Answer:
The answer is the first option. The trailing edge is composed of many filopodia containing tight parallel bundles. These filopodia push trailing edge away from the location it was previously occupying.
Explanation:
Cells migrating in tissues exhibit both filopodia and lamellipodia. These thin protrusive extensions are ideal for exploring and penetrating tissue spaces. They are also well suited for intercalating between cells, such as during the migration of leukocytes across endothelial layers.
Therefore the answer is the first option.
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
