Answer The stomach secretes acid and enzymes that digest food. Ridges of muscle tissue called rugae line the stomach. The stomach muscles contract periodically, churning food to enhance digestion.

Which of the three primary germ layers generates most of the cells in the developing mammalian forelimb? which germ layer genera

almond37 [142]

Germ layer is a primary layer of cells found in the embryo. The three primary germ layers that generate most of the cells in the developing mammalian forelimb are ectoderm, mesoderm and endoderm.
Ectoderm forms the outer component of a mammalian body such as skin, hair, etc. Endoderm forms the inner layer that comprises of the linings of digestive system, lungs and thyroid. Mesoderm is the middle layer that forms the skeletal system, heart, etc.
Neural tube is generated by the inward folding of the ectoderm. This process is called neurulation. Ectoderm also forms neural crest.

A pathogenic bacterium has been engulfed by a phagocytic cell as part of the nonspecific (innate) immune response. What would be

bezimeni [28]

Complete question:

A pathogenic bacterium has been engulfed by a phagocytic cell as part of the innate immune response. Which of the following illustrations best represents the response?<em> Illustrations in the attached files.</em>

Answer:

Graph C best represents the response

Explanation:

Phagocytosis occurs when the phagocyte incorporates a new solid substance, such as a bacteria. Phagocytosis is a function of specialized immunological system cells. They are capable of removing strange bodies from the immune system as a first natural defense line. The phagocyte membrane invaginates and surrounds the strange body, which is traped and included in an endocytic vesicle called a phagosome. This vesicle often fusses a lysosome which releases its enzymes into the phagosome. These enzymes are in charge of digesting or destroying the strange content. After that, the produced wastes are removed from the cell.
