Explanation:
r:grasshoppers and cockroaches different in colour, habitat, and body mechanism .
Explanation: grasshoppers coluor range is green while cockroaches colour is redishBrown
Grasshoppers habitat is grass while cockroaches habitat is watery (wet) and dirty places.
Theses are observable differences.
Answer:These organs expel water from the body, helping to maintain osmotic balance.
Explanation:
Well there is in fact other life in outer space but in the form of bacteria
Answer:

Explanation:
Given frequency of the two alleles i.e "B" and "b" are equal .
As per Hardy–Weinberg equilibrium, sum of frequency of the two alleles is equal to one.
i.e 
Since 
and
will be equal to 0.5
Frequency of genotype "BB"

Frequency of genotype "bb"

As per second equation of Hardy–Weinberg equilibrium,

Substituting the values of p and q in above equation we get -

Red beetles have genotype BB and Bb
number of red beetles with genotype (BB)

number of red beetles with genotype (BB)

Total red beetles

Frequency of red beetles
