More details are required to answer the question.

The K-t boundary or the Cretaceous-Tertiary boundary signifies the beginning of the Tertiary and the end of the Cretaceous; sixty-five million years ago. The boundary can be observed in various locations across the globe and is a relatively thin layer of dust sediments with an abnormally high amount of iridium.
Iridium is a rare earth element and is only found in large amounts in asteroids. This knowledge led scientists to conclude that the debris deposited was caused by a massive asteroid impact.
The impact crater was eventually located and was found just of the coast of the Yucatan peninsula. The asteroid was over ten miles in diameter and this impact was thought to be instrumental in the extinction of the dinosaurs.

In the combined processes of glycolysis and cellular respiration, what is consumed and what is produced?.
IrinaVladis [17]

Glucose is consumed and carbon dioxide is produced during the combined processes of glycolysis and cellular respiration.

Glucose is a simple sugar. Glucose is the most common monosaccharide, a type of carbohydrate. Glucose is primarily produced by plants and most algae during photosynthesis from water and carbon dioxide with the help of sunlight, where it is used to produce cellulose in cell walls, the world's most abundant carbohydrate.

A glucose molecule is gradually broken down into carbon dioxide and water during cellular respiration. Some ATP is produced directly along the way in the reactions that transform glucose. However, much more ATP is produced later in the process known as oxidative phosphorylation. The movement of electrons through the electron transport chain, a series of proteins embedded in the inner membrane of the mitochondrion, drives oxidative phosphorylation.

During glycolysis, a six-carbon sugar, glucose, undergoes a series of chemical transformations. It eventually degrades into two molecules of pyruvate, a three-carbon organic molecule. ATP is produced in these reactions.

Explain in your own words why a dominant trait is not always a common trait.
taurus [48]

Answer:

Describing a trait as dominant does not mean it is the most common; it means that it is expressed over the recessive trait. For example, tongue rolling is a dominant trait, controlled by the dominant version of a particular gene (R). Individuals with one or two copies of R will exhibit tongue rolling.
