Answer: -

b. Oceanic crust is denser than continental crust, causing oceanic crust to sink down below continental crust.

Explanation:-  

Oceanic crust is denser than the continental crust as it has iron, basalt, magnesium. On the other hand continental crust consists of granite and aluminium. The rocks that have oceanic crust are thus denser than the rocks that have continental crust. Continental crust is considerable thicker.

Due to the difference in the density when oceanic crust and continental crust meet at the subduction zones, the oceanic crust is sub ducted back into the mantle. Continental crust is the oldest part and underlies beneath the continent.

A layer of sedimentary and metamorphic rocks too form on the tops of the continental crust.On the basis of the above explanation, Oceanic crust is denser than continental crust, causing oceanic crust to sink down below continental crust is the correct option.

Sindrei [870]

Answer:

The predicted genotype of the offspring is GgRr.

Explanation:

The gray body is dominant over black body. The genotype of gray body is GG and the genotype of black body is gg. Red eyes are dominant over orange eyes. The genotype for red eye is RR whereas the genotype of orange eye is rr.

GGRR is crossed with ggrr, the offspring produced by this cross is GgRr with gray body and red eyes.

GGRR  ×   ggrr

 GgRr.

trapecia [35]

Answer:

Breathing rate is most likely to increase if the blood level of carbon dioxide increase.

Explanation:

Breathing rate is the number of breaths of a person during a specific time, is usually the number of respiratory cycles that occur per minute. External respiration is the process of exchanging oxygen and carbon dioxide from the outside of the human body to pulmonary capillary blood. Once in the lungs, oxygen (and carbon dioxide to a very small extent) through the alveoli, pass into the red blood cells of the pulmonary vein blood. Carbon dioxide reacts in the blood with water, thanks to an enzyme, giving rise to bicarbonate. Blood reaches the heart, and is pumped into the cells by systemic arteries. The oxygen in the blood crosses the cell membrane and in turn, an exchange occurs, since the cell expels carbon dioxide and oxygen that it has not used. Once the exchange is done, the blood is conducted through the systematic veins with oxygen whose partial pressure is lower, and with an increase in the partial pressure of carbon dioxide. It reaches the heart again, leads through the right atrium and ventricle and finally travels through the pulmonary artery to the lungs where the air is expelled (expiration). Breathing rate tends to increase when the level of carbon dioxide in the blood increase.

To prevent UTIs, the nurse teaches the client to void (empty) immediately after sexual intercourse.

<h3>What are urinary tract infections (UTIs)?</h3>
  • UTIs are commonly occurring infections that occur when the bacteria, quite often from the skin or rectum, enter the urethra and infect the urinary tract.
  • The infection may occur in any part of the urinary system i.e. the kidneys, bladder and the urethra.
  • These infections are commonly occurring in women.
  • The symptoms include pelvic pain, strong urge to urinate, pain with urination, cloudy urine and blood in the urine.
  • To prevent UTIs, drink plenty of water, empty your bladder soon after intercourse, drink cranberry juice and avoid irritating feminine products.
  • The easiest way to prevent UTIs is to flush the bacteria immediately out of the urinary tract before it starts to grow there. Therefore, drink lots of water.
