Answer:
A & C
Explanation:
Primary producers are always at the bottom of the food chain because they are the entry point of energy into the ecosystem. The producers are organisms that produce their own 'food' from abiotic factors and include photoautotrophs and chemoautotrophs. These organisms are then consumed by primary consumers who are subsequently consumed by secondary consumers who are subsequently consumed by tertiary consumers to decomposers. The number of consumers up the food chains can vary with ecososyems and can be an indication of how biodiverse they are. This is how energy and matter are passed up an ecosystem and recycled.
Yes you can I am pretty sure and also add me as a friend lol I need friends and I’m bored lol
Answer: Option A) Double-stranded DNA
Explanation:
First, the presence of thymine infers that the genome is DNA.
Then, to determine whether it is single or double stranded, we check if the sum of all nitrogenous bases is equal to 100%
A + C + G + T = 100%
28% + 35% + 20% + 17% = 100%
Since all bases makes 100%, we can conclude that the genome is a double stranded DNA
Lactate is produced by fermentation
There are three major forms of fossil fuels and these are coal, oil and natural gas. All three were formed many millions of years ago before the time of dinosaurs.
Plants and trees died and sank to the bottom of swamps which filled the land. The dead matter formed layers of a spongy material called peat. Over time the peat was covered by sand, clay and other minerals which turned into sedimentary rock.
As the layers of rock piled up, their weight squeezed the peat until water came out of it and it eventually turned into coal, oil and natural gas.
