<u>Answer</u>:- Option B Brown
<u>Explanation</u>:-
- When the beetles are living in a vegetation, then the most important point is that they are living in an environment where <em>green is the predominant color.</em>
- Since, the birds who will come to look for food, will have to identify the beetles against a green backdrop the green beetles are <em>most</em> safe as they can easily merge with their green surroundings. This is known as camouflage.
- The mixed beetles will be less fit as compared to the green beetles as the chances of them to be identified by the birds will be more as they are not completely green and are not able to fully merge with the surroundings.
- However, the brown beetles will be <em>least</em> fit to survive in this environment as they can be most easily identified against the green backdrop. They will be the most conspicuous of the three beetles. Thus, the birds will feed more often on the brown beetles and hence, they are least fit to survive in the vegetation.
This phenomena in which the organism who is best adapted to survive in a given environment and leave more progeny is termed as <em>survival of the fittest.</em>
Answer:
The correct answer is "Retinal".
Explanation:
Retinal, also known as retinaldehyde, is a form of vitamin A that plays an important role in vision. It was formerly known as retinene, and it comes from its name from retina, the thin layer of tissue that its inside the eye. Retinal is an important element in vision, it allows the conversion of light into metabolic energy.
The graph shows that the type of reproduction is ase xual reproduction. It is because the data tells us that the organisms were able to reproduce 300 offspring within three to four hours. The characteristic of an ase xual reproduction, which is able to reproduce in a short period of time, is evident in the graph.
Hope this answer helps ^^
Answer:
A bioindicator is any species or group of species whose function, population, or status can reveal the qualitative status of the environment.
Explanation:
Oxygen is required for aerobic respiration. This reaction produces ATP (universal currency for energy) which our bodies use to survive. Without oxygen much less ATP is produced, as aerobic respiration cannot occur in the lack of oxygen. ATP can be formed by anaerobic respiration, in the lack of oxygen, but this produces far far fewer molecules of ATP. This also produces lactic acid causing us to become fatigued and tired. Thus oxygen is crucial to produce the maximum amount of ATP possible.
Glucose is the main molecule which is respired by our bodies to produce ATP/ energy, which our bodies use to survive. Oxygen and glucose react in the mitochondria to make ATP (release energy.) It therefore, is called a respiratory substrate.
Note: I'm avoided talking about the exact phases of respiration as it is usually not covered till college/ A level standards. If you would like to know exactly which reaction requires oxygen and how it's used (i.e. the stages of respiration) don't hesitate to ask.
