Flauer [41]

Answer:

It's impossible to predict the phenotype of the offspring by only observing the parents because DNA from their grandparents can affect the offspring as well.

Explanation:

DNA is combined from the parents to create offspring. When that offspring reproduces their children not only possess DNA from their parents but from their grandparents as well. Mixing together two separate DNA's from two different family trees can result in rare genetic mutations which results in the offspring looking different from their parents but showing resemblance to their grandparents. This is why you have to look at the phenotypes of more then just the two parents because there are more possibilities, including what their grandparents looked like.

What does she need from the food she ate and the air she breathes so that she can go on her run? How do Rosa's body systems work
IgorC [24]

The missing part of the question is as follows:

Rosa eats a peanut butter sandwich for lunch. Peanut butter contains a lot of protein, and bread is mostly starch. Rosa plans to go for a run later this afternoon. Rosa is breathing normally.

Answer:

1. The food she ate is peanut butter and bread, the peanut is rich in protein while the bread is rich in carbohydrate which provides sugar (glucose) by breathing she gets oxygen in a sufficient amount to perform cellular respiration (aerobic) to carry out energy for running. Carbohydrates are a better choice of nutrients befors exercise as carbohydrates provide energy immediately.

Aerobic respiration provides a high amount of energy, 36 ATP to be specific, per cycle of cellular respiration.

2.  The carbohydrates (glucose) and oxygen she gets from food and breathing react together to perform aerobic cellular respiration to carry out maximum energy. By the digestive system and organs of this system, carbohydrates are broken down into glucose which is diffused into the blood.

Oxygen also diffused to blood from the lungs and heart with the help of the respiratory and cardiovascular systems of her body.

3. By the aerobic cellular respiration process takes place in the mitochondria of the cell helps in providing energy from glucose and oxygen by a three-step process:

Glycolysis, the Krebs cycle, and oxidative phosphorylation. Here glucose reacts with oxygen. Which ultimately provide 36 ATP molecules for the cell in a run.
