What are two Laboratory Animal Allergy prevention components that an effective occupational health program should address <u>Work practice and personnel risk assessment</u>
<h3>What is
Animal Allergy?</h3>
Animal allergies are defined in medicine as hypersensitivity to particular compounds made by animals, such as the proteins in animal saliva and hair. It's a typical kind of allergy. Itchy skin, nasal congestion, itchy nose, sneezing, a persistent sore throat or itchy throat, swollen, red, itchy, and watery eyes, coughing, asthma, or a rash on the face or chest can all be signs of an allergic reaction to animals. An overly sensitive immune system that results in an improperly focused immune response is what causes allergies. Normally, the immune system defends the body from dangerous agents like bacteria and viruses. When the immune system responds to substances (allergens) that are typically safe and do not elicit an immunological response in most persons, allergy arises.

Answer:
C. Macrophages
Explanation:
Macrophages are derived from monocytes of the bone marrow. They migrate to connective tissue and are in charge of phagocytosis of foreign particles. They also participate in the enhancement of inmunological activities of lymphocytes. Macrophages can be found in infection sites, since they detect, phagocytose and destroy bacteria and other harmful organisms.
Answer:
Standard <u>anatomical
</u> position is the agreed-upon reference for body position when studying anatomy (option 2).
Explanation:
Anatomical position consists of the placement of the human body for its anatomical study, following certain norms established and accepted by convention.
- <em>The body is observed from its front face.
</em>
- <em>The members must be extended, showing their ventral surface and with a slight separation from the rest of the body.
</em>
- <em>The hands show the palms, while the feet are hyperextended showing their backs.
</em>
This position is useful to provide the description of any area of the body in a specific posture, and that can be understood even by those who do not observe.
The other options are not correct because:
<em> 1) </em><u><em>Histological</em></u><em>, refers to the study of cells and tissues.
</em>
<em> 3) </em><u><em>Superior</em></u><em>, is a directional term, indicating something located at the top of the body or closer to the head.
</em>
<em> 4) </em><u><em>Mnemonic</em></u><em> refers to the association of words used to remember names or lists of names.</em>
The acrosome contains enzymes that break down the outer membrane of the egg cell, letting the sperm fertilize the egg.
What is an acrosome?
An acrosome is a unique membranous organelle that is located over the anterior part of the sperm nucleus. It is highly conserved throughout evolution.
This acrosome contains a number of hydrolytic enzymes that help the sperm penetrate the egg's coats, when secreted.
The proteolytic enzymes such as hyaluronidase and acrosin are what help the sperm penetrate the eggs coat.
Acrosome comes from the Golgi complex of the spermatid. It consists of a protein matrix core and numerous hydrolytic and glycolytic enzymes, which are necessary for fertilization.
Therefore, the acrosome contains enzymes that break down the outer membrane of the egg cell, letting the sperm fertilize the egg.

Answer: (A)True
Explanation:
People who have problems controlling their urine or bowels (aka incontinence) are at risk for skin problems.
Skin areas most affected are near the buttocks, hips, genitals, and between the pelvis and rectum (perineum).
