GREYUIT [131]3 years ago

Answer: In the lab activity, I used a virtual watershed to demonstrate how pollutants enter and flow through the watershed. I constructed food chains to show how biotic factors are related. I also predicted and modeled how human activity affected the biotic factors in an ecosystem. Based on my observations, I can conclude that biotic and abiotic factors are closely linked and that human activity that changes the environment, like pollution, can affect all the other parts of an ecosystem in a negative way.

What happened to the California Condors?
expeople1 [14]

Answer:

B

Explanation:

California Condors have been in decline about as long as European Settlements began to spread across North America. These birds have been on the U.S endangered species list since 1967 and were near extinction when their captive-breeding program began. California Condors also mature and reproduce slowly.

Which Mechanism of microevolution caused the the beak of the medium gound finch population on dafne major to increase in size in
expeople1 [14]

Answer:

Natural selection

Explanation:

Microevolution refers to changes produced at a lower level than species. In genetics, microevolution is the change in the allelic frequency perceptible in a few generations. Most of these naturally produced changes by mutation, natural selection, genetic flux, genetic drift.

After the drought on Daphne Major, many of the plants producing small-sized seeds decreased their reproductive rate drastically. Consequently, there were almost no seeds available for the medium ground finch to feed. The population of this species also decreased to only a hundred birds over two years. Weather conditions and food availability influenced the survival of the animals.

With time, the finched population increased again, but now, the average size of the beaks was larger. The trait modification was related to the availability of only larger seeds with thick husks.

Eating large seeds with medium or small-sized beaks was impossible, so Finches needed to adapt, developing larger beaks to crack open the husks and eat the contents of the seeds.

<u>Natural selection was responsible for the rapid change in the finches´ population beaks size after the drought. </u>The evolutive force modifies the allelic frequencies, increasing the frequency of genetic variants that expressed the larger beak size and declining the frequency of the alleles that expressed smaller beak size.

Where does dna replication occur
prohojiy [21]

Answer:DNA replication occurs in the cytoplasm of prokaryotes and in the nucleus of eukaryotes.

Explanation: Regardless of where DNA replication occurs, the basic process is the same. The structure of DNA lends itself easily to DNA replication. Each side of the double helix runs in opposite (anti-parallel) directions.
