Answer: Electromagnetic spectrum.
Explanation: It is composed of Gamma rays with the highest energy to radio waves with the lowest energy. It between in descending order (with regard to energy) is; X-rays, Ultraviolet, Visible Light, Infrared, Microwave. The higher the energy level the lower the wavelength and the higher the frequency.
Answer: Wavelength
Explanation: Ideally, the wavelength is the distance between two consecutive identical phases of a wave. It could be a peak to another peak or a trough to another trough. Usually, the lower the energy level of the wave, the bigger the wavelength and vice versa. It is measured in meters, millimeters or even picometers depending on the size of the wavelengths.
Explanation: Frequency is the amount of time that it takes for a wave to complete once a cycle, that is, to repeat a phase. Gamma rays have the highest frequency in the electromagnetic spectrum while radio waves have the lowest.
Explanation: Frequency is indirectly proportional to wavelength. This means that the higher the frequency the smaller the wavelength and vice versa. In addition, therefore, converse to wavelength, the higher the energy of a wave, the higher the frequency and vice versa. It is calculated by dividing one (1) with the wavelength of the wave. It is measured in Hertz
Answer: Telescopes
Explanation: Their basic principle of telescopes is that they collect as much light as possible from the aperture (this is why the front end is usually large diameter), and then converges this light using lenses and prisms onto a film. This gives a clear picture from which astronomical features can be clearly discerned,
Answer
The organism should be name as bacteria.
Explanation
Peptidoglycans is the characteristics features of bacterial cell its absent in cell wall of archaea, fungi and plant cell. Bacteria can also make amino acids. There are some bacteria who can prepare their own food in the presence of sunlight, i.e purple phototrophic bacteria, green sulphur bacteria, green filamentous bacteria etc. these bacteria contain photosythertic pigments called bacteriochlorophyll.
Clear wheat her from this prediction
Answer:
Has three dominant alleles
Explanation:
Skin colour is a polygenetic inheritance and it is controlled by three genes pairs of alleles. The human skin is determined by the amount of melanin it contains. A combination of melanin producing alleles determines the skin color.
In the above question, the person has a skin color that is midway meaning only half of the alleles produced melanin. The total number of alleles is 6 and half of it is 3. So, only 3 alleles were dominant and the remaining three were recessive.
I believe it’s the first option
