The difference that exists between the inner and outer planets is - D. None of the inner planets have rings, whereas all the outer planets have rings.
Planets in the solar system are divided into two groups on the basis of distance from the sun are Inner planets and outer planets. The inner planets are closer to the sun compared to the outer planets.
Inner planets:
- include four planets - Mercury, Venus, Earth, and Mars.
- Also called terrestrial planets
- small and rockier
- very less or no natural satellites
- No rings around them
Outer planets:
- include Jupiter, Saturn, Uranus, and Neptune
- called gaseous planets
- larger and gaseous (hydrogen or helium)
- numerous satellites
- found rings around them.
Thus, the correct option: D. None of the inner planets have rings, whereas all the outer planets have rings.

Answer: Hydrophobic
Explanation:
Think about how water reacts with oil. When you mix the two the oil would stay in little drops within the water so they are not mixing. The tails of the membrane prevent water from leaking out by sticking together and not letting water through. Just to solidify this Phobia= fear, lipids are water "fearing".
Answer:
d. more permeable to sodium ions.
Explanation:
The binding of Acetylcholine with the receptors at motor end plate facilitate membrane permeability to sodium ions therefore opening of voltage gated channels for sodium ions.
Sodium ions diffused into the synapse of post synaptic neuron at the neuromuscular junction.
If the stimulus is up to threshold levels; more chemical(neurotransmitter) gated sodium channels opens, and sodium ions move into the synapse to depolarize the membrane with reversal of charges to generate action potential.
The continuous binding of Acetycholine , leads to permanent opening of sodium ions,and over excitation from depolarization. Acetycholinesterase enzymes breakdown Acetycholine to choline and Acetyl Co -A. These are recycle back to Acetycholiine
Answer:
True
Explanation:
Memory is formed by creating new neural pathways from stimuli we receive (smell, vision, auditory etc) to the brain where the pereception of it occurs.
Memory is defined as ability of the brain to encode, store, and retrieve information when needed. Memory forming is actually information processing that includes:
• sensory processor - sensing the information from the outside world ( chemical and physical stimuli)
• Working memory (short-term memory) - encoding (stimuli information) and retrieval processor (from previously stored material)
• Long-term memory - to store data through systems.
Answer:
Explanation:
Paleontologists are scientists that study the history/existence of past lives by collecting and examining fossils. They use these fossils to determine the history and age an organism has existed. Fossils are remains of dead organisms (plants and animals) which serve as evidence of past lives that have existed on earth in the past. They could include bone remains or footprint of this animals.
Fossils (from bones) are however mostly incomplete because they decompose before they are "stored naturally" by sediments which covers them. When scientists discover this incomplete fossils, they are compared (if there has been similar fossils discovered before then) and are stored and transferred to the lab for examination. This examination includes anatomical comparison (to determine relatedness with other fossils/organisms), carbon dating (to determine age) and data comparison (which includes location and type of soil and habitat).
