The Miller-Urey experiment simulated compounds present in the atmosphere of early Earth, lightning, and the evaporation and cond

ensation of atmospheric water. What other information about the conditions on Earth during this time period would you want to know to improve the experiment?

Answer:

The Miller-Urey experiment was conducted to simulate the conditions on Earth when life arose, and see if a chemical evolution could occur. This experiment was performed without oxygen, because they knew that if oxygen was added, the amino acids would oxidize. In particular, the experiment intended to simulate a volcanic eruption was analyzed.

Thus, particles of water, methane, ammonia and hydrogen were exposed to high temperatures and electric discharges that simulated these eruptions, during a determined period. Later, it was observed that organic compounds had emerged from this exposure, which allowed us to infer one of the hypotheses regarding the origin of life on Earth.

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

In pan mixia, in the absence of migration, mutation, and selection the frequencies are A) Constant in genotype and phenotype B)
muminat

Answer: option A - Constant in genotype and phenotype

Explanation:

Pan mixia is a situation in which an individual is just as likely to mate with another randomly chosen individual as any other in the population

In a situation as described in the question, sexual reproduction is limited to organisms of the same habitat, thus the genetic variation is reduced to the BAREST MINIMUM.

This results in Constancy in genotype and phenotype

Which food item contains a lot of processed simple sugars?
Molodets [167]

The right answer is B. cookie.

Sucrose, or sucrose, is a sugar derived from sugar beet or sugar cane. It is also known as table sugar (used in cooking and baking). Comprised of fructose and glucose, sucrose is known for its sweet and sweet taste particularly appreciated. However, and despite the pleasure it provokes, sucrose consumed in excess would represent a major danger to health.
