Explanation:

Down syndrome is an abnormality that occurs on chromosomes 21, it occurs because chromosomes 21 cannot be separated in meiosis, the pair of chromosomes 21 do not separate and go together to one of the daughter cells. In this way, the oocyte or the resulting sperm will have 24 chromosomes instead of 23. When in conception that oocyte or sperm joins the germ cell of its partner that contributes the 23 chromosomes, the total sum of chromosomes that will have the first cell of the new conceived being will be 47.

HELP PLEASE WILL GIVE BRAINLIEST!!!

1) 5% of saturated fat in one serving

2) 2 grams of dietary fibre

3) 750 calories

4) 9%

5) no

Explanation:

From the chart it is given that 1 serving gives 250 calories of energy while 1 container has 3 servings.

The dietary fibre in 250 calorie serving is 2 grams so on consuming 1 serving you get 2 grams of dietary fibre. It provides bulk to the roughage.

The entire container will give

3*250

= 750 calories in entire container.

If entire container consumed then ( 2grams amounts to 3%)

so three servings, 3*3

      = 9%

No vitamin C is found in the serving.
