Animals like sea turtles and dolphins would be found in the neritic zone.<br> T or F
Lelechka [254]

Answer:

T ~ True

Explanation:

The neritic zone is the region of shallow water (200 meters depth) above the continental shelf where light penetrates to the sea floor. Due to the abundant supply of sunlight and nutrients in this zone, it is the most productive ocean zone supporting the vast majority of marine life. As a result, many organisms that require light for photosynthesis can live in this zone, including seaweeds and phytoplankton. Most coral reefs are also found in the neritic zone. ... Swimming organisms in the pelagic zone include dolphins, whales, squid, and numerous species of fish adapted to life at different depths.

They usually have short life spans.

Thus, the most unlikely characteristics of pioneer species is that they have long life cycles with slower growth and longer life spans.

You find a fossil that you think is about 350 million years old. You decide to use 235U to date a volcanic ash bed just below th
snow_lady [41]

Answer:

Before answer this question, you need to know what is the half-life of a compound, the term half-life is defined as the time it takes for one-half of the atoms of a radioactive material to disintegrate. Knowing this you know that has passed half of the half-time, so you should probably have 25% of the original amount of 235U. This problem may be tricky because it says half of the time to reach the half-time, but 50% of the compound will be present in 750 million years after the death of the specimen.
