Which statement best explains why a karyotype can be used as a scientific report? 1: a karyotype is created and used to identify possible chromosomal defects. 2: a karyotype can be used for reporting medical concerns and possible genetic disorders.  3: a karyotype can assist families with medical issues that may arise from chromosomal abnormalities.  4: a karyotype is formatted as a long document that has a vast number of scientific references.

the answer for this question is A

1: A karyotype is created and used to identify possible chromosomal defects.

Explanation:

A karyotype is the observed characteristics (number, type, shape, position etc.) of the chromosomes of an individual or species within the nucleus of the cell (mainly eukaryotic). Karyotype tests are performed to show if an individual’s chromosomes are normal or not. The chromosomes (especially those in the white blood cells) are usually isolated, stained, and examined under the microscope. This detect if there is an abnormal chromosome, an extra chromosome or an incomplete chromosome. A karyotype can be used as a scientific report because possible chromosomal defects such as Down syndrome (trisomy 21), Klinefelter syndrome, Edwards syndrome and Turner syndrome can be identified using the Karyotype tests.

the answer is trees if i'm not mistaken

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.
