The preservation of ancestor species is important for human welfare for several reasons. One reason is that these species may contain important genetic material that can be used to develop new crop varieties with desirable traits, such as disease resistance or increased yield.
For example, the Mexican teosinte is considered the ancestor of modern corn, and its genetic material has been used to develop new corn varieties with increased resistance to pests and environmental stresses.
Preserving ancestor species is also important for maintaining the biodiversity of the planet. Biodiversity is important because it provides ecosystem services, such as air and water purification, nutrient cycling, and carbon sequestration, that are critical for human survival and well-being. Additionally, biodiversity is important for cultural and aesthetic reasons, as many people value the natural world for its beauty and intrinsic worth.

The answer is crossing over, or B
Answer:
Carbon's unique property of tetravalency enables it to form strong covalent bonds with up to four other atoms, including other carbon atoms. This allows carbon to create long chains and intricate rings in molecules, giving rise to the diverse and complex organic compounds found in nature. These structures are the basis for the vast array of organic compounds essential to life on Earth.
Before forming a hypothesis, an individual firstly makes an observation and formulates a question. Conducting some research follows, which aids in the formation of a hypothesis. A hypothesis, which is an educated guess, predicts the outcome of a situation.
The steps leading up to the formation of a hypothesis typically involve first making an observation about the natural world. This could include noting a trend, pattern or single event. From this observation, questions might arise that the observer seeks to answer. Following observation and question formulation, the next step is often to conduct some research about the topic which can inform the creation of a hypothesis. A hypothesis is a testable statement that predicts the outcome of a situation given certain conditions, often presented in an "If... then..." format. It serves as an educated guess to explain the initial observation.
