Answer:

The correct answer is -The brain and the spinal cord respond and sends a signal down a motor neuron to a specific sensory stimulus.

Explanation:

Sensory receptors sense the changes that take place in the environment that is called stimuli by sensory neurons that transmit the signal from the sensory receptors to the brain.

The brain and the spinal cord make the central nervous system. This coordinates a response to a specific stimulus and sends a signal down a motor neuron and send a signal to the effector by motor neurons.

Match the tissue with its primary fuel source: 1) brain A) fatty acids 2) resting skeletal muscle B) glucose 3) heart C) glucose
Dahasolnce [82]

Answer:

a) 1:B; 2:C; 3:A; 4:B; 5:C

Explanation:

Primary fuel source for tissues can be defind as the source of energy required for proper functioning of different tissues.

Brain consider glucose, a form of sugar to fuel cellular activities. Food provide glucose energy and through blood brain cell recieves the glucose.

Primary fuel source in resting skeletal muscle are glucose, fatty acids, amino acids that depends on the muscular activity and further participate in the citric acid cycle for oxidation to CO2.

Primary fuel of heart is fatty acids which carry important beta-oxidation equipment and serve as fuel for heart functions.

Glucose is the primary source of energy for adipose tissue which on breakdown contribute to ATP synthesis.

Liver utilises fatty acids, glucose and amino acids as primary fuel source.  When glucose is present in high quanity, it converted into fatty acids.

Hence, the correct option is a) 1:B; 2:C; 3:A; 4:B; 5:C

What happens to excess fatty acids and glycerol in the body?​
bogdanovich [222]

Answer:

This process, called lipolysis, takes place in the cytoplasm. The resulting fatty acids are oxidized by β-oxidation into acetyl CoA, which is used by the Krebs cycle. The glycerol that is released from triglycerides after lipolysis directly enters the glycolysis pathway as DHAP.

Which one of these is Not an example of intercellular communication
uranmaximum [27]

The correct answer is option A, " Energy production"

Reason:

The intracellular communication is the process through which one cell interacts with other cell for proper functioning of the body. The two major types of intracellular interaction involve:

a) Chemical Synapse – In this a chemical released by one cell is detected by receptor on another cell. For example the transmission of sodium and potassium ion across the membrane through the binding of Acetylcholine (Ach) with ACh receptors.  

b) Electrical Synapse – In this the cell which are connected through non selective, low – resistance pore between pre- and postsynaptic neurons known as gap junction.  

This is the case in option B, C and D.
