An experienced nurse who has just done a cervical exam on your patient calls you to Labor and Delivery. She reports that she believes the vertex is not presenting. You perform a vaginal examination and confirm the presenting part is not the vertex. In considering malpresentations, which of the following portions of the fetus that is foremost, or presenting, in the birth canal is not compatible with a vaginal delivery? a. Compound
b. Shoulder
c. Brow
d. Face mentum anterior

The correct answer is - B. shoulder

Explanation:

The position of a fetus is facing towards the back of the mother in normal condition with the face and body angled to one side and the neck flexed, and the standard presentation is headfirst.

An abnormal position is facing forward instead of rearward, and abnormal presentations include four parts that are face, brow, breech, and shoulder.

In this particular case, all three presentations are compatible with vaginal delivery in the birth canal except the shoulder as it is not compatible according to the malpresentation described in the question.

Thus, the correct answer is - B. shoulder

sheep is a herbivore animal whereas grasshopper belongs to the class chordates but both of them feed on greens.  

if grasshopper and sheep feeding on a pasture land, i do not think both of them will have any impact on each other. however, the number of the species can make difference. since sheep feed on greens, there is a possibility there left no pasture land for the grasshoppers or they may get extinct.

1: most common garden plants prefer loam — soils with a balance of different-sized mineral particles (approximately 40% sand, 40% silt, and 20% clay) with ample organic matter and pore space. however, some plants grow better in sandy soils, while others are well-adapted to clay soils.

2: available water capacity is the maximum amount of plant available water a soil can provide. it is an indicator of a soil's ability to retain water and make it sufficiently available for plant use. available water capacity is the water held in soil between its field capacity and permanent wilting point.

3: it is the same for all living things (plants and animals). it also includes very tiny organisms that our eyes cannot see. they are known as microorganisms, and include viruses, bacteria and fungi.
