The digestive and respiratory tracts include the pharynx. The pharynx is found at the back part of the throat and is connected to the mouth and the nasal cavity. It then extends to connect into the esophagus and larynx. The pharynx serves as passageway for air during respiration and food for digestion.
Answer:
Anaerobes carry on cellular respiration in the absence of oxygen, whereas aerobes carry on cellular respiration in the presence of oxygen.
Explanation:
Many of the cell processes needed need some energy to occur. Cellular respiration is the process by which cells degrade organic compounds and turn them into energy. Cellular respiration follows two ways, which depend on the presence or absence of oxygen, and both of them begin with the process of glycolysis, which occurs in the cytoplasm and does not need oxygen to occur.
<u>Aerobic Respiration</u>
- Occurs in the presence of free oxygen.
- Series of reactions by which pyruvic acid (product of glycolysis) turns into CO₂ and H₂O, producing many ATP molecules.
- Respiration occurs in the mitochondria.
- Takes place in two steps or stages: Krebs cycle and electron transporter chain.
- Glycolysis and Krebs cycle produce electrons, which then travel along the electron transporter chain while releasing energy, and ATP is produced.
<u>Anaerobic Respiration </u>
- Occurs in the absence of free oxygen
- Series of reactions by which using pyruvate (product of glycolysis) 2 ATP molecules van be produced.
- There are two ways in which anaerobic respiration can be produced: lactic fermentation and alcoholic fermentation.
- Lactic fermentation produces lactic acid and 2 ATP
- Alcoholic fermentation occurs in two steps, and the final products are ethylic alcohol, 2ATP, and 2 CO₂
- The whole anaerobic process occurs outside the mitochondria.
Remember for a di hybrid cross with two completely heterozygous parents, the phenotypic ratio will always be 9:3:3:1
9 will always display both dominant traits, black and rough hair. 3 will display black hair and smooth hair and 3 will display not black hair and rough hair and 1 will display both receive traits
The amino acids code for the protein. If one amino acid is changed then the whole protein is changed.
Yur answer would be A.exponential growth
hope it helped
