It is true <span>that a change in membrane permeability or ion concentration will change the resting membrane potential. A resting neuron has a voltage across its membrane called the resting membrane potential. The resting potential is determined by the concentration gradient of ions across the membrane and by membrane permeability to each type of ion. In aresting neuron, there are concentrations gradients across the membrane for Na+ and K+. Ions move down their gradients via channels, leading to a separation of charge that ceates the resting potential.</span>
Answer:
C. Carbon dioxide is a waste in cellular respiration in BOTH plants and animals
Explanation:
Cellular respiration occurs in animals and plants. It breaks down sugar in the presence of oxygen to release energy in the form of ATP. This process releases carbon dioxide and water as waste products.
Answer:
The answer is B.
Explanation:
Recent common ancestry.
The more closely related two different organisms are, the more recently they shared a common ancestor.
Answer:
Mercury: it has a crater-filled surface, with very high temperatures since it is closest to the sun; has a very thin atmosphere.
Venus: also very hot with high pressures and a very thick atmosphere compared to other terrestrial planets; slightly smaller than Earth.
Earth: only known planet to support life; mostly water but with many large landmasses, as well.
The moon: crater-filled; gets its light by reflecting the light from the sun.
Mars: aka the Rusty planet, it sports a red color due to iron oxide; has valleys and volcanoes; colder than Earth.
Jupiter: largest planet, with a swirling atmosphere and many different cloud formations; has storms and 63 moons; gas giant.
Saturn: also a gas giant; most known for its rings that are made up of particles that were attracted by the planet's gravitational pull.
Uranus: known as the ice giant with a large atmosphere of methane, as well as a faint ring system.
Neptune: also very cold, and named the blue planet; the interior is mainly methane ice; has a faint ring system and 13 moons.
