Answer:
The neural pathway bringing temperature information from your left hand to the somatosensory cortex would have two synapses, with the first being in the <u>spinal cord dorsal horn on the left side</u> and the second being in the <u>thalamus on the right side.</u>
Explanation:
The stimuli received by the external receptors must travel from the place where they are produced to the association centers located in the central nervous system, where the information is processed.
In the case of the sensory nerves, which conduct the temperature-related information from the left hand, it happens that:
- They make their first synapse in the posterior horn of the spinal cord, responsible for receiving nerve impulses of sensitivity, on the same side as the stimulus (left).
- The second synapse occurs in the thalamus, an organ of the central nervous system that is responsible for receiving information related to temperature. As the sensory and motor pathways are crossed, the portion of the thalamus that receives the information is the right one.
One of the consequences of the crossing of the sensory pathways is that everything related to one side of the body is processed on the opposite side of the somatosensory cortex.

Answer: A. Cool
Explanation:
The diagram shows that moving from the left to the right indicates a lower temperature and the arrow is pointing to stars to the right which means that they are cool in comparison to those on the left.
Red stars like the one being pointed to are the cooler stars with temperatures of less than 6,000 Kelvin as opposed to blue stars which are very much hotter and go above 10,000 Kelvin.
Answer:
the rhythm of heart contractions.
Explanation:
In Human anatomy, cardiac cycle can be defined as a complete heartbeat of the human heart which comprises of sequential alternating contraction and relaxation of the atria and ventricles, therefore causing blood to flow unidirectionally (one direction) throughout the human body.
Generally, the cardiac cycle occurs in two (2) stages;
1. Diastole : in this stage, the ventricles is relaxed and would be filled with blood.
2. Systole: at this stage, the muscles contracts and thus, allow blood to be pushed through the atria.
An electrocardiogram (ECG) provides information about the rhythm of heart contractions.
Additionally, the right atrioventricular valve (AV) also referred to as the tricuspid valve is located on the right dorsal side of the human heart. The right atrioventricular valve (AV) comprises of three (3) leaflets (flaps) which opens and closes in order to allow for the flow of blood from the right atrium of the human heart to the right ventricle. Also, the right atrioventricular valve is saddled with the responsibility of preventing blood from flowing backward in the mammalian heart.
Answer:
Explanation:
DNA is deoxyribose nucleic acid. It is a double helical structure. It remains in the coiled form so as to make the information stored in the small region within the cell. The sequence of bases allows the information to be stored in the coded form so as to promote the synthesis of proteins. Complementary base pairing allows the DNA molecule to replicate itself.
