Answer:

evolution of life on Earth

Explanation:

Life began on Earth at least 3.5 to 4 billion years ago, and it has been evolving ever since. At first, all living things on Earth were simple, single-celled organisms. Much later, the first multicellular organisms evolved, and after that, Earth's biodiversity greatly increased.

What term is used to describe the relationship of the DNA strands to each other?
xxTIMURxx [149]

Answer:

The correct answer will be option-B.

Explanation:

Deoxyribose nucleic acid or DNA is the genetic material of the organism which is made up of nucleotide monomer. The structure of DNA is made up of two strands of nucleotides coiled in a helical structure thus providing a double-helical shape to the structure.  

Each nucleotide of a strand is composed of a five-carbon sugar, phosphate group and nitrogenous bases. These molecules are arranged in anti-parallel fashion in DNA which provides the polarity to the DNA strand. One strand is read from the 5' to 3' direction whereas another form 3'to 5' direction.

Thus, Option-B is the correct answer.

In "for more wonder, rewild the world," monbiot asserts that in the past, a far greater range of plant and animal species than w
kari74 [83]

George Monbiot is spearheading the Rewilding Movement. The environmentalist and writer is prominent in the platform. He was featured in TED Talk and talked about a large scale conservation approach aiming to restore the lost habitats. Here is an excerpt of his speech where he discusses the lost megafuna:

"What megafauna, you say? Well, every continent had one, apart from Antarctica. When Trafalgar Square in London was excavated, the river gravels there were found to be stuffed with the bones of hippopotamus, rhinos, elephants, hyenas, lions. Yes, ladies and gentlemen, there were lions in Trafalgar Square long before Nelson's Column was built. All these species lived here in the last interglacial period, when temperatures were pretty similar to our own. It's not climate, largely, which has got rid of the world's megafaunas. It's pressure from the human population hunting and destroying their habitats which has done so."

Consider a hypothetical food chain consisting of grass, rabbits, and foxes. The primary productivity of the grass is 200 units.
STALIN [3.7K]

The maximum amount of energy that we should expect to be recycled from fox trophic level back to the grass trophic level is 0 units.

A food chain describes who eats whom in the wild. Every living thing – from unicellular algae to giant blue whales – needs food to survive. Every food chain is a possible pathway that energy and nutrients can travel through an ecosystem. The primary productivity of the grass is 200 units. There is a 10 fold decrease in the amount of energy units as we move upwards in production chain. So from grass to rabbits we lose energy. The foxes will only really have two units once it's decreased by 10 fold again. The grass does not get any energy from the decaying bodies of foxes, they get the minerals that they need to grow.  And so the correct answer to this question is 0 units because when the energy gets recycled from fox trophic level back to the grass trophic level it will be totally reduced.

Note: The question seems to be incomplete. So the complete question is "Consider a hypothetical food chain consisting of grass, rabbits, and foxes. The primary productivity of the grass is 200 units. What is the maximum amount of energy that we should expect to be recycled from the fox trophic level back to the grass trophic level? Answer choices: A) 0 units B) 0.2 units C) 2 units D) 20 units"
