tag me if u get the answer m not good at this reproduction in plants

For artificial selection we can use sugar cane. A plant with high sugar content is bred with one which is resistant to diseases. Hybridisation results and the process is repeated over generations, with the traits passed down to offsprings. A time will arrive when a homologous is produced with both of those traits, and its inbred among itself or something :S I'm nor sure how to elaborate on this, or explain it in a 6 marked question. I'm not even sure if these are the correct answers but this is what I would write :/

dietary requirements include more water, cx of urea from the fetus can be excessive for the woman's kidneys to deal with,,,excess proteins to help the fetus grow..more carbohydrates to help provide the woman with energy she needs to move around with a larger body.....diet rich in minerals/vitamins(fruits) diet rich in folic acid, especially when the spinal cord of the fetus is under development....tag me if u get any other answer..

[Anees2rehman]

Advantages of breat milk.
It contains mothers antibodies.
It is free of cost.
If the bottled milk is not kept secure, bacteria may invade it which may result in the baby going I'll, while mothers milk is sterile.
It creates a emotional attachment between the mother and he baby.

[Anees2rehman]

Fats get emulsified in the duodonem by the bile coming from the gall bladder. Complete digestion occurs in the small intestine e.g the ileum by the cells surrounding the villi.
By the enzyme called lipase which acts on the emulsified fats to convert them to fatty acis and glycerol. these are then taken up in the lacteals by active transport.

thanks a lot

 

[Anees2rehman]

What r the advantages and disadvantages of using antibiotics??? Plz answer

 

[♥Яαηõõşḧ♥]

why do the fats get absorbed by the lacteals of the villi of the ileum but not the duodenum ?

 

[Anees2rehman]

Duodonem has lacteals????

 

[♥Яαηõõşḧ♥]

idk does it?

 

[Anees2rehman]

Lol no. Fats r digested in the ileum

 

[♥Яαηõõşḧ♥]

ok so the duodenum is just for emulsification but complete digestion os in the ileum .. right ?

 

[asma tareen]

well advantages are that they kill bacteria and protects the body against the diseases caused by the bacteria
disadvantages is that they can not act against viruses and they can make bacterias resistant due to which higher intake of anti biotc is required
do correct me if m wrong
