Your answer is C. Abrasion. Abrasion is a mechanical weathering, which uses physical forces to break down rocks without changing the chemical composition. The other answers are examples of chemical weathering.
Organs join together to form a system. Such as the respiratory system
Molarity =

Moles of Caffeine = Mass of Caffeine/Molar Mass
Mass = 100 mg = 0.1 g
Molar Mass = 196 g/mole
Moles of Caffeine in one cup = 0.1/196 moles
= 5.102 * 10^-4 moles
If one cup of coffee is ingested (A typical adult contains about 40 liters of water),
Molarity of caffeine = [(5.1 * 10^-4)/ 40] M
= 0.012755 mM
The toxic molarity of caffeine in the body 10mM
How many cups will be toxic?
= Toxic Molarity/ Molarity of 1 cup
= 10/ 0.012755
= 784
In other words, you would have to drink
784 cups of coffee to reach the dose required to interfere with the DNA replication checkpoint mechanism.
Answer 1-
<u>Mendelian
</u>
The different allelic combinations are made by the process of mendelian inheritance. This happens before cell division.
Answer 2-
<u>25%
</u>
In a monohybrid cross, there are four boxes, and thus each box denotes 25% share.
Answer 3-
<u>75%
</u>
The cross between Pp and Pp will look like the image shared below. Here, PP and Pp will show dominant trait. Since, it is 3 out of 4 boxes, it will be 75%.
Answer 4-
<u>100
</u>
The punnett square for this cross RR and WW is shown below. Since all the offsprings are RW, therefore it is 100% pink flowers.
Answer 5-
<u>Tt
</u>
Since it is a case of dihybrid cross, the gametes formed from TtHh would contain both the alleles. The possible gametes would be TH, Th, tH and th.
Answer 6-
<u>aabb
</u>
In any dihybrid cross with dominant alleles, the probability of getting aabb would be the least.
Answer 7-
<u>56%
</u>
In a cross AaBb and AaBb, the probability of getting both dominant traits- round and yellow, would be 56%
