Answer: Some adaptations that polar bear have to survive easily in tundra region are:

They have two layers of fur. Both the fur have different colors. One of the fur is white in color so that the bears can easily camouflage with the white snow that is present in the tundra region.

They have a layer of fat on their body which helps them to survive in colder region.

They hide in caves during the time of pregnancy to protect their children from danger.

Cell theory states that all living things contain one or more cells. Why do you think cell theory meets the definition of
Svet_ta [14]

Explanation:

OK, first of all, let me explain to you, what is a scientific theory...

A scientific theory is an explanation and demonstration of an aspect that exists in the natural world or universe that has been verified by the scientific way through repeated testing of the experiment with accepted protocols of observation, measurements and evaluation of results.

A scientific law is generated in the same procedure as above, but it can predict a wide range of natural phenomena.

Ex-: you are throwing a basketball from the top of a dam to the river. according to physics on earth, it should fall down. it's a law. no matter where you are, that basketball touches down the ground if there's any gravitational force.

But cell theory cannot be assumed to be common throughout the entire universe. Because we may find some other form of life that has some other plans. viruses are not obeying this theory.

*In a nutshell, a law is stable from its' origin. most of the time, it won't change. but theories will change with updating facts of science.

What is the difference between a GMO and cloning
viktelen [127]

Answer:

A GMO Genetically Modified Product though similar to cloning is quite different. Cloning is the process of using egg cells from an individual to produce a new organism. When the baby is born, it is genetically identical to the parent, an exact copy. This process occurs in a lab. Genetic Engineering, which is used to make GMOs,  uses technology to alter or change an organism's genes. New genetic information can be added to or removed from an existing set of DNA.

<em>So I would say that some of the differences between GMOs and cloning include that:</em>

Cloning strives to create exact copies of an organism's parent while GMOs remove and add different genes to form desired offsprings like making a product last longer or making the product grow larger faster.

Hopefully, this helped you! Have a nice day :)
