Adithya Dev A 4 years, 5 months ago

[(5x - 4y = -8) * 3] + [(7x + 6y = 9)] * 2 ==> (15x - 12y = -24.) + (14x + 12y = 18.) ==> 29x = -6. ==> x = -6/29// Therefore, y = 9 - 7x /6 = 9 + 42/29 / 6 = (261 + 42/29) / 6 = 303 / 174 = 101/58//

What do you mean by dental caries??

Posted by Rupesh Kumar Yadav 4 years, 5 months ago

CBSE > Class 10 > Science

1 answers

Adithya Dev A 4 years, 5 months ago

Dental caries occur when acids are produced in our mouth. If we don't rinse our mouth after eating food, the leftover decomposes in our mouth causing the pH to go below 5.5. Thus, the bacteria present in our mouth release acids which when made in contact with the enamel (made of calcium hydroxyappetite, a crystalline form of "calcium phosphate" a basic salt), destroys the enamel. This is what leads to dental caries.

Adithya Dev A 4 years, 5 months ago

In tall plants, it is nearly impossible to bring water to the apical area through upward conduction by root pressure alone (it takes a long time). In such cases, transpiration plays the key role. As water is lost from the plant through transpiration especially during summers, naturally changes occur in the plant such that a particular form of suction force is produced which literally SUCKS the water up the xylem so that it reaches the topmost region. This is known as COHESIVE FORCE.
