Explanation:
These questions are related to the extraction of DNA using detergents and ethanol.
1. Consistency and texture- the extracted DNA is white, spongy and moist or slime in nature.
2. Salt is used during the extraction process as the DNA is negatively charged molecule and to neutralize the negative charge which will allow the formation of precipitate.
3. The DNA is soluble in aqueous solution as the DNA is a negatively charged molecule therefore the negative charge makes it a polar molecule and it can form the interactions in the aqueous solution.
4. RNA could be present in the aqueous solution along with the DNA as both are the nucleic acid.
5. The base-pairing rule was suggested by the Chargaff who proposed that Adenine binds thymine and guanine binds cytosine.
5. The binding of adenine to thymine involves two hydrogen bonds and between guanine to cytosine involves three hydrogen bonds.
Answer:
Explanation:
in all the question we have to use same technique
in 1 question
weight/force exerted by dorje(F)=1500N
total surface area of sole(A)=0.5m²
we know that,
P=
or, p=
∴ P=3000pa
in question 2nd
pressure(P)=40 pa
force exerted by block(F)=80N
we know,
pressure(P)=
area=
∴area =2m
ow you can do other by yourself
The blood electrolytes—sodium, potassium, chloride, and bicarbonate—help regulate nerve and muscle function and maintain acid-base balance and water balance. ... Thus, the kidneys help maintain a balance between daily consumption and excretion of electrolytes and water.
One of the negative impacts of eutrophication and increased algal growth is a Loss of oxygen known as anoxia
Explanation:
In this case, I would suggest looking at the overall color of the bird as well as notable color patches on the wings, tail, or the head.
Also note whether or not the edges where colors meet are blurred or smooth/blended.
