The primary products of the light independent reactions (after one turn of the cycle) are:
a) two G3P molecules
b) three ADP
c) two NADP+
However ADP and NADP+ are not really "products". They are regenerated and later used again in the Light-dependent reactions. Each G3P molecule is composed of three carbons.
For the Calvin cycle (Light independent cycle) to continue, 5 out of the 6 carbons provided by the two G3P molecules are used to regenerate ribulose 1, 5 phosphate. Therefore there remains only one carbon for the next turn of the cycle.
One molecule of glucose requires 6 turns of the cycle. Any extra G3P is used to make starch, sucrose and cellulose.
Fungi do have cell walls. Therefore A is ❎
Fungi and protist are eukaryotic. Therefore B is ✅
Fungi do not undergo photosynthesis. Therefore C is ❎
Fungi are heterotrophs, not autotrophs. Therefore D is ❎

Answer:
Lack of diversity = higher chance of extinction
high levels of diversity = higher chance of survival
Explanation:
The probable reasons behind the extinction of some Caminalcules are:
The ratio of males and females were not equal so that there were natural fight between male Caminalcules to get a female. This was one of the cause for lowering the population leading to extinction.
The excessive short-life of these Caminalcules was one of the main reason for their extinction as it is more difficult to real organisms because there would be an inherent bias against observing these species in fossil aseemblegs.
5. The two vestigial structures of Caminalcules were ear muscles and tail bones.
Epigenetic changes are those which do not involve alterations in the DNA sequence. These are caused due to interaction of the genome with the environment.
<h3>
When are alterations epigenetic?</h3>
- Epigenetic modifications or tags include DNA methylation and histone modification.
- These changes alter DNA accessibility and chromatin structure thus regulating gene expression.
- These are the reversible, heritable changes which do not change your DNA sequence, but they can change how your body reads a DNA sequence.
- These are necessary for the normal development of organisms.
- Stable, long-term epigenetic modifications involve DNA methylation.
- Flexible, short-term changes involve histone modifications, such as methylation and acetylation.
