Correct Answer: Glucagon
Correct Answer: The Spinal Chord
Explanation:
A reflex arc is a neural pathway that controls a reflex. In vertebrates, most sensory neurons do not pass directly into the brain, but synapse in the spinal cord. This allows for faster reflex actions to occur by activating spinal motor neurons without the delay of routing signals through the brain.
Correct Answer: Near Sightedness
Correct Answer: Orange
Correct Answer: Femur
Correct Answer: Nucleotides
Explanation:
Genes: The DNA is the genetic material. The DNA is made of several nucleotides. A nucleotide means, one nitrogenous base one sugar molecule and a phosphate molecule. These Nucleotides occur in sequences and several nucleotides form one gene ( a functional gene is called a cistron)
Correct Answer: holozoic
Explanation:
The feeding mechanism is of several types. If it is entirely plant-like (photosynthesis),it is called holophytic. It is entirely (holo) animal-like (zoic), that is devouring already existing food, it is called holozoic.
Correct Answer: mumps
Explanation:
Mumps: This is a swelling caused by inflammation of parotid glands placed in front of our ear region. The Inflammation is caused by a virus.
Correct Answer: blood does not have a respiratory function
Explanation:
The blood of some invertebrate animals like the earthworm is red due to haemoglobin pigment, but the pigment is dissolved in the plasma. In vertebrates the same pigment is found in the red corpuscles and not in the plasma.
Correct Answer: Sensation
Explanation:
Sensation is the activation of the receptors by stimuli.
