Answer:
The answer to this question would be True.
Explanation:
The first time an allergen is introduced into your immune system, it triggers a response to create antibodies against the allergen. Only subsequent exposure to the allergen triggers anaphylaxis.

Penicillin [antibiotic] was widely used to:
B) treat soldiers during World War 2 (1940s-current)
*smallpox is a virus and not affected by antibiotics
*diabetes is not an infection, therefore antibiotics won't play a role
*plague and middle ages are CENTURIES before discovery of antibiotics
"The gradual and long-term removal of fine-grated particles like dust and sand, leaving behind bigger fragments".
Hello,
Well, the body needs vitamins/nutrients to thrive.So this can affect his chemical balance of his brain, which can result in depression/schizophrenia and things like eating disorders. Cutting fats might also result in overeating carbs and protein, which leads to an overbalance of nutrients. Which means that not getting enough fat can result in bad bone growth.Have an awesome day!
Mitotic spindle forms and the nuclear envelope fragments at the prophase stage of mitosis.
<h3>What are the stages of mitosis?</h3>
Mitosis has 4 main stages that are more or less in a continuous spectrum. These stages are:
- Prophase
- Metaphase
- Anaphase
- Telophase
The prophase stage is characterized by the dissolution of the nuclear envelope, the condensation of chromatin materials, and the onset of spindle formation.
The metaphase stage is characterized by the alignment of chromosomes at the equator and the engagement of each chromosome by spindle fibers at the centromere.
The separation of sister chromatids characterizes the anaphase through the shortening of the spindle fibers from the opposite ends of the cell.
The telophase is characterized by the completion of the migration of sister chromatids to the poles.
Thus, the mitotic spindle forms and the nuclear envelope fragments at the prophase stage of mitosis.
