Gallardo and Araneda (1994) studied populations of the rodent, Ctenomys maulinus, before and after an eruption of a volcano in t

he Andes. Survival was random, and the rodent populations after the eruption were only a small fraction of the size of populations before the eruption. Which of the following is likely to be TRUE of the surviving populations relative to the populations before the eruption?
a) Remaining populations will have reduced genetic diversity
b) Adaptive alleles have decreased in frequency
c) All of the answer choices are possible outcomes in this scenario.
d) Maladaptive alleles have increased in frequency

Answer:

A) Remaining populations will have reduced genetic diversity

Explanation:

A random mating population allows for genetic diversity as each individual have equal chance of been mated to and it allows for perpetuation of frequently occurring genes.

For a small population the frequency of allele is mostly fix with virtually all loci having the same genotype because mating is within small individual and genes whose frequency is few will be drifted out of the population.

Hence, after the eruption due to a small random population diversity will be reduced as diversity occur more in a large random mating population.

“20.2 Graphical representation of vectors (ESAGK)
Vectors are drawn as arrows. An arrow has both a magnitude (how long it is) and a direction (the direction in which it points). The starting point of a vector is known as the tail and the end point is known as the head.”

Can you use mass alone to predict whether an object will sink or float? Explain.
natima [27]

Answer:

No, you need both mass and volume to determine its desity to see if it can float.

Explanation:

Density is the only thing affecting whether something floats or sinks. If an object has a higher density than the fluid it is in (fluid can mean liquid or gas), it will sink. If it has a lower density, it will float. Density is determined by an object's mass and volume.
