If 0.5 ml of a mumps virus vaccine contains 5000 units of antigen, how many units would be present in each milliliter if the 0.5

5000 units of antigens are present in 0.5 mL of the mumps virus vaccine.

Volume of the vaccine after dilution with water = 2 mL

0.5 mL has 5000 units antigen. So when 0.5 mL was diluted to 2 mL, the final vaccine after dilution would contain 5000 units of antigen.

Units of antigen present in 1 mL vaccine sample

= 1 mL *\frac{5000 units}{2 mL} = 2500 units

Therefore, 2500 units of the antigen will be present in each milliliter, if 0.5 mL of the vaccine is diluted to 2 mL with water for injection.

If an ideal gas at a constant temperature is initially at a pressure of 3.8 atm and is then allowed to expand to a volume of 5.6
BabaBlast [244]

Answer:

The most common example is the molar volume of a gas at STP (Standard Temperature and Pressure), which is equal to 22.4 L for 1 mole of any ideal gas at a temperature equal to 273.15 K and a pressure equal to 1.00 atm.If an ideal gas at a constant temperature is initially at a pressure of 3.8 atm and is then allowed to expand to a volume of 5.6 L and a pressure of 2.1 - 18914… ... of 5.6 L and a pressure of 2.1 atm, what is the initial volume of the gas? ... An ideal gas is at a pressure of 1.4 atm and has a volume of 3 L.

For which enzyme are nucleotides the substrate? a)l Protease b) Ligase c) Ribosome d) DNA polymerase
Lena [83]

The option (d) is correct DNA polymerase enzyme are nucleotides the substrate.

We refer to a substance as a substrate when another substance is added to it. It is defined differently in several sciences. It is a molecule or substance that, when exposed to a catalyst, enzyme, or inhibitor, causes a chemical reaction. In the field of material sciences, the term "substrate" is widely used to describe the base material on which various processing operations are carried out with predetermined reaction parameters to produce additional layers and films, such as coatings. As a result, there are numerous definitions available in the literature, depending on the substrate's applications and area of study. A molecule with which an enzyme interacts is known as a substrate. A substrate is put into the active site of the enzyme, which is where weak bonds between two molecules might form. The substrate reacts under the pressure of the enzyme, forming an enzyme substrate complex that is the product of the intended reaction. The bonds that form between the substrate and the enzyme are what induce the conformational shift, or shape change, in the enzyme.

A ------------ ----------------- is the dying out of a large number of species on a global scale
ziro4ka [17]

Answer:

Extinction event or sometimes known as Mass extinction

Explanation:

These events typically are typically widespread and rapid decrease in the biodiversity (which takes into account spread and existence of current species). The worst mass extinction was Permian–Triassic extinction where over 90% of species of organisms vanished.
