Vertebrate embryos all follow a very similar developmental process. Which statement could explain this similarity?(1 point)

Question

Responses

All vertebrates require the same nutrients during embryological development.
All vertebrates require the same nutrients during embryological development.

All vertebrates live in similar environments which require the same adaptations.
All vertebrates live in similar environments which require the same adaptations.

All vertebrates inherit the same sequence of DNA from their parents.
All vertebrates inherit the same sequence of DNA from their parents.

All vertebrates develop a backbone that protects the spinal cord.
All vertebrates develop a backbone that protects the spinal cord.

Answer 1

The statement that best explains the similarity in the developmental processes of vertebrate embryos is:

All vertebrates inherit the same sequence of DNA from their parents.

This is because the similarities in embryonic development are largely driven by conserved genetic material and the fundamental processes regulated by genes shared across vertebrate species. While environmental factors and specific adaptations may play a role, the common genetic framework is the primary reason for the similarity in development.

Answer 3

The term for the remains, imprints, or traces of living things from a previous geological age is fossils.

Answer 4

Some mutations, or changes in the sequence of DNA, do not have any effect on the characteristics of the organism. Why is this?(1 point)
Responses

The cell recognizes mutations and ignores them when expressing the gene.
The cell recognizes mutations and ignores them when expressing the gene.

The immune system repairs the mutated sequence during development.
The immune system repairs the mutated sequence during development.

The mutated sequence still codes for the same amino acid.
The mutated sequence still codes for the same amino acid.

The protein built from this mutated sequence is deactivated by the cell.
The protein built from this mutated sequence is deactivated by the cell.

Answer 5

The correct response is:

The mutated sequence still codes for the same amino acid.

This is due to the redundancy in the genetic code, where multiple codons can code for the same amino acid. In such cases, a mutation may not alter the resulting protein or the characteristics of the organism.

Answer 6

What is typically studied when analyzing not-yet-born (or unhatched) animals?(1 point)
Responses

embryological development

DNA sequencing

Answer 7

The correct response is:

embryological development.

When analyzing not-yet-born (or unhatched) animals, researchers typically study embryological development to understand how the organisms form and differentiate over time.

Answer 8

What can scientists analyze to get a better understanding of how plants and animals evolved from a common ancestor?(1 point)
Responses

petrified bones and imprints of plants

Answer 9

The correct response is:

DNA.

By analyzing DNA, scientists can gain insights into the genetic similarities and differences among species, which helps in understanding how plants and animals evolved from a common ancestor.

Answer 10

How can embryos help scientists understand evolution?(1 point)
Responses

Embryos provide evidence for which life forms existed at the same time.
Embryos provide evidence for which life forms existed at the same time.

Embryos contain the code for all life on Earth.
Embryos contain the code for all life on Earth.

Embryos go through various stages that suggest the animal’s evolutionary process.
Embryos go through various stages that suggest the animal’s evolutionary process.

Embryos are frequently fossilized and illustrate change over time.

Answer 11

The correct response is:

Embryos go through various stages that suggest the animal’s evolutionary process.

Studying embryonic development can reveal similarities between different species, providing insights into their evolutionary relationships and common ancestry.
