Answer:
a) 1/64
Explanation:
<h3>The cross is: AaBbccDd x aaBbCcDd</h3>
If all genes are independent, we can analyze the cross of each gene to calculate the genotypic proportions in the offspring. Afterwords, we can use the Multiplication Rule of Probability to calculate the overall probability of having progeny of aabbCcDD genotype.
<h3><u>Aa x aa
</u></h3>
1/2 Aa
1/2 aa
<h3><u>Bb x Bb
</u></h3>
1/4 BB
2/4 Bb
1/4 bb
<h3><u>cc x Cc
</u></h3>
1/2 Cc
1/2 cc
<h3><u>Dd x Dd</u></h3>
1/4 DD
2/4 Dd
1/4 dd
The rule of multiplication states that for independent events, the probability of all of them occurring at the same time can be calculated by multiplying the probability of each of them.
Then, the probability of having offspring with the aabbCcDD genotype will be: 1/2 × 1/4 × 1/2 × 1/4 = 1/64
(C) earth's outer iron core
this is because iron is magnetic and therefore forms a strong magnetic field
The ocean waters at the equator are warm because they receive more of the sun rays than the waters at the at the poles. Therefore, the water in these regions is less dense than those at the poles. The oceans currents, moving towards the poles from the equator, move on the surface waters while those from the poles move on the ocean floor.
As the warm currents move to the poles and cool, they become more saline because they become more concentrated with salts –saturation point lowers with temperatures. At the poles, most of the salts in ejected from the waters as brine as the water sinks to the ocean floor due to density.
This movement of water currents in such circular motion forms the Thermohaline Circulation. Heat on the planet is distributed in this way.
Answer: This is true for all parts of the surface of the Earth including the land and the upper parts of the ocean. The four natural resources; soil/rock, air, water, sun; constitute the major components of the physical environment.
