Answer:

The streaks made by the limonite are yellow, and the streaks made by Mary and Jim’s sample are brown. Therefore, they are not the same mineral. The rock is not made of limonite.

identify the missing numbers below to show the result of multiplying the numbers. (3.5 × 1016)(2.2 × 1010) = a × 10b
11Alexandr11 [23.1K]
<span>In order to find the value of "a" and "b", first of all perform the multiplication in the parenthesis. 
Thus

(3.5x1016) = 3556
and 
(2.2x1010) = 2222

As per question;
(3556)x(2222) = 10 axb
By dividing both sides by "10"
we get
(3556)x(222.2) = axb
or 
(355.6)x(2222) = axb
by comparing both sides of the equation, 
we get that a = 3556  and b = 222.2
or
a = 355.6 and b = 2222

Describe the steps in making packaging and exporting a protein from a cell
irina [24]

<u>Answer:</u>

<em>The steps in making packaging and exporting a protein from a cell are listed below in the following points:</em>

  • <em>Protein is made from the Ribosomes.</em>
  • <em>These proteins are gathered in the endoplasmic reticulum. </em>
  • <em>From ER the proteins are exported to the Golgi bodies. These Golgi apparatus is found in the vesicles.</em>
  • <em>The Golgi bodies modify the protein to suitable forms that can be absorbed.</em>
  • <em>Finally it is transported to all part of cells in our body.</em>

Egg membranes from three eggs were carefully taken out and labeled as a, b , c. Each of these membranes were filled with 1% solu
Readme [11.4K]

Answer:

The correct answer would be -

Membrane A - Hypotonic solution - the movement of water towards inside the cell

Membrane B - Isotonic soltion - there will be no movement of water

Membrane C - Hyertonic solution - the movement of water towards outside of the cell

Explanation:

This experiment deals with tonicity as this solution will affect the tonicity of the egg membrane. In membrane A there are more solutes inside the cell than outside the cell so it is hypotonic solution so the movement of water will be towards inside the cell.

In membrane B the solutes are equal in both sides so there will be no movement as its isotonic condition while in membrane C the solution is in hypertonic situation as the solutes are more outside than inside.

Thus, the behavior of the membranes are-

Membrane A - Hypotonic solution - the movement of water towards inside the cell

Membrane B - Isotonic soltion - there will be no movement of water

Membrane C - Hyertonic solution - the movement of water towards outside of the cell

B. Eggs are known to contain cholesterol, which is a lipid. Did your experiment results indicate a presence of lipids in the alb
Darya [45]

Answer:

According to the result recorded, there was no cholesterol in the albumin solution. This is probably because the cholesterol is in the egg yolk and not the egg white. In order to get a positive response on the presence of cholesterol in eggs, an egg yolk albumin stock needs to be prepared. So using the same procedure as before and only replacing the egg yolk for the egg white, prepare a 0.5 mL of egg yolk with 4.5 mL distilled water mixture in a test tube. Follow the steps given in the lab manual to check for presence of lipids in this albumin stock. Take a filter paper and add one drop of Sudan III solution onto it, let it dry and then place a drop of the stock prepared and analyze if the color transfer happens.

Hope that answers the question, have a great day!
