<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>
Derived characteristics refers to those traits that have changed from ancestral form or function. The derived character, which cause K. monera to be divided into K. archeabacteria and K. eubacteria is that genetically and biochemically the two are different. The archeabacterial possess unusual lipid, which is not find in eubacteria or any other organism. And this give it the capacity to live in extreme environments.
It would disrupt the CO2 cycle, since plants would no longer absorb carbon dioxixde, nor let out oxygen meaning it would also provide animals with little oxygen, and they can’t produce CO2 then either
Explanation:
this is the best I can do for you sorry let me know if this helps any.
When a stem cell divides, it first becomes an immature red blood cell, white blood cell, or platelet-producing cell. The immature cell then divides, matures further, and ultimately becomes a mature red blood cell, white blood cell, or platelet.
Answer:
Rock
Explanation:
Minerals are inorganic substances that occur naturally in nature and have a
a definite chemical composition and a crystalline structure while rocks may consists of one or many minerals together along with some organic remains due to which it may not look shiny and crystalline from outside.
Here, the two characteristics that enable the reader to identify the object given by grandmother to Emily as rock are –
a) Looks ugly on the outside (shows the presence of organic matter)
b) solid purple color with pretty crystals (crystalline structure inside)
