  • Answer:The septum is the cartilage in the nose that separates the nostrils.Typically, it sits at the center and divides the nostrils evenly.
  • The two atria are thin-walled chambers that receive blood from the veins. The two ventricles are thick-walled chambers that forcefully pump blood out of the heart. ... The right atrium receives deoxygenated blood from systemic veins; the left atrium receives oxygenated blood from the pulmonary veins.
  • A pacemaker is a small device that's placed under the skin in your chest to help control your heartbeat. It's used to help your heart beat more regularly if you have an irregular heartbeat (arrhythmia), particularly a slow one. Implanting a pacemaker in your chest requires a surgical procedure.
  • In a four-chambered heart, such as that in humans, there are two ventricles that operate in a double circulatory system: the right ventricle pumps blood into the pulmonary circulation to the lungs, and the left ventricle pumps blood into the systemic circulation through the aorta.
  • Your heart has four valves that keep blood flowing in the correct direction. These valves include the mitral valve, tricuspid valve, pulmonary valve and aortic valve. Each valve has flaps (leaflets or cusps) that open and close once during each heartbeat.

1. According to the graph below, what temperature will result in the highest rate of photosynthesis? A. 5°C
UNO [17]
<h3>✽ - - - - - - - - - - - - - - -  ~<u>Hello There</u>!~ - - - - - - - - - - - - - - - ✽</h3>

➷ It would be D. 25 degrees. This is because there was the highest oxygen  flow at this temperature meaning that the rate of photosynthesis was higher.

Compare and contrast three metabolic pathways by choosing whether the statement applies to aerobic respiration. Check all that a
Arte-miy333 [17]

Answer:

The correct answer will be options

1. Process includes glycolysis.

2. Between 2 and 38 ATP are produced per molecule of glucose input .

3. Much or most of the ATP produced is produced by oxidative phosphorylation.

4. Process involves electron transport and chemiosmosis.

5.  End products are CO₂ and H₂O.

6. Process involves the Krebs cycle.

Explanation:

Cellular respiration is the oxidative process which involves the breakdown of food molecules like glucose, amino acids and fats to release heat and energy in the form of ATP.

In the presence of oxygen or aerobic respiration it undergoes four stages: glycolysis, link reaction, Krebs cycle and electron transport chain while in the anaerobic reaction it produces ethanol and carbon dioxide by the process of fermentation.

Each stage produces energy in the form of ATP molecules or co-enzymes NADH OR FADH₂ like glycolysis produces 2 ATP and link reaction, Krebs cycle produces NADH OR FADH₂ in addition to ATP. Each NADH produces 3 ATP while Each FADH₂ produces 2 ATP during electron transport chain.  So, ATP molecules are produced between 2 to 38 ATP molecules in each stage with large number during electron transport chain from these co-enzymes.

The waste products produced in the stages of cellular respiration are CO₂ molecules and H₂O which is also known as metabolic water.
