Number of chromosomes?
Sex of individual?
Normal? Yes or no.
If abnormal, what chromosome pair?

Answers

Hey There!_____________________________________Answer:KAROTYPE:

This is the picture of karyotype. Karyotype is a collection of a Individuals chromosome. Like pairs are separately represented from the unlike pairs, It is generally used to study the chromosomes and the abnormalities found in the number of chromosomes.

_____________________________________CHROMOSOMAL NUMBER 18:

Every chromosomal pair seems fine, except the chromosomal pair number 18. Because as you ca see that it has 3 chromosomes instead of 2. This impairment in the chromosomal pair is called trisomy as it has 3 chromosomes.

_____________________________________TRISOMY 18:

Trisomy 18 is also called Edwards syndrome. It is a chromosomal condition associated with abnormalities in more than one part of the body. Individuals with trisomy 18 often mature slowly than normal fetus before birth and they have lower weight at the time of birth as compared to the other children.

_____________________________________Best Regards!'Borz'

There are 23 pairs of chromosomes in total, and the individual is male because it has one X and two Y chromosomes, but this individual is abnormal because of the trisomy in the 18th chromosome, as the 18th pair has three chromosomes.

What is the chromosomal abnormality?

The chromosomal abnormality is caused by the mutation in the chromosome number and includes either the deletion of the chromosome or the addition of the chromosome in a homologous pair. The chromosomal abnormality has many negative consequences as well, some extra copies in the sex chromosome pair cause infertility, etc., while deletion causes life-threatening conditions.

Hence, there are 23 pairs of chromosomes in total, and the individual is male because it has one X and two Y chromosomes, but this individual is abnormal because of the trisomy in the 18th chromosome, as the 18th pair has three chromosomes.

Answers

Answer:

Recent studies have shown that personality seems to be particularly malleable in children and adolescents; however individual differences in personality traits (such as, for example, temperament) are generally stable during adulthood .

Moreover, personality has shown to be quite stable during adulthood, regardless if the person is a woman or a man. For example, if a person was reserved and timid in high school, these traits remain relatively stable during adulthood. In general, with the age people becomes more emotionally stable, conscientious, and control better their impulses.

A student performs a diffusion lab using a starch/glucose solution, iodine solution, and dialysis tubing (cell membrane). The student waits 10 minutes before making observations. The student reports that iodine moved across the cell membrane. What observation helped the student draw their conclusion?

Answers

Answer:

Diffusion takes place in this process where iodine and glucose molecule diffuses through the dialysis tubing whereas the starch did not. Diffusion takes place on the basis of the size of the molecules.

Starch molecules are large in size whereas iodine and glucose are much smaller therefore they are able to diffuse. If both iodine and starch would have diffuses through the tubing the color would change into dark purple by mixing thee both molecules.
