The benefits in synthetics are many, they have properties that we can't find in nature, they allow us to make things stronger, lighter, more fuel-efficient, shiner, longer lasting. And at the same time, we do add to the pollution of our world, affect the health of animals and humans, and requires energy to make.

Explanation:

Synthetic materials, also known as man-made or artificial materials, have made significant contributions to human society. Like Improved Performance and Durability, Expanded Range of Applications, etc.

Here are three ways in which synthetic materials benefit us:

Synthetic materials often possess superior properties compared to natural materials, such as increased strength, durability, and resistance to wear and tear.

Expanded Range of Applications: Synthetic materials have opened up new possibilities by offering characteristics that may not be readily available in nature.

Resource Conservation and Environmental Benefits: Synthetic materials can help conserve natural resources by providing alternatives to scarce or unsustainable materials.

Thus, while synthetic materials have numerous benefits, it is essential to consider their environmental impact throughout their lifecycle, including disposal and potential hazards.

Living things differ from non living things through motion, action, expression, way of living and etc......

Livings things:-

1. Livings things means something that keeps on moving or doing any particular work.

2. Livings things mostly consume, remove, and reproduce through different ways.

3. Examples of livings things are humans, animals, birds, reptiles, and even the germs like bacteria, fungi, ameoba and etc....

Non Livings things:-

1. Non Living things means something that just stays like a statue usually and never move or do a particular work.

2. Non living things do not consume, remove or reproduce anything.

3. Examples of non living things are table, chair, fan, house, book etc....

Answer:The answer to your question is Mg loses its valence electrons and acquire a positive charge (Mg⁺²).

Explanation:

Answer:

When it becomes an ion, it donates its valence electrons and becomes positively charged. The positively charged ion would be Mg²⁺ because it loses two electrons. It would have 12 protons and 10 electrons.

C- "able to talk"

Explanation:

Not all living things cant talk, but they all use energy, are made of cells and can reproduce.

Answer:

the squid population could decrease, because the tuna population is increasing and they would eat more squid, so the dolphin population would also decrease because there would be less squid to eat, and because there are less squid the herring population would increase.

In trophic webs, there is an equilibrium between species until a change occurs. The increase in tuna's population causes a decrease in dolphins' and squids' populations, and an increase in herring's one.

------------------------

To answer this question, let us first review some theoretical framework.

The trophic web is a relationship process between different organisms, through which occurs transference of energy.

The ones placed at lower levels pass energy to the ones at the higher levels.

Organisms at each level feed on the preceding one and become food for the next one.  

As it is a web, all organisms are equilibrated until a change occurs.

When the change affects any of the involved links, there can be a cascade effect on the web.

A change in a link population size (increasing or decreasing) will affect the superior links and the immediately anterior link.

Also, when two or more species are competing for the same source of food, a change in any of the population sizes will affect the other ones.

Now, let us analyze the exposed example.

We know that,

We need to figure out what is the cascade effect caused by the increase in the tuna population.

We know that tuna and dolphins compete for food items -squids-.

An increase in the number of tuna individuals means a higher competition pressure for dolphins.

The more tuna there are, the more squids they eat, and the less food available there is for dolphins.

Since there are not enough squids for dolphins, their population decreases in size.

Dolphins are negatively affected by tuna's increase.

**** Tuna population increases  ⇒  Dolphins population decreases ****

Tuna applies a significant predation pressure on squids, which are their main source of food.

The more tuna there are, the more squids they eat.

Squids probably can not reach sexual maturity or do not get to successfully reproduce, because they are eaten by tuna.

So squids population is negatively affected by the tuna population increase.

**** Tuna population increases  ⇒  Tuna population decreases. ****

Since squids feed on herring, any change in squids' population size affects herrings directly.

When the squids' population decreases in size, the herring population increases. More fishes get to survive and successfully reproduce.

The predation pressure of squids on herring decreases.

The herring population is positively affected by the squids' population decrease.

*** Squids population decreases  ⇒  Herring population increases. ***

Summing up, the cascade effect is as follows,

Answer:

friction

Explanation:

The rubbing of certain materials against one another can transfer negative charges, or electrons.

The friction generating between the surface of two objects causes the electrons to move from one body to the other and form static electricity. Hence, option c is correct.

Static electricity is the flow of electrons that occurs due to the temporary polarization of two bodies. When a conducting surface rub on other surface, they gets electrons by frictional force.

These free flow of electrons make them negatively charged. When this negatively charged body comes in contact with a non conducting surface they latter gets polarized by the electrons of negatively charged body.

The positive charges of the nonconducting surface gets attracted to the negative body and the electrons flow from the negatively charged body to the partially polarized positive body. This is called static electricity.
