The correct option to fill in the blanks in the passage is:

**DNA; proteins; amino acids**

So the completed passage would read:

“**DNA** contain(s) the codes (codons) for the creation of **proteins**, which is/are often called the ‘building block(s) of life.’ It/they combine(s) in long strings to create **amino acids**, which make(s) possible the basic functions of life on Earth.”

The statement that best describes the relationship of humans to these two organisms is:

**Humans have a more recent common ancestor with chimpanzees than they have with cows.**

This is supported by the fact that humans and chimpanzees share over 99% of their genetic material, indicating a much closer evolutionary relationship compared to the similarities shared between humans and cows.
Answered by GPT-4o mini
The correct response is:

**The two species have many similarities in their DNA sequences.**

In a cladogram, closely connected species imply a closer evolutionary relationship, which typically translates to greater genetic similarity.

The statement that best compares the evolutionary relationship of an elephant, a hedgehog, and a pig is:

**Pigs are more closely related to elephants than to hedgehogs.**

This is based on the fact that pigs (family Suidae) and elephants (order Proboscidea) belong to a group called Afrotheria, which suggests a closer evolutionary relationship compared to hedgehogs (order Erinaceomorpha).

The anatomical feature of an animal that is more likely to biodegrade over time and not become a fossil is:

**skin**

Skin is made up of soft tissues that decompose relatively quickly compared to harder structures like teeth, shells, or bones, which are more likely to be preserved as fossils.
Answered by GPT-4o mini
The response that best explains what makes it possible for scientists to discover how certain types of animals evolved in different environments is:

**the geographic location of fossils**

The geographic distribution of fossils helps scientists understand how organisms adapted to various environments over time and can provide insights into the evolutionary history of different species based on their fossilized remains found in particular locations.

The significance of archaeologists finding fossilized embryos of early Cambrian animals is:

**The discovery suggests that the basic building blocks of modern life already existed in Cambrian times.**

This finding indicates that the fundamental features of early development and the complexity of life were present during the Cambrian period, supporting the idea that many essential aspects of biological organization and development were established early in the history of life on Earth.
Answered by GPT-4o mini
The significance of human arms and bat wings developing in a similar manner is:

**It suggests the two species have common roots.**

This similarity in embryonic development is an example of homologous structures, indicating that both species share a common ancestor, highlighting the concept of evolutionary relationships among different species.
Answered by GPT-4o mini
The embryonic feature that suggests human beings and fish share a common ancestor is:

**Human embryos go through a stage during which tails and gills are formed.**

Both human and fish embryos exhibit similar developmental stages, including the formation of structures like tails and pharyngeal (gill) arches, which indicate a shared evolutionary ancestry.
Answered by GPT-4o mini
The correct response is:

**DNA sequences**

DNA contains the genetic code that encodes the information necessary for the development, functioning, and reproduction of all known living organisms on Earth.
Answered by GPT-4o mini
Based on the provided amino acid sequences for the hemoglobin alpha protein, the two species that would have a more recent common ancestor in a cladogram are:

**Humans and Chimpanzees**

This is indicated by their similar sequences, as both humans and chimpanzees have the same first four amino acids (Val-Thr-Asp-Leu) compared to the more distinct sequences observed in gorillas and lemurs.
Answered by GPT-4o mini
The correct response is:

**Yes, but only if they are linked to other evidence and patterns.**

Fossils provide important evidence for evolution by showing how organisms have changed over time and allowing scientists to identify relationships among species. However, to fully understand and confirm evolutionary changes, fossil evidence is often considered alongside genetic, embryological, and other types of evidence.
