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

Off the Monterey Bay coast in California there is a kelp forest. The kelp grows talls and sways in a sea full of sunshine. It
provides a protective habitat for many maturing species. The kelp is consumed by sea urchins which are consumed by sea otters. Over fishing in the ocean reduced the food for killer whales so they came close to the coast to prey on the sea otters. The drop in sea otters caused a rise in sea urchins which greatly reduced the kelp.
In this ecosystem, the _______

A plate moves 200 m in 10,000 years. What is its rate in cm/year
Answer:
0.2 or 1/5 centimeters per year
Explanation:
to solve this equation you must turn meters into centimeters
you can do this by mlultiplying it by 100
200 cm in 10000
then you must divide both sides by 10000
2/100 or 0.2 centimeters per year

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.
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 foodTransportation in Vascular plantsIn 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.

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”?
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.

Which of the following describes a phenomenon that occurs when we observe plants that wilt?
A. The roots begin to rot, causing them to no longer uptake water.
B. The xylem releases all its water.
C. The stomata close, cutting off transpiration and gas exchange.
D. The plant begins absorbing oxygen and releasing carbon dioxide into the atmosphere.
The xylem releases all its water when we observe plants that wilt.
Answer: Option C
Explanation:
Wilting is a process where the plant loses its rigidity and droops down. To understand it better the water is absorbed through the roots and aids in the functioning of the plant. The excessive water is stored inside the vacuole when during water scarcity releases water.
But during the drought conditions the water is lost completely causing the leaves to shrink. The xylem starts releasing all its water leaving a less surface area. Hence the leaf shrinks and wilting occurs.
What does a leaf absorb and release so photosynthesis can take place?
I’m not sure if it’s oxygen or not.
Answer:
Chlorophyll's job in a plant is to absorb light—usually sunlight. The energy absorbed from light is transferred to two kinds of energy-storing molecules
