Answer:
1816
Explanation:
The earliest weather charts were made by collecting synchronous weather reports by mail. However, it was not until 1816 that German physicist Heinrich Wilhelm Brandes created the first weather maps, which were hand drawn and reconstructed from data collected in 1783.
Answer:
<h2>11.02</h2>
Explanation:
Predict the frequency of a+b+c progeny = 11.02
Step by step Explanation for all genes
a---8%----b---------24%--------c
Double cross overs = (RF at first locus × RF at second locus)/100
= 8 × 24 /100 =1.92
Double cross over progeny;
a b+ c =0.96
a+ b c+= 0.96
single cross over progeny;
RF = 8
SCO at first locus progeny= 8 -DCO progeny= 8- 1.92 = 6.08
a b+ c+= 3.04
a+ b c= 3.04
single cross over at second locus progeny---
RF = 24
SCO at second locus progeny= 24-DCO progeny= 24 - 1.92 = 22.02
abc+= 11.02;
a+b+c = 11.02;
Total recombinants = 1.92 + 6.08 + 22.02 = 30.02
Total nonrecombinants are = 100 - 30.02 = 69.98
abc = 34.99
a+b+c+ = 34.99.
Answer :
Vinegar is a weak acid. This is used to make a naked egg. When an egg is added in the vinegar for one day / 24 hrs, it reacts with the eggshell. The calcium carbonate shell gets dissolve.
Then an egg without shell is formed and the size of the egg does not change. The calcium carbonate reacts with acetic acid and forms carbon dioxide.
When the shell-less egg is kept in the vinegar for 48 hrs i.e. 2 days again, the water content in it enters into the eggs through the membrane. Then the egg gets somewhat bigger.
Otherwise, for 24 hrs, vinegar is acting like an isotonic solution and only dissolves the shell. This experiment would be done for showing the osmosis process through the cell membrane.
