Hi , Iam back again . Sorry for the previous post, i made some typo mistakes . Man , i felt exhausted , is anybody in the same boat with me ? I will take my test in the end of July, but there are many things I need to know for DAT . Okie , here we are...

a. Musculoskeletal system
b. Portions of the digestive and respiratory organs
c. Circulatory system
d. Connective tissue
e. All of the above are arise from the mesodermal layer

Which of the following arises from the endodermal layer?
a. Lungs
b. Epithelial lining og the digestive tract
c. Retina of the eye
d. a and b
e. b and c

Which of the following is true regarding lipids?
a. They are composed primary of the elements C, H,O &N
b. Maltose is an example of a lipid
c. The C: H ratio is 1:2:1
d. The secondary structure is composed of alpha helices and beta pleateds sheets.

The mesoderm gives rise to all of the following except :
a. Musculoskeletal system
b. Portions of the digestive and respiratory organs...digestive is epithelial cells from ectoderm
c. Circulatory system
d. Connective tissue
e. All of the above are arise from the mesodermal layer

Which of the following arises from the endodermal layer?
a. Lungs
b. Epithelial lining og the digestive tract
c. Retina of the eye
d. a and b....same reason above
e. b and c

Which of the following is true regarding lipids?
a. They are composed primary of the elements C, H,O &N ---> not made of Nitrogen, only C:H:O
b. Maltose is an example of a lipid -----> Maltose is a carbohydrate digested from sucrose into 2 glucose molecules
c. The C: H ratio is 1:2:1
d. The secondary structure is composed of alpha helices and beta pleateds sheets. -----> this is talking about secondary structure of proteins
e. It is the chief means of long term food storage in animals

nice test keep em coming, ill post one up later today or tomorrow

good questions..😀
 
this is my answer.

Mesodermal Tissue

* Connective Tissue
* Muscle
* Dermis
* Urogenital system
* Serous membranes
* Vascular system, including lymphatics
* Adrenal Cortex
* Spleen
* Dental Pulp






Which of the following arises from the endodermal layer?
a. Lungs
b. Epithelial lining og the digestive tract
c. Retina of the eye
d. a and b
e. b and c

Endodermal Tissue
* Gastrointestinal system
* Thyroid
* Parathyroid
* Thymus
* Liver
* Pancreas
* Lining of respiratory system, bladder, and urethra


Note: This one is tricky because, to my knowledge only the lining of the lungs comes from endoderm. In a situation (eg class) I would argue this one with a prof, but in this instance I would say that the lung is a derivative. Just don't over think these things too much.

Which of the following is true regarding lipids?
a. They are composed primary of the elements C, H,O &N
No because the structure is CHO and CHOP (for phospholipids)

b. Maltose is an example of a lipid
Nope, a sugar (a disaccaride of glucose)
c. The C: H ratio is 1:2:1
Damn, I cannot remember what the ratio is!
d. The secondary structure is composed of alpha helices and beta pleateds sheets.
Nope, Proteins
e. It is the chief means of long term food storage in animals
 
yeah guys im sure about my answers if the o/p doesnt respond

The mesoderm gives rise to all of the following except :
a. Musculoskeletal system
b. Portions of the digestive and respiratory organs (lining of both is endo)
c. Circulatory system
d. Connective tissue
e. All of the above are arise from the mesodermal layer

Which of the following arises from the endodermal layer?
a. Lungs
b. Epithelial lining og the digestive tract (lining of ****)
c. Retina of the eye
d. a and b
e. b and c

Which of the following is true regarding lipids?
a. They are composed primary of the elements C, H,O &N
b. Maltose is an example of a lipid
c. The C: H ratio is 1:2:1
d. The secondary structure is composed of alpha helices and beta pleateds sheets.
e. It is the chief means of long term food storage in animals (fat =lipid)

E. All Of The Above Are Arise From The Mesodermal Layer

If U Guys Look Up In The Kaplan Book, (embryology Chapter, Gastrulation ) , The Mesoderm : Musculokeletal System , Cirlulatory System, Excretory System, Gonads , Connective Tissue Throughout The Body, And Portions Of Digestive And Respiratory Organs
Which Of The Following Arises From The Endodermal Layer?
A. Lungs
B. Epithelial Lining Og The Digestive Tract
C. Retina Of The Eye
d. A And B
E. B And C

Which Of The Following Is True Regarding Lipids?
A. They Are Composed Primary Of The Elements C, H,o &n
B. Maltose Is An Example Of A Lipid
C. The C: H Ratio Is 1:2:1
D. The Secondary Structure Is Composed Of Alpha Helices And Beta Pleateds Sheets.
e. It Is The Chief Means Of Long Term Food Storage In Animals
 
The first question is tricky but I think it should be E. You answer B, because you argue that the linings of the digestive and respiratory organs are endoderm. However, think about what you are saying by putting B:

"The mesoderm will give rise to all of the following, except for portions of the digestive and respiratory organs."

However, mesoderm DOES give rise to portions of these organs (all but the linings, which we agree are endoderm). Therefore, the answer is E.
