what probability do we have of obtaining a purple flower (Rr), when we combine two blue flowers (rr) in an incomplete Dominance
34kurt

Answer: none

Explanation:

If we have that the color characteristic is regulated by the dominant gene R, by crossing two blue flowers with the recessive gene r, no violet flower will be obtained, since the rule of incomplete dominance describes that phenotypes can be obtained intermediates of homozygous parents, however in the case, we only have 2 parents with the same recessive conditions, which do not contribute to generate the violet, to produce one of the parents should have a gene that expresses the color red

Vladimir [108]

Maxine miles runs a marathon in 2 hours and 40 minutes. Most of the ATP for this activity is supplied by AEROBIC glucose breakdown. ATP is the energy coin of the cell.

Cellular respiration refers to the metabolic processes by which aerobic cells produce ATP by using the energy stored in the chemical bonds of foods (e.g., glucose) and oxygen.

Muscle cells can produce ATP by both cellular respiration (aerobic conditions) and acid lactic fermentation (anaerobic conditions).

Acid lactic fermentation is a less efficient pathway than cellular respiration, but cellular respiration is slower than fermentation, thereby muscle cells use this pathway (acid lactic fermentation) when there is not enough oxygen in the body.

The respiratory system ________. establishes how many breaths are taken per minute provides the body with carbon dioxide provide
kkurt [141]

Answer:

Provides body tissues with oxygen

Explanation:

The respiratory system supplies oxygen and removes carbon dioxide from the body, assisting cells in metabolism, acting in conjunction with the circulatory system, providing oxygen to body tissues. In addition, this system is related to smell, that is, our ability to allow odors and also related to speech, due to the presence of so-called vocal folds in one of the organs of the respiratory system.

This system is formed by the nose, nose cavity, pharynx, larynx, trachea, bronchi and lungs.
