A paleontologist can use radiometric dating (also known as carbon dating), to determine the age of a fossil. They do this by measuring the decay of isotopes in either the fossil itself or the rocks associated with it. A carbon-14 isotope takes about<span> 5,730 years to halfway decay, knowing this information paleontologists can date a fossil by how long the fossil has been decaying with the use of special tools.

Answer:
Another type of evidence for evolution is the presence of structures in organisms that share the same basic form. For example, the bones in the appendages of a human, dog, bird, and whale all share the same overall construction ([Figure 2]). That similarity results from their origin in the appendages of a common ancestor.

Using a bullfrog as an example
Their common name is Bull frog, their scientific name is Lithobates catesbeianus
Major physical structures and color are: Strong legs for jumping, buldge-y eyes, slick skin. They are usually greenish brown.
Oops. I just saw the Siberian wood frog bit.
I need to go, but I hope my bullfrog example will help you answer your questions for Siberian wood frog. :)
“It is not always possible to find or buy organic fruits and vegetables in today's conditions. In order to purify pesticide residues in foods, the first thing that is usually done at home is to put these foods in vinegar water. However, vinegar water is not effective in reducing pesticide residues, but in reducing the microorganism burden. Studies have done that vinegar water increases the effectiveness of pesticide residues even more. The main purpose of adding vinegar to the washing water is to create an acidic washing environment and to remove the potentially harmful biological factors that can be found on the food in case of inadequate washing. However, many of the pesticides commonly used today cannot be removed from the food due to insufficient washing and are taken into thBe body. This causes pesticides to continue their harmful effects for long periods of time.
