<span>1. </span><span>Two ways that man can reduce the global
warming is by reducing carbon dioxide (a greenhouse gas) emissions. One way is
by planting more trees. Forests are reservoirs for carbon since their remove
carbon dioxide from the atmosphere in the process of photosynthesis. Second is
by reducing the use of fossil fuels to produce energy. Fossil fuels are the biggest emitter
of carbon dioxide in their combustion</span>
<span>2. </span>Greenhouse<span> gases permit infrared rays from the sun
to pass through them but do not allow heat to escape into the atmosphere. When infrared hits the earth's surface
it turns to the heat wave that has much longer wavelengths. This causes the earth’s atmosphere to retain more heat hence
increased global temperatures.</span>
<span>3. </span><span>When greenhouse gases especially carbon dioxide are reduced in the
atmosphere, the earth is able to radiate more sunlight back into space due to the reduced greenhouse effect. This
enables the global temperatures to remain low. At the poles where temperatures are cold remains
even colder hence the waters in these regions turn to glaciers. The ice continents increase in size and hence a big characteristic
of ice ages. </span>
<span>4. </span><span>Humans are not responsible for global warming even though they contribute but in minimal proportions
as compared to the natural process. This is because
it is estimated that termites produce even more carbon dioxide than humans. Ice
ages and global warming are therefore natural
cycles governed by the sun. However,
human activity aggravates global warming. </span>

<span>The brain is a very complex organ in humans. Although we still have a lot to learn about it, decades of studies in both living and dead humans had revealed that the brain is crosswired, meaning the right side of the brain controls the left side of the body and viceversa. It’s also the part of the brain associated with arts and our creativity. Therefore the answer is B</span>
When the cardiac muscle cell is at rest, the concentration of sodium and calcium is greater on the outside of the cell.
The resting membrane potential (the cardiac muscle cell is at rest) is characterized by more negatively charged inside of the membrane comparing to the outside. The main ions found outside the cell at rest are: sodium (Na+), and chloride (Cl−), and Ca2+ whereas inside the cell it is mainly potassium (K+).
