What role does hot ion-rich water play in the process of metamorphism?

1 answer:

8 0

Water flows downhill, eroding the host rock to make it smooth. Water cleanses the ironbearing minerals, which helps to delineate the crystal faces. Water boils the rocks that it comes in contact with, causing them to liquefy and slowly cool and harden into a new, stable state. Water interferes with mineral crystallization, thereby delaying the process of metamorphism. Water migrates into host rock carrying ions to stable minerals in order to facilitate growth of new metamorphic minerals.

How can a robin have a ddt concentration of 444 ppm even though the soil contains only 10 ppm of ddt

zaharov [31]

Robin can have a ddt concentration of 444ppm while the ddt concentration of soil is 10 ppm. This happens due to biological magnification.

Explanation:

In biological magnification the concentration of toxic substances at successive trophic levels keeps increasing. Due to biomagnification, what starts out as a small concentration grows while moving to successive trophic levels. DDT is a pesticide which is used to kill pests that affect crops.

DDT used in farms gets deposited in the soil. From the soil it can reach various trophic levels. At each trophic level its concentration keeps increasing.

Robin is a bird that is a secondary consumer and thus belongs to the higher trophic level. Thus even if the DDT concentration is as low as 10ppm in the soil its concentration will keep increasing and can become a high value like 444ppm.

antiseptic1488 [7]

Answer:

50% of getting A blood type

Explanation:

Using a punnet square you have (sorry cant do a square)

IA IB

IA

i

Then you you add all the possible combinations from both parents genes

IA IB

IA IA IA IA IB

i IA i IB i

You now have a 50% chance of A type blood because the lowercase (i) wont change the blood type outcome because the IA over shines it.
