The two most widely used hallucinogens are lsd and mescaline. mdma and marijuana. nicotine and caffeine. alcohol and marijuana. marijuana and lsd.

Answers

The correct answer is alcohol and marijuana.

The first and fourth answers are not true at all, as lsd is not one of the most widely used hallucinogens, very few people do it.

mdma is ecstasy, which is also not a widely used hallucinogen.

While nicotine and caffeine seems to be a good answer, it is still incorrect as caffeine kind of just gives you a spring, it is not a hallucinogen.

So, the correct answer is alcohol and marijuana because they both impact how we believe things occur when under their influence. And, when you think of most widely used, especially illegally among teenagers, it is these two.

Explanation:

Which of the following structures of a vertebrae is the hole through which the spinal column passes?A.
Vertebral foramen
B.
Spinous process
C.
Intervertebral disks
D.
Vertebral arch

Answers

Answer:

The hole in the vertebrae and through which the spinal cord passes is called the vertebral foramen (option A).

Explanation:

The vertebral foramen is an orifice in the center of the vertebra that is bounded at the front by the body and the vertebral arch at the back.

This hole in the vertebra not only contains the spinal cord and the roots of the peripheral nerves, but also the membranes that cover it —meninges— vascular elements such as the venous plexuses and the anterior longitudinal ligament, which hold the vertebrae together.

The other options are not correct because:

    B. Spinous processes are bony eminences that are found on the posterior surface of the vertebrae, also called vertebral spinous apophyses.

    C. Intervertebral discs are structures that separate the vertebrae, avoiding their direct contact, allowing the movement of the spine.

    D. Vertebral arch corresponds to the posterior half of a vertebra.
