Answer:
1/64
Explanation:
The following genotypes were crossed: AaBbCc X+Xr and AaBBcc X+Y
If we asume that the autosomal genes are in different chromosomes, then they will assort independently during meiosis and gametogenesis. In that case, we can use the Multiplication Rule of Probability to obtain the probability of having a specific genotype in the progeny.<u> This rule states that when two or more events are independent, the probability of all them happening at the same time will be the result of the multiplication of the individual probabilities of each event.</u>
<u />
We can separate each gene in the cross to determine the genotypic ratios in the offspring, and then multiply the probabilities of the aaBbCc X+X+ genotypes to obtain the overall probability of having progeny with that genotype.
<h3><u>Aa x Aa
</u></h3>
1/4 AA
2/4 Aa
1/4 aa
<h3><u>Bb x BB
</u></h3>
1/2 BB
1/2 Bb
<h3><u>Cc x cc
</u></h3>
1/2 Cc
1/2 cc
<h3><u>
X+Xr x X+Y</u></h3>
1/4 X+X+
1/4 X+Y
1/4 X+Xr
1/4 XrY
The probability of having offspring with the aaBbCc X+X+ genotype will be: 1/4 × 1/2 × 1/2 × 1/4 = 1/64
The gas pedal opens the throttle. This supplies air to the engine and fuel is metered into the air stream to provide a combustible mixture to the engine. If the throttle is close, I.e., you lift you foot, this process stops and the engine slows to an idle setting where enough fuel is provided to keep the engine turning over but not to move the car at any significant speed. When your cruising at a steady speed, even on a flat road, the engine turns over faster and requires enough fuel so that air resistance are overcome as well as internal friction losses in the engine.
<span>no because organisms such as humans are omnivores they can eat both meat and plants and may act as 1st,2nd or 3rd level heterotroph.</span>
We know that oil floats on water and do not mix
<span>
What happens to the oil when you first pour it in? It flows into the water, but then seperates.
Why does this happen? oil is lighter than water and the molecules of the oil are attracted to the other oil molecules, not water, the water molecules the same
What kinds of animals would be most affected by an oil spill at the beginning? animals that live their lives near the surface of the ocean. Why? because now the water that was clear and free-flowing is now dark and sticky. oil also changes the way how some animals survive so make their ways less effective. one example are birds like pelicans
Use a spoon to stir the oil for 30 seconds.
Answer the following questions:
What natural action stirs the real ocean? ocean currents caused by wind and the earth's roation
What happened to the oil? went back to the top
Even if you can’t see it, is all the oil still in your ocean? yes
Which animals in the ocean become affected after wave and current
action causes some of the oil to settle to the bottom, or be absorbed
into the water? bottom-feeders
Add a splash of dish detergent to the mixture and stir.
Answer the following questions:
What happened to the oil? it mixed with the water Is it all still in the ocean? yes
Sometimes cleanup efforts involve dumping a soap mixture over a spill area. Why is this done? to bond the oil to the detergent and the detergent to the water. so they can grab all the oil
What might be a negative effect of dumping the soap?</span> soap has chemicals that could upset the ballance of the ecosystem and kil some animals/plants
