Answer: Mutation can affect an organism by resulting to a change in the number and structure of chromosomes (chromosomal mutation). A typical example of this type of mutation is Down's syndrome where the individual contains 47 instead of 46 chromosomes.
Mutation can also result to a change in the nucleotide sequence of the DNA molecule in a particular region of a chromosome(Gene mutation) an example of genetic mutation is sickle cell anemia

Answer:
i)declination of resources
<em>ii</em><em>)</em><em> </em><em>air</em><em>,</em><em> </em><em>water</em><em> </em><em>and</em><em> </em><em>land</em><em> </em><em>pollution</em>
<em>iii</em><em>)</em><em> </em><em>global</em><em> </em><em>warming</em>
Explanation:
As we all know that population is increasing day by day, all the country of the world are facing rapid population growth.we are facing many problems, the population growth is increasing day by day, the more the population, the more resources we need due to this, the resources is decreasing day by day, we need more resources as there is more population, the increasing population makes more pollution due to this global warming is increasing. <em>We know that there is no more more resources in our world if the resources is finished in this day the future generation will not be able to survive and will not be able to use such resources</em><em>.</em><em>we should prevent such resources for future generation also the future generation </em><em>should</em><em> get the chance to use such resources </em><em>.</em><em>the pollution is increasing day by day </em><em>.</em><em>we should control it </em><em>.</em><em>the main thing is that we should control the rapid population growth </em><em>population</em><em> </em><em>growth should be controlled due to this </em><em>global</em><em> </em><em>warming</em><em> </em><em>is</em><em> </em><em>increasing which is very dangerous </em><em>leading</em><em> </em><em>to the declination of ozone layer due to </em><em>which</em><em> </em><em>the</em><em> </em><em>harmful</em><em> </em><em>rays</em><em> </em><em>of</em><em> </em><em>sun</em><em> </em><em>may</em><em> </em><em>enter</em><em> </em><em>the</em><em> </em><em>earth</em><em> </em><em>which may cause various problems in us and cause various diseases due to </em><em>which</em><em> </em><em>we ma</em><em>y</em><em> </em><em>die</em><em>.</em><em>the main thing is that we should stop the population growth, we should conduct public </em><em>awareness</em><em> program</em><em>m</em><em>e</em><em>s</em><em> </em><em>and many more </em><em>programmes</em><em> </em><em> to educate </em><em>people</em><em>.</em><em> </em><em>Population growth al</em><em>s</em><em>o</em><em> </em><em>creates</em><em> </em><em>deforestation</em><em> </em><em>as</em><em> </em><em>the</em><em> </em><em>number</em><em> </em><em>of</em><em> </em><em>people a</em><em>r</em><em>e</em><em> </em><em>increasing day by day they need more place to l</em><em>i</em><em>v</em><em>e</em><em> </em><em>,</em><em>they need more Land due </em><em>to</em><em> </em><em> </em><em>t</em><em>his </em><em>they</em><em> </em><em>cut</em><em> </em><em> down the trees of forest and used to make houses there due to </em><em>which</em><em> </em><em>d</em><em>e</em><em>f</em><em>o</em><em>r</em><em>e</em><em>s</em><em>t</em><em>a</em><em>t</em><em>i</em><em>o</em><em>n</em><em> </em><em>takes </em><em>place</em><em>.</em><em> </em><em>we all know that d</em><em>e</em><em>f</em><em>o</em><em>r</em><em>e</em><em>s</em><em>t</em><em>a</em><em>t</em><em>i</em><em>o</em><em>n</em><em> </em><em>is the process of cutting down </em><em>trees</em><em>.</em><em> </em><em>so the tree should not be </em><em>cut</em><em> down </em><em>as</em><em> </em><em>it</em><em> </em><em>is</em><em> </em><em>the</em><em> </em><em>source</em><em> </em><em>of</em><em> </em><em>oxygen</em><em> </em><em>for</em><em> </em><em>all</em><em> </em><em>creatures</em><em> </em><em>living</em><em> </em><em>in</em><em> </em><em>this</em><em> </em><em>whole</em><em> </em><em>world</em><em> </em><em>and the main thing is that we should provide education to the children and the youth and many </em><em>more</em><em>.</em><em> </em><em>if</em><em> </em><em>we are educated </em><em>we</em><em> </em><em>can</em><em> </em><em>stop</em><em> </em><em>such</em><em> </em><em>population</em><em> </em><em>growth</em><em>.</em><em> </em><em>so the main thing is that we </em><em>should</em><em> </em><em>stop population growth by giving </em><em>education</em><em>.</em><em> </em><em>Education</em><em> is the only one </em><em>way</em><em> </em><em>to</em><em> </em><em>stop</em><em> </em><em>such</em><em> </em><em>population</em><em> </em><em>growth</em><em>.</em>
Answer:
1. d. changes in the methylation patterns of <em>loci</em> involved in growth and metabolic disease
2. b. differences in the expression of metabolic genes
d. changes in histone acetylation patterns
Explanation:
Epigenetics refers to the study of heritable changes in gene expression which are not dependent on DNA sequence. Epigenetic mechanisms involve DNA methylation, histone modifications (acetylation, methylation, phosphorylation, etc) and regulatory non-coding RNA (ncRNA) pathways. These epigenetic mechanisms work together and mutually reinforce each other in order to modulate gene expression (either by activating or suppressing gene expression). In consequence, transcriptome data (e.g., genes differentially expressed in particular tissues/cells or stages of development) is an important piece of evidence indicating the existence of epigenetic modulation.

There's a bunch of examples.
For example, hairlines. A widow's peak is a dominant trait over a straigh hairline.
Or dominant hand type. Right hands are dominated over left hands.
Or hair types. Curly hair dominates straight hair.
If you google it, you'll get a lot more examples.
