Answer:

The correct answer will be options A, B and E.

Explanation:

Energy flow is the directional path of transfer of energy from one organism to another through a biological food chain.

The autotrophs or producers are present at the lowest trophic level which are capable of converting the sunlight energy to chemical energy or food via photosynthesis, therefore, receives maximum energy so accumulate high amount of biomass.  

Energy flows in ascending manner usually from the lowest trophic level to highest trophic level that is from autotrophs to herbivore to carnivores in a food chain by a law called ten percent law. So, the carnivores at the highest trophic level receive less energy as compared to another trophic level.

Thus, options A, B and E is the correct answer.

Mitochondria, the organelles involved in cellular respiration, can also generate chemicals called reactive oxygen species (ROSs)
ch4aika [34]

<u>Answer:</u>

Mitochondria, the organelles involved in cellular respiration, can also generate chemicals called reactive oxygen species (ROSs). ROSs can damage mitochondria. Damaged mitochondria generate more ROSs than healthy mitochondria. This is an example of a positive feedback mechanism

The reactive oxygen species that are given out by the mitochondria during cellular respiration are the major cause of aging. Though this has a lot of negative effects but this also has a small amount of positive effects such as the start of angiogenesis or cell proliferation.

The illustration shows biotic and abiotic factors in a pond ecosystem. Which are biotic factors of the pond ecosystem?
Hatshy [7]

Answer:

All organisms that have life, both plants and animals.

Explanation:

You didn't provide an illustration, but I guess I can still help. Biotic factor means that it has life, abiotic means it's not alive (hence the a- at the beginning.) Some biotic factors of a pond ecosystem include: earthworms, fishes, frogs, plants and insects.

Which evolutionary mechanism caused the increase in dark-colored Biston betularia moths in England in the 1800s? genetic drift n
SashulF [63]

Answer:

Natural Selection is an evolutionary process that caused the increment of dark-coloured Biston betularia moths in England. It happened due to increase of air pollution in the industries. The bark of the trees became darker because of the deposition of pollutants.

In order to save itself from predators, the species of Biston betularia evolved itself to a dark coloured species so that the predators gets confused between the bark of the tree and the Biston betularia.
