Ok ok no fret im here to help as best as i can :)
Weathering is a process that breaks down or changes rocks into smaller
pieces. Various atmospheric aspects are responsible for weathering
processes. Weathering is different from erosion. Erosion is the movement
of rock pieces and sediment from one area to another. Weathering is the
breaking down of rocks and erosion is a wearing away of rocks. There
are two main types of weathering: physical (or mechanical) weathering
and chemical weathering. Quite often, both forms of weathering will
occur together
Physical weathering is also known as mechanical weathering. This type of
weathering occurs when rocks and other landforms are broken down by
physical factors in the environment. These physical factors include
wind, water, sun, ice and temperature changes
Answer:
The correct answer is option (d)-"All of these are found in the fossil record and have been used by scientists to understand human evolution".
Explanation:
There is plenty of evidence that supports the proposal of how humans has evolved during past times. The fossil records that scientists has used understand human evolutionary patterns include the following. Ardipithecus ramidus bones that revealed advances in upright walking, even tough they had a small brain that measured between 300 and 350 cm3. Australopithecus lack of an opposable big toe suggest that they lived on the ground instead of in trees. Homo erectus was the first species to use and control fire, as suggested by evidence of microscopic traces of wood ash.
Glycolysis.
In glycolysis, glucose—a six-carbon sugar—undergoes a series of chemical transformations. In the end, it gets converted into two molecules of pyruvate, a three-carbon organic molecule. In these reactions, ATP is made.
Food webs are more complex than food chain
The given blank can be filled with medulla.
The medulla also called the medulla oblongata is the segment of the brainstem that is factually the stem, which elongates from the brain. The medulla is positioned below the pons and above the spinal cord and is a major relay intersection for information conducted to and from the spinal cord and the brain. This section of the brain is a monitoring center for circulation and respiration.
