Between 1993 and 2003, there was a significant shift in the population dynamics of elk and wolves in Yellowstone National Park. Prior to the reintroduction of wolves in 1995, elk populations were at an all-time high, with estimates of over 19,000 individuals in the park.
However, with the reintroduction of wolves, elk populations began to decline, as wolves predated on elk and limited their ability to thrive. By 2003, the elk population had dropped to around 8,000 individuals. In contrast, the wolf population increased from 31 individuals in 1995 to 118 individuals in 2003. This was largely due to the success of the wolf reintroduction program, which allowed wolves to reestablish themselves as top predators in the ecosystem. The population dynamics of elk and wolves in Yellowstone National Park during this period illustrate the importance of predators in maintaining the balance of ecosystems, and the potential for reintroduction programs to restore lost ecological relationships.
In summary, the trend between 1993 and 2003 shows an increase in the wolf population due to the reintroduction efforts and a subsequent decline in the elk population as a result of increased predation.

In a population that meets the Hardy-Weinberg assumptions (i.e. is in equilibrium), 81% of the individuals are homozygous for a recessive mutation. Assuming there are two alleles for the affected gene, what percentage of the individuals in this population would be expected to be heterozygous?
A. 18
B. 81
C. 9
D, 1
A. 18In a population that meets the Hardy-Weinberg assumptions, allele and genotype frequencies remain constant over time. This means that the frequencies of dominant and recessive alleles in the population remain the same.
Given that 81% of individuals are homozygous recessive, we can use this information to calculate the frequency of the recessive allele using the following equation:
p^2 + 2pq + q^2 = 1
where p^2 represents the frequency of homozygous dominant individuals, 2pq represents the frequency of heterozygous individuals, and q^2 represents the frequency of homozygous recessive individuals.
If 81% of the population is homozygous recessive, then q^2 = 0.81, and therefore q = sqrt(0.81) = 0.9.
Since there are only two alleles in the population, the frequency of the dominant allele (p) can be calculated as 1 - q = 0.1.
Using the equation above, we can now calculate the frequency of heterozygous individuals as:
2pq = 2(0.1)(0.9) = 0.18 or 18%.

both a. niger and b. subtilis cultures used in this experiment contained spores. why is b subtilis more heat resistant
Bacillus subtilis is generally more heat resistant than Aspergillus niger because of its ability to form endospores, which are highly resistant to heat and other environmental stressors.
Endospores are a dormant and highly resistant form of bacteria that can survive in adverse conditions such as heat, drought, and exposure to chemicals. Bacillus subtilis is known for its ability to form endospores, while Aspergillus niger does not have this capability.During heat treatment, endospores are able to withstand high temperatures due to their tough outer layer, which contains various protective proteins, small acid-soluble proteins, and dipicolinic acid. These compounds make the endospore resistant to heat, radiation, and other harsh environmental conditions.In contrast, the heat resistance of Aspergillus niger is likely due to other factors, such as the production of heat-shock proteins, which can protect the organism from heat-induced damage.
