I FORGOT HOW TO SHOW THE SLIDE BUT -Yosef is so intrigued by what he sees in his microscope that he walks to a nearby pond and c

ollects a sample of pond water to learn more about paramecium. He uses a single drop of the pond water to create a wet mount slide, which allows him to see living paramecia moving around in the water, unlike the processed and dyed paramecia in the prepared slide How do the structures observed under magnification help the organism carry out basic functions of life? - PLS HELP IT WAS DUE YESTERDAY

The structure of paramecium observed under magnification that helps the organism carry out basic functions of life is ; CILIA

The paramecium has a oral surface and a dorsal body surface that is covered with pellicles ( elastic firm membrane ) that supports the cell membrane of the paramecium.  while The whole body of a paramecium is covered with Cilia ( hair like filaments ) that supports the propelling movement of the paramecium and the movement of food particles into the mouth of the paramecium.

The basic function of a paramecium are ; (i) movement and ( ii ) feeding. the CILIA is the structure that helps the organism to carry out these functions.

Hence we can conclude that structure of paramecium observed under magnification that helps the organism carry out basic functions of life is CILIA .

What is the concentration of a potassium iodate solution after you complete the following porcedure? Pipette 10 mL of a 0.31 M p
zubka84 [21]

<u>Given:</u>

Initial concentration of potassium iodate (KIO3) M1 = 0.31 M

Initial volume of KIO3 (stock solution) V1 = 10 ml

Final volume of KIO3 V2 = 100 ml

<u>To determine:</u>

The final concentration of KIO3 i.e. M2

<u>Explanation:</u>

Use the relation-

M1V1 = M2V2

M2 = M1V1/V2 = 0.31 M * 10 ml/100 ml = 0.031 M

Ans: The concentration of KIO3 after dilution is 0.031 M

Red light has a wavelength of about 6.5 x 10-7m. Find its frequency. Show all work.
ozzi
For this problem we use the wave equation. It is expressed as the speed (c) is equal to the product of frequency (f) and wavelength (v).

c = v x f

We know the wavelength of the an red light which is 6.5 x 10^-7 m. Now, we solve for the wavelength of the unknown wave to see the relation between the two waves.

2.998 X 10^8 = 5.3 X 10^15 X v
v = 2.998 X 10^8 / (5.3 X 10^15) = 5.657 X 10^-8 m

Therefore, the wavelength of the unknown wave is less than the wavelength of the red light.

HNO3 is an Arrhenius ______________ and increases the concentration of __________ when added to water.
poizon [28]
HNO3 and H2SO4 are Arrhenius acids which will increase the concentration of H+ when dissolved in water.

KOH and Ca(OH)2 are Arrhenius bases that increase the concentration of OH- when dissociated in water.

What mass of agno3 can be dissolved in 250g of water at 20°c?
Mice21 [21]
Hello there,

You should know the <span>solubility of AgNO3 in water at 20°C equals to 2220 g/L.

So we can say that in 1 L of water, 2220 g of AgNO3 can be dissolve.

Now you should know 1L = 1000g.

Which means 1000 g of water can dissolve 2220 g of AgNO3.

Therefore :

</span>250 g<span> --> x
1000 g --> 2220 g

So : </span>x = \frac{250*2220}{1000} =  \frac{555000}{1000}= 555g.

In short, 555g of AgNO3 can be dissolved in 250g of water at 20°C.

Hope this helps !
