The cell continually produces carbon dioxide as a by-product of cellular respiration. How does the cell keep the carbon dioxide
ser-zykov [4K]

Answer:

Breathing out the carbon dioxide

Explanation:

Blood is the medium through which carbon dioxide is transported to the lungs from where it is exhaled out.

The Carbon dioxide produced in cells after respiration diffuses into the blood  in exchange of oxygen delivered to the cells for further respiration. Blood while flowing through the lungs passes carbon dioxide to its alveoli which is then exhaled out and oxygen is inhaled from outside.

Hence, cell keep the carbon dioxide from building up in the cytoplasm and poisoning the cell by exhaling CO2.

How can invasive species alter an ecosystems food web?
Harlamova29_29 [7]

Invasive species can either replace an organism from the ecosystem food web or replace it.  

Explanation:

  • Invasive species are non-native species which can be animals, plants, micro-organisms, fish, etc. they are very much threatening to the native species and ecosystem food web.
  • Invasive species are spread by humans mostly, it happens unintentionally when people travel and all. Even climate change could be a reason for its spread.
  • So, it becomes threatening to native species because when you introduce it into a new ecosystem, it does not have a predator or control. It grows aggressively and takes over the resources for the native species.

The substance dichlorophenyldimethylurea (DCMUDCMU) is an herbicide that inhibits photosynthesis by blocking electron transfer b
mario62 [17]

Answer:

No

Explanation:

During cyclic photophosphorylation, electrons are cycled continuously out of and back into the reaction center of PSI. It does not involve PSII and plastoquinone. During non cyclic photophosphorylation, the reaction center of plant photosystem II passes electrons to plastoquinone. The reduced plastoquinone carries electrons to the cytochrome b6f complex. Since PSII and plastoquinones are not included in cyclic photophosphorylation, dichlorophenyldimethylurea would not affect the process.
