Phycobiliproteins are a complex of accessory pigments and proteins found in cyanobacteria but not in green algae. A researcher c
Ksju [112]

Answer:

Option D

Explanation:

Cyanobacteria preserve its photosynthetic pigments in the thylakoids which allows masking of green of chlorophyll a and other accessory pigment i.e phycobiliproteins (phycocyanin, allophycocyanin and phycoerythrin).  

Chlorophyll a is mainly responsible for harvesting light for photosynthesis. Phycocyanin is blue in color, allophycocyanin is blue in color  and phycoerythrine is red in color. These together harvest light in the green, yellow and orange part of the spectrum which cannot be used by other phytoplankton species

Hence, option D is correct

If there was a fungicide that killed all fungi, make a prediction on how that would affect the ecosystem and eventually us human
marishachu [46]
Fungi is what decomposes things and puts nitrogen back into the ground. without the fungi plants would soon begin to run out of the nutrients they need. lack in vegetation would soon form. animals would then start to die of or migrate to different locations. so eventually you would begin to see less food and more wildlife in town because of the food shortage.

Pluripotent cells can give rise to all of the cell types that make up the body; embryonic stem cells are considered pluripotent. Multipotent cells can develop into more than one cell type, but are more limited than pluripotent cells; adult stem cells and cord blood stem cells are considered multipotent.

Imagine that the climate in your region became extremely arid, and freshwater became a scarce and precious resource. Wasteful us
Ilia_Sergeevich [38]

Answer:

<em>Answer = explanation.</em>

Explanation:

I would try adapting without any problems, since if we suppose that this climate change happened recently, the answer is probably human activity. And, even if I wasn't part of it, there is nothing I can do but tolerate it.

But now, the important part. I would reduce the amount of weekly showers to 1-3 showers a week. I would also buy water only for my consumption, making sure nothing would be wasted. Given that water would be x100 more expensive, I would also buy water-rich fruits and vegetables from the market (and of course, these would have to come from somewhere else, since I would not support illegal watering) such as cucumbers, watermelons, melons, nectarines, etc.

Hope it helped,
