Answer:
Bet
Explanation:
1. The radiaton from the X-ray waves can be harmful 
2. Lack of resources comes on part of both the provider as well as the patient as the provider may not necessarily have the appropriate equipment or updated technology yet to detect such conditions such as in smaller town hospitals or even the patient may not have the financial or transportation resources in order to obtain these. Another one but while being a little subjective I think could even be a lack of knowledge on both of our parts as well as healthcare providers don't always have all the answers to everything let alone the resources as mentioned earlier or even perhaps the patient doesn't know the earlier signs and symptoms of certain cancers and even more so some cancers are VERY difficult to detect, especially until its too late. 
3. X-ray imaging creates pictures of the inside of your body. The images show the parts of your body in different shades of black and white. This is because different tissues absorb different amounts of radiation. Calcium in bones absorbs x-rays the most, so bones look white
4. An X-Ray will be neccesary, ultrasounds exam organs while x-rays examine bones
 
        
             
        
        
        
Answer:
(a) crossing over:  Meiosis I, Recombination  
(b) chromatids separate at their centromeres and migrate to opposite poles: Meiosis II, Anaphase II
(c) chromosomes become aligned in pairs at the equator: Meiosis II, Metaphase II
Explanation:
Homologous recombination is a type of genetic recombination that occurs during meiosis (formation of ovum and sperm cells). The paired chromosomes of the male and female parents are aligned so that similar DNA sequences intersect. This crossing over produces an exchange of genetic material, which is an important cause of the genetic variability observed in the offspring.
Meiosis II: Anaphase II. The centromeres separate and the daughter chromatids - now individual chromosomes - move to the opposite poles of the cell. The centromeres separate, and the two chromatids of each chromosome move toward the opposite poles in the spindle.
Meiosis II: Metaphase II. Chromosomes are accommodated in the equatorial plate of metaphase, similar to what happens in mitosis. They are attached to the already fully formed meiotic spindle. Each chromosome is aligned in the equatorial plate of the metaphase, as it happens in mitosis.
