The principle of competitive exclusion is best illustrated by which of the following examples?
a. a poisonous salamander is bright yellow and black in color.
b. two species of macaws (large tropical birds, like parrots) found in different locations feed on the same fruit. when these two species are found living in the same geographic region, they feed on two different species of fruit.
c. two species of ant, one large and one small, feed on plant seeds that have a special "pouch" containing a sweet substance that attracts the ants. the ants carry the seeds back to their nests, consuming the sweet substance but leaving the seed intact. seeds of a variety of sizes are used by two ant species. semibalanus and chthamalus barnacles use different spatial locations in the intertidal.
d. two species of grass share the same niche. park rangers plant seeds of both species on a hillside to prevent soil erosion. six months later, only one species of grass is present.

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

answer >   yes we do, women; have three holes, urethral opening(pee hole, vagina, and the women pee/girls pee out of the urethra like the men do; only they have a single opening to pee/ejaculate.   (sorry if i'm too forward with this, but this is for a biology class, isn't it? )

hope that !         : )

the sun creates it's own light, also gives light and life to bunch of stuff like plants,animals,humans etc.photosyntesis is the process of making food which needs sun,water,nutrients etc.

they use sunlight, water, and carbon dioxide to make sugars - c.
