D. It becomes stronger.

Answers

Answer 1

Answer: A

Explanation: just took the test :)

Answer 2

The plastic that absorbs energy from sunlight becomes shrink. The correct option is B.

What are harmful effects of plastic?

Endocrine disrupting substances (EDCs) are among them; they have been connected to a number of diseases such as infertility, obesity, diabetes, prostate cancer, and breast cancer.

In addition to these problems, chemicals have also been related to issues of neurodevelopment, growth, and reproduction.

Chlorinated plastic has the potential to leak dangerous chemicals into the soil around it. These chemicals can then seep into nearby water sources, including groundwater, and the ecosystem.

The species that consume the water may experience a variety of potentially dangerous impacts as a result.

The plastic is exposed to sunlight, which oxidises it and converts the polymers into oligomers, extremely soluble organic molecules.

Plastic breaks down into smaller molecules and absorbs UV radiation from the sun, thus how quickly it decomposes depends on how much of it is exposed to sunshine. This process is known as photodegradation in science.

Thus, the correct option is B.

It takes just four hours for one bacterium to become _____.

Answers

Answer: 256 bacterium.

Explanation:

suppose a bacterium would divide once in every half an hour, this means it would be double in half an hour.

therefore, a number of the bacterium after half an hour will be 1 x 2 = 2.

After one hour, we would have doubled the number of bacterium =2 x 2

= 4.

Also, in one and a half hours, it would become 4 x 2

= 8.

In 2 hours, it would be 8 x 2 = 16.

Also in two and half hours, it would  be 16 x 2

= 32.

In three hours, it would be 32 x 2

= 64.

In three and a half hours, it would be 64 x 2

= 128.

Funally, in four hours, the number of bacterium would have been multiplied to 128 x 2

= 256.

It takes just four hours for one bacterium to become 256 bacteria.

It should be noted that a bacterium will divide once in every half an hour. This implies that it'll be double in every half hour. Therefore, for an hour, there'll be 2 bacterium.

Since it doubles every half hour, in 2 hours, the value will be 16 bacteria. Therefore, the value in four hours will simply be:

= 16 × 16 = 256 bacterium.

Therefore, it takes just four hours for one bacterium to become 256 bacteria.
