After receiving a stimus, the sensory receptors send(s) signals to the appropriate area of the body.
the must be sensory neurons.
hope its help..

<span>Hornworts are needle-like sporophytes that are a part of the group of bryophytes or non-vascular plants. They have horn-like or needle-like structures that have a flattened green plant body. These hornworts may be found all over the world but can only grow in places that are damp and humid. Some of its other species grow in large numbers as tiny weeds in garden soils and cultivated fields. While others in the tropical and subtropical areas grow on barks of trees.<span>

Answer:
They orbit around the nucleus of an atom.
Explanation:
Protons are located inside of the nucleus. Electrons orbit the nucleus.
Answer:
2/3 of the progeny would be green
Explanation:
Lethal alleles means that their presence result in death of the organism
Assuming this Lethal allele is recessive --> a
This way, if there is AA or Aa the plant will survive, otherwise if there is aa the plant will not survive
Than, assuming AA is a progeny white and Aa is green
Aa x Aa
2/3 Aa - Green
1/3 - White
1/3 - plant will not survive
Crossing 2 green progeny with each other
Aa x Aa
2/3 - Green
Answer:
B) astrocytes
Explanation:
Cells other than neurons that play an important role in the normal functioning of nervous system are called Neuroglia or glial cells.
Satellite cells, astrocytes, schwann cells and oligodendrocytes are all examples of glial cells.
⇒Satellite cells provide protection and nutrition to cells in peripheral nervous system ( peripheral nerves and ganglia).
⇒<em><u>Astrocytes</u></em> play an important role in central nervous system (brain and spinal cord). They provide protection to neurons, scavenge ions, form the blood-brain barrier and also maintain extracellular environment suitable for neuronal functioning.
⇒Schwann cells are found in the peripheral nervous system and myelinate the axons of neurons.
⇒Oligodendrocytes are found in central nervous system and produce myelin sheath which myelinates (insulates) axons of neurons. Their function is similar to schwann cells but in the central nervous system.
From the above discussion it is clear that the answer is B) Astrocytes as these maintain a suitable chemical environment for the neurons.
