Naturalist jean-baptiste lamarck promoted the theory of "inheritance of acquired characteristics". this theory stated that changes developed over the course of the life of an organism would be transmitted to the next generation. a famous example involves a blacksmith. working with heavy hammers, pounding iron all day, blacksmiths developed larger arms than average men. this trait, large and muscular arms, would then be passed down to the children of the blacksmith.

charles darwin developed a competing theory based on variation and a process he called "natural selection". his theory stressed how the differences among the individuals in a population would lead to different rates of survival and reproduction. through this process, in conjunction with what he called a "strong principle of inheritance", entire populations could adapt, and ultimately, evolve.

the fact that many blacksmith apprentices were not born to blacksmith fathers, and they still developed large arms, would have what impact on lamarck's theory?

sea breeze

explanation:

cool air is going towards land allowing for the land to be cooler, the hotter air gets pushed away from the land.

interphase

the period of cell growth when the cell synthesizes new molecules and organelles. the cell is not dividing and it constitutes the majority of the time spent in the cell cycle

prophase

changes occur in the nucleus and cytoplasm. the chromatin condenses to form structures (sister chromatids) visible with a light microscope and the mitotic spindle begins to form, but the nucleus is still in tact

prometaphase

the nuclear envelope fragments and the spindle microtubules attach to the kinetochores of the sister chromatids

metaphase

all the cell's duplicated chromosomes are lined up at an imaginary plane equidistant between the poles of the mitotic spindle

anaphase

begins when sister chromatids separate from each other and ending when a complete set of daughter chromosomes arrives at each of the two poles of the cell

telophase

the daughter nuclei form at the two poles of a cell

cytokinesis

the division of a cytoplasm to form two separate daughter cells. usually occurs during telophase during mitosis. this and mitosis make up to mitotic (m) phase of the cell cycle
