The odds are astronomical for a father with AB(IV) to have an O(I) child. The only possible way for this phenomenon to occur is if there was a nondisjunction in the ovogenesis for the 9th chromosome and the father also had a nondisjunction for the same chromosome(A sperm cell with no 9th chromosome fertilized an ovum with two 9 chromosomes).
A person with AB cannot donate to a person with O because the receiver has antibodies(alpha and beta) that bind to the antigens on the AB blood cells, causing death.
The energy produced from flow of water or "Hydro-power" is different to energy produced from iron, petroleum and coal as it is a clean and renewable form of energy. Hydro-power is derived from the kinetic energy of the natural flow of water like in the case of a water mill whereas the other forms listed require combustion of the fuel source that produces harmful gases leaving a negative impact on the environment. Also, hydro-power is one of the cheapest forms of energy production.
However, it should be noted that large-scale production of electrical energy from flowing water known as "Hydroelectric Power" uses man-made dams to store water in lakes as a source of potential energy. These dams can also have a negative impact on the environment as the natural flow of water is restricted. Some scientists also suggest that the construction of a dam leads to an increase in the number of earthquakes in and around the area of construction.
Here's a chart. Not sure what your choices are though.
Answer:
The correct answer is - D) 1000x.
Explanation:
pH is a logarithmic scale, 1 reading change leads to the results in ten-fold in the
H+ concentration in acidity/basicity. The more H
+ ions found in solution, the more acidic the substance is as acids donate H
+ ions.
You can calculate the concentration of H
+ from the pH and the equation

Answer:
A plant with large number of leaves could be danger of losing too much water.
Explanation:
Transpiration is a process that occur in plants which deals with the removal of water from the stomata present in the upper surface of leaves.
The rate of transpiration is directly proportion to the number of leaves present in a plant.
The presence of large number of leaves in a plant increases the transpiration rate of the later that is associated will losing too much water from the plant body.
