Answer:
TISSUES
Explanation:
Each cell type has a special feature that enables it to perform a particular function efficiently. These cells are said to be specialized to perform specific functions. Groups of specialized cells are assembled together to form a tissue. Examples are muscle, skeletal and nervous tissues in animals as well as phloem, epidermis and xylem tissues in plants.
There are 4 factors for evolution: mutation, gene flow, genetic drift, and natural selection. Natural selection is the strongest

Answer:
Your nervous system is involved with all aspects of human function. Circulation, digestion, endocrine and excretory systems are controlled by the autonomic nervous system. The autonomic nervous function is controlled by your body with out conscious thought. Imagine having to regulate your heart rate, rate of digestion, liver, and hormones with your mind. The brain and spinal cord work together to carry out these tasks.
Breathing is another example of your body systems working together. When you breathe, you think of the respiratory system. However, think about what the respiratory system does. It delivers oxygen (nutrients) and removes carbon dioxide (waste). However, the respiratory system only exchanges these gases through the lungs. These gases need to travel throughout the entire body. The circulatory system allows the gases (and blood) to travel everywhere. The skeletal and muscular systems are also involved because they help push the blood from one end of the body to the other.
the skeletal system and its interaction with the nervous system. For example, the skull protects the brain from injury. The brain also regulates the position of the bones by using the muscular system
A third example is when a pathogen enters the body. Your immune system is responsible for keeping invaders out. When you breath in a pathogen, it can sometimes cause you to cough. Your immune system recognizes the invader and communicates to your body that it is bad. Then your skeletal and muscular system is responsible for creating the contractions to create the cough.
