Answer:
The correct answer is option d) "No, the somatic nervous system is responsible for voluntary responses, and is not subdivided into sympathetic and parasympathetic components".
Explanation:
The somatic nervous system is responsible for the control of voluntary body movements via skeletal muscles. Also, the somatic nervous system is not subdivided into sympathetic and parasympathetic components. This subdivision corresponds to the autonomic nervous system, the system that influences the function of internal organs. Therefore the statement of the friend was incorrect.
A major environmental concern associated with GM crops is their potential to create new weeds through out-crossing with wild relatives, or simply by persisting in the wild themselves. The potential for the above to happen is assessed prior to introduction, and is monitored after the crop is planted as well.
Rheumatoid arthritis causes this. It's also a chronic disease.
A sprain is an injury to a ligament.
Osteoarthritis is a joint disease caused by the inflammation, breakdown and loss of the cartilage.

Hope this helps :).
Complete question:
You will find the image of the skulls in the attached files.
Answer:
1) 2 similarities between each of the skulls might be the presence of the nasal spine, and the interdental space.
2) The size of the skull seems to be the most noticeable change in skull anatomy between the dawn horse and the modern horse.
Explanation:
- Each of the nasal bones in horses ends in a protuberance named "the nasal spine". These spines converge in the distal portion of the bone. These spines and the incisive bone delimitates the space called the naso-incisor notch. In the attached figure you will see the nasal bone in red and the nasal spines. This structure is present in all the skulls in the same position.
- The interdental space is the space left between the front teeth and the back teeth. It is useful to recognize a male from a female in modern horses. This space can be found in all the skulls. You will see it in blue in the image.
The biggest change in skulls between the dawn horse and the modern horse is the size. The skull keeps the original shape or very similar shape but varies in length and height.
