These lines (there is four of them) are residuals of the fusion of the five sacrum vertebrae that are fused. These "vertebrae" or segments present a characteristics, being the first of them very similar to a lumbar vertebra, large, and the other vertebrae are<span> progressively smaller and flattened. They also present a curved shape being anteriorly concave.</span>
<u>Answer:</u>
Common ancestor is the main factor that determines that all terrestrial animals are quadrupedal.
<u>Explanation:</u>
- Phylogeny means the evolution of the organisms or genetically related organism and how they are related.
- The study of phylogeny is called as phylogenetics. Terrestrial means those who live on land.
- Mammals are one who gives birth to their offspring directly. They are generally warm-blooded, breath air.
- Studying each state of the ancestor and also tracing the organism characteristics during evolution.
A vinegar flavor
The fermentation of food is the breakdown of the food molecules, anaerobically.
Explanation:
Usually, anaerobic bacteria or yeast are able to break down molecules like glucose in the absence of oxygen because their main cellular respiration metabolic chain is glycolysis. The pyruvate that is formed at the end of glycolysis is readily converted to lactic acid by the cells before being excreted by the cells. This is why fermented food tastes sour like vinegar. Sourness is a general characteristic of acids.

The theory of natural selection was first expounded by Charles Darwin and today it is believed to be the main process that brings about evolution.
This process is defined as the process whereby organisms who better adapt to their environment tend to survive and produce more offspring.
Hence, according to this statement, option C is correct.
More organisms are born than can survive.
To assist individual and for communities to function as effectively as possible in the major domains of living.
