Answer:
B. The cells have no nucleus
Explanation:
The prokaryotic cells has no nucleus
Answer:
The correct answer is option d. "x-rays".
Explanation:
The devastating gravitational force that a black hole has against matter produces that matter rises its temperature to million degrees. As a consequence of the extreme heat that it experiences, matter glows x-rays before being engulfed by a black hole. Since no light can escape black holes, scientists can spot their presence by studying its surrounding environments including the presence of immense gravitational forces and x-rays emissions.
Answer:
0.32
Explanation:
Hardy Weinberg equilibrium states that the frequency of allele will remain the same in the absence of disturbances such mutation,no gene flow, no selection, random mating and infinite population size
the equilibrium is defined the equation
p² + 2pq + q²
where q² = f, frequency of the homozygous recessive allele, p² = f, of the homozygous dominant allele and 2pq is the frequency of the carrier of the dominant + rh blood factor
q² = 0.04
q = √0.04 = 0.2
and p + q = 1
p = 1 - 0.2 = 0.8
therefore 2pq = 2 × 0.8 ×0.2 = 0.32
They all contribute to genetic diversity, alternative D.
