Describe one similarity and one diffence between DNA and RNA
AveGali [126]

Nucleic acids are the biolmolecules which are responsible for carrying information from one generation of organisms to the other. There are two types of nucleic acid namely the deoxyribo nucleic acid (DNA) and the ribo nucleic acid (RNA).

The similarity between the DNA and RNA is that both act as the genetic material carrying genetic information in them. Both are made up of polynucleotide chain with the repeating units called the nucleotides containing a nitrogenous base, a pentose sugar and phosphate. The difference lies in the type of the sugar and nitrogenous bases present. In RNA, the sugar is a ribose. In DNA, the sugar is a deoxy ribose derived from a ribose sugar by the loss of an oxygen atom. The nitrogenous bases of DNA are the adenine, guanine, thymine and cytosine. Whereas, the nitrogenous bases of RNA are the adenine, guanine, cytosine and uracil. Also, DNA is a double stranded molecule with two polynucleotide chains, whereas RNA is single stranded.

What will happen to the sand when you pour water into the river??
Ainat [17]

When we mix sand and water, no reaction takes place. The sand simply settles down at the bottom of the water container. This is because sand is heavier than water and hence cannot float in water. ... In comparison, if we mix something like salt or sugar in water, they will react and make the water salty or sweet.

Wavy hair in mice is a recessive genetic trait. if mice with wavy hair are mated with straight-haired (heterozygous) mice, each
kondaur [170]

In order to find the percentage of the litters that will consist of two wavy- haired and three straight-haired offspring, you need to use the binomial distribution formula: P(x) = ⁿCₓ × pₓ × qⁿ⁻ˣ

P is the probability that the litters will consist of two wavy-haired and three straight-haired offspring.

X is considered to be the number of times the offspring will have wavy-air in a litter of 5 offspring, which is 2.

n is the number of offspring per litter.

p is the probability of happening wavy hair.

q is the probability of having straight hair.

It comes like this:

P(X=2)=⁵C₂×0.5²×0.5⁵⁻² ⇔ P(X=2)=10×0.25×0.125 ⇔ P(X=2)=0.3125

So, the percentage of the litters that will consist of two wavy-haired and three straight-haired offspring is 31.25%.
