<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>
Answer:
Translation will not occur.
Explanation:
The start codon is responsible for the initiation of translation in both prokaryotes and eukaryotes. AUG is the start codon in both which code for methionine in eukaryotes and formyl methionine and prokaryotes.
Therefore if the starts codon becomes mutated than the tRNA would not able to recognize the initiation codon and no methionine would be added as the first amino acid so the translation process might not start and no protein forms. Then the ribosome scans further for the next start codon to start translation.
The correct options are as follows:
1. USE, B.
Land use refers to the function of a particular land, that is, what the land is been used for. For instance land can be used for agriculture, construction of roads, residential apartments, hotels, zoos, etc. Land use differs in the urban and rural settings. In the rural settings, land is usually used for farming and forestry while in the urban setting, land is usually used for construction purposes.
2. LUC, OPTION B.
The modification of the earth's surface due to land use is called LAND USE CHANGE, LUC. A lot of changes occur when man use lands for different purposes. For instance, examples of land use change include: reduction in forest biomass, conversion of forest and grassland to pasture, etc,
