“Coordination and Control ” Explore the key concepts of coordination and control in management, focusing on aligning resources, optimizing processes, and ensuring organizational efficiency and success.
Class 12th Biology Chapter 3 Notes
The remodeling of bone is a function of which cells: Osteoblasts and osteoclasts
Abscisic acid can be sprayed on tee crops to regulate: Fruit drop
A cluster of neuron’s cell bodies form: Ganglia
In skletal muscle, calcium facilitates contraction by binding to: Actin
In myelinated neurons the impulse jumps from node to node (node of Ranvier) This is called: Saltatory impulse
The disorder in which bones are porous and thin but bone composition normal is: Osteoporosis
Who was the first to propose an objective definition of instincts in terms of animal behaviour: Darwin
Biorhythms are called circadian which means about one day so they are also called: Diurnal rhythms
The main transmitter for synapses that lie outside the central nervous system is: Acetylcholine
Cortisol brings about an increase in blood glucose level mainly by its production from protein and by: Insulin
Which of the following statements conserning the role of Ca+2 inthe contraction of skeletal muscle is correct: A rise in inter cellular Ca+2 allows actin to interact with myosin
Antidiuretic hormone is also called: Vasopressin
The funnction of the tubules in muscle contraction is to: Make the action potential deep into the muscle cells
Each type of the principal type of sensation that we can experience e.g pain touch sight sound and so for this called a modality of: Sensation
The concentrations of cell bodies of neuron are: Ganglia
The simplest form of learning is: Habituation
The organic portion of bones matrix is important in providing all but: Tensile strength
The sites where nerve impulse is transmitted from the nerve endings to the skeleton muscle cell membranes are the: Neucromuscular junctions
Myoglobin has a special function in muscle tissue: It holds a reserve supply of oxygen in the muscle
Excess MSH is secreted in: Addison’s disease
Cytokinins delay the aging of fresh leaf crops such as cabbage and lettuce as well as keeping flowers: Fresh
Innate behaviour is a collection of responses that are predetermined by the: Inheritance
The structure in human brain which control hunger is: Hypothalamus
The receptor cells of Planaria are sensitive to: Touch , pressure and chemicals
In neurons the message is transmitted across synapse in the form of chemical messenger called: Neurotransmitters
Nociceptors produce sensation of: Pain
Alzhelimer’s disease is: Mental illness
Nissl’s granules are group of: Ribosomes
The concentrations of cell bodies of neuron are: Ganglia
Excess MSH is secreted in: Addison’s disease
The part of human limbic system: Amygdata
Cortisol brings about an increase in blood glucose level mainly by its production from protein and by: Insulin
