The heat of fusion of the ice is the amount of energy that is required in order to melt one gram of ice. In this item, in order to solve for the heat of fusion, we simply have to divide the given energy by the mass.
heat of fusion = 16650 J / 50 g = 333 J/g
Thus, the heat of fusion of the ice is 333 J/g.
The correct option is D.
During the process of photosynthesis, carbon dioxide and water react together in the presence of sunlight energy to form glucose and oxygen. Glucose and oxygen are the product of photosynthesis. The chemical formula for glucose is C6H12O6 and that of oxygen is O2.
<span><u>The answer is A. 72.25 percent.</u>
The Hardy-Weinberg principle can be used:</span>
<em>p² + 2pq + q² = 1</em> and <em>p + q = 1</em>
where <em>p</em> and <em>q</em> are the frequencies of
the alleles, and <em>p²</em>, <em>q²</em> and <em>2pq </em>are the
frequencies of the genotypes.
<span>The <em>r</em> allele (<em>q</em>) is found in 15% of the population:
q = 15% = 15/100
Thus, q = </span><span>0.15
To calculate the <em>R</em> allele frequency (<em>p</em>), the formula p + q = 1 is
used:
If p + q = 1, then p = 1 - q
p = 1 - 0.15
Thus, </span><span>p = 0.85
Knowing the frequency of the <em>R</em> allele (<em>p</em>), it is easy to determine the
frequency of the RR genotype (p²):
p² = 0.85² = 0.7225
Expressed in percentage, p² = 72.25%.</span>
We support each of the following correct statements with appropriate justification, indicating why or how each statement is correct.
<h3>3. A radiograph of a horse's frontal fetlock joint is called a dorsopalmar (PD) view.</h3>
Dorsopalmar (PD) view The horse's frontal fetlock joint demonstrates dislocation of the antebrachiocarpal joint with soft tissue swelling around the carpal joint
<h3>5. When performing surgery on the digestive system, we must ensure that the suture is well closed. </h3>
Yes. Endoscopic suturing is a procedure performed 100% by endoscopy, a procedure that inserts a flexible tube through the patient's oral cavity and reaches the structures of the digestive system. It is a non-invasive, safe process that does not require any cutting.
<h3>6. Oblique positions are sometimes used in radiographs.</h3>
Yes. Right and Left Anterior Oblique Positions (RAO and LAO) These terms refer to oblique positions in which the right or left anterior side of the body is close to the RI, and can be in an upright or recumbent position.
