Answer:
The molarity of a solution prepared by dissolving 54.3 g of Calcium nitrate into 355 mL of water is 0.9881M
Molarity of solution is the ratio of the number of moles of the substance to the volume.
n is the number of moles of the compound
Mass of calcium nitrate = 54.3g
Molar mass of calcium nitrate = Ca(NO₃)₂ = 164.088 g/mol
Get the required molarity;
Hence the molarity of a solution prepared by dissolving 54.3 g of Calcium nitrate into 355 mL of water is 0.9881M

In two common species of flowers, a and b, the proportions of flowers that are blue are pa and pb , respectively. Suppose that independent random samples of 50 species-a flowers and 100 species-b flowers are selected. Let pˆa be the sample proportion of blue species-a flowers and pˆb be the sample proportion of blue species-b flowers. What is the mean of the sampling distribution of pˆa−pˆb ?.
The mean of the sampling distribution is [tex]{p_{a}}-p__b}[/tex]
The mean of a sampling distribution is the population mean from which values are sampled. For a population of mean μ, the mean of the sampling distribution is [tex]\mathbf{ \mu_x}[/tex]
∴
[tex]\mathbf{\mu_x = \mu}[/tex]
From the parameters given:
Suppose that independent random samples of 50 species-a flowersand 100 species-b flowers are selectedwhere;
[tex]\mathbf{\hat p_a}[/tex] = sample proportion of blue specie-a[tex]\mathbf{\hat p_b}[/tex] = sample proprotion of blue specie-bThe mean of the sampling distribution of [tex]\mathbf{\hat p_a -\hat p_b}[/tex] is [tex]{p_{a}}-p__b}[/tex]

The concentration of sodium on the inside of the cell is 20 mm. The outside of the cell has a sodium concentration of 115 mm. Which mechanism of ion uptake would best move sodium from the inside of the cell to the outside?.
The mechanism of ion uptake that would best move sodium from the inside of the cell to the outside is ACTIVE TRANSPORT. It is a mechanism that requires energy.
Active transport is a mechanism used by cells to move substances and ions against a concentration gradient.
In active transport, substances are moved across biological membranes from a region of low concentration to a region of high concentration.

Lydia graphed δlmn at the coordinates l (0, 0), m (2, 2), and n (2, −1). She thinks δlmn is a right triangle. Is lydia's assertion correct?.
No product results in -1, hence δlmn is NOT a right triangle showing that lydia's assertion is incorrect
Perpendicular linesIn order to determine whether triangle lmn is right-angled, we need to determine the slope of lm, ln, and mn first as shown:
For the slope of lm:
[tex]m_{lm} = \frac{2-0}{2-0}\\ m_{lm} =2/2\\m_{lm} =1[/tex]
For the slope of ln:
[tex]m_{ln} = \frac{-1-0}{2-0}\\m_{ln} =-1/2\\[/tex]
For the slope of mn:
[tex]m_{mn} = \frac{-1-2}{2-2}\\m_{ln} =-3/0 = \infty\\[/tex]
If any of the two lines is perpendicular, hence the triangle lmn is right-angled.To check, we will take the product of the slopes and see if it is equivalent to -1.Product of slope lm and ln
[tex]m_{lm}\times m_{ln} = 1 \times -1/2\\m_{lm}\times m_{ln} = -1/2[/tex]
Since no product results in -1, hence δlmn is NOT a right triangle showing that Lydia's assertion is incorrect

There are different scales in music. The C major (or the key of C) is known to be a major scale that is often based on C. It is made up of different pitches C, D, E, F, G, A, and B.
C major is simply known to be one of the most user key signatures found in music. It is known to have its key signature to have no flats and no sharps keys.
The C major scale is known to have the scale of zero sharps or flats. It does not have any key signature and it makes it easier to identify any music in the key of C major.
For one to be able to play the C major scale ascending, one must start with the root note C and play the notes in order: C - D - E - F - G - A - B - C. Then, one can either go right back down the scale of B - A - G- F- E - D.
