Answer:
C
Explanation:
The most accepted theory on the Moon's origins, the Giant Impact Hypothesis, proposes that a Mars-sized body known as Theia collided with Earth approximately 4.5 billion years ago. This collision ejected material into Earth's orbit, which then formed the Moon.
The most recent and widely accepted theory about the origins of the Moon, known as the Giant Impact Hypothesis, suggests that approximately 4.5 billion years ago, a protoplanet roughly the size of Mars, known as Theia, collided with the nascent Earth. This violent collision resulted in a massive amount of matter ejecting into the Earth's orbit, eventually coalescing and forming what we now know as the Moon. This theory is supported by several pieces of evidence, such as the similar composition of certain isotopes on both the Earth and Moon and the Moon's low density compared to Earth, which suggests it came from the Earth's outer crust.

More carbon would be released from fossil fuels.
Carbon would build up in the atmosphere.
Animals would perform more photosynthesis.
b. stabilizing selection
c. a mechanism of evolution
d. directional selection
Regular distribution is observed for many organisms due to _______.
a. the need to maximize exposure to sunlight
b. the need to avoid predators
c. interactions between individuals
d. the plentiful availability of water
Natural selection is the differences in survival and reproduction as the consequence of differences in phenotypes. According to Darwin's theory of evolution, natural selection is the only factor that affects a frequency of different variations and it is the only mechanism of evolution.
Q2. The answer is c. interactions between individuals.
Organisms interact with other organisms or abiotic factors in some system. The interaction between individuals affects their regular distribution. For example, if two groups are in competition for resources, to maximize resource utilization, they will probably live in different areas or will defend territory. Also, some symbiotic organisms are expect to be distributed similarly.

The answer is a tumor.
Tumors are characterized by cells that have a mutation in their DNA that causes them to reproduce unregulated hence proliferate and do not form true tissues. Inhibitors, called tumor suppressors, act like a ‘brake’ in the cell cycle. Cyclins, on the other hand, are the ‘gas pedal’ for the cycle. The right balance ensures that cell cycle is well regulated. When the DNA is a cell is damaged, the tumor suppressors are rectruited to stop any further progress of the cell cycle and the cell undergoes apoptosis.
