If it goes in the nostrils the air is warmed and humidified. The tiny hairs) protect the nasal passageways and other parts of the respiratory tract, filtering out dust and other particles that enter the nose through the breathed air.
The answer is B. This the systolic pressure of a giraffe in comparison
to that of a human that is 100 mm Hg. This
high blood pressure ensures that the giraffe maintains 100 mmHg in the brain.
Since a high BP impairs gas exchange and increases transpulmonary filtration,
the pulmonary circulation must be separated. Therefore, in the giraffe, there
is a relatively great difference between the right ventricular and left ventricular
maximal rates of pressure ascent, the left ventricular rate of ascent being 5
times that calculated for the right ventricle.
The complete flower contains both male and female reproductive parts. It has all four parts, that is stamen, pistil, sepals, and petals.
Hence pumpkin is a incomplete flower.
Therapeutic cloning is the
process of creating multiple copies of a cell to treat a disease. In this type of cloning, the nucleus of a
cell, such as a skin cell, is inserted into a fertilized egg whose nucleus has
been removed. The nucleated egg begins to divide repeatedly to form a
blastocyst. Stem cells are then extracted from the blastocyst and they are used
to grow cells that are a perfect genetic match for the patient. The cells
created through therapeutic cloning can then be transplanted into the patient
to treat a disease from which the patient suffers.
