It’s obvious to anyone who visits an American supermarket in winter — past displays brimming with Chilean grapes, Mexican berries and Vietnamese dragon fruit — that foreign farms supply much of our produce.
Imports have increased steadily for decades, but the extent of the change may be surprising: More than half of the fresh fruit and almost a third of the fresh vegetables Americans buy now come from other countries.
Although local, seasonal and farm-to-table are watchwords for many consumers, globalization has triumphed in the produce aisle. And despite the protectionist “America First” message coming from the Trump administration, the growth in imports appears likely to continue.
So this is an apt moment to examine how the shift happened, and what it portends — good or ill — for American consumers and farmers.
“I had no idea that more than half our fruit is imported, and it shocks me that this has happened so quickly,” said Michael Pollan, a professor of journalism at the University of California, Berkeley, whose best-selling books have analyzed the tensions between local and global food systems
Explanation:
Well protists quite very as organisms i.e it is hard to say if an organism is a protist. Some main features of protists are that they have
1. A membrane enclosed nucleus
2.They are mainly single celled
Also protista are found mainly anywhere water is present for example damp soil, pools and lakes.
Hope this helps :).
An atom typically has a neutral charge, as in most cases an atom has the same amount of positively charged protons as it does negatively charged electrons.
Atoms that do not have the same amount of electrons as protons are known as isotopes.

Explanation:
The question assumes heat is not lost to the surroundings, therefore
heat emitted from hotter sample ( 
)= heat absorbed by the less hotter sample( 
)
The relationship between heat (q), mass (m) and temperature (t) is 
where c is specific heat capacity, 
temperature change.
= 
equating both heat emitted and absorb
where the values with subset 1 are the values of the hotter sample of water and the values with subset 2 are the values of the less hot sample of water.
C will cancel out since both are water and they have the same specific heat capacity.
so we have
where m1 = 50g, t 1initial = 330, m2 = 30g, t2 initial = 280,t final (final temperature of the mixture) = ?
-50 * (
- 330) = 30 * ( - 280)
-50 + 16500 = 30 - 8400
80 = 16500+8400
80 = 24900
= 24900/80 = 311.25k
The disease can slow the predator down and the prey can get away easily.
