Definition:
Having two different alleles of a particular gene or genes.
(an Allele is a variant form of a gene.)
Simplification:
If the organism has one copy of two different alleles, it is heterozygous.
Eg: T and t
<em> </em><em> </em><em> </em><em> </em><em> </em><em>(</em><em>T</em><em> </em><em>for </em><em>tall</em><em> </em><em>and</em><em> </em><em>t</em><em> </em><em>for</em><em> </em><em>short</em><em>)</em>
Example:
<u><em>Pea</em><em> </em><em>Plants</em></u>
Pea plants can have red flowers and either be homozygous dominant (red-red), or heterozygous (red-white). If they have white flowers, then they are homozygous recessive (white-white). Carriers are always heterozygous.
Bored* lol and being bored sucksss. What’s up
The Calvin Cycle, of which carbon fixation is the first step also occurs as part of the LIR and takes place in the stroma.

c.) enzymes and antibodies
Explanation:
DNA and RNA - nucleic acids
cholesterol and triglycerides - lipids
lactose, glucose, and sucrose - disaccharides
The forest A which is near to the village will be saved by the local volunteers and hence suffers less damage as compared to forest B which was far away. Both the forest will go under secondary succession.
<h3>What is Ecological Succession?</h3>
Ecological succession is the process of changes in the species structure of an ecological community over time. The time scale for a succession to take place can be decades or more or less.
Succession begins with a relatively few pioneering plants and animals and develops through increasing complexity until it becomes stable as a climax community.
The reason of succession is the cause of ecosystem change. It is the impact of established organisms upon their environments.
Succession is of two types: Primary Succession and Secondary Succession. When succession takes place on a bare rock then it is called primary succession as no species ever existed on that rock. However, when a forest catches fire the succession is secondary as species once existed on that place which were destroyed.
The time for secondary succession is less than the primary succession. The forest A which was near to the village will be saved by the local volunteers and hence it suffers less damage as compared to forest B which was far away.
