Climate change is the website which most likely provides reliable information about climate change. Thus, the correct option is C.

Climate change refers to the long-term change in temperatures and weather patterns of the area. These changes in temperature may be natural, however since the 1800s, human activities have been the major driver of climate change, primarily due to the burning of fossil fuels like combustion of coal, oil, and gas, which produces heat-trapping gases that cause global warming.

The Intergovernmental Panel on Climate Change (IPCC) assesses the peer-reviewed literature on the climate change for every 5 to 6 years. Their assessment reports, which are also peer-reviewed, are a credible source of information for the climate change.

Therefore, the correct option is C.

The piece of evidence that Alfred Wegener's original theory of continental drift has access to is the mountains in North America appearing to match up with mountains in Northern Europe. Thus, the correct option for this question is D.

Continental drift may be defined as a type of hypothesis that represents a gradual movement of the Earth's continents over geologic time relative to each other. This movement of the Earth's continents results from the motion of tectonic plates.

According to Alfred Wegener's original theory of continental drift, the continents of the Earth have been adjoined together and have migrated away from each other at different times in the history of the Earth.

This reflects that mountains in the continent of North America appear to match up with the mountains in the continent of Northern Europe.

Therefore,  the correct option for this question is D.

The choice that is involved in both sexual and asexual reproduction is the spores that are in the third option, as the others are involved in sexual reproduction, such as the sperm, egg, etc.

Both types of reproduction have advantages, for example, if a mutation occurs and becomes genetic, the chance of getting the disease is lower in sexual reproduction than in asexual reproduction. The possibility of recombination and crossing over reduces the rate of genetic disorders in sexual reproduction, whereas in asexual reproduction, the mutation passes from one to the other.

Hence, the choice that is involved in both sexual and asexual reproduction is the spores that are in the third option, as the others are involved in sexual reproduction, such as the sperm, egg, etc.

Answer:Plants have adaptations to help them survive (live and grow) in different areas. Adaptations are special features that allow a plant or animal to live in a particular place or habitat. These adaptations might make it very difficult for the plant to survive in a different place. This explains why certain plants are found in one area, but not in another. For example, you wouldn't see a cactus living in the Arctic. Nor would you see lots of really tall trees living in grasslands.

Explanation:

Answer:

These plants grow in very difficult environments. So, researching their genes may help botanists working in agricultural areas develop crops that can grow in inhospitable areas. Also, understanding how these plants survive in harsh conditions may help conservation scientists protect plants if their environments change.

100% percentage of the quartz in the model you chose in the previous question is COMPLETELY LOST, and never becomes part of rock again.

Quartz is a hard, crystalline mineral composed of silica. The atoms are linked in a continuous framework of SiO₄ silicon-oxygen tetrahedra, with each oxygen being shared between two tetrahedra, giving an overall chemical formula of SiO₂.

Quartz is a major component of many types of rock. Quartz is abundant in certain igneous rocks. It forms the clear to grey or even white lumpy blobs in granite and comprise most of silicate-rich or felsic igneous rocks.

Rock crystal quartz is found widely distributed, some of the more notable localities being: the Alps; Minas Gerais, Brazil; Madagascar; and Japan.
