<span>F- allele for freckles
f- </span><span>allele without freckles
1) The man is heterozygote and has freckles, its indicating that the allele for freckles is dominant.
A cross between him and a woman who is also </span><span>heterozygote: Ff x Ff
it would result in the following probabilities:
- 1/4 - homozygote with freckles: FF
- 2/4 - </span><span>heterozygote with freckles: Ff
- 1/4- </span><span>homozygote without freckles:ff
Their son would have a probability of 75% of being born with freckles.
2) The cross resulted in this probabilities:
</span><span><span>- 1/4 - homozygote with freckles: FF
- 2/4 - </span><span>heterozygote with freckles: Ff
- 1/4- </span><span>homozygote without freckles:ff
So, the chance of being born heterozygote for this gene is 2/4, which is the same as half (50%).

<span>The correct answer is b: Coenzyme A.</span>
During the process of pyruvate oxidation, acetyl CoA molecule is produced. Pyruvate oxidation is the link between glycolysis and Krebs cycle and it converts pyruvate (three-carbon molecule) into acetyl-CoA ( two-carbon molecule attached to Coenzyme A). NADH is produced and one CO2 released. AcetylCoA is the substrate for the next stage of cellular respiration, citric acid cycle.
Answer;
-Frames
Much like signs and symbols, frames appear natural and go largely unquestioned.
Explanation;
Framing involves the presentation and communication of a message in a particular way that influences our perception of it; frames act like signs/symbols in semiotics (once accepted, they appear natural and go largely unquestioned); also shapes our perceptions of people, places, issues, and events; veteran's "rights" versus "benefits" provide an example of this.
The answer is a. the ureters. The ureter is a tube that
carries urine from the kidney to the urinary bladder. There are two ureters, the
upper half of the ureter is located in the abdomen and the lower half is
located in the pelvic area. One attached to each kidney.
Formation of rust and the formation of cottage cheese both involve chemical reactions. Rust is chemically referred to as hydrated Iron (ii) oxide formed by the reactions between iron, water and oxygen. Cheese on other hand is formed by the reaction called fermentation.
