33.11 km is not very far, if it was that close we would all be dead
<span>Molecular scientists can read the DNA code and compare the DNA of different organisms. This concept is ude in molecular clocks to determine the Moleular Phylogenies. It is letter B. Hereditary molecular differences are being analyzed in phylogeny which is mainly from the DNA sequence in order to acquire information on the evolutionary relationships of an organism.</span>
Answer:
Y= 98, 0% , Z = 94,7 %
Explanation:
We use simple 3 rules to find the percentage of purity, using mass data:
Sample Y =
85g----100%
83,30g----X = (83,30gx 100%)/ 85g= 98, 0%
Sample Z =
95g----100%
90g----X = (90gx 100%)/ 95g= 94, 7%
Answer:
See the answer below
Explanation:
<em>Recall that the law of dilution states that the number of moles before dilution must be equal to the number of moles after dilution.</em>
Mathematically,
molarity x number of moles before dilution = molarity x number of moles after dilution.
For solution A: final molarity = 3 mM, final volume = 2mL, initial molarity of KMnO4 = 10 mM
Applying the equation:
10 x initial volume = 3 x 2
initial volume = 6/10 = 0.6
<u>Hence, Tube A should be made with 0.6 mL of 10 mM KMnO4 stock and 1.4 mL of distilled water to give a solution of 2 mL 3 mM KMnO4.</u>
For solution B:final molarity = 8 mM, final volume = 2 mL, initial molarity = 10 mM
10 x initial volume = 8 x 2
initial volume = 16/10 = 1.6
<u>Hence, Tube B should be made with 1.6 mL of 10 mM KMnO4 stock and 0.4 mL of distilled water to give a solution of 2 mL 8mM KMnO4. </u>
The rough endoplasmic reticulum (RER) is is a series of flattened sacs connected to ribosomes. The Golgi Apparatus is an organelle composed of flattened stacked pouches known as <em>cisternae</em>.
In this case, the missing words indicate:
- Specifically, this organelle is attached on the ROUGH ENDOPLASMIC RETICULUM (RER) which will help to modify and package the polypeptide product.
- It puts it into a transport vesicle to be sent over to the GOLGI APPARATUS to add molecular tags and sort it, like a post office.
- The RER is required for the production and secretion of different hormones and proteins.
- The Golgi apparatus plays fundamental roles associated with the transport, modification, and packaging of proteins and lipids into vesicles, which are subsequently delivered to specific cellular destinations.
- Both the RER and Golgi apparatus form part of the endomembrane system.
