Answer:
50% for sons 0%for daughters
Explanation:
the genotype of the mother is X⁻X
the genotype of the father is XY
the gametes from the mother are X⁻ andX
the gametes from the father are X and Y
to find the chance we make a Punnet square and cross each gamete
1 of the 2 males has the gene for colorblindness so there is a 50% chance that the son will be colorblind
1 of the 2 daughters has the gene for cloroblindness but only in one exemplary so the chance is 0%
<span>The nucleolus is the structure within the nucleus of eukaryotic cells. It consists of RNA, DNA, and proteins. The nucleolus is involved in ribosome biogenesis which results in the synthesis of ribosomes. Ribosomal RNA (rRNA) is transcribed from DNA in the nucleolus. rRNA is processed into three mature RNAs and together with proteins form ribosomal subunits. After subunits form the ribosomes, they are transported out of the nucleus to the cytoplasm where they take place in translation.</span>
Answer:
Galileo performed a famous experiment where he used a ball rolling on a ramp (inclined plane) to study the motion of objects under the influence of gravity. The ramp allowed him to make more precise measurements because the ball moved more slowly along the ramp than if it were simply dropped. Galileo discovered through this experiment that the objects fell with the same acceleration, proving his prediction true, while at the same time disproving Aristotle's theory of gravity (which states that objects fall at speed proportional to their mass). Galileo's conclusion from this thought experiment was that no force is needed to keep an object moving with constant velocity. Newton took this as his first law of motion. One result of the experiment surprised Galileo, and one surprises us. Galileo found that the heavy ball hit the ground first, but only by a little bit. Except for a small difference caused by air resistance, both balls reached nearly the same speed. And that surprised him. According to history, Galileo’s experiment on falling bodies largely contributed to Isaac Newton’s Law of Gravity. In Galileo’s experiment, he is said to have dropped balls from the Leaning Tower of Pisa. The balls were made of the same material but had different masses. Galileo set out to prove that the time it took for these objects to reach the ground would be the same. Galileo proved that objects reached the ground at the same time.
Explanation:
A P E X
<u>Answer</u>: B: the sequence of nucleotides in the DNA
<u>Explanation</u>:
Although there are only four nucleotides composing all DNA on Earth, the different order in which they are arranged will specify for different genes. The number of these genes and which of them are active, is what makes individuals unique.
