Which of the following is true statement?

Elastic objects can be stretched and return back to their original size.
Elastic objects never go back to their original shape.
Elastic objects will always break when stretched.
Elastic objects can never be stretched.​

Answers

Answer:

Elastic objects never go back to their original shape.

Explanation:

When an elastic object is stretched beyond its limit of proportionality, the object does not return to its original length when the force is removed. In this instance, the relationship between force and extension changes from being linear, or directly proportional, to being non-linear.

Answer:

I don´t know if the other person is correct or not so don´t take my word for this but I think its A. Elastic objects can be stretched and return back to their original size.

How are water and minerals transported and used in vascular plants?

Choose all correct answers.


The phloem moves the food made in the shoots to all the other parts of the plant.

Vascular plants have leaves that absorb the water and minerals from the air.

The shoots are where the plant makes its food.

Hollow tubes called xylem carry the water and minerals up through the plant to the shoots.

Answers

Water and minerals are transported and used in vascular plants through :

A) Phloem moves the food made in the shoots to all the other parts of the plant D) Hollow tubes called xylem carry the water and minerals up through the plant to the shoots C) The shoots are where the plant makes its food

Transportation in Vascular plants

In vascular plants the root hairs in the root take up water and minerals from the soil and this water and mineral is transported to the shoot and leaves of the plants through a tissue known as Xylem.

The phloem transports the food made by the plants which is in the form of organic nutrients such as amino acids.

Hence we can conclude that the correct options to your question are as listed above.

How can nearly all energy on earth be tracked back to nuclear fusion?

Answers

Answer: see if this helps Nuclear fusion seems a great solution for the demand of Energy. It is safe, has infinite fuel, produce a negligible amount of waste etc.There are enormous technical challenges still to overcome, but let’s assume one moment, for the sake of the argument, that we find a way to solve them and the power plant is now “technically ready”.Reading around seems that the cost of such plant will be huge: a lot of material required, complexity in the construction etc. Such construction costs include a very relevant energy price. For instance digging all the material and “transform” them requires a lot of energy. I have the feeling that the energy produced all over the life cycle has the same order of magnitude: i.e. at the end the “net balance” is not so convenient. Considered the huge capital cost the ration “Net energy produce / cost” would be quite poor as well.

What do you think Newton meant when he said, “If I have seen further [than most people], it is by standing on the shoulders of giants”?

Answers

Answer:

Newton meant to say that even the biggest scientist had made mistakes and so did he in his experiemnts and that they all learned from each others ideas

Newton intended to imply that even the most accomplished scientists made errors, just as he did in his experiments, and that they all benefited from one another's insights.

What do you think Newton meant?

The term is considered to suggest that Newton was working in the context of findings made by previous scientists, either in his own time or earlier.

If I have seen further, it is because I have been supported by giants. Since it occurred in a letter he addressed to fellow English scientist Robert Hooke on February 5, probably in 1675 or 1676, this quotation has been credited to Sir Isaac Newton.

Describing how his innovations (and those of others) were made possible by the fact that they built on earlier concepts and accomplishments.

Therefore, There is no disputing that Newton is the author of this statement.

Examine the words,
impulse, presynaptic cell, neurotransmitters, receptors, postsynaptic cell,
What idea can be described using all the words listed?

Answers

The synapse is the place where the electrical impulse is modulated, it begins with a chemical-electric discharge in the presynaptic cell and the postsynaptic cell has the receptors that receive and are activated by the neurotransmitter.

What is synapse?

It is the functional relationship of contact between the endings of nerve cells.

This communicative process between neurons begins with a chemical-electric discharge in the membrane of the emitting cell (presynaptic cell).

When said nerve impulse reaches the end of the axon, the neuron secretes a substance that lodges in the synaptic space between this transmitting neuron and the receiving neuron (postsynaptic cell), in turn, this neurotransmitter is responsible for exciting another neuron.

Therefore, we can conclude that the synapse is the place where the electrical impulse is modulated, it begins with a chemical-electric discharge in the presynaptic cell and the postsynaptic cell has the receptors that receive and are activated by the neurotransmitter.
