Select the correct answer from the list. The ______________ of dark matter causes baryonic gas and dust to __________________.
The GRAVITY of dark matter causes baryonic gas and dust to CLUMP TOGETHER.
Select the correct answer from the list:
A. Gravity, clump together
B. Electromagnetism, repel each other
C. Strong nuclear force, merge into stars
D. Weak nuclear force, disintegrate
The correct answer is A. Gravity, clump together.
To select the correct answer, let's first understand the question. It seems to have a missing word that should describe the interaction between dark matter and baryonic gas and dust.
To find this missing word, we can approach this in two steps:
Step 1: Understand dark matter's interaction with baryonic gas and dust.
Dark matter is believed to interact with baryonic matter (which includes gas and dust) through gravity. It exerts gravitational forces on baryonic matter, influencing its behavior.
Step 2: Identify the word that fits in the given context.
Given that dark matter's gravitational forces affect the behavior of baryonic gas and dust, we can conclude that the missing word should represent gravitational interaction. Thus, the correct answer would be:
The GRAVITY of dark matter causes baryonic gas and dust to INTERACT.
Using this logic, we can determine that "gravity" is the missing word to fill in the first blank, and "interact" is the missing word to fill in the second blank.
