Two frog populations (same species) living in two neighboring lakes sing slightly different courtship songs. Increased irrigation makes the land between the two lakes wetter, allowing frogs to expand their ranges to the area between the lakes. Females in both populations prefer loud frogs to quieter frogs but do not distinguish between the two slightly different songs. Assuming that courtship song differences are due in part to genetic differences, predict what will likely happen to the songs of the two frog populations.

a. The gene flow between hatchery-reared and wild populations is leading to a decline in fitness of wild populations.
b. The gene flow between hatchery-reared and wild populations is neither helping nor hindering the fitness of the wild population.
c. This data does not help us understand effects of gene flow on fitness. The gene flow between hatchery-reared and wild populations is increasing the fitness of the wild populations.
d. You cannot predict a change in the courtship songs at the two lakes.

Answers

Answer 1

Answer:

I am pretty sure that the answer is B or D

Explanation:

a decline in fitness doesn't really make sense, because we are talking about courtship songs, not health. C.) doesn't make sense either, because at the end of the sentence it says that the fitness of the population is growing. again, we are talking about songs. Both b and d make sense.

Researchers are investigating the incidence of algal blooms in neighborhood ponds. In summer, they collect water samples from over 100 neighborhood ponds in Dallas, Texas and surrounding cities. They also surveyed residents in each neighborhood to collect data such as average lot size, average home value, average resident income, and lawn care methods. The researchers found that neighborhoods with large lots, high home values, and high income levels were likely to use automatic sprinklers and synthetic fertilizers on their lawns. These same neighborhoods were very likely to have abundant algae in their ponds. Based on this research, which conclusion below provides the best explanation for why algae proliferate in neighborhood ponds?

a. Automatic sprinklers may house algae and may spray into neighborhood ponds.
b. High income neighborhoods are less likely to treat their ponds with chemicals that prevent algae growth.
c. Lawn fertilizer that washes into neighborhood ponds likely causes algae to become more abundant.
d. Neighborhoods with expensive homes typically have larger, deeper ponds that are more likely to support algae proliferation.
e. Large lot sizes likely provide algae with extra room to grow, and the algae then washes into the pond.

Answers

Answer: c. Lawn fertilizer that washes into neighborhood ponds likely causes algae to become more abundant.

Explanation:

Eutrophication is a natural phenomena in which the algal growth occurs in the water body due to increase in concentration of the fertilizers and manures being drained from the agricultural land into water. This causes decrease in oxygen level in water, and the aquatic animals in water will not survive due to scarcity of water.

According to the given situation, the growth of algae in the neighboring ponds is due to the drainage of lawn fertilizers into the neighboring ponds being washed from the lawns. This causes algae to grow abundantly in ponds.

A student studying aquaculture is interested in how diet and water temperature affect the growth rates of fish. She hypothesizes that fish receiving a high protein diets and in warmer temperatures will have enhanced growth rates. She has four treatment groups:______

a. Fish tanks in a laboratory at 22 degrees C and high protein diet.
b. Fish tanks in a laboratory at 22 degrees C and low protein diet.
c. Fish tanks outside with a temperature of 26 degrees C and high protein diet.
d. Fish tanks outside with a temperature of 26 degrees C and low protein diet.

Answers

Answer:

Explanation:

This question is not complete below is the remaining part of the question. Is her hypothesis a true hypothesis or merely a prediction? (Has she provided rationale for her hypothesis?)

Do you think this is a good experimental design? Do you have suggestions for how she could improve her experimental design?

Answers:

The result of the experiment will determine if the hypothesis will be accepted or rejected and further explanation will be given to the effect.

Increase in dietry protein will subsequently increase the body weight as such the result show should tend towards a positive response to an increase in protein level.

The experiment design is completely randomized design(CRD) and it is good for the experiment to have the temperature all monitored and a close watch on the fishes.

Summarize what reasherchers did to improve the quality of post mining sites soil in

Answers

Answer:

The researcher centred on the potential uses of biochar, charcoal primarily used for agricultural and to improve the quality of post mining sites.

A method called mountaintop removal was used by mining firms. This means that they remove rock and mineral deposits off the top of the mountain to gain access to within the coal seams. The resulting soil is infertile and strongly acidic. The compacted soil after mine proves harder to  bring seed into the soil.

The researchers  try to use biochar to help reforest the soil at the post-mining site. Before it was reseeded and replanted, they got permission to add a layer of biochar to a post-mining site. the team created “planting cells” of biochar‐enhanced soil on the post‐mining site and that showed improvment in the sapling growth.

The photograph shows rockweed. Which feature allows rockweed to
withstand the constant wave action of its environment?
A. The ability to carry out chemosynthesis
B. The ability to firmly attach to rocks
C. The ability to produce its own light
D. The ability to carry out photosynthesis

Answers

Answer:

B

Explanation:

This is the answer because if the rockweed is able to firmly attach its self to the rocks it would be able to withstand the constant wave action

The tendency to firmly attach to rocks allows rockweed to withstand the constant wave action of its environment.

Rockweed

It is a brown alga and grows in the rich intertidal zone.

The holdfast of a rockweed permits it to withstand the constant wave action of its surroundings.

Holdfast is a tiny stem-like composition which allows the weed to anchor firmly to the rocks.

The rockweeds possess some of the advantages over the normal weeds that permits them to sustain in water like the intense developed root systems.

Thus, the correct answer is option B, that is, the ability to firmly attach to rocks.
