The answer is <span>B. fibrin.
Through the process of elimination: thrombin and thromboplastin are enzymes so these choices are incorrect. Platelets are actually cells, which leaves us B. fibrin as the correct choice.
</span>A fibrinogen is a protein involved in the formation of blood clot. It is converted by enzyme thrombin into fibrin during blood clot formation.
Answer:
The pulmonary artery carries oxygenated blood from the right ventricle to the lungs. The blood here passes through capillaries adjacent to alveolar and becomes oxygenated as part of the process of respiration. In contrast to the pulmonary arteries, the bronchial arteries supply nutrition to the lungs themselves.
Explanation:
There are multiple reasons why and MRI scan as a diagnostic tool can be considered inappropriate. The primary reason other diagnostics are used over MRI is because of cost-effectivity. The MRI scan is considerably more expensive compared to x-rays and CT scans. It would be inappropriate to ask for an MRI when the symptoms point to a simple bone fracture of the leg for example. An x-ray can give you the same amount of information in this regard without the huge cost of an MRI.
Another example would be if the patient is claustrophobic. Taking an MRI scan takes a long time and it would involve inserting the patient in a coffin-like machine. Getting an image would be impossible because the patient would need to hold still for a span of 40 minutes to 1 hour.
The correct answer is A. Thyroid
Explanation:
In biology, a gland refers to a type of structure composed by cells whose main function is to synthesize substances especially hormones. This includes the thymus gland that is composed of two lobes and is located near the heart; the anterior/posterior pituitary gland that is located at the base of the brain and it is one of the smallest glands; the pancreas that is located in the abdomen and the thyroid that as the thymos is composed of two lobes, secrets different hormones and it is located in the neck/throat. Considering this, the gland described is the Thyroid because this is the only one located in the throat and also this is composed of two loves.
Answer:
O. Wave A has a higher frequency because it has a shorter wavelength.
Explanation:
Wavelength refers to the distance between two crests while frequency refers to the number of waves passes through a specific point per second. Frequency and wavelength are inversely proportional to each other. Inversely proportional means if one increases, the other decreases and vice versa. If the frequency of the wave is higher so its wavelength becomes shorter and if the frequency of the wave is shorter so its wavelength is higher.
