Answer: Precipitation

Grasslands are characterized as lands covered by grasses rather than large shrubs or trees. Grasslands are found in regions which receives rainfall that are not enough for the growth of forests. Desert covers about one fifth of the Earth's surface and occur where rainfall is less than 50 cm/year. Rainfall are least frequent in deserts as compared to grassland. The desert-grassland boundaries can change as a result of precipitation. The fate of land form of boundary will be dependent upon precipitation. As, if the boundary receives moderate or sufficient rainfall to grow vegetation then it will be included in the grassland and if the boundary receives no or scanty rainfall then boundary will be included in desert region.

The missing part of the question is -

" Is this Primary or Secondary Succession?"

Answer:

The correct answer is - secondary succession.

Explanation:

Recolonization of the plant and animals to habitat after a major disturbance such as flood, lava eruption, wildfire, or human disturbance is characterized as secondary succession.

In this particular case, there is secondary succession occurs, there is man-made disturbance tajes place as logging company clear the spruce trees from a habitat, and after clearing the land the spruce seedlings began to sprout, birds, rabbits recolonize to the area.

Many foods must be refrigerated to prevent spoiling (microbial growth). Explain why honey (which is ∼82% carbohydrate by weight)
VLD [36.1K]

Answer;

-Honey contains a considerable amount of sugar (about 82% carbohydrate) and therefore when a microbe (e.g., a fungal spore or bacterium) lands on honey the process of osmosis causes water to be drawn out of the microbe thus blocking its ability to live and proliferate.

Explanation;

Antibiotics are used to kill or inhibit bacteria growth. Honey contains hydrogen peroxide, which may account for some of its antibacterial properties. It also has a high sugar content, which can help stop the growth of certain bacteria.

-Additionally, honey has a low pH level. This works to pull moisture away from bacteria, causing the bacteria to get dehydrated and die off.

A student measured the amount of oxygen and carbon dioxide dissolved in an aquarium containing an aquatic plant and a snail. Why
ratelena [41]

The answer is A. Putting the aquarium in the dark means that the aquatic plants will not be able to photosynthesize.  The process of photosynthesis produces oxygen as a by-product. The oxygen is used by the fishes in respiration and release carbon dioxide. The carbon dioxide is used by the aquatic plants in photosynthesis.

Marrrta [24]

Answer:

Some particles traveled through empty parts of the atom and some particles were deflected by small areas of high-density positive charge in atoms.

Explanation:

Rutherford concluded from his experiment that there are empty spaces present in most parts of the atom while a heavy positive charge is present in the nucleus of an atom due to which the tiny positively charged particles deflects because of positive-positive charge repulsion. Most of positively charged particles passes undeflected which indicated the presence of empty spaces in the atoms. The electrons revolve around the nucleus have no effect on the deflection of positively charged particles.
