Answer:
Once you begin swallowing, the process becomes automatic. Your brain signals the muscles of the esophagus and peristalsis begins. Lower esophageal sphincter. When food reaches the end of your esophagus, a ringlike muscle—called the lower esophageal sphincter —relaxes and lets food pass into your stomach.
Sweat glands and sebaceous glands are exocrine glands. Pineal and adrenal glands are endocrine glands.
The frequency will be one in a ten thousand, in a real life situation. The X-linked recessive disorder has the same frequency as that of its frequency in the men. The frequency in women is close to zero, and in 5000 men, it will be one, so in total, the allele frequency will be 1/10000.
When we use a Punnett sqare, it comes out that 0% of the females will have he disease. But, as 50% of the eggs of the mother will carry a recessive allele, 50% of the male offprings bear the cahnces of being affected, i.e., 25% of the total offsprings, which mean 2500 male children bear the chance of having Hemophilia.
Energy is increases as frequency increases and wavelength decreases
Explanation:
The energy of wave is a function of its wavelength and frequency .
Wavelength is distance between two successive crests of a wave.
Frequency is the number of waves that passes a point per unit time.
Energy is directly proportional to the frequency of waves. The higher the frequency of waves the higher is its energy.
C = f ∧
C is the velocity of light
f is the frequency of wave
∧ is the wavelength of the wave
E = hf = 
= hf
h is the planck's constant
