Are Burmese pythons taking over Florida? Burmese pythons (Python molurus bivittatus) are constricting snakes that can reach enor
LuckyWell [14K]

Answer:

1. It is now illegal to import or purchase Burmese pythons in Florida. Probably, at some point, python owners who no longer wanted to care for them let them go in the Everglades. By the mid-1990s, the pythons had established a breeding population.

2. There have been no human deaths from wild-living Burmese pythons in Florida. Overall, the risk of attack is very low. ... The simplest and most sure-fire way to reduce the risk of human fatalities is to avoid interacting with a large constrictor.

Explanation:

Burmese pythons are not poisonous snakes, however they are constrictors, coiling around their prey and squeezing the life out of it. The officials in the state of Florida are extremely concerned about the invasion of these large snakes and their ability to take over most of the Everglades.

Answer:

primary

Explanation:

Primary succession occurs when new land is formed or bare rock is exposed, providing a habitat that can be colonized for the first time. For example, primary succession may take place following the eruption of volcanoes, such as those on the Big Island of Hawaii. As lava flows into the ocean, new rock is formed.

Why was iodine able to diffuse across the membrane while starch was not?
Vikentia [17]
Starch cannot diffuse across the membrane because starch molecules are too large to fit through the pores in the dialysis tubing, whereas iodine is a smaller molecule and therefore can diffuse across.
