Scatter Radiation is a type of secondary radiation that occurs when the useful beam intercepts any object, causing some x-rays to be scattered. During an x-ray or fluoroscopic exam the patient is the most significant source of scatter radiation.Scatter radiation occurs as a result of the targeted beam striking objects, such as the patient's body, and reflecting a more harmful secondary radiation in all directions. One method of reducing the medical staff's exposure to this harmful scatter radiation is the implementation Infab's new Scatter Armor Shields.
I hope this helped :)
Answer:
See explanation below
Explanation:
<em>Non-disjunction occur as a result of lack of separation of homologous chromosomes during meiosis. </em>
As a result, the gametes (the daughter cells formed) produced end up having extra or lesser chromosomes as compared to a normal gamete.
When a gamete with extra chromosome fertilizes a normal gamete, the resulting offspring will have an extra chromosome (trisomy condition).
On the other hand, when a gamete with one less chromosome than normal fertilizes a normal gamete, the resulting offspring will have one less chromosome than normal offspring (monosomy condition).
Assuming a chromosome with Aa gene undergoes non disjunction during meiosis, the resulting gametes either contain both A and a chromosome or contain no chromosome at all.
If Aa gamete is fertilized by a normal haploid sperm (a), the resulting zygote will have the genotype Aaa.
If a gamete with no chromosome at all fertilizes a normal haploid sperm, the resulting offspring will have the genotype a.

B. bacterial enzymes that destroy phage DNA.
Explanation:
Answer: Insects create the biological foundation for all terrestrial ecosystems. They cycle nutrients, pollinate plants, disperse seeds, maintain soil structure and fertility, control populations of other organisms, and provide a major food source for other taxa
Facts about insects: Insects are pancrustacean hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body, three pairs of jointed legs, compound eyes and one pair of antennae.
