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.
Answer;
DNA or protein sequences of shared genes
The MOST accurate way to determine the evolutionary relationship between two animals is through the examination of DNA or protein sequences of shared genes.
Explanation;
DNA or protein sequences of shared genes. Biochemical evidence is extremely accurate in determining the relationship between two organisms. Many animals have been re-classified, due to DNA evidence.
The ability of an organism to maintain internal conditions is called <em>C homeostasis </em>
<h2>Kelp forests decline</h2>
Explanation:
- Kelp forests rely on the proper balance of herbivory and predation
- Sea urchins dwell on the seafloor where they forage on macro algae, including giant kelp,if their populations are left unchecked by predation they can prevent kelp from growing which can transform a thriving community of kelp into an oceanic desert, known as an urchin barren
- If there is a decline in sea urchin population then there will be an increase of kelp population because it lost a predator
- The kelp crab will diminish because the sea otters would prey on them more often after losing a food source and the sea otters population will also decrease with time
- The horn sharks will slowly die from the lack of food because sea urchins were their only prey and the northern elephant seals will decline as well because of the death of horn sharks
- Hence, the decline in sea urchin population will upset the entire kelp population
