<u>Answer:</u>
<em>The genetic instructions are found in </em><u><em>the nitrogen bases </em></u><em>within the DNA, which is contained in </em><u><em>nucleotide</em></u><em> inside the nucleus of the cells. </em>
<u>Explanation:</u>
Inside nucleotide there are nitrogen bases along with phosphate group and sugar group. The four nitrogen bases are <em>adenine, thymine, guanine and cytosine (ATGC). </em>
These four bases pair up with each other inside the nucleotide. The order in which these bases are placed determines the genetic codes. This passes the instructions and characteristics from the parents to offspring.
Answer:
Genetic
Explanation:
because of the genes being passed
<span>The ways for lessening the effect of increased carbon include reducing the components of the carbon footprint (the amount of carbon dioxide and other carbon compounds emitted due to the consumption of fossil fuels).</span> Air travel is one of the main components of the carbon footprint. <span>The solution for reducing the amount of carbon dioxide in the air is to burn fewer fossil fuels, but it is very difficult because the burning of fossil fuels is necessary for heating, electricity generation and transport.</span>
Power stations that burn fossil fuels to produce electricity are one of the main contributors of carbon dioxide in the atmosphere and the way to reduce it is to use less electricity which can be done by turning down the heating at home, insulating home, <span>using low-energy lamps etc.</span>
Answer:
The duplication of a cluster of four Hox genes is equally likely as the duplication of a single Hox gene.
Explanation:
This comes from the definition of the parsimony principle, which is the action of choosing the simplest scientific explanation fitting the given evidence, meaning that all other elements are equal when evaluating the hypothesis. In biology the best hypothesis is the one that requires the fewest evolutionary changes.
Since three independent duplications of an individual Hox gene is in evolutionary terms, more complex than a single duplication or a cluster, then that hypothesis would be the most parsimonious.
