Hi, thank you for posting your question here at Brainly.
Chromatin contains proteins and DNA. The cellular division processes, mitosis and meiosis, condenses the chromatin to form chromosomes. They divide into two cells (mitosis), then two 4 cells (meiosis). The chromosomes contain the gene.
Human Immunodeficiency Virus is your answer
Answer: because they canńot see the animal if they are in camouflage.
Explanation:
Answer:
heart muscle
, skeletal muscle
, glandula and smooth muscle
Explanation:
The peripheral system distinguishes two major divisions: the afferent and the efferent. Afferent division is formed by the nerves that carry information to the central nervous system. In the efferent division the information travels from the central system to the effector organs, both muscular and other (including skeletal muscle, heart, glands, smooth muscle). Within the efferent division, in turn, two systems are distinguished, the somatic and the visceral or autonomous.
The somatic system conducts the signals that give rise to body movements and actions outside the body. It is formed by the fibers of the motor neurons that innervate the skeletal muscles; Their cell bodies are found in the spinal cord and a single axon reaches the muscle fibers it innervates. The action of these motor neurons always consists in the excitation and contraction of the muscles, although muscular activity can be inhibited by inhibitory synapses in charge of central system neurons.
The visceral system is formed by the fibers that innervate the smooth muscles, the heart, the glands and other non-motor organs or tissues, such as brown fat. It controls functions that are mainly related to the maintenance of internal environment conditions and also certain automatic responses to external stimuli. Regulates visceral activities such as circulation, digestion, thermoregulation.
