Answer:
Earliest- gametophyte dominance, sporophyte dependence
Middle- sporophyte dominance, gametophyte independence
Recent- sporophyte dominance, gametophyte dependence
Explanation:
The life cycle of plant alternates between the two phases: the haploid gametophyte which produces gametes and the diploid sporophyte which produces spores. The evolution of land plants shows how these are dependent on each other in terms of the requirement of nutrition.
In bryophytes, the gametophyte is the dominant phase on which the sporophyte depended. Later in pteridophytes, the sporophyte became dominant which is present in the later evolved groups namely the gymnosperms and the angiosperms. The gametophyte was independent on the sporophyte but in angiosperms and gymnosperms, it is dependent.

Explanation:
<span>A drug used to treat CML, imatinib, binds to the active site of Abl kinase. Why does this drug work to treat this type of cancer?
</span><span>B) By binding to the active site, the drug prevents the ability of Abl kinase to bind to its substrate.
</span>
Imatinib works against CML by binding close to the ATP binding site of bcr-abl. The binding results to the<span> locking in of the bcr-abl to a closed or self-inhibited conformation and inhibiting the enzyme activity of the protein </span><span>semi-competitively.</span>
<span>Active and passive transport help to maintain homeostasis because they transport fluid/water/materials across the plasma lemma (cell membrane). All of these materials need to exist in certain ratios for the cell to function properly. </span>
