A cell begins undergoing mitosis. Which is the key molecule used by the cell to provide energy to the cell to complete mitosis? a. Uranium
b. Adenosine Triphosphate
c. Carbon Dioxide
d. Phosphorus

Helicase is a protein which has the job of “unzipping” the DNA double helix. Because it speeds up this chemical reaction in the
cells, helicase is an example of
a. a carbohydrate
b. an enzyme
c. a simple sugar
d. a lipid

A single gene mutation occurred in a pea plant that caused it to be chlorophyll deficient. This decrease in chlorophyll might lead
to which of the following…
a. decreased ability to absorb light
b. increased ability to absorb light
c. increased ATP production
d. increased glucose production

sheep is a herbivore animal whereas grasshopper belongs to the class chordates but both of them feed on greens.  

if grasshopper and sheep feeding on a pasture land, i do not think both of them will have any impact on each other. however, the number of the species can make difference. since sheep feed on greens, there is a possibility there left no pasture land for the grasshoppers or they may get extinct.

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
