Answer:

Option (4)

Explanation:

The shells of invertebrates are often embedded in the mudstone rocks and are found in the present days. These imprints are formed when these organisms moved from one place to another and are covered with sediments, forming fossil imprints.

Teeth are considered as fossils because they undergo the permineralization process, in the absence of oxygen and decomposers.

Mummified sloths were the mammal that existed in the geological past, and their fossils are still found at some places (including caves) on earth. The sediments played a key role in covering the organisms preventing the oxygen-rich environment and from getting decomposed.

Thus, all of these are fossils, so option (4) is the correct answer.

PLEASE HELP!!!! <br> Which best describes President Carter’s attempts to free the hostages in Iran?
Salsk061 [2.6K]

C is the correct answer. All of the attempts were failed.


In April 1980, frustrated with the slow pace of diplomacy (and over the objections of several of his advisers), Carter decided to launch a risky military rescue mission known as Operation Eagle Claw. The operation was supposed to send an elite rescue team into the embassy compound. However, a severe desert sandstorm on the day of the mission caused several helicopters to malfunction, including one that veered into a large transport plane during takeoff. Eight American servicemen were killed in the accident, and Operation Eagle Claw was aborted.

President Carter continued to attempt to secure the hostages' release before his presidency's end. On 20 January 1981, minutes after Carter's term ended, the 52 US captives held in Iran were released, ending the 444-day Iran hostage crisis.
