Nostrana [21]3 years ago
3 0

Answer:

A tick sucking a deer's blood

Explanation:

All other examples show mutualistic relationships - both species benefit from the relationship.  With parasitism the one species benefits (the tick) while the other suffers (deer).

Which conditions are common to all three of the following: genetic drift, the founder principle, and the bottleneck effect? a. i
Tcecarenko [31]

Explanation:

Common to genetic drift, the founder principle, and the bottleneck effect:

b. in small populations and result in a decrease in genetic diversity and/or an increase in the occurrence of specific genetic traits

c. when a small group of organisms only reproduce with each other to create a larger population of organisms

d. when the majority of a population is killed off and there are only a few remaining organisms left to rebuild the population

Further Explanation:

During the process of cell division, spontaneous changes within the genome can arise, called mutations. These are errors occur when copies of the DNA within the cell are made; mutations may range from small changes called single nucleotide polymorphisms, to large scale deletions, and additions which span multiple genes.

These mutations form variants which become stable within a population, leading to the formation of separate, genetically distinct populations called species.

  • mutations accumulate in a population over time, altering the frequency of alleles or different forms of a gene- this is called genetic drift.
  • In the founder effect, the separation of a group from a larger group can decrease genetic diversity, this can create a genetically distinct population
  • In the bottleneck effect, a population die off or barrier to reproduction increases the genetic drift in the population

Which of the following are some examples of rapid environmental changes? A) Succession B) Fires C) Weather D) Landslide​
kenny6666 [7]

Weather is an example of rapid environmental changes.

Explanation:

Environment refers to our natural world surroundings. Rapid means fast or quick. Weather around us keeps changing as the earth rotates and revolves around the sun. It changes depending on the month of the year or may change from day to night. You can also note the room temperature at different times in a day, it keeps changing mostly minorly but it does change. There are sunny, foggy, rainy, cold etc days and hence we can say that weather is example of rapid environmental changes.

Studying the folding patterns of protein molecules can help microbiologists better understand cellular processes as well as some
xz_007 [3.2K]
The best answer in this case is C, "the researchers applied creativity to solve a problem in running an experiment".

Distributing the computing load across the global community by sharing processing power is a creative response to tackle the challenge in simulating protein folding for the experiment. This does not change or reduce the scientific merits of the experiment, so we can discount the first two answers (a & b). Answer d talks about well established scientific techniques, although the question wasn't really centered around the specific techniques, so it's not as relevant an answer as C.
