Evidence suggests that there is a relationship between ancient dinosaurs and modern birds throughout time each occurrence of a Nutri most likely resulted from which of the following

A mutation of genes

B extinction of populations

C Alteration of the environment

D hybridization of species

Evidence suggests that there is a relationship between ancient dinosaurs and modern birds throughout time each occurrence of a Nutri most likely resulted from mutation of genes.

Option: A

Explanation:

Out of the race of two-legged dinosaurs recognized as theropods the modern birds have been evolved, tenuously related to avians, generally their weight range from 100 to 500 pounds. This predicts the gigantic relative to most modern birds and they had big snouts, wide teeth, and not much between the ears. A velociraptor, for instance had a skull, like the one of a coyote and a brain about the size of a pigeon.

The premaxillary bones were recognized as two bones, which resulted into a beak in modern birds due to process of fusion. This arrangement is somewhat different from that of alligators, dinosaurs, ancient birds and rest other vertebrates, in which those two bones remained isolated, forming the beak. The investigators plotted the expression of two genes that are expressed in such bones in a variety of animals to determine how this transition could have occurred.

european union policies. the eu's long-term objective is to achieve levels of air quality that do not result in unacceptable impacts on, and risks to, human health and the environment. eu policies aim to reduce exposure to air pollution by reducing emissions and setting limits and target values for air quality.

the main environmental problems in western europe were: energy production/acid rain, nuclear power/waste, air pollution/climate, heavy metals, pesticides, water pollution, solid waste, and unforeseen accidents. many environmental problems are common to most european countries.

photosynthesis makes the glucose that is used in cellular respiration to make atp. the glucose is then turned back into carbon dioxide, which is used in photosynthesis. while water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
