Natural selection is the process by which species adapt to their environment. Natural selection leads to evolutionary change when individuals with certain characteristics have a greater survival or reproductive rate than other individuals in a population and pass on these inheritable genetic characteristics to their offspring. Simply put, natural selection is a consistent difference in survival and reproduction between different genotypes, or even different genes, in what we could call reproductive success. [A genotype is a group of organisms sharing a specific genetic makeup.]
Eliminate
B) Differentiated cells have fewer gene sequences that pluripotent cells and can only produce limited numbers of proteins.
C) Pluripotent cells recruit molecules from nearby cells to increase gene expression while differentiated cells use only internal transcription factors.
D) Differentiated cells and pluripotent cells have different types of activator or repressor proteins present that positively and negatively regulate gene expression in the cell.

relative amounts of reactants and products
Answer:
skeleton equation
Explanation:
Skeleton equations or unbalanced equations are mostly used in chemistry. In a skeleton equation you put chemical formulas in place of chemical names. A skeleton equation doesn’t show the relative and balanced amounts of reactants and products. It’s regarded as a step to writing a complete chemical equation.

Curiousity-A scientist shows interest and pays particular attentions to objects or events. He asks questions and seeks answers.
Honesty-A scientist gives a truthful report of observations. He does not withhold important information just to please himself or others.
Open-Mindedness- A scientist listens to and respects the ideas of others. He accepts criticism and changes his mind if reliable evidence contrdicts his believes.
Skepticism- A scientist bases suggestions and conclusions on evidences. When in doubt, he questions the veracity of a statement in relation to the evidences presented.

2.composite cone volcanoes
3.shield volcanoes
4.pyroclastic volcanoes
Answer:
Shield volcanoes.
Explanation:
Hawaiian volcanoes are the types of vulcanos known as shield vulcanos. Their shape is slightly dome, it is like an inverted shield. They are located in a big area and they don’t have explosive eruptions. This type of vulcanos is created when magma enters the fracture of the stone. One of the most famous volcanos of this type is Mauna Loa in Hawaii.
