PLEASE HELP! Emma prepared two glasses of water at two different temperatures. She added a spoonful of table salt to the cold wa
Sergio039 [100]

Answer:

The correct answer is - option B. No, the temperature in glass #2 is lower, which makes salt less soluble in water.

Explanation:

For the majority of the solids dissolved in water, the solubility increases with temperature increments. Higher temperatures accompany the increase in kinetic energy permits the solvent particles to more adequately break apart the solute atoms that shows intermolecular attractions.

So if glass one dissolves the salt faster than glass two then it is clear that glass one has more temperature than glass two that takes more time to dissolve the rock salt.

Thus, the correct answer is - option B. No, the temperature in glass #2 is lower, which makes salt less soluble in water.

Does an rh negative individual normally contain anti rh antibodies
fiasKO [112]
An Rh negative individual does not contain anti Rh antibodies. Rh- antibodies only develop in cases of pregnancy, miscarriage or a blood transfusion like if you have Rh-negative blood you got AB blood. The Rh-antibodies then work to attack the foreign substance, the RBCs. In the fetus, loss of RBCs means the rise of bilburin and could eventually lead to brain damage and also have low muscle tone.

All animals with eyes or the eyespots that have been studied so far share a gene in common. When the gene causes lack of eyes in
RSB [31]

Answer:

The correct answer is option C.

Explanation:

PAX5 refers to the member of the Pax gene family, which is, accountable for conducting the genetic information, which will encode the Pax-6 protein. It functions as a master control gene for the maturation of eyes and other sensory organs. Pax6 functions as a regulator in the formation of patterns and coordination needed for the proliferation and differentiation to take place effectively. This ensures that the procedures of oculogenesis and neurogenesis are taking place efficiently.  

The PAX6 gene was the outcome of evolution in earlier animals comprising eyespots or eyes. The similar PAX6 gene generates distinct kinds of eyes in distinct species because of the difference in its control of PAX6 expression. At the time of the evolution of vertebrates, the biological clock opsin’s rh gene was chosen as a gene for visual receptor pigments.
