Answer:
"Scientists are not close to knowing the exact processes that took place on the earth which led to the origins of life. They may never know the exact answer because the evidence for this very primitive life has probably been destroyed by the more efficient life which evolved from it.
Explanation:
The birds with the beaks most suited towards digging and grasping. If they find their food deep underground, the beak would need to be able to push through the dirt and be able to keep the worm in it for consumption.
These organelles group together to eventually form cells, or the basic units of all living things.
Organelles are specialized structures in the cytoplasm of cells which provide essential cell functions and are composed of different molecules (macromolecules). Cells as the smallest basic units of life are then grouped in tissues (similar cells which provide a specific function), layers of different tissues work together to provide specific function and form organ, organ group in organ systems which then compose the whole organism.
D. To see the outside world
Most metamorphic processes take place B. a few kilometers below Earth’s surface.
<h3>Further explanation
</h3>
Metamorphism is the change of minerals or geologic texture in pre-existing rocks without the protolith melting into liquid magma. Metamorphism often occurs on two scales: contact and regional. Contact metamorphism occurs locally in areas adjacent to igneous intrusions or in areas that are in contact with hot water known as hydrothermal fluids. Whereas regional metamorphism occurs over much larger areas such as rising mountain ranges, large igneous intrusions can form and warp overlying strata increasing the pressures above the intrusion. Regional metamorphism usually produces foliated rocks such as gneiss and schist.
There are other ways that metamorphic rocks can form, Dynamic metamorphism. Dynamic Metamorphism also occurs because of mountain-building. The huge forces of heat and pressure cause the rocks to be bent, folded, crushed, flattened, and sheared.
Metamorphic rocks form when increased heat and pressure force physical changes in the crystalline structure of an existing rock. Under the right conditions, any type of rock can become a metamorphic rock including igneous rocks, sedimentary rocks, and even other metamorphic rocks. Therefore metamorphic processes result due to intense heat and high pressure below the Earth's surface.
