A biologist studies a population of anteaters living in a large nature reserve. The reserve is surrounded by farms where anteaters are not safe, but the reserve is a perfect place for anteaters: there are few predators and lots of ants. The biologist counts the number of anteaters in the reserve every year for twenty years and finds the size of the population does not change much. Which of the following is the best description of what life in this reserve is probably like for these anteaters?a. The anteaters have little or no difficulties obtaining food and raising offspring. ants. Their tongues are 24 inches long and covered with sticky saliva. Anteaters cannot open b. Adult anteaters compete for food and many young anteaters die. theirmouth, and do not have teeth. Even the stomachs of anteaters are unique: unlike most mammals,c. It is impossible to know without actually observing anteaters in the reserve.

increasing intracellular cAMP leads to smooth muscle relaxation by: Group of answer choices inhibiting IP3 channels, leading to decreased Ca2 in the sarcoplasm and reduced contraction. Increasing the relative activity of MLCP, leading to a decrease in tension. Activating K channels, increasing K leaking out of the cell which hyperpolarizes it and decreases the likelihood of Ca2 entry. Lower levels of MLCK activity, leading to decreased contraction.

During hydrolysis, what molecule is used to split a large compound?

Dr. Nachman and his colleagues collected rock pocket mice across 35 kilometers of the Arizona Sonoran Desert, which included both dark, rocky lava outcrops and light, rocky, granite areas. They recorded substrate color, and coat-color frequencies for each location. Each site was separated from any of the others by at least eight kilometers. The researchers trapped a total of 275 mice. Their data are summarized below (numbers have been slightly modified for the purposes of this worksheet).

5. Which fur color seems to have the greatest overall selective advantage?
6.What environmental change gave a selective advantage for one coat color over another?
7. In a separate study, 76 rock pocket mice were collected from four different, widely separated areas of dark lava rock. One collecting site was in Arizona. The other three were in New Mexico. Dr. Nachman and colleagues observed no significant differences in the color of the rocks in the four locations sampled. However, the dark-colored mice from the three New Mexico locations were slightly darker than the dark-colored mice from the Arizona population. The entire Mc1r gene was sequenced in all 76 of the mice collected. The mutations responsible for the dark fur color in the Arizona mice were absent from the three different populations of New Mexico mice. No Mc1r mutations were associated with dark fur color in the New Mexico populations. These findings suggest that adaptive dark coloration has occurred at least twice in the rock pocket mouse and that these similar phenotypic changes have different genetic bases. How does this study support the concept that natural selection is not random?
8. To determine if the rock pocket mouse population is evolving, explain why it is necessary to collect fur color frequency data over a period of many years.

A deleterious recessive allele is one that can be harmful when it is found in its homgous condition, resulting in a poorly fit phenotype. An example of this is the allelefor sickle cell, which results in the condition known as sickle cell anemia when both recessive alleles are inherited. owever, in regions of Afriche proportion of the sickle cell allele is igher than expected, with as much as 15% of the alleles in the population being the recessive, deleteriou rsion. In the African population, there is also a high prevalence of malaria, a disease caused by the parasitic infestation of a plasmodium protozoan in the blood of humans. The recessive allele for sickle cell has been maintained over many generations. Evaluate the graph above and select the claim that supports the high frequency of the recessive allele in these African populations.
A)There is a selective advantage to the aa genotype, as the presence of sickle cell provides a greater fitness in an environment where malaria is common.
B)There is a selective pressure against the aa genotype, but the presence of malaria induces new mutations which generates more alleles within the population.
C)There is directional selection towards the Aa genotype, since aa is often a lethal condition. Non-random mating tends to maintain the recessive allele in the population.
D)There is a selective advantage to the heterozygous (Aa) condition as there is selective pressure against both the AA and aa genotypes. This maintains the recessive allele in the population.
