Starches
-These provide proteins and sugars.
Animal Proteins
-We can obtain proteins from foods, which have an animal origin.
Vegetable Oils
-Provide the lipids.
Fiber-Which comes from vegetables is also a sugar it is necessary for helping the food to pass through the intestine.
Summarize the changes over time.
-A new born baby has to consume 650 calories andthe babies consume 200 calories more from 1 to 3 years we have to consume 1,300 calories from 4 to 6 1,800 calories, from 7 to 10 2,000 calories.
Why does our body store lipids as a medium andlong-term energy reserve rather than sugars?
-Because lipids contains for more energy than sugars.
What happens four diets gives up more energy than we consume everyday?
-It will be accumulated as fatcausing obesity.
Why do we consume energy even when we ate at rest?
-Because our organs still working.
What are all reservation techniques base on do they al kill microorganism?
-Eliminatingmicroorganism or stop their action; not all are kill.
Which is the oldest method of food preservation, eg?
-Drying, salting and smoking, eg: cold, hem and salmon.
Can refrigeration preservefood indefinitely? Why not?
-No, it only slows the action, freezing is more effective cause it stops bacteria almost complete.
Preservatives.
-Additives that make food last longer.
Function ofpreservatives.
-Help food last longer than usual.
Summarize the processes involved in reproduction
-Female and make gametes unify, this is called fertilization and forms a zygote, then the embryois formed, after months the fetus becomes the new baby.
Female reproductive system
Ovaries.
-To make ova
Prostate.
-To make prostate fluid
Uterus.
-To house the embryo.
Seminal.
-Tomake spermatozoids.
Testicles.
-To make spermatozoids.
Vagina.
-To communicate the uterus with the exterior.
Illness
-Abnormal process, which alters, modifies the activity of the...
