Here are the answers to your questions:
**Question 1: Which statements are true about the Milky Way Galaxy?**
- **The Milky Way is a spiral galaxy.** (True)
- **The Milky Way has arms that spiral around a bright nucleus of stars.** (True)
(Note: The statement "The Milky Way contains no more than 100 million stars" is false, as the Milky Way is estimated to contain **100 billion to 400 billion stars**. The statement "The Milky Way is an irregular galaxy" is also false, as it is classified as a spiral galaxy.)
---
**Question 2: Which type of galaxy is usually made of mostly older stars?**
- **elliptical** (True)
(Elliptical galaxies typically consist of older stars and show little to no ongoing star formation.)
---
**Question 3: What makes up baryonic matter?**
- **ordinary atoms** (True)
(Baryonic matter is made up of ordinary matter, which includes protons, neutrons, and electrons; essentially the atoms that make up stars, planets, and living organisms.)
---
**Question 4: Which type of galaxy is egg-shaped?**
- **an elliptical galaxy** (True)
(Elliptical galaxies have a more rounded or egg-like shape compared to spiral galaxies, which have well-defined arms.)
---
**Question 5: How can scientists detect dark energy using evidence?**
- **Scientists can see the bending of light due to the gravitational force of matter that cannot otherwise be detected.** (True)
(This is related to gravitational lensing, where the effect of dark matter (and to some extent dark energy) can be inferred from the bending of light around massive objects. However, it's more indirect evidence for dark matter than dark energy itself, but it is the closest option regarding evidence supported by observations.)
