1. The complete breakdown of glucose in the presence of oxygen occurs in two stages: glycolysis and (). The first of these stage
Aliun [14]

Answer:

The complete breakdown of glucose in the presence of oxygen occurs in two stages: glycolysis and citric acid cycle. The first of these stages occur in the cytoplasm of the cell, and the second stage occurs in organelles called Mitochondria.

Explanation:

The breakdown of glucose occurs in two stages. The first stage occurs inside the cytoplasm, it is called glycolysis. when a molecule of glucose undergoes glycolysis, the following are produced:

2 ATP (Adenosine triphosphate) molecules;

2 water molecules;

2 pyruvate molecules and;

2 NADH (Nicotinamide Adenine dinucleotide) molecules

The second stage occurs in an organelle called Mitochondria, it is called citric acid cycle or tricarboxylic acid or Kreb's cycle. In this stage, the two pyruvate molecules from the glycolytic cycle are reduced to carbon(iv)oxide. The following are produced:

2 ATP molecules;

6 NADH molecules;

2 FADH2 (flavine adenine dinucleotide) and;

4 molecules of carbon(iv) oxide.

The NADH and FADH2 molecules are used in the electron transport chain generates as much as 28 ATP molecules.

while walking around a beach at low tide, you notice a bunch of oysters that appear to have been eaten by something. in the neig
alina1380 [7]

Probably the animal responsible for eating the oysters was the starfish, which are invertebrate marine animals that feed on molluscs such as oysters.

Starfish are echinoderms, have a central disc and about five arms, which give them a star appearance, justifying their name. They can be colored and their surface can be smooth or granular.

Their feeding occurs through a hydraulic system, they feed through the opening of the mouth and placing the stomach around the prey when feeding.

These animals are predators of invertebrates such as molluscs, crustaceans, sponges and corals.

D. Precipitation and temperature

Explanation:

The abiotic factors measured by the graph are precipitation and temperature.

  • Abiotic factors are the non-living component of the ecosystem.
  • They are temperature, pressure, soil, precipitation e.t.c
  • Precipitation is similar to rainfall and it is the product of condensation of water in the atmosphere.
  • A rain-gauge is used to measure the amount of precipitation in a place.
  • Temperature is the degree of hotness or coldness of a body.
  • A thermometer is used in measuring temperature.
