<h2>Obsessive-compulsive Disorder</h2>

Explanation:

  • OCD is one of the most widely recognized mental issue and about 2% of US grown-ups experience OCD sooner or later during their life. Of those, the greater part suffer manifestations that are amazingly serious and cause critical issues.
  • People are determined to have OCD at equivalent rates, yet men are bound to encounter side effects during youth. Around 25% of all instances of OCD are youngsters younger than 18, and 1/3 of grown-ups with OCD built up the confusion at a youthful age.  
  • Medicines for OCD as a rule include a blend of drug and psychotherapy, in view of the particular needs and indications of the patient. These medicines cooperate to improve working and reduction side effect seriousness after some time.

In general, locomotion on land will require more energy than locomotion in water. By integrating what you learned about animal f
denis-greek [22]

Answer:

  • Land animals require more energy since they have to overcome greater inertia during locomotion. Land mammals have adopted many evolutionary mechanisms to support high energy demand.
  • Heart is four chambered instead of the usual two in aquatic animals like fishes. More number of divisions in heart increases the efficiency of blood circulation process which in turn increases the oxygen delivery rate to cells for producing more energy.
  • Land mammals also have developed lungs which increase the efficiency of gas exchange process which increases the output of respiration process.
  • In addition, land mammals also have a strong and developed musculoskeletal system which helps in locomotion.

Alik [6]

The given question is incomplete, the complete question is:

Consider a simplified metabolic model to describe nitrogen metabolism in the body. Nitrogen is ingested in the food (F), a fraction of which is actually absorbed (A), the remainder being lost in the feces (W). The absorbed nitrogen is taken up by the muscle to make protein. At small fraction of the stored muscle protein undergoes degradation and the liberated nitrogen (L) is released from the muscle. Of the liberated nitrogen, a fraction is recycled back to the muscle (R), while the rest is lost to excretion (E) in the urine. If the nitrogen ingested in food is 100 g/day, but only 80% of the food is actually absorbed, while the rest goes to waste, what is the amount of nitrogen lost by excretion? Assume steady-state. Of the nitrogen liberated from muscle, 90% is excreted, while the rest is recycled, what fraction of the nitrogen entering the muscle is from the absorbed food? (In other words, what is the ratio A/(A+R)). Again, assume steady-state

Answer:

The amount of nitrogen lost in the process is 20 grams in a day and the fraction of nitrogen entering the muscle is 0.909.

Explanation:

Based on the given question, the amount of nitrogen absorbed is 80 percent of 100 grams, that is,  

100*(80/100) = 80 grams in a day.  

The concentration of nitrogen lost in the process is,  

Nitrogen ingested-nitrogen absorbed = 100-80 = 20 grams in a day.  

Let us assume that all the ingested nitrogen is liberated from the muscle. Therefore, 80 grams of nitrogen is liberated. If 90 percent of the nitrogen liberated from the muscle get excreted, then the value of excreted nitrogen will be,  

90% of 80 grams = 90/100*80 = 72 grams

Now the nitrogen recycled will be,  

Liberated nitrogen - excreted nitrogen = 80-72 = 8 grams

From the absorbed food, the fraction of the nitrogen entering the muscle will be,  

80/(80+8) = 80/88 = 0.909.

Explain the difference between absorption and transmission of light​
Mila [183]

Answer:

Absorption is the transformation of radiant power to another type of energy, usually heat, by interaction with matter. The transmittance t of a medium is defined by the ratio of transmitted radiant power to incident radiant power.

Have a nice day! :D
