There is three types of neurons occur. Sensory neurons typically have a long denfrite and short axon, and carry messages from sensory repeptprs to the central nervous system. Motor neurons have a long axon and short dendrites and teansmit messages from the central nervous system to the muscles.
Answer:
1. Apoplastic
2. Symplastic
3. Symplastic
4. Apoplastic
Explanation:
The interconnected porous cell walls of plant cells make apoplast along which water is allowed to move freely. Symplast refers to the path made up of interconnected cytoplasm of many plant cells connected by plasmodesmata. Therefore, water and dissolved minerals enter the root cortex from the epidermis in the solution can move through symplast and apoplast till endodermis.
Water and dissolved minerals present in the cytoplasm of cortical cells move from one cell to next via plasmodesmata (the symplast) while the ones present in their cell walls and intercellular space move through apoplast. The presence of casparian strips in the endodermal cell wall does not allow the movement of water and minerals through the apoplast.
<h2>Region between 2 and 3</h2>
Explanation:
Muscles consists of two protein filaments:a thick filament which is made up of protein myosin whereas a thin filament is made up of protein actin
- During contraction,thin filaments slide past the thick filament resulting in shortening of sarcomere
- Myosin thick filaments grab on to the actin filaments by forming cross bridges
- The thick filaments pull the thin filaments past them making the sarcomere shorter
- The region between points 2 and 3 includes the area of overlap between thin and thick filaments
