Answer:
<em>His decreased residual volume and decreased lung compliance contribute to his altered ventilation.
</em>
Explanation:
Pneumoconioses are distinguished by reduced residual volume and impaired compliance with the lungs.
Pneumoconiosis involves asbestosis, silicosis, and the pneumoconiosis (CWP) of coal workers.
The most prevalent mineral dusts proven to cause pneumoconiosis in the workplace are asbestos, silica (rock and sand dust), and coal dust.
Cough and shortness of breath are by far the most common symptoms of pneumoconiosis. The threat is usually greater when people are exposed to high levels and/or long periods of time from mineral dusts.
One risk factor is the insufficient or inconsistent usage of personal protective equipment (PPE) such as respirators (specially designed breathing masks), as avoiding inhalation of dusts would also avoid pneumoconiosis.
Answer:
between-subjects design
Explanation:
According to my research on different experimental designs, I can say that based on the information provided within the question the best way to make sure that the internal validity will not be influenced by an outside event is to switch to a between-subjects design. This type of design is an experiment design that has two or more groups of subjects each being tested by a different testing factor simultaneously. Since they are done simultaneously it significantly reduces outside influence.

Answer:c or d
Explanation:
Sometimes it’s in your genetics and other times it’s your lifestyle.
<span>The answer is extracapsular cataract extraction (ECCE). It is
a kind of eye surgery in which the lens of the eyes are removed, leaving the
elastic capsule covering the lens which is left partially attached to let the
implantation of an intraocular lens (IOL). This approach is compared with
intracapsular cataract extraction (ICCE), an older procedure in which the
surgeon detached the complete lens within its capsule and left the eye aphakic
(without a lens). The patient's vision was corrected after intracapsular
extraction by extremely thick eyeglasses or by contact lenses. There are two
major types of ECCE: manual expression, in which the lens is removed through a slit
made in the cornea or the sclera of the eye; and phacoemulsification, in which
the lens is shattered into fragments inside the capsule by ultrasound energy
and removed by aspiration.</span>
