Answer:
after meiosis, each new cell will be genetically different due to random exchanges of chromosomes.
Answer:
The offsprings of this punnet square will be Dd, Dd, dd and dd in a ratio 1Dd : 1dd
See attached image for punnet square completion
Explanation:
This question involves a cross involving a single gene with alleles D and d where allele D is dominant over allele d i.e. D will mask the phenotypic expression of d in a heterozygous state.
This cross is between a heterozygous parent (Dd) and a homozygous recessive parent (dd). Parent Dd will produce gametes D and d while parent dd will produce gametes d and d.
Using these gametes in a punnet square, four possible offsprings with two distinct genotypes will be produced. The genotypes are: Dd and dd in a ratio 1:1
Hence, the possibility of having a heterozygous dominant offspring is 1/2 while the possibility of having a homozygous recessive offspring is also 1/2.

As more moisture is added to this air, the rate at which water will evaporate will probably decrease
Explanation:
As long as the air above the lake remains at a constant temperature, the relative humidity of the air will rise with increased evaporation of the water from the lake.
This will continue to increase until the relative humidity reaches approximately 50% and then the evaporation decreases until the saturation point of the air mass is reached where evaporation virtually stops because the air cannot take up more moisture. At saturation point, the rate at which the air mass loses moisture back to the lake (as dew) becomes equal to the rate at which the lake loses water to the air.

Darwin also suggested a mechanism for evolution: natural selection, in which heritable traits that help organisms survive and reproduce become more common in a population over time. A heritable trait is one that's passed on from parents to children by way of genes.
Answer:
The right answer is the prey-predator relationship.
Explanation:
The given graph details conceivably show the prey-predator relationship, in which the prey appears in red and the predator is appeared in blue. It is seen that the predator population for the most part stays less than the prey, so they can get food without any problem.
The prey-predator relationship shows that in the event that the population of prey begin to increase, at that point the number of population in the predator would increase as well, as the predators have bountiful of food. However, when the number of preys in the prey begin diminishing, the predators begin to decrease because of the starvation.
Thus, The right answer is the prey-predator relationship.
