The geologists mapped the ocean floor and discovered the mid-oceanic ridge. The correct option is C.
What is crustal movement?The movement of the plates that make up the Earth's crust is referred to as tectonic shift. The Earth is comprised of a many major plates and several minor plates.
The Earth is constantly undergoing change. The Earth's crust, known as the lithosphere, is made up of 15 to 20 moving tectonic plates.
Very active crustal movements in subduction zones, characterized by uplift and erosion in island arcs and subsidence and sedimentation in ocean trenches, continue indefinitely.
The upward movement of hot rocks from deeper parts of the Earth's crust is unavoidable due to uplift and erosion of the Earth's crust.
Geologists discovered the mid-oceanic ridge after mapping the ocean floor.
Crustal movements generate boundaries that are convergent, divergent, and transformative.
Thus, the correct option is C.

Answer:
A. Uses the law of superposition to determine which rock is older or younger.
Explanation:
I majored in Biology
The law of superposition of rocks is used to determine the age of rocks.
A rock is defined as a solid mass of minerals which could be found above or below the earth's surface. Rocks are of different types and they take different forms.
In order to determine the relative age of rocks, the law of superposition is used. This law can be used to determine which rock is older or younger.

Free lime and natural gypsum, in addition to soluble salts, are frequently found in the C horizon. Therefore, option (C) is correct.
What is C Horizon?Free lime and natural gypsum, in addition to soluble salts, are frequently found in the C horizon. Unconsolidated material can be found above bedrock at the C Horizon, which is also referred to as the substratum. It has not undergone enough deterioration to be classified as soil, but it is nevertheless considered to be a layer of a soil profile.
The C horizon is often composed of boulders, cobbles, pebbles, and other types of rocks that have not been worn or have only been lightly weathered. Due to the fact that the layers of soil that are found above the C horizon are typically generated from this material, these rocks are referred to as parent rocks.

From which molecules are mRNA molecules transcribed?
A. tRNA
B. rRNA
C. DNA
D. protein
Answer:
C
Explanation:
mRNA molecules are transcribed from DNA molecules. Therefore, option (C) is correct.
Synthesis of mRNA molecules utilising a DNA template occurs during transcription. RNA polymerase and other transcription factors attach to particular sections of DNA known as promoters in the nucleus of eukaryotic cells. The DNA double helix is subsequently unwound by the RNA polymerase, and using one of the DNA strands as a template, it starts to synthesise a complementary RNA strand.
According to the complementary base pairing principles, the RNA polymerase adds nucleotides to the expanding mRNA strand during transcription. While cytosine (C) pairs with guanine (G), adenine (A) in DNA pairs with uracil (U) in mRNA. The mRNA molecule is released and the DNA double helix reforms once the full gene sequence has been read.

The most important part: the body has to be buried suddenly, which is rare. Rapid burial can happen due to natural effects, including volcanic eruptions, which bury things in ash, or dying near a flooding stream, which rapidly covers the body in sediment.
Explanation:
Water seeps into the remains, and minerals dissolved in the water seep into the spaces within the remains, where they form crystals. These crystallized minerals cause the remains to harden along with the encasing sedimentary rock.

If the objective lenses of a microscope can be changed without losing focus on the specimen, they are said to be ______. A) equifocal. B) totifocal. C) parfocal.D) optifocal.
Answer:
C) parfocal.
Explanation:
A microscope can be defined as an optical device that is typically used to make an enlarged (magnified) image of a minute (small) object and as such reveals all the little information about the object that cannot be seen by the natural human eye.
A microscope is said to be parfocal if its lense is binocular and they can both be in focus.
Hence, if the objective lenses of a microscope can be changed without losing focus on the specimen, they are said to be parfocal.

Which of the following statements is TRUE about fiber? A) Fiber is best obtained through pills and other fiber supplements. B) Consuming excessive fiber can increase C) Increases in daily fiber intake should be gradual.D) The typical american diet provides about 25g fiber a day.
Answer:
C) Increases in daily fiber intake should be gradual.
Explanation:
Fiber is the indigestible part of plants and carbohydrates. Beans, peas and lentils are some sources of fiber.
Fiber is best obtained through dried peas and beans and not from pills and the optimal amount of fiber varies with gender, age and pregnancy so there is no fixed diet for fiber and 25 g fiber a day is recommended for adult women and 38 g for adult men.
Increases in daily fiber intake should be gradual because a high fiber diet helps to prevent diseases like heart diseases, diabetes, constipation, and colon cancer. It also smoothens the digestive system and lowers the cholrestrol.
Hence, the correct answer is "C) Increases in daily fiber intake should be gradual."

Gradual speciation is more likely to be associated with small changes building up in:___________
A. ability to reproduce asexually
B. genes associated with DNA synthesis
C. geographically diverse areas
D. stable environments
Answer:
D. stable environments
Explanation:
In the gradual speciation model, changes in species are slow over time that occur in small steps. Change in speciation rate influences two factors that are environmental conditions and population size.
Gradual speciation mostly occur in large populations that move towards evolution and live in a stable environment. The stable environment provides enough time for the evolution to happen and stable habitat for the new species to grow slowly.
Hence, the correct answer is "D. stable environments".
