Fossils up to 75,000 years old can be dated with Carbon-14.
Radio isotopes can be used for the age determination of the fossils. Carbon-14 is a common isotope which is used for that purpose. But the half- life of the Carbon-14 is relatively small as 5730 years. That means the amount of Carbon-14 will be half after every 5730 years. Hence, decay is very fast. So Carbon-14 cannot be used forage determination which is more than 75000 years due to the low accuracy.
The answer is A.They contain different genes
False, I'd say. Mammals usually adapt based on environment. Now, I know predators are "apart" of the environment, but I don't think that'd be it. I'd bet more money on saying mammals evolve based on environment adaptation. Sorry if I didn't answer your question or if I didn't get my point across well.
The correct answer is letter C.
Bryophytes have biflagellate gametes and cuticle. The cuticle serves as the covering of the soft tissue of the plant which provides protection and prevents damages on the walls of the plants. The biflagellate gametes develop also as a form of protection as well. These plants have an aquatic ancestry because of their dependence on water for reproduction and survival.
