A particular viral genome can replicate in 8 hours. If you start with 55,000 copies of this genome, about how many copies would

deff fn [24]

If a viral genome can replicate in 8 hours and the starting copies is 55,000, the number of copies after 48 hours would be 3,360,000 copies

<h3>Replication rates</h3>

The starting number is 55,000 and replication happens every 8 hours.

Starting from 0 hours, the genome would 55,000

After 8 hours = 55,000 x 2 = 110,000 copies

After 16 hours = 110,000 2 = 220,000 copies

After 24 hours = 220,000 x 2 = 420,000 copies

After 32 hours = 420,000 x 2 = 840,000 copies

After 40 hours = 840,000 2 = 1,680,000 copies

After 48 hours = 1,680,000 x 2 = 3,360,000 copies

Which are causes of desertification?

makvit [3.9K]

Answer: Overgrazing is the major cause of desertification worldwide. Other factors that cause desertification include urbanization, climate change, over drafting of groundwater, deforestation, natural disasters and tillage practices in agriculture that place soils more vulnerable to wind.

-<br> Calculate the molar mass of a gas that has a density of 1.55g/L.

VLD [36.1K]

Answer: 39.86 g/mol

Explanation:

Assuming this gas is at a pressure of $0.99 atm$ and a temperature of $37 \°C+273.15=310.15 K$ , we can solve this problem with the Ideal Gas Law equation:

$P.V=n.R.T$ (1)

Where:

$P=0.99 atm$ is the pressure of the gas

$V$ is the volume of the gas

$n$ the number of moles of gas

$R=0.0821 \frac{atm.L}{mol.K}$ is the gas constant

$T=310.15 K$ is the absolute temperature of the gas in Kelvin

On the other hand, we know the density $\rho=1.55 g/L$ is given by a relation between the mass $m$ and the volume $V$ :

$\rho=\frac{m}{V}$ (2)

Then, the mass is:

$m=\rho V$ (3)

Another important fact here is that the molar mass $M_{mass}$ of an element is given by a relation between the mass of that element and the number of moles $n$ it contains:
