Answer: 4,000 years ago

The parachute was invented 4,000 years ago, when Chinese observers noticed that air resistance slowed free-falls. Legend states that a safe jump was made from a granary using two bamboo hats. In the 800s, Abbas Ibn "Armen" Firnas jumped off a tower in Cordova (Iberian peninsula) using a large cloak like a wing.

what probability do we have of obtaining a purple flower (Rr), when we combine two blue flowers (rr) in an incomplete Dominance
34kurt

Answer: none

Explanation:

If we have that the color characteristic is regulated by the dominant gene R, by crossing two blue flowers with the recessive gene r, no violet flower will be obtained, since the rule of incomplete dominance describes that phenotypes can be obtained intermediates of homozygous parents, however in the case, we only have 2 parents with the same recessive conditions, which do not contribute to generate the violet, to produce one of the parents should have a gene that expresses the color red

nikitadnepr [17]
<h3>Your answer is D.</h3>

The insects are the same species.

<h3>Explanation:</h3>

A species is a group of similar organisms able to reproduce (to exchange genes and interbreed) only within the group. That means that organisms from different species could not exchange genes. Since mentioned insect groups are able to reproduce and produce offspring that could also breed, these groups belong to the same species. If they could not reproduce and produce offspring that could also breed, these groups would belong to the different species.

I hope I helped, and I always appreciate Brainliest!!! :)

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.
