Research and identify a vestigial structure of an organism of your choosing.
Mariana [72]

Answer:

The one of best example would be appendix in humans.

Explanation:

In the past, the appendix may have helped in the digestion of the plants by producing mucus and prevent any type of infection. Plants with a high content of cellulose are digested with the help of the appendix as reported.

It is not a part of the human digestive system and considers as a vestigial organ. Vestigial organs are the organs that are present in an organism with no particular function and their removal will not lead to any harm. Humans do not need it because our digestive system is more efficient and works better in the first stages of digestion than they used to.

Thus, the correct answer is - appendix in humans.

What percent of iodine has decayed if 5 half lives have passed?
goldfiish [28.3K]

Hello!

A half-life is the amount of time it takes half of an element to decay. For example, after one of carbon's half-life, half of carbon would've decayed.

Now, we can calculate how much has decayed if 5 half lives have passed.

1 -> 50% (1) -> 25% (2) -> 12.5% (3) -> 6.25% (4) -> 3.125% (5)

Therefore, there would be 3.125% left of iodine. However, your question is asking what percent has decayed. Therefore, subtract 3.125 from 100% to get your final answer.

100 - 3.125 = 96.875

Therefore, your final answer is 96.875% of iodine has decayed if 5 half lives have passed.

Hope this helps!

Paha777 [63]

Answer:

Tropical dry Climate: The weather is sunny pretty much all year. The ocean + the sun allows a tropical place to be great for growing food. Things such as coconuts and mangoes can be found. Its a great place to vacate because of the sunny climate, also clients will fall in LOVE with the warm beaches. Some activities would be to surf, sunbathe, and study the natrual habitat. The animals are also very interesting. Monkeys and chameleons would be great temporary pets to take care of.

I hope this was good enough, god bless you!!
