Answer:
Trisomy 21 would show presence of an extra copy of chromosome 21 in a karyotype
Explanation:
Humans are diploid organisms, having 23 pairs of chromosomes (46 chromosomes in each cell. Trisomy represents a chromosomal disorder, with presence of an additional chromosome (total 47 chromosomes, instead of 46).
Down syndrome is a genetic disorder caused by trisomy of chromosome 21. Karyotype is used to represent appearance and number of chromosomes present in nucleus of a cell.
Thus, in karyotype trisomy 21 there would be an additional copy of chromosome 21. Diagram of karyotype trisomy 21 is attached with answer.
A karyotype is the number and appearance of chromosomes in the nucleus of an eukaryotic cell.

Answer:
Retro Active Interference
Explanation:
This confusion of Rick's memory for his address for the previous one is attributed to Retro active interference.
The phenomena where recently learned memory of a person meddles with and blocks the review of previously learned data or memory is referred to as Retro active Interference.
This happens when the underlying demonstration of reviewing explicit data meddles with the recovery of the first data.
Answer:
Carbohydrate = 57.023g
Fats = 20.736g
Proteins = 25.919g
Explanation:
According to this question, Valerie is planning to eat at dinner meal that has a total of 800 Calories.
- 55% calories come from carbohydrate i.e. 55/100 × 800 = 440 calories
- 20% calories come from fat i.e. 20/100 × 800 = 160 calories
- 25% calories come from proteins i.e. 25/100 × 800 = 200 calories
Since 7.716 calories = 1g
1. Amount of carbohydrates in gram = 440/7.716 = 57.023g
2. Amount of fats in gram = 160/7.716 = 20.736g
3. Amount of proteins in gram = 200/7.716 = 25.919g
