Which test is carried out 15 to 20 weeks into a pregnancy, and allows the analysis of fetal cells that can identify a variety of genetic defects with nearly 100 percent accuracy?

Amniocentesis is the test.

Step-by-step explanation:

Given:

Which test is carried out 15 to 20 weeks into a pregnancy, and allows the analysis of fetal cells that can identify a variety of genetic defects with nearly 100 percent accuracy?

Now, to find the test.

Amniocentesis is the test which is carried out 15 to 20 weeks into a pregnancy, and allows the analysis of fetal cells that can identify a variety of genetic defects with nearly 100 percent accuracy.

In this medical procedure some little amount of amniotic fluid is sampled through insertion of needle in the uterus which contain fetal tissues. Then the Fetal DNA is examined. This can also be used to determine sex of the foetus. This medical procedure is carried when women are between 15 to 20 weeks gestation.

In some countries there are some restrictions as this may use for sex determination for example country like India.

Therefore, amniocentesis is the test.

62.5 paisa

step-by-step explanation:

4000*70 = 280000

280000-(2000*90) = 100000

4000-2400 = 1600

100000/1600 = 62.5

, and

for

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be
