How does cladistics us understand phylogeny?

a.) cladistics is based on the shared characters between organisms and their network of evolutionary relationships.
b.) cladistics is based on ranking organisms in evolutionary history and predicting prospective future species.
c.) cladistics is based purely on the shared characters between organisms and their ranking in evolutionary history.

The correct answer will be option-C

Explanation:

Cladistics is the approach used to classify the organism based on their shared characters on the basis of which the closely related organisms are grouped together.

The evolutionary biologist studies the physiological, genealogical, molecular and morphological characters on the basis of which the phylogenetic trees are constructed. In phylogenetic trees, the organisms are arranged according to their evolutionary history.

Thus, Option-C is the correct answer

name and explain one of the event that occurs during meiosis that increases the variation in offspring even more than simple reproduction?

ecological efficiency: % of usable energy transferred as

biomass from one trophic level to the next typical is 10% efficient (90% of

energy is lost),is diagramed as the pyramid of energy flow. then osprey eagle

are tertiary consumer and the shrimp are primary consumer, so to balance

mass of shrimp (1/0.1) / 0.1 = 100 kg
