Answer 1

Answer:

hey may❤✌✌

Explanation:

• muscular tissues
• electical impulses
• Brain and spinal cord
• Cerebrum
• lack of growth hormone(GH)secreted by pituitary gland(master gland).
• Tropic movement(chemotropism)

✒Hope it helps❤☺✌

Answer 2

The correct biological terms are as follows.

• 1) Control and coordination are functions of the nervous system and the muscle tissues in the body. Together, they control movement and responses to stimuli.
• 2) The nervous system uses electrical impulses to transmit messages. These impulses are called neural signals and help in various body responses.
• 3) The central nervous system consists of brain and spinal cord. They coordinate all nerve impulses and the working of the body.
• 4) Largest part of the brain is the cerebrum. It is divided into two vertical hemispheres and is involved in speech, memory, emotions, etc.
• 5) Deficiency of Growth hormone in childhood leads to dwarfism in humans. It is secreted by the pituitary gland and over-excretion can cause gigantism.
• 6) The growth of pollen tubes towards the ovules is the result of a chemotropic movement. This is due to chemical stimuli from the ovule to guide the pollen tube through the style into the ovule.
