Chromosomes are long molecules of DNA that contain some or all of an organism's genetic material. In most chromosomes, very long, thin strands of DNA are coated with packaging proteins. In eukaryotic cells, the histones are the most important of these proteins.

Within the nucleus of all cells, DNA molecules are packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA tightly wrapped many times around proteins called histones that support its structure.

Another type of cell division, meiosis, ensures that humans have the same number of chromosomes from generation to generation. This is a two-step process in which the number of chromosomes is halved from 46 to 23 to form sperm and eggs.

Electromagnetic waves are all around us T or F

Law Incorporation [45]

Answer:

2. True, 3 True, 4 Trues, 5 False, 6 True, 7 True, 8 False, 9 True, 10 True

Explanation:

3. True , Electromagnetic waves have electric and magnetic energy while ocean wave have kinetic energy which is then converted into electrical energy.

4. True, the distance between all the wavelength is same until and unless it not dampened or attenuated or amplified.

5. False, Frequency measures the number of times an event takes place in a given time period.

6. True, the higher is the frequency , the more will be the energy

7. True, Gamma waves have highest frequency

8. False, our eyes could see only visible spectrum wavelengths

9. True, some object or surfaces reflect the wavelength while some absorb it.

10. True, all cosmic researches are driven by EM waves theory and related logic.
