b.cytokinins

c.abscisic acid

d.gibberelins

q11

a. testosterone ,oestrogen and progesterone

b.thyrotoxicosis

q12.

insulin glycogen

The production of pancreatic hormones, including insulin, somatostatin, gastrin, and glucagon, play an important role in maintaining sugar and salt balance in our bodies. Primary hormones secreted by the pancreas include: Gastrin: This hormone aids digestion by stimulating certain cells in the stomach to produce acid

q13

Nastic movements are non-directional responses to stimuli such as temperature and heat. ... →Tropic movement is the response to stimuli that comes from one direction. → It is a directional movement. →If the movement of the plant part is towards the stimulus, then it is known as positive tropism.

q14

a.the nerve pathway involved in a reflex action, including at its simplest a sensory nerve and a motor nerve with a synapse between

b.Adrenaline. Adrenaline is a hormone released from the adrenal glands and its major action, together with noradrenaline, is to prepare the body for 'fight or flight'.

nastic movement are the non directional movement of plant to the external stumuli. eg- when you touch mimosa pudica(chui mui)

Q14

(a) path followed during reflex arc is called reflex arc it involes sensory neuron>spinal cord>motor neuron>corresponding muscle

(b)adrenaline controls your body function in emergency situation it increases you breathing and heart rate , expand pupil and many more changes

(c) fore brain is the main part of brain it consist of mainly cerebrum which is responsible for thinking and manipulating and perform various activities, control pituitary gland and many more function you will study later

hope this help
