soil,sunlight, Thunderstorms, earthquake, temperature
Biotic: Competition, disease, prey symbiosis, water table

Answer:
If I'm understanding correctly, the answer to your question would be a biologist.
Explanation:
Biologists study things such as life, health, and diseases, and such meaning if you were a scientist studying coronavirus, you'd be a biologist, because it affects living creatures (human). They would try to create medicines to make humans immune to coronavirus. I'm not sure how to explain this much further, so that's all I have.
