The answer is A
Aquifer is an underground source of water. It is an underground of water bearing permeable rock, it must be both permeable and porous and include rocks such as sandstone, conglomerate, fracture limestone and unconsolidated sand and gravel. The water can be extracted fro aquifer using a water well.
Answer:
Given,
Colourless molecule is converted to black pigment by enzyme A. Black pigment is converted to agouti pigment by enzyme B.
Parent 1: AAbb = Black
Parent 2: aaBB = Colourless
AAbb X aaBB = AaBb (F1) The entire progeny is agouti coloured since dominant alleles for both the genes are present.
When AaBb X AaBb according to dihybrid cross in F2 :
A_B_ = 9 ( Agouti )
A_bb = 3 ( Black )
aaB_ = 3 ( Colourless )
aabb = 1 ( Colourless )
Hence genotypic ratio is 9 : 3 : 3 : 1
and phenotypic ratio is 9 (agouti) : 3 (black) : 4 (colourless)
Answer:
Eosinophil.
Explanation:
The human blood consists of the plasma, red blood cells, white blood cells and the platelets. The white blood cell of the body helps in providing protection from the body and fights with he pathogens.
The granulocytes of the white blood cells include eosinophils, basophils and neutrophils. The eosinophils are the first cells that reach at the injury might occur due to the worms and nematyhelminthes. They have bilobed nucleus and stain orange with the basic dyes.
Thus, the answer is eosinophil.
Answer:
False
Explanation:
There are 7 major and 8 minor tectonic plates. There are certainly not fifty. There are only about 15.
