The answer is; Jane would be right.
The atom was discovered be more of empty space. The mass of an atom is mainly attributed to the mass of the nucleus which occupies a very small fraction of the size of the atom. The nucleus is Located in the center surrounded by orbiting electrons.
The Geiger–Marsden experiment, where alpha particles are accelerated onto a thin aluminum foil proved this theory by Ernest Rutherford. Some of the particles were deflected by the foil and this was attributed to the dense nucleus of the aluminum atoms in the foil. The other particles passed through because most of the atoms are made of empty space.
Hi!!! I think the answer is B! Have a great rest of the day!!!
Answer:
A. supplementary motor cortex; premotor cortex
Explanation:
The supplementary motor cortex, also known as the supplementary motor area (SMA), is an area of the cerebral cortex located anterior to the premotor cortex. This area (SMA) is involved in the execution of complex and rapid sequential movements (e.g., typing). Moreover, the premotor cortex is an area of the motor cortex located between the primary motor cortex and the prefrontal cortex. This area (premotor cortex) is activated during motor tasks including, among others, spatial and sensory guidance of movement.
Answer:
"Fore-brain" is the part of the nervous system involved during solving the puzzle.
Explanation:
- Fore-brain is the part of the brain that covers the brain's central core.
- Fore-brain directly connects the upper and lower brain functions.
- Information after midbrain and hindbrain travels to fore-brain.
- It consists of two areas:
- Thalamus, Limbic and hypothalamus system.
- cerebral cortex.
- Fore-brain influences emotion, mood, motivation and sensation of pleasure and pain.
<span>Water has a surface skin. Some insects are able to generate tiny bubbles under their bodies which makes them buoyant enough to not break thru the water's skin. This skin is also known as surface tension. </span><span>Some bugs and small objects (pins or paperclips, etc) can rest on the surface of the water due to surface tension. Water molecules are bipolar and attract each other forming a skin. The bug or paperclip make tiny depressions in the water skin which provides buoyancy. A detergent will ruin the water tension (because it is a wetting agent) and the bug or paperclip will sink.</span><span>
