Answer:
C
Explanation:
Acidic soils mean they have more of Al3+ and H+ ions which are acid forming cations. These cations make alkaline forming ions unavailable to plants as nutrients. When the pH of the soil is raised, the Al3+, Fe3+, and H+ are neutralized. The ions bind with –OH ions hence releasing the ions in the negatively-charged sites on the hummus to play a role in the nutrient exchange.
Answer:
Explanation:
Selection breeding is use to identify individual with good physical characteristics that can be used as parent in next generation. Brown, yellow, green grasshoppers are the distinct phenotypic characteristics of an individual hence selection will be individual base. Such that brown individual will be selected, green selected seperated and yellow will also selected. The organism that shows the best fits are often been selected depending on the objects of the selection
The height of the rider could be increased by the increase in force of water. The newton's third law says that every force has equal and opposite reactive force.
<h3>What is Newton's third law?</h3>
Newton's third law says that when two bodies interact, they apply equal and opposite force on each other.
In the jetpack rocket, the man goes higher due to the force applied by water in the down direction, and the man is going up according to the third law of Newton.
Thus, the height of the rider could be increased by the increase in force of water. The newton's third law says that every force has equal and opposite reactive force.

<span>Molecular clock is a scale which uses a technique whereby evolutionary time for different life forms is deduced from the mutation rate of biomolecules. Biomolecular data used for calculations in order to come up with the prehistoric time scale normally uses nucleotide sequences for DNA or amino acid sequences for proteins.
Hence, in order to develop a molecular clock, one would need: a sequence of molecules, the rate at which changes occur in a type of molecule and how much total change has occurred in a type of molecule from different species.</span>
