I believe the answer is a because the were the first organisms to colonize bare rock.
<span>The taiga is an extremely cold area that has constant food shortage and harsh conditions. The lynx does not migrate from the taiga during any period, but rather stay there year round. The lynx is currently waiting to get a place on the endangered species list.
Their habitat is being rapidly destroyed, and many farmers view them as a pest that threatens livestock and other animals that are essential to the farm. Additionally, people hunt the lynx for their fur coats and for their meat.</span>
Answer:
d. centromere
i. mitosis
f. metaphase plate
j. two. NOT SURE about this one
Explanation:
d: sister chromatids joined by a centromere
i: During the mitotic phase, a cell will undergo mitosis to form two new nuclei and then divide to form two new individual cells during cytokinesis.
f. Chromosomes align at the metaphase plate at right angles to the spindle poles. Chromosomes are held at the metaphase plate by the equal forces of the polar fibers pushing on the centromeres of the chromosomes. In anaphase, the paired chromosomes ( sister chromatids) separate and begin moving to opposite ends (poles) of the cell.
Attached is the experiment details. I found the exercise on the internet.
The pigments of the algae, according to the experiment, absorb the most strongly around the violet-blue and red parts of the spectrum and so photosynthesis is the most efficient when the algae are under such wave lengths. The results were that more oxygen-seeking bacteria gathered around the algae that were under such wave length because there were more production of oxygen.
If the pigments were now to absorb most strongly around the 500 nm to 560 nm, the bacteria would gather the most around the algae under such wavelegth (green light).
