Assume that you work in criminal investigation unit and were called for an incident that involved someone who was shot. You arri

ved to the scene to see a dead person in his 50s and no other evidences rather than a small piece of clothing with blood on it. You collected the blood and went to the lab. The Investigation lead to four suspects that happened to be either close to the place of incident or had problems with the victim. You checked the blood type of that blood and it was (O). When you did blood typing for the four suspects, the results came out as the followings: jacks blood reacted only to A, Sams blood reacted to both A and B, Nathans blood reacted only to B, and Johns blood didnt react to either A or B. Which one of the four is the person of interest (suspect) based on the blood typing reaction?

Answer: Of the four suspects, JOHN is the person of interest

Explanation:

Since the blood collected from the crime scene was TYPE O, and TYPE O blood DO NOT react to either BLOOD TYPE A or B due to the fact that:

- it do not have antigen A

- it do not have antigen B

JOHN'S BLOOD type is the SAME as that collected from the crime scene. Thus, of the four suspects, JOHN is the person of interest

How is it possible for one twin to get skin cancer but the other one doesn´t
tia_tia [17]

Looking at most newborn twins squirm contentedly in their cribs, you'd never guess that some were recently in peril. That's because carrying multiples raises the risks that a woman can suffer complications before she actually delivers.

Many twins are miscarried early in the pregnancy, often before a woman even knows she's pregnant. As reported in the International Journal of Fertility, only about one in eight embryos that starts as a twin is born as a twin. If they do survive, twins are usually born healthy. However, they are still more likely than other babies to have birth defects or to be born prematurely or underweight.

Carrying twins can be hard on you, too. You'll be more likely to develop pregnancy-related high blood pressure or diabetes. And there's a greater likelihood you will have a cesarean section when you deliver.

If you're carrying twins, some simple lifestyle changes and good prenatal care may help you reduce the likelihood of the following complications.

Low birth weight

Because they have to share nutrients and living space, newborn twins tend to be smaller than single babies. Even full-term twins often weigh less than 5-1/2 pounds each, making them vulnerable to a variety of health problems. You can help your babies reach a healthy size by making sure you put on enough weight during pregnancy. Try to eat 300 calories more each day than you would if you had a single baby (about 2,700 calories in total). If you had a healthy weight before pregnancy, you should aim to put on about 35 or 45 pounds.

Unequal size

Twins don't always share equally. In roughly 30 percent all twin births, one baby will be larger than the other. Some studies suggest that if one of your babies is at least 25 percent heavier than the other, one or both of them may be more likely to have breathing problems or need intensive care. Your doctor will track the growth of both your babies throughout your pregnancy. The first signs of unequal growth usually appear in the third trimester.

Twin transfusion syndrome

Twin transfusion syndrome poses a dangerous threat to identical twins who share a single placenta. It's normal for such twins to exchange blood during a pregnancy. But in about 20 percent of cases, one twin starts pumping large amounts of blood to the other twin, putting both of them at risk. In severe cases, the twin receiving the extra blood may develop heart failure while the other twin becomes dangerously anemic. Early diagnosis and treatment can slow the abnormal blood flow and lower the risk of complications.

Birth defects

Birth defects are common in twins, especially identical twins. Taking folic acid before and during pregnancy can help prevent neural tube defects. As reported in the medical journal The Lancet, however, about 10 percent of all identical twins are born with a birth defect such as a heart problem, a shortened limb, a club foot, or a dislocated hip (the conditions listed are linked to having less space in the uterus and would not be affected by folic acid.) Most of these conditions are treatable, however.

Risks to the mother

Your doctor will check you regularly throughout the pregnancy for signs of high blood pressure or diabetes. When detected early, both of these conditions can be controlled before they have a chance to threaten your pregnancy.

Special care

Carrying twins means you'll probably get extra attention from your doctor throughout your pregnancy. The doctor may suggest cutting back on activities between the 20th and 30th week of pregnancy, even if you haven't had any signs of labor. Many physicians also recommend an extra monitoring check on the babies' heart rate and movement, such as an ultrasound or nonstress test. A biophysical profile, which checks on heart rate, movement, and the amount of amniotic fluid in your body, might also be indicated. If you do go into labor prematurely, your doctor may suggest drugs to stop the labor or use corticosteroids to speed up the development of the babies' lungs.

It's possible that you may be able to deliver twins vaginally. But if the labor is difficult, the birth canal is too narrow, or one or both of the infants is in the breech position, you may have to undergo a c-section, in which the babies are delivered through an incision in your uterus. Talk to your doctor about what you can do to prepare for delivery.

Twins are a special challenge, both before birth and after. For now, your job is to stay healthy and get top-quality prenatal care. Two important people are counting on you.

Does this help lol :D
