Stage 1

Stage 4

3. Low molecular weight heparin (LMWH) is a class of anticoagulant medications. Which is a characteristic of low molecular weight heparin?

It consists of large fragments of heparin.

It binds to plasma proteins as strongly as standard heparin.

It can be administered subcutaneously.

It has more side effects than standard heparin.

Answer 1

Ans 1) Astrocytic tumors

Explaination:

Glioblastoma multiforme (GBM) is the most common and deadliest of malignant primary brain tumors in adults and is one of a group of tumors referred to as gliomas. Classified as a Grade IV (most serious) astrocytoma, GBM develops from the lineage of star-shaped glial cells, called astrocytes, that support nerve cells.

2) Stage 4

Explaination:

Stage 4 in the viral life cycle of hepatitis involves the production of antibodies where new bacteriophage forms.

3) It can be administered subcutaneously

Explaination:

Although LMWH and UFH work similarly to inhibit clotting factors, LMWH can be self-administered at home via subcutaneous (under the skin) injection and does not require regular blood monitoring necessary for UFH treatment. As with all heparins, LMWH dosing is based on a patient's weight.
