The genetic code is carried by the DNA molecule in most organisms. DNA is the store for hereditary information.
In eukaryotic cells, DNA is found in the cell nucleus, while in prokaryotes it is found in the nucleosome.
The genetic code is the triplets of nucleotides in DNA and RNA that define and direct which amino acid is used in protein synthesis.
The genetic code is expressed in 64 different triplet combinations that code for different amino acids. Three of these triplets are called non sense triplets or codons because they do not code for any amino acid. The rest are sense codons.
An important part of photosynthesis is light thus the answer would be : <span>Sunlight provide light energy that allow photosynthesis to occur in plankton and aquatic plants.</span>
<span>The correct answer would be C. The adrenal glands, which are also known as suprarenal glands, are glands that belong to the endocrine system. Adrenal gland produces the steroids aldosterone and cortisol and various hormones including adrenaline which help in the response of an individual to stress. They are found above the kidneys. Each of the gland has an inner medulla and an outer cortex which produces steroid hormones. The adrenal cortex has three zones which are zona glomerulosa, the zona fasciculata and the zona reticularis.</span>
<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>
I think the correct answer from the choices listed above is option C. The result of the dissociation of water is the formation <span>of H- and OH+ ions. This process is reversible which means that it could form back to water. Hope this answers the question. Have a nice day.</span>
