Erin is a 28-year-old professional woman who is 5 feet 8 inches tall and vigilantly maintains her weight at 118 pounds by following a lacto-ovo (non-fat milk and egg whites only) vegetarian diet that supplies approximately 1200 calories a day. With her understanding that protein should provide between 10 and 35 percent of her daily calories, she reasons that her daily intake of 40 grams of protein from milk, eggs, legumes, and nuts is adequate for her needs. She is concerned, however, that she has been sick more than usual and has experienced two stress fractures in her leg over the past three years while exercising. How many kcals per day should she take in for optimal energy intake?

1800 calories.

Explanation:

The balanced diet is the diet that contains the enough amount of carbohydrates, proteins, vitamin, fats, minerals and roughage. This balanced diet is important for all age groups.

According to the RDA (Recommended Dietary Allowance), the minimum calories that must be obtained by 28 years old woman is around 1600 clories per day. The intake of less than this amount of calories might cause fatigue, stress and other health related problems.

Thus, the answer is 1800 calories.

the correct answer is: b. pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction.  

because involves two organisms (parents) whose genetic material combines, sexual reproduction leads to genetic variation in new generations of offspring. the offspring is an unique organism, with new genome, more protected with the higher ability to adapted. this process is fundamental to evolution.

answer >   yes we do, women; have three holes, urethral opening(pee hole, vagina, and the women pee/girls pee out of the urethra like the men do; only they have a single opening to pee/ejaculate.   (sorry if i'm too forward with this, but this is for a biology class, isn't it? )

hope that !         : )
