Answer:
Bivalirudin is a DTI that overcomes many limitations seen with indirect thrombin inhibitors. It is a short, synthetic peptide that is potent, highly specific, and a reversible inhibitor of thrombin. Bivalirudin inhibits both circulating and clot-bound thrombin, while also inhibiting thrombin-mediated platelet activation and aggregation. It has a quick onset of action and a short half-life, without binding to plasma proteins (other than thrombin) or red blood cells.
Explanation:
Bacteria: They are in your intestines to break down food and produce vitamin k your body needs.
Protist: Plant-like protists produce almost one-half of the oxygen on the planet through photosynthesis.

Answer:
The correct answer is - the cell membrane.
Explanation:
When a human cell gets an external stimulus it triggers the production of the specific compound or chemical release which is packed in vesicles from the endoplasmic reticulum and Golgi apparatus to the cell membrane. The cell membrane is the cell organelle that allows or prohibits the entry or exit of any substance.
Chemical release or secretion also depends on the cell membrane and it allows the secretion of chemicals and plays an important role in the secretion of chemical, hormones, or any substance.
Answer:
Objective Lens Magnification = ×100
Explanation:
In a microscope, the ocular (eyepiece) lenses are usually to a magnification of ×10, meaning that it magnifies the image 10 times. While the standard objective lenses have magnifications of ×4, ×10, ×40, and ×100.
In order to work out the total magnification, the individual magnifications of the ocular and objective lenses have to be known, after which a simple multiplication of both magnifications will give the total magnification used.
Total Magnification = (eyepiece lens magnification) × (objective lens magnification)
1000 = 10 × obejcetive lens magnification
Dividing both sides by 10
Objective lens magnification = 1000 ÷ 10 = 10
∴ Objective lens magnification = ×100
