choose all the answer that apply which of the following are general characteristics of animal specialized tissuespinal cordnervous system autotropic mobility ​

Specialized tissues are groups of cells that have a common structure and function within an animal's body. Among the options given – spinal cord, nervous system, and autotrophic mobility – only the spinal cord and nervous system are examples of specialized tissues.

1. Spinal Cord: The spinal cord is a long, thin, tubular structure composed of nervous tissue, which extends from the brain and is enclosed in the vertebral column. It is part of the central nervous system (CNS) and helps transmit neural signals between the brain and the rest of the body. It is certainly a specialized tissue.

2. Nervous System: The nervous system is a complex network of nerves and specialized cells called neurons that transmit signals between different parts of the body. It is responsible for coordinating voluntary and involuntary actions and communicates signals to and from different body parts. The nervous system includes the brain, spinal cord, and peripheral nerves; it is a prime example of specialized tissue.

"Autotrophic mobility" does not refer to a type of tissue. In fact, it appears to be a misnomer because "autotrophic" refers to organisms that can produce their own food from inorganic substances (like plants through photosynthesis), and it is not related to the mobility or specialized tissues of animals, which are heterotrophic (they obtain food by consuming other organisms). Therefore, this option does not apply.
