The cardiac notch is a concave lung area where the heart accommodates. Its main function is to leave a space for the heart to lay. It is placed in the anteroinferior border of the superior lobule of the lung.

<u>Answer:</u>
<em>Climate change positively affects organisms by </em><em><u>providing them new habitat.
</u></em>
<u>Explanation:</u>
Climate change induces <em>changes in various parameters of an ecosystem </em>like temperature, precipitation, soil properties etc. habitats may undergo changes that make it unsuitable for native organisms to live in.
But this <em>new conditions</em> may be favourable for some other kind of organisms to thrive and flourish.
<em>For example, </em>when temperature of a lake increases due to climate change warm water aquatic organisms find a new habitat in the lake. But this threatens the life of <em>native cold water organisms of the lake. </em>
Thus climate change doesn’t bring any benefits to living world without harming one or the other <em>group of organisms.

Frameshift mutation affects codons downstream the point of mutation. The previous order of 3 nucleotide- sequences (codons) is consequently changed. This, therefore, changes the protein coded by the mRNA transcribed by the mutated DNA region. Frameshifts are mostly due to insertion or deletion mutations.
