Answer;

-Fossil evidence

-Comparative anatomy

-Molecular clocks

Biological evidence of the age of the earth includes fossil evidence, comparative anatomy, and molecular clocks.

Explanation;

-Fossils are critical tools in science because they give us clues to the types of plants and animals that lived on Earth in the past.There are many examples of fossils found on separate continents and nowhere else, suggesting the continents were once joined.

-Comparative anatomy is an important tool that helps determine evolutionary relationships between organisms and whether or not they share common ancestors. However, it is also important evidence for evolution. Anatomical similarities between organisms support the idea that these organisms evolved from a common ancestor.

-Scientists can use relaxed-clock methods to deal with variation in the rate of the molecular clock. By measuring the patterns of evolutionary rate variation among organisms, they can also gain valuable insight into the biological processes that determine how quickly the molecular clock ticks.

The cytochrome c in both horses and pigeons differs from the human protein at 12 locations. Based on this data, you might infer
yuradex [85]

Answer:

Cytochrome c is an enzyme found in bacteria, fungi, plants and animals. Here it is given that the human amino acid sequence for cytochrome c differs at 12 locations from the sequence in horses and pigeons. This information might be useful for inferring in preliminary stages that horses and pigeons are closely related to each other since they both show similar amount of difference from humans.

However, this hypothesis is being made with respect to the the comparison between "humans and horses" and "humans and pigeons". To further test this hypothesis pigeons and horses should be directly compared to each other without the use of a third species like humans. Hence, the sequence for cytochrome c in horse and pigeon should be compared with each other rather than comparing to humans.

Which of these products are made from a renewable resource?
aleksandr82 [10.1K]

Renewable resources are those which can be replaced naturally and repeatedly. For example, water, oxygen, and plants are examples of renewable resources.

Wood is a renewable resource as it is a part of trees. Trees are able to be replanted and can be cut down again, once they reach maturity. Plastics, glass, and steel are known as non-renewable resources as they cannot be replaced at a sufficient rate and usually have a limited supply. For example, plastics are created using a variety of different substances such as natural gas and oil (polyethylene). The Earth contains a limited supply of both substances, so plastic is deemed as being non-renewable.

As a result, the only renewable product in the choices provided above is a wooden spoon.
