Adaptation will mean taking action to minimize the negative effects of change. ... the use of new tools and techniques for decision-making, For example, projected increases in drought, fire, windstorms, and insect and disease outbreaks are expected to result in greater tree mortality. Fewer trees will reduce Canada’s timber supply, which in turn will affect the economic competitiveness of Canada’s forest industry. This would leave forestry-dependent communities vulnerable to job losses, closure of forestry processing facilities and an overall economic slump.
Answer:
a) 25.5°(south of east)
b) 119 s
c) 238 m
Explanation:
solution:
we have river speed 
=2 m/s
velocity of motorboat relative to water is 
=4.2 m/s
so speed will be:
a) 
=+
solving graphically
=4.7 m/s
Ф=
=25.5°(south of east)
b) time to cross the river: t=
=
=119 s
c) d=
=(2)(119)=238 m

Answer:
Contemporary light microscopes are able to magnify objects up to about a thousand times. Since most cells are between 1 and 100 μm in diameter, they can be observed by light microscopy, as can some of the larger subcellular organelles, such as nuclei, chloroplasts, and mitochondria.
A cell is the smallest unit of a living thing. A living thing, whether made of one cell (like bacteria) or many cells (like a human), is called an organism. Thus, cells are the basic building blocks of all organisms.
Cells have many structures inside of them called organelles. These organelles are like the organs in a human and they help the cell stay alive. Each organelle has it's own specific function to help the cell survive. The nucleus of a eukaryotic cell directs the cell's activities and stores DNA.
If the cell grows beyond a certain limit, not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume. When this happens, the cell must divide into smaller cells with favorable surface area/volume ratios, or cease to function.
Explanation:
Explanation:
<h2>
For Copper</h2>
dH copper = mCdT copper
<em>(Specific Heat of copper=0.385 J/g C )
</em>
dH = 500 g (0.385 J/g C) (78 C rise)
dH = 15,015 Joules
<h2>
For Water</h2>
dH water = m C dT water
<em>(Specific Heat of copper=</em>4.184 J/g-C<em>)
</em>
<em />
dH = 400 g (4.184 J/g-C) (78 C rise)
dH = 130,540 Joules
total heat = 15,015 + 130,540 = 145,555 Joules
<h2>
Percentage for Water </h2>
(130,540 Joules / 145,555 Joules) x 100 = 89.7 %
If we consider that we have 3 Significant Figures,
then, the answers become
,
15.0 KJ must be added for Copper
130.5 KJ must be added for Water
and the total of 145 KJ must be added in the kettle with the water
89.7 % of heat goes to the Water
