Answer:
Layer D
Explanation:
The rock layer with remains of organisms least similar to present day form can be found in Layer D.
Since layer D is the oldest layer, it will contain the oldest fossil in the undisturbed sequence.
This is because of the principle of fossils and fauna succession.
The principle states that "fossils and fauna succeed on another in a definite order".
- Therefore, the oldest rock layer should contain the oldest fossil which is layer D.
- Layer A is the youngest layer and its fossils will be very similar to those of present day.
- So, the older a rock layer, the more farther it will be in resemblance to present day organisms.
Option D which denotes layer D is the right choice.

Answer:
✓The type of sediment on the seafloor.
✓The type of rock on the seafloor.
✓The rate of sediment deposition.
Explanation:
Sea drilling cores are one way to get samples that can be used for analysis whereby some information such as type of sediment on the seafloor and type of rock on the seafloor can be known. Surface samplers can be collected from sediment at very top layers or inside deep of the ocean floor. These samples could have animals hidden, , water and some particles that can be analysed in the muddy deep, devices such as Coring devices can be used in collection of cores. The information that can be determined directly by analyzing seafloor drill cores are;
✓The type of sediment on the seafloor.
✓The type of rock on the seafloor.
✓The rate of sediment deposition.

Answer:
I don't think it was because your room wasn't clean. The main cause of bed bugs is travel, which means most likely you got one on you when you went outside or something, and you accidentally got it into your room. Bed bugs hitchhike on luggage, clothing, people, etc.
If there are blood stains or dark/rusty spots on your bed/pillow, there are definitely bed bugs. The bloodstains/spots come from you crushing the bed bugs accidentally. The place where bed bugs are (in this case, your room), may also begin to smell bad. You might also see eggs laid by the bed bugs.
Let me know if you have any other questions. Good luck!
