The trunk of a tree carries out functions that are similar to the functions performed by which pair of human body systems?

Answers

Answer: The skeletal system and the circulatory system

Explanation:

The trunk of the tree helps in transporting the water and food materials to various parts of the plant.

The trunk of the plants provides it support and allows the movement of the substances from the roots to the other parts of the tree.

The skeletal system of the human body provides structural support to human body. The circulatory system of the body helps in transporting materials fro one part to another in the body.

the trunk of the tree is the main body and support of/for the tree, and just like our blood vessels has veins that carry water and nutrients

The second paragraph in the passage serves primarily to (A) outline the signifi cance of the 1981 discovery of conodont remains to the debate concerning the development of the vertebrate skeleton (B) contrast the traditional view of the development of the vertebrate skeleton with a view derived from the 1981 discovery of conodont remains (C) contrast the characteristics of the ostracoderms with the characteristics of earlier soft-bodied vertebrates (D) explain the importance of the development of teeth among the earliest vertebrate predators (E) present the two sides of the debate concerning the development of the vertebrate skeleton

Answers

Answer:

(E) present the two sides of the debate concerning the development of the vertebrate skeleton

Explanation:

In the paragraph, the author talks about two sides of view in the subject of vertebrates evolution. On one hand, he/she says that the first idea of vertebrates development is that the skeleton evolved as a defensive character and that many researchers rely on soft-bodied vertebrates to conclude it. On the other hand, he/she says that other researchers postulate that some vertebrate features (as paired eyes and adaptation in some muscles) could not have evolved if the first vertebrates were not depredators.

d. How are you going to put your chosen alternative into action?

HELP ME PLEASE!

Answers

Answer:

I will not allow due to presence of organisms there.

Explanation:

No, I will not allow the construction of the infrastructures on the large hectares of hills and forests because forests provides habitat to millions of organisms and also helps in preventing floods. I will suggest them to build infrastructure on the uncultivated land or choose a rocky solid land where vegetation is not possible. Rocky land is good for infrastructure because there is no vegetation cultivation is possible so the land is useless and good for infrastructure.

The _____ theory explains how our universe became so structured and uniform.big bang
inflation
steady state
oscillating

Answers

Inflation theory is the theory explains why our universe is structured and uniform and suggests that the universe is flat in shape. According to that theory, the universe expanded exponentially fast for a fraction of a second after the Big Bang.

inflation theory is correct i know this because the exact definition of the inflation theory is: theory that upholds the big bang theory, but suggests there was an extremely rapid expansion milliseconds after the big bang

Both Gregor Mendel and Alfred Wegener proposed ideas that were not accepted completely by the scientific community during their lifetimes. What did their ideas have in common?They were presented by amateur scientists who were not accepted by the scientific community.
They explained aspects of genetics that required Watson and Crick's data to be understandable.
They needed mathematics to prove their data, and that field was not developed at the time.
They required supporting evidence which could not be provided with the existing technology.

Answers

Correct answer: D). They required supporting evidence which could not be provided with the existing technology.

Both the scientist Gregor Mendel and Alfred Wegener proposed their idea but the scientific community do not believe to their ideas they talk about genetics and DNA and at that time the technology was not developed to study such information. So, they prove their ideas and theories but are not able to explain them to the people.

Hence, the correct answer would be option D.

They required supporting evidence which could not be provided with the existing technology!
