Answer: After several days, a large bubble of gas collected in the upside-down beaker contains OXYGEN.
Explanation:
Plants are known to be be autotrophic (producers) through the use of inorganic substance such as water, carbondioxide and light energy from sunlight in a process known as photosynthesis.
An experiment was carried out by Latecia for investigation of the gas production of a water plant. It's therefore expected that OXYGEN gas which is the by-product given off during photosynthesis in green plants would be collected from the upside down beaker as gas bubbles.
Answer:
The pyrenoid, a dense structure inside or beside chloroplasts of certain algae, consists largely of ribulose biphosphate carboxylase, one of the enzymes necessary in photosynthesis for carbon fixation and thus sugar formation. Starch, a storage form of glucose, is often found around pyrenoids.
If reproduction didn't exist, all species would eventually go extinct.
Answer: B. Fox nests
Explanation:
Foxes dig out dens to provide a safe underground space that is mostly used for raising fox cubs, also called kits. In urban areas, the dens - known as earths - are commonly located under sheds, but they can also be among tree roots, in bushes or on railway embankments.
Answer:
Survival of the Fittest means that animals best suited to a certain area will survive, not that the largest will survive. An example of this is the mouse.
Explanation:
When an animal adapts to live longer, they are adapting to their predators and their environment. For smaller animals, like mice, being big might mean that hawks are able to find them easier, leaving only the small mice to reproduce. I hope this helps!
