Answer/Explanation:

Only the soft tissue is preserved. Normally the hard tissues are preserved(bones). But since the bones decomposed and was later filled with sediment, only the soft tissue was actually left by the animal.

Explanation:

Alcoholic Fermentation is a biological fermentation process in the absence of oxygen (- O2), caused by the activity of some microorganisms that process carbohydrates (as a rule, sugars: for example, glucose, fructose, sucrose , that is, any substance that has the empirical form of glucose, that is, a hexose) to obtain as final products: an alcohol in the form of ethanol (whose chemical formula is: CH3-CH2-OH), carbon dioxide ( CO2) in the form of gas and adenosine triphosphate (ATP) molecules consumed by the microorganisms themselves in their anaerobic energy cellular metabolism. The resulting ethanol is used in the production of some alcoholic beverages, such as wine, beer, cider, cava, etc. At present, ethanol has also begun to be synthesized through large-scale industrial fermentation to be Used as a biofuel.

Alcoholic fermentation has the biological purpose of providing anaerobic energy to unicellular microorganisms (yeasts) in the absence of oxygen from glucose. In the process, yeasts obtain energy by dissociating glucose molecules and generate alcohol and CO2 as waste. The yeasts and bacteria that cause this phenomenon are very common microorganisms in fruits and cereals and contribute greatly to the taste of fermented products (see sensory evaluation) One of the main characteristics of these microorganisms is that they live in completely lacking environments of oxygen (O2), especially during the chemical reaction, and that is why alcoholic fermentation is an anaerobic or anaerobic process.

The geographic isolation of a population from other members of the species and the subsequent evolution of reproductive barriers

Ber [7]

Answer:

4 allopatric

Explanation:

The formation of a new species can occur in several ways. One such process is the separation of two populations of a species geographically. The presence of any geographical barrier may separate the two populations from each other. These populations accumulate variations over time. After several generations, the members of these two populations can not interbreed successfully and are said to be reproductively isolated. The two populations are now two different species. This is called allopatric speciation.
