The greatest number of shared derived characters should be found in two organisms that are placed in the same kingdom class.The biggest quantity of the offshore fields drives characters must be observed among the 2 organisms which are the member of the identical kingdoms magnificence area family
Shared derived tendencies derived tendencies, individual states which are shared through species and which are exceptional from the ancestral species. a collection or member this is intently associated however now no longer a member of the organization being studied.
Cladistics /Phylogeny- is a exceedingly new device of class that makes use of shared derived tendencies to set up evolutionary relationships. A derived trait is a function that advanced handiest in the organization beneathneath consideration. A phylogenetic tree primarily based totally on a cladistic evaluation is referred to as a cladogram.

Answer:
Abiotic is basically a non living factor so the answer is
D. Sunlight, temperature , conductivity, dissolved oxygen.
All other options contain one biotic or living factor like algae, star fish and crabs these aren't Abiotic.
They swam faster and learned to hide
The autotrophs are the primary producer in the food chain and they are the ones who initiate the food chain. They produce food by using sunlight or sometimes chemical energy or reactions. They primarily use carbon dioxide, sunlight and water to form sugars or carbohydrates which become their energy source. They use the process of photosynthesis or chemosynthesis to generate food. Examples of autotrophs are green plants, green algae, bacteria.
Heterotrophs cannot make their food via sunlight or other inorganic sources and hence are dependent on the autotrophs or other animals. The heterotrophs have been ranked as secondary and tertiary consumers and cannot be producers. They consume the organic products made by autotrophs to obtain energy for various metabolic and biological activities. The heterotrophs can be herbivore, carnivore, fungi, parasitic plants.
Some are photo-hetrotrophs, who use light as energy but cannot use carbon dioxide as the carbon source since they cannot fix the carbon like autotrophs.
Answer:
Genetic drift (sampling error)
Explanation:
According to the given information, the population under study has a small size and is more likely to be affected by genetic drift. Genetic drift refers to any chance event that leads to random changes in the allele frequencies of a population over time.
It may occur by sampling error that either makes the allele frequency 100% in the population or completely removes it from the population. Sampling error occurs quickly in the small population. The initial frequency of "blood type A" was 3/85= 0.035. Over the time period of 45 years, sampling error during gamete formation and random fertilization removed all the individuals with "blood type A" from the population and reduced its frequency to 0.
