5. Compare the energy emitted by waves with long <br> wavelengths to waves with short wavelengths

irinina [24]

Explanation:

The energy emitted by long wavelength waves are smaller to those emitted by short wave lengths.

The energy of a wave is a function of its wavelength and frequency.

The wavelength of a wave is the distance between its crest.
Frequency is the amount of waves that passes through a point in a period of time.
Energy of a wave is directly proportional to frequency and inversely proportional to wavelength.
The higher the frequency of a wave, the more the energy.
Waves with a high wavelength carries very little energy.
Long wavelength radiations have a long wavelength as the name implies. They carry very little energy and have low frequency. Examples are infra-red.
Short wavelength radiations have short wavelength. They carry very high amount of energy and have very high frequency. Examples are x-rays and gamma rays.

Calculate the mass defect for oxygen-16 given this data. Round to the 5es001-1.jpg decimal place. mass of an oxygen-16 atom: 15.

Naya [18.7K]

Answer:

Explanation:

Given parameters:

Mass of oxygen atom = 15.994914amu

Mass of a proton = 1.00728amu

Mass of a neutron = 1.00866amu

Unknown:

Mass defect = ?

From the periodic table, the number of the elementary particles in a neutral Oxygen atom is given below:

Number of protons = 8

Number of neutrons = 8

Number of electrons = 8

Solution

The mass defect examines the difference between the actual mass of an atom and sum of masses of the nucleons.

The mass of an atom is concentrated in the nucleus which contains protons and neutrons. Electrons have little to no weight compared with the nucleons.

To calculate the mass defect, we first know the mass of the nucleons first:

1 proton has a mass of 1.00728amu

8 protons will weigh: (8 x 1.00728)amu = 8.05824amu

For the neutrons:

1 neutron has a mass of 1.00866amu

8 neutrons will weigh: (8 x 1.00866)amu = 8.06928amu

Mass of the nucleons = mass of protons + mass of neutrons

= 8.05824amu + 8.06928amu

= 16.12752amu

The mass defect = mass of the nucleons - mass of the atom

= 16.12752amu - 15.994914amu

= 0.132606amu ≅ 0.13261amu to 5 decimal places

DELETION OF SNORD116, A PRADER-WILLI SYNDROME CANDIDATE GENE, DOES NOT AFFECT CIRCADIAN RHYTHMS IN MICE MODELS

Vlada [557]

Prader-Willi syndrome (PWS) is a gentic disorder which has an impact on numerous physiological systems. PWS affected individuals (specifically babies) experience delayed growth, significant hypotonia (low muscle tone), and feeding issues. It does effect circadian rhythms in mice models.

SNORD116, often referred to as HBII-85, is a non-coding RNA (ncRNA) molecule that contributes to the alteration of other small nuclear RNAs (snRNAs). Unlike the majority of other snoRNAs, SNORD116 is not significantly complementary to ribosomal RNA and is expressed widely in the brain (but not in PWS patients).

According to the studies, SNORD116 cause sleep defect in patients with Prader-Willi syndrome. Same observation was seen in mouse models too. Paternal expression of SNORD116 is thought to be a potential gene for the sleep disruptions/circadian rhythm’s that the majority of PWS sufferers.
