Answer:
The correct answer is - sensory neurons → inter-neurons → motor neurons.
Explanation:
The nerve system receives a signal from the external change or stimuli and transmitted it to the spinal cord and brain. The transmission of the signals or information is carried by three different types of nerve cells: sensory neurons, interneurons, and motor neurons.
Sensory neurons receive the signal from the external stimuli and converting it to the electrical impulses. Interneurons are the associative neurons that establish the connection between sensory neurons and motor neurons. Motor neurons are the efferent nerves that carry the signal from interneurons and brainstem or spinal cord and transmit to the muscles.
Thus, the correct answer is - sensory neurons → inter-neurons → motor neurons.
Answer:
The correct answer is: It allows large masses of food to pass through the esophagus when swallowing.
Explanation:
The trachea, or windpipe, is a hollow organ that <u>connects the larynx to the bronchi and allows the passage of air</u> so it can reach the lungs and make the gas exchange possible.
The trachea has cartilages around it to reinforce the tube for protection and to maintain the airway open. The places where there's cartilage are the anterior and the lateral sides of the trachea. This cartilage has the shape of an incomplete ring, or the shape of a C to allow the passage of food. The side that has no cartilage is the posterior side of the trachea, which is the side that is <u>in relation to the esophagus</u> - the part of the gastrointestinal tract that transports the food from the buccal cavity to the stomach.
Rr and rr in the ratio of 1:1
Explanation:
If allele for smooth seed is Dominant over the allele for wrinkled seeds, and they are crossed 50 per-cent of the progeny will be heterozygous dominant and 50 per-cent will be homozygous recessive.
Rr X rr
Rr Rr rr rr F1 generation.
r r
R rR rr
r Rr rr
From Punnet square it will be 50 per-cent chance each of rr and Rr.
I think the yellow arrows show a guide were it goes or maybe tissue fluids!
