Answer:

Calcium Carbonate or Lime Stone

Explanation:

The outer hard shell of cray fish is made up of CaCO3 from sea sediments. It as analogue to the carapace of cockroach because both belongs to the phylum Arthropoda. Although they have different classes but their exoskeleton shares same composition and internal structure. Both use this to protect themselves against predators.

Energy extraction and the complete oxidation of foodstuffs requires three stages. The energy extracted from fuels is converted t
Rina8888 [55]

Answer:

C. In the third stage, fuel molecules are completely oxidized to CO2 , and most of the ATP needed for cellular processes is produced.

Explanation:

The three stages in the generation of energy from the oxidation of foodstuffs are given below:

First stage - This stage is the preparation stage and no useful energy is produced in this stage. In this stage, large molecules in food are broken down into smaller units. Proteins are broken down to amino acids, polysaccharides to simple sugars such as glucose, and fats are broken down to glycerol and fatty acids.

Second stage - In this stage, the various small molecules from the first stage are degraded to simple units (mostly acetyl-CoA) that are useful in metabolic activities of the body. Few ATP molecules are generated in this stage.

Third stage - In this final stage, most of the ATP required for cellular processes is produced from the complete oxidation of the acetyl unit of acetyl CoA to CO₂ in the citric acid cycle as well the oxidation of the electron carriers NADH and FADH₂ in oxidative phosphorylation.

m_a_m_a [10]

Answer:

Coriolis effect

Explanation:

The rotation of the Earth is one of the climate modifiers. Considering the speed of the rotation, it is no wonder that it manages to influence the air masses and their movement in the lower atmosphere. Because of the rotation of the Earth, the air masses tend to swirl counterclockwise in the Northern Hemisphere, and clockwise in the Southern Hemisphere. This process is causing lot of large cycles to occur on both hemispheres, and it is known by the term Coriolis effect.
