Plate tectonics located in our crust crashing or colliding into each other cause earthquakes to occur.
Viruses reproduce by incorporating
their DNA into an organism's genome to tap into the
host replication mechanism to reproduce themselves.
Viruses, therefore, cannot copy outside their host. This property of viruses makes them suitable
for the production of transgenic
organisms. This is achieved by replacing
the DNA piece that causes virulence in the virus with the desired gene
that is to be transduced into the host organisms.
Answer:
population = 600
heterozygotes = 2pq
The homozygous recessive percentage = 
q = 0.1
Solve for q:
∴ q = 
∴ q = 
∴ q = 0.316
solve for p:
for p + q = 1,
thus p = 1 – q = 1 – 0.316 = 0.684
The heterozygotes = 2pq
2pq = 2 x 0.316 x 0.684 = 0.432
600 x 0.432 = 259.2 = 259
so, the population reaches Hardy Weinberg equilibrium, 259 of indviduals should be heterozygous for this trait.
Hence, the correct answer is 259

Answer:
C
Explanation:
A rainforest is humid, therefore, water uptake would likely not be an issue. However, rainforests have a huge number of trees, often these are very tall. These large trees might block out the sun from the smaller plants nearer the ground. This means they would struggle to properly photosynthesise, as they wouldn't have the necessary light energy.
Therefore, as a survival adaptation, it is likely that an allele that produced broader leaves for photosynthesis would be selected for in this population. Broader leaves would give a larger surface area for the plant to absorb light energy to perform photosynthesis.
Answer: D
Explanation:
x+10x = Tx*+ Water: water molecules move | Potato x+10Water = Potato slice in pure water
so the Answer is D
