Answer:Harmful or beneficial mutations do influence an organism's survival. This is where natural selection comes into play. ... This is how organisms evolve and adapt to changing environmental conditions over time.
Explanation:
Answer: The environment affects natural selection. Speices need to adapt to changes in environmet. The weaker organisms which fail to adapt to environment perish while the stronger ones who adapt to the environment survive. This is how environment affects natural selection.
Answer:
Ammonites, , Brachiopod, Grapolithina,Trilobites and Nanofossils are examples of index fossils
Explanation:
Ammonites were common during the Mesozoic Era (245 to 65 mya), but were not found after the Cretaceous period. They went extinct during the K-T extinction (65 mya)
Brachiopods which are mollusk-like marine animals appeared during the Cambrian (540 to 500 mya). Some types of them still survive
Grapolithina which are widespread colonial marine hemichordates that also lived during the Cambrian period.
Nanofossils are microscopic fossils which are remains of calcareous nannoplankton, coccolithophores from various eras
Trilobites were common during the Paleozoic Era (540 to 245 mya); about half of the Paleozoic fossils are Trilobites. Trilobites evolved at the beginning of the Paleozoic Era and went extinct somewhere in the late Permian period which was 248 million years ago
This might be extra information but i hope it helps
melting and cooling
B.
plants or animals becoming trapped between layers of sediment
C.
compaction and cementation of sediment
D.
weathering and erosion
The processes which turn a sediment into a sedimentary rock are compaction and cementation of sediment.
Sedimentary rocks are formed by the agglomeration of sediments to form a large mass. These sediments are composed of the remains of plants and animals. As a result of this, sedimentary rocks a re useful in analyzing fossil records.
Sediments agglomerate to form sedimentary rocks under pressure via the process of compaction and cementation of sediment.

The answer is C. Compaction and cementation of sediment, because sediment is powder, when something becomes cemented, it comes together, like cement, when you add cement to water.

D. Neither Technician A nor B
p.s "both"is wrong
Answer:
C. Only tech A is correct
Explanation:
Oil control rings are designed differently than compression rings. A typical oil control ring consists of three separate pieces: two very thin metal rings called scrapers, and a spacer ring called an expander placed in the groove between them.
Answer:
Providing a controlled source of water vapour through which water can be vaporized into the plant envoirment.
Explanation:
Humidity ratio is the ratio of the mass of water in air to the mass of dry air. Humidity is needed in some conditions where the air is very dry. In a very dry air setting, there can be excess moisture loss from the plant surface, increasing the Humidity ratio can counter this effects and reduce excess moisture loss.
