Answer: the name used is polytene chromosomes.
Explanation:
Polytene chromosomes are produced when repeated rounds of deoxyribonucleic acid (DNA) replication without cell division forms a giant chromosome, they have thousand of DNA strands and provides high level of function in the salivary glands.
At interphase, polytene chromosomes are seen to have distinct thick and thin banding patterns, these bands are of 2 types, the dark band (dark stained,
contains more DNA and less RNA) and the interband (light stained, more RNA and less DNA). The bands enlarge and forms a swelling called puff in certain times, the puffing (which is the formation of puff) is caused by the uncoiling of individual chromomeres in a band. The puffs indicate the site of active genes where mRNA synthesis takes place. These distinct banding patterns are used to study the function of genes in transcription because they permit high level of gene expression.
Answer:
in summer we wear light coloures and mostly cotton clothes because we swear a lot and cotton is good absorber of water and light cloth so that it does not absorb more heat .
In winter we wear dark coloured and woolen othes to keep us warm the dark coloured clothes helps to absorb heat and keep us warm
Oxygen,carbon,nitrogen and hydrogen hope this helps
Answer:
The correct answer is option d. "differential media".
Explanation:
Differential media is defined as a bacteriological growth strategy that allows to distinguish selected species by using specific ingredients in the media. In the example, after inoculation one plate allowed the growth of two organisms but one with a changed color. This plate description fits with a differential media, allowing to distinguish among different microorganism based on its color. Therefore, it is correct to assume that this plate belongs to the differential media.
