Answer 6

Unit 6 lesson 6:

vvvvv

Here are the correct responses for each question based on the scenarios and descriptions provided:

1. **Scenario: An animal is born with a shorter tail, which makes no difference to its ability to survive or reproduce, but by pure luck, the trait is passed down over time.**
- **Answer: Genetic drift**

2. **Process of altering the genome of one species by adding genes from another species.**
- **Answer: Genetic modification**

3. **Scenario: Fish in a murky underground lake develop lighter scales, making them slightly more visible to predators, but they survive long enough to reproduce. A natural event separates the dark-scaled fish from the light-scaled ones, resulting in a new species of dark-scaled fish.**
- **Answer: The fish experienced an evolutionary change because of genetic drift.**

4. **Scenario accurately describing artificial selection:**
- **Answer: A farmer intentionally breeds oranges to be more resistant to aphids.**

5. **Long-term outcomes where an advantageous gene may be shared by every organism of the same species or lead to a new species:**
- **Answer: Evolution**

UNIT 6 LESSON 6!!!!!!

Consider the following scenario:

An animal is born with a shorter tail. This makes no difference to its ability to survive or reproduce, but as a result of pure luck, the animal survives, reproduces, and passes its shorter tail down to its offspring. Over time, the species develops a shorter tail.

What type of process is described in this scenario?

Consider the following scenario:

Some fish in a murky underground lake have lighter scales than the others. This makes it slightly harder for the lighter fish to escape detection by predators, but most light-colored fish live long enough to reproduce. A natural event separates the dark-scaled fish from their light-scaled cousins, and as a result, a new species of dark-scaled fish emerges.

Which statement accurately describes the scenario?

Responses
