D. One sex has a higher chance to inherit it than the other (male).
These can be either recessive or dominant. We usually think more of the recessive traits like color blindness and hemophilia but dominant sex-linked traits also exist (fragile X).
Acute HIV infection is the first phase of HIV infection. The early HIV test can detect HIV during the acute HIV phase. The best test for detecting HIV infection is the early HIV test (also known as NAAT/RNA testing)

<span>The correct answer to this question is a line graph. If Rob needs to create a graph that is able to display the combination of two different values - in this case, level to which the salt has dissolved and time taken - and he needs to have more than one result included, then a line graph is the way to present this.</span>
<u>The heart is a cone-shaped muscular organ located within the mediastinum of the thorax.</u>
The mediastinum is the space lined with membranous tissue between the lungs. The mediastinum contains not only the heart but also the great vessels (pulmonary artery, aorta, pulmonary veins, and the superior and inferior vena cava), as well as parts of the esophagus and the trachea.
<span><u>Its apex rests on the </u><u>diaphragm</u><u> and its superior margin lies at the level of the </u><u>2nd</u><u> rib.</u>
</span>
The apex of the heart is the conical area created by the confluence of the ventricles, but mainly by the left ventricle. It rests on the diaphragm. The superior margin of the heart, also known as the base, lies at the level of the second rib.
<span><u>Approximately two-thirds of the heart mass is seen to the left of the </u><u>midsternal border</u><span><u>.</u>
</span>
This is because to the left of the midsternal border lies the left ventricle which comprises most of the heart mass as the left ventricle is the one responsible for pumping blood throughout the systemic circulation and significant pressure should be overcame; resulting to the physiologic hypertrophy of the left ventricle.
</span><span><u>The heart is enclosed in a serosal sac called the </u><u>pericardium</u><u>. The loosely fitting double outer layer consists of the outermost fibrous pericardium, lined by the parietal layer of the serous pericardium.</u></span>
The pericardium is one of three layers of the heart (other ones being the myocardium and the endocardium); and is the outer layer of the heart. The pericardium is composed of two tissues, the fibrous pericardium and the serous pericardium. The pericardium functions to lubricate the movement of the heart by the action of the pericardial fluid.
<span><u>The heart has </u><u>four</u><u> chambers. R</u></span><span><u>elative to the roles of these chambers, the </u><u>atria </u><u>are the receiving chambers, </u></span><span><u>whereas the </u><u>ventricles </u><u>are the discharging chambers.</u>
</span>
The four chambers of the heart are namely the right atrium, right ventricle, left atrium, and the left ventricle. Venous blood goes to the right atrium via the vena cavas then to the right ventricle via the tricuspid valve; then to the pulmonary circulation via the pulmonary artery where it will be oxygenated. From the pulmonary circulation, the left atrium will receive the oxygenated blood via the pulmonary veins then to the left ventricle via the mitral valve where it will be pumped to the systemic circulation via the aorta.
Diseases have multiple ways of infiltrating your body. Diseases can be transported through blood, air, and physical touch. Once the disease has infiltrated the body, it can spread through out the body in many ways. One of which is by feeding off of other cells energy and reproducing. The pathogens travel through the blood and irritate cells. The irritation of cells can cause the body to consume more energy, to repair the damage. This causes symptoms like tiredness, regurgitation, and sometimes in extreme cases, death.
