What is meant by Dark matter?Dark matter may be defined as the type of particles that do not absorb, reflect, or emit light significantly. Due to this, they cannot be exposed by visualizing electromagnetic radiation. The materials of dark matter can not be examined directly.
According to the context of this question, dark particles considerably include weakly interacting massive particles along with the part of black holes and massive compact halo objects. Hypothetically, it is believed that approximately 85% of the matter in the universe accounts for dark matter.
Therefore, the correct options for this question are A, B, and D.

In which type of fault is the hanging wall above the footwall?
normal
reverse
strike-slip
horizontal
Answer:
B. Reverse
Explanation:
Got it right on edgeA hanging wall and footwall are present in every fault that is inclined from vertical. In reverse type of fault is the hanging wall above the footwall. Therefore, option B is correct.
What is footwall ?The higher or overlaying block along the fault plane is referred to as the hanging wall, or headwall, and the block below is referred to as the footwall as rocks slide past one another during faulting. The direction in which the fault plane and Earth's surface collide is known as the fault strike.
The rock above the fault zone in a cross-section view of a fault is referred to as the hanging wall.The foot wall refers to the rock beneath the fault zone.
Consider digging a mine along the fault line to help you distinguish between the two. The footwall is the brick directly beneath your feet, and it is also the one on which you would hang your miner's lantern.
Thus, option B is correct.

Answer:
All prokaryotes have plasma membranes, cytoplasm, ribosomes, a cell wall, DNA, and lack membrane-bound organelles.
Which of the following would contain the largest concentration of digestive enzymes?
cell membrane
ribosome
chloroplast
lysosome
The LYSOSOME contains the largest concentration of digestive enzymes. This organelle has an internal acidic pH required for these enzymes to carry out their functions.
The lysosome is a eukaryotic membrane-bound organelle that contains different types of hydrolytic enzymes to degrade cellular components.
This organelle (lysosome) is part of the endomembrane system, which also includes the endoplasmic reticulum, Golgi apparatus, transport vesicles and nuclear envelope.
The main functions of the lysosomal enzymes include degradation and recycling of cellular byproducts, and metabolic roles.
