Your answer is Adenosine diphosphate (ADP)
A cell membrane can me compared to a wall, one that is flexible and malleable but strong enough to repel unwanted things from the cell. it also keeps the cell together in its shape and form
SEM and TEM are electron microscopes whereas the SEM uses reflected electrons and TEM uses transmitted electrons to form an image
Explanation:
- SEM is the scanning electron microscopes and TEM is the Transmission electron microscope
- SEM works by detecting the scattered electrons to create an image of the sample whereas the TEM detects the transmitted electrons to create the image of the sample
- SEM will only be analysing the surface of the sample whereas TEM collects data vertically also
- TEM sample needs to cut thinner than SEM and TEM will give high-resolution images than SEM
Answer:
Seen on the explanation.
Explanation:
Glandular tissues are a mixture of both endocrine (ductless, hormones are secreted directly into the blood) and exocrine (have ducts, hormones are secreted into surfaces) glands.
The pancreas and salivary glands are both exocrine glands although the pancreas has an endocrine function via the islets of Langerhans, both aid in the digestion of food.
The pancreas lacks striated ducts and the intralobular duct is similar to the intercalated duct of salivary glands. It often has a collapsed lumens and the cells are cuboidal with little cytoplasmic staining in contrast to acinar cells.
The pancreas can also be distinguished from the parotid gland by the presence of the pancreatic islet (islets of langerharns) which has an endocrine function.
