by the process of uplifting the sedimentary rock
D)
exposing the sedimentary rock to extreme temperature and pressure
Ok
Answer:
D
Explanation:
Those sediments can be formed from the weathering and erosion of preexisting rocks. Sedimentary rocks also include chemical precipitates, the solid materials left behind after a liquid evaporates. Metamorphic rocks form when the minerals in an existing rock are changed by heat or pressure below the surface.

5. Peppered moths vary in darkness. Some have a lighter
coloration and some have a darker coloration. Before the
industrial revolution only 2% of the moth population was
darker in coloration. After the industrial revolution, 95% of
the population showed this darker coloration. Birds eat the
moths they can see on the trees.
Explain how natural selection will occur
The natural selection that occurs at the time when there should be considered as the evolutionary instance.
Arise of natural selection:The evolution of the peppered moth represents the evolutionary instance of directional color that changes in the moth population as it shows the consequence of air pollution at the time of the Industrial Revolution.
In the future date, at the time when the pollution should be decreased so the light-colored form should be predominated again.

Natural selection is when
decides who survives and who doesn't?
Answer:
Nature
Explanation:
Natural selection is when nature decides who survives and who doesn't. Therefore, option A is correct.
What is natural selection?The process through which populations of living things adapt and change is known as natural selection. A population's members are naturally varied, which means that they are all distinctive in some ways. This variety indicates that some people have characteristics that are more environment-appropriate than others.
For instance, giraffes' long necks have allowed them to consume plants that other animals cannot.
Natural selection happens when people with a particular genotype have a higher chance of surviving, reproducing, and passing on their alleles to the following generation than individuals with a different genotype. Hence, option A is correct.

Explanation:
What are the three forces that drive (create and cause to continue) ocean currents?
Answer:
The rise and fall of the tides. Tides create a current in the oceans, which are strongest near the shore, and in bays and estuaries along the coast. ...
Wind. Winds drive currents that are at or near the ocean's surface. ...
Thermohaline circulation.
Explanation:
The three forces that drive (create and cause continuing) ocean currents are wind, water density differences, and tides.
What are ocean currents?Gravity, wind, and water density all contribute to the continuous, predictable, directed movement of seawater known as ocean currents. Water in the ocean can move both horizontally and vertically. Horizontal movements are referred to as currents, while vertical changes are called upwellings or dwellings.
The three main water flows in oceans are waves, tides, and ocean currents. Waves are produced by the wind's effect on the ocean's surface. The temperature difference between the warmer equator and the cooler poles causes ocean currents.
Therefore, the three factors of wind, water density variations, and tides are what drive (make, generate, and sustain) ocean currents.

Why are viruses labeled as parasites/pathogens
Answer:
Parasites are part of a large group of organisms called eukaryotes. Parasites are different from bacteria or viruses because their cells share many features with human cells including a defined nucleus. Parasites are usually larger than bacteria, although some environmentally resistant forms are nearly as small.

what happens to the carbon and oxygen from CO2 after it has been removed from the air by the plant via photosynthesis
Answer:
Plants absorb carbon dioxide from the air and use it to feed themselves in the process called photosynthesis. The carbon dioxide, through tiny pores called stomata, reaches the leaves of the plant. ... The factory emits Oxygen, or O2, into the ambient air until the process is finished.
Explanation:
After the removal of CO2 from air by the plant, then Carbon would be absorbed by plant, Oxygen will be emitted into the air.
Photosynthesis can be regarded as the process which involve the use of sunlight , carbon dioxide and water by plant, so that to oxygen can be created as we as energy in the form of sugar.After the absorption of the CO2 from atmosphere by plant through the stomata, the plant convert it into carbon and oxygen, and the oxygen will be released to the air.Therefore, the process is called Photosynthesis

how do flowering plants reproduce ( secually, asexually, or both
Answer: Flowering plants can reproduce both by sexual and asexual means of reproduction. Sexual reproduction involves the fusion of male and female gametes which takes place through pollination by birds, insects, and water. This pollination causes the fertilization and the female ovules grow into seeds.
Explanation: No need to thank me
Answer: Both, depending on what type of flower the plant is. Some plants reproduce asexually, while other reproduce sexually. Some plants reproduce both ways. Therefore, it depends on the type of flower/plant the flowering plant is.
