Answer : The correct answer is -
D.Protista and Eubacteria.
Autotrophs are the organisms that can synthesise their own food using substances available in their surroundings with the help of either chemical energy (chemosynthesis) or light energy (photosynthesis).
Heterotrophs on the other hand, can not synthesise their own food and depend on either plants or animals.
Out of the given options, Protista and Eubacteria conatin autotrophs or heterotrophs.
Example- Protozoa (animal-like protists) are heterotrophs that ingest or absorb their food and helps.
Algae, which is a protist and obtains nutrition through photosythesis.
Slime moulds, which are fungus-like protists and are heterotrophic.
Cyanobacteria (also called blue green alage) is a photosynthetic bacteria (belongs to Eubacteria).
Answer:
Louis Pasteur
Explanation:
Gave theory of spontaneous generation that states, life arose from non-living things.
Sympatric speciation occurs when populations of a species that share the same habitat become reproductively isolated from each other. This speciation phenomenon most commonly occurs through polyploidy, in which an offspring or group of offspring will be produced with twice the normal number of chromosomes.
I'm not sure what YOU already know about photosynthesis and cellular respiration.... however, you SHOULD know that the two are beautifully linked to one another!
Photosynthesis equation:
6CO2+6H2O -> C6H12O6+H2O
Cellular respiration
C6H12O6+H2O -> 6CO2+6H2O
Notice something? The substrates of one equation are the products of the other! We rely on plants for their photosynthetic reactions - and plants benefit from us (not really because there is already a TON of CO2 in the atmosphere) from our cellular respiration
***we like their oxygen and they like our carbon dioxide!
:) I hope that helps! Let me know if you need any more elaboration!
Answer:Particle pollution and health risks, including premature death. Health effects may include cardiovascular effects such as cardiac arrhythmia´s and heart attacks, and respiratory effects such as asthma attacks and bronchitis.
