A). Calculation: Given mass of Au * 1mol of Au/molar mass of Au= # of moles
;
57.01 g Au*1 mole of Au/196.97g Au=0.3 moles of Au. So the answer is 0.3 moles of gold(Au). Good luck on the rest, and message me on Brainly if you need more help. I'll be happy to.
The asthenosphere and outer core would solidify.
The snakehead could unreservedly eat little fish and scavangers, so that would evacuate/diminish the predator for zooplankton and phytoplankton. So zooplankton and phytoplankton populace would increment while little fish and scavanger populace would diminish. Presently if little fish and shellfish populace diminishes, their predators would have bring down sustenance, so vast fish pop. would diminish. On the off chance that vast fish pop. diminishes, their predators will have less nourishment thus the number of inhabitants in well evolved creatures will somewhat drop, however not by much, since they can feast upon zooplankton.
So at last, just the phytoplankton populace would increment while everything else diminishes.
Answer:
In both groups, sperm swim from antheridia to archegonia
Explanation:
Bryophytes are the plant group that does not have a vascular system. These plants do not produce seeds. Ferns and horsetails are seedless vascular plants. These plants have vascular tissues (xylem and phloem) to serve in the conduction of water, minerals, and sugars from the one plant part to the other. But these plants do not produce seeds and hence, are seedless vascular plants.
Both bryophytes and the seedless vascular plants depend on water for fertilization. These plants release their male gametes in water which in turn move towards the female gamete. Sperms, the male gametes of these plants swim in the water to reach the female gamete.
Antheridium is the male gametangium that serves as a site for the production of male gametes while archegonia are the female gametangia where the egg cell is produced.
Some common adaptation in organisms would be:
Behavioral adaptation.
Biological adaptation.
Natural selection.
