In alpha decay, the nucleus loses two protons. In beta decay, the nucleus either loses a proton or gains a proton. In gamma decay, no change in proton number occurs, so the atom does not become a different element. ... If it loses two protons through alpha decay, it will have 82 protons

Compare the biomes of New York City and Seattle. Whey are their biomes different?
exis [7]

Answer:

New York City: temperate deciduous forest

Seattle: temperate wet forest

Explanation:

New York City is characterized by a <u>Temperate Deciduous Forest biome</u>. This indicates that its climate is not stable but, instead, faces constant changes. The seasons are clear and marked, e.g. summer is warmer and trees begin to lose their leaves during fall (as it is supposed to be). New York's biome is also characterized by the presence of rain throughout the year. Plants such as conifers and mosses are predominant and wildlife species like red foxes, squirrels, and owls inhabit in this city / biome.

Seattle, on the other hand, is characterized by a T<u>emperate Wet Forest biome</u>, that is, warm and dry-summer subtropical climate. The seasons are marked but not as predominantly as in New York. Seattle is also characterized by more humid conditions in contrast to New York. Moreover, summers tend to be drier and warmer, making it more vulnerable to bushfires. Plants such as the western red cedar and the ponderosa pine are predominant and wildlife species like deers, coyotes, and bears inhabit in this region.

A hypothesis is a starting point for further investigation, therefore a hypothesis will always be a possibility at least until it is tested.

Variable is a factor that is liable to vary or change.

A hypothesis without being tested is merely a statement or an explanation made on the basis of limited evidence. Therefore it is unsure whether the said statement is true or not.

A hypothesis can still be proven by further investigation with different variables

Which of the following make mechanical obstruction of the intestinal lumen of the small or large bowel an acute emergency?
Julli [10]

Distention from accumulating gas and fluid impede venous return, leading to bowel wall ischemia.

<u>Explanation:</u>

When the bowel lumen is obstructed, the gases and fuids starts accumulating as a repose to the obstruction. The accumulated fluid and gases results in the swelling or enlargement. This will result in the production of electrolytes and water inside the mumen that is in obstruction. The wall of the bowle will also enlarge and becomes swollen.

As more and more fluid and gas gets accumulated in the bowel, the bowel wall will be enlarged and as there is an increase in the pressure due to this accumulation, the fluid starts to leak from the wall. This will enter peritoneum and necrosis. This will result in an acute emergency when it becomes serious.
