If a person lacks one sense organ the brain concentrates on remaining sense organs and these sense organs become more sensitive.

  1. True

  2. False
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

  • If one sense is lost, the areas of the brain normally devoted to handling that sensory information do not go unused they get rewired and put to work processing other senses. 
  • A new study provides evidence of this rewiring in the brains of deaf people. The brain adapts to the loss by giving itself a makeover. Hence, If a person lacks one sense organ the brain concentrates on remaining sense organs and these sense organs become more sensitive.
So, the correct answer is 'true'.

Multiple choice biology life processes blood pressure circulatory system transportation in animal and plants

Excess of Na++ ions in human system causes____________________

  1. Diabetes

  2. Anemia

  3. Low blood pressure

  4. High blood pressure
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

  • The increasing of the concentration of Sodium ions in blood would attract water from the surrounding issues, because of the osmotic pressure.
The increasing of the total volume of blood makes the blood pressure higher.
Hence,

Option $D$ is the correct answer.

Multiple choice biology chemical messages for homeostasis hypothalamus nervous and endocrine system in humans coordination in human beings- chemical control

Hypothalamus does not control

  1. Hunger and satiety

  2. Thermoregulation

  3. Libido

  4. Creative thinking and consciousness

  5. Osmoregulation
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The hypothalamus regulates autonomic and endocrine functions like hunger, temperature, and osmoregulation. Higher cognitive functions like creative thinking and consciousness are primarily associated with the cerebral cortex.
