The lining of the back of eye containing two types of photoreceptor cells - rods - sensitive to dim light and black and white - and cones - sensitive to colour. A small area called the fovea in the middle of the retina has many more cones than rods.
Ok, particle is not a very nice word, no real sense of size associated with it
it can be a group of molecules like a speck of sand
referring to the molecules themselves
or refering to the atoms that make up the molecule
now in terms of phase change,
if we consider a speck- a group of molecules- then solids will expand when heated, however this definition falls flat in terms of phase change
ok, how about molecules, as molecules undergo phase change, the molecules in relation to each other will move apart from one another. Solid- molecules are bonded, Liquids- molecules are close and flow around each other, Gas- molecules are a significant distance from one another. But the increase in size when you heat up a molecule, i would have to say yes. adding heat increases energy which increases molecular vibration which would probably increase the overall average size to some unnoticeable degree.
now standalone atoms are just atoms, if you want to consider the electron cloud as size, then heating it up would negligibly cause the outer move outward. but it really depends on the scale of the question
Answer:
good afternoon
Explanation:
Environment means anything that surround us. It can be living (biotic) or non-living (abiotic) things. It includes physical, chemical and other natural forces. ... In the environment there are different interactions between animals, plants, soil, water, and other living and non-living things.
The answer is C (when they cannot interbreed) because when the new species cannot have offspring with the old species, they do not mix traits.
Midnight Sun, a name given the sun when it can be seen at midnight during the Arctic or Antarctic summer.The midnight sun occurs because the earth's axis tilts toward the sun in summer and away from the sun in winter. Thus the poles are exposed to the sun's rays for six months each. As our planet makes its annual circuit around the sun, parts of the globe experience dramatic seasonal swings thanks to the tilt of Earth’s axis. Between April and September, the northern hemisphere is tipped toward the sun, resulting in longer days and warmer weather. Destinations near and north of the Arctic Circle experience the astronomical phenomenon.
