Hi There!
Question - Charged particles from the solar wind come closest to Earth at the equator, where Earth’s magnetic field lines dip down to the Earth’s surface.
Answer - False
Why - Charged particles actually do the opposite of what it states in the question. Charged particles dip down to the Earths Surface and Earths magnetiv fields from the solar wind come closest to Earth.
Hope This Helps :)
Answer;
-Positive charge
Prior to the arrival of a signal from a presynaptic input, the post-synaptic membrane is polar with a greater relative positive charge to the ECF
Explanation;
-Neurons talk to each other across synapses. In somatic neurons, an action potential arrives at the synapse causing synaptic vesicles to fuse with the presynaptic membrane. The pre-synaptic membrane releases acetyl choline via exocytosis into the extracellular of the synaptic cleft.
-The ACh diffuses across the cleft and binds to the ligand-regulated sodium channels. Activated sodium channels allow a rapid diffusion down its electrochemical gradient towards the ICF. The movement of positive charges to the ICT causes the relative charge across the membrane to become positive on the inner surface.
Answer:
Plant cells have cell walls, constructed outside the cell membrane and composed of cellulose, hemicelluloses, and pectin, a cell membrane similar to that of the animal cell, a large central vacuole, a water-filled volume enclosed by a membrane known as the tonoplast, they contain plastids, the most notable being chloroplasts, which contain the green-colored pigment chlorophyll that converts the energy of sunlight into chemical energy, and then all the other organelles of the animal cell (mitochondria, endoplasmic reticulum, nucleus and nucleolus, golgi apparatus, etc.)
