The answer is C.
It is not true that CO2 is released during photosynthesis, rather its the opposite. Carbon dioxide is a raw material for the production of starches and cellulose through photosynthesis. Atmospheric carbon dioxide is captured during the light dependent reactions of photosynthesis then used for the production of starch, glucose and cellulose in the light independent reactions (Calvin cycle) of photosynthesis.
In aerobic cellular respiration, oxygen rather than Carbon dioxide is a requirement because it is needed as the terminal electron acceptor in the production of ATP.
The correct answer is d: '<span>the protective coats of both groups are made of chitin'
Chitin is </span><span>a long-chain </span>polymer <span>derivative of </span>glucose, with a structural function in various groups of animals and plants, such as <span>of </span>cell walls<span> of </span>fungi<span>, </span>exoskeletons<span> of </span>arthropods <span>and the scales of </span>fish. It can be compared in function to keratin found in our hair and nails.
It can be classified in the phylum chordata.
Phylum : chordata
Sub-phylum: Vertebrata
Division: Gnathostomata
Superclass: pisces (respiration occurs typically by gills)
The statements All living things maintain relatively constant internal conditions, living things are made of one or more cells, and living things perform chemical reactions are TRUE.
<h3>What are organisms?</h3>
Organisms are living forms or biological entities that are independent and are composed of one or more cells, thereby viruses are not living forms.
In conclusion, the statements All living things maintain relatively constant internal conditions, living things are made of one or more cells, and living things perform chemical reactions are TRUE.
