Most biology textbooks prior to 1990 listed the major function of ribonucleic acid (RNA) as transferring information from DNA to make proteins. In late 1989, Thomas Cech proposed that RNA had a second major function: as a catalyst for chemical reactions that occur inside the cell. His discovery surprised most scientists and caused the rewriting of many chapters in biology textbooks. What aspect of the scientific process does this best illustrate?

Answers

Answer 1

Answer:

The correct answer would be - overgeneralization of a hypothesis.

Explanation:

In this case, the scientist uses to think and listed the transferring information from DNA to make proteins as the main and major function of the RNA until Thomas Cech proposed that it is the second most important catalyst that takes place in the cell and catalyzes cell's chemical reactions.

This illustrates major aspects of the scientific process: overgeneralization of a hypothesis as RNA is not just a molecule that assists and transfers the information but new evidence found it has catalytic activity also.

Describe how climate would be influenced if:
Earth’s distance from the sun was to change.

Earth’s tilt changed.

Describe how climate would be influenced if:

An asteroid or comet would impact earth.

Solar activity decreased and increased.

Answers

The rate of energy coming from the Sun changes slightly day to day. .It has been suggested that changes in solar output might affect our climate—both directly, by changing the rate of solar heating of the Earth and atmosphere, and indirectly, by changing cloud forming processes.The axial tilt angle affects climate largely by determining which parts of the earth get more sunlight during different stages of the year Likewise, during winter for the northern hemisphere, there would be fewer hours of daylight because the northern hemisphere would essentially be pointed away from the sun.If an asteroid were to strike land or a shallow body of water, it would eject an enormous amount of dust, ash, and other material into the atmosphere, blocking the radiation from the Sun. This would cause the global temperature to decrease drastically.The Sun's irradiance has its greatest effect on Earth's upper atmosphere, while the lower atmosphere insulates Earth from the increased heat. If the Sun were driving Earth's warming, one would expect to see that upper atmosphere getting increasingly hot.\have a nice day sorry if wrong T_T

Answer:

A gene is a section of a double-stranded molecule known as DNA. This molecule is found within the nucleus of the cell, contained in threadlike structures called chromatin. The two strands form a double helix linked by a series of paired bases. The base adenine is always linked to thymine and the base cytosine is always linked to guanine.

does photosynthesis remove take or use co2 from atmosphere?

Answers

Answer:

Take in

Explanation:

During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. This transforms the water into oxygen and the carbon dioxide into glucose. The plant then releases the oxygen back into the air, and stores energy within the glucose molecules.

Simple migration or movement of animals is important for increasing the gene pool and is an example of ____

Answers

Answer:

Gene flow

Explanation:

The gene flow refers to the migration, movement and transfer of genetic material between groups of different regions. In other words, this flow can happen with the migration of animals and with the transport of the pollen of the plants, which allows the DNA of an organism in one region, be transported to another and produce offspring there with the same genetic material.

In summary, we can say that the simple migration or movement of animals is important to increase the gene pool and is an example of gene flow.

The data showed that recently the alligator population has decreased. How could the decrease in the alligator population affect the other populations? Be sure to explain whether the gar population, the diving duck population, and the crab population will change, and why.

Answers

Answer:

The correct answer is -

Gar population: increase

crabs: decrease

diving duck: decrease.

Explanation:

As it is known that alligators eat gar in any aquatic ecosystem and gar depends on the crabs for their food and nutrition and share the crab population as food with diving ducks in a particular ecosystem. So if the alligator population decrease in the ecosystem then The gar population will increase as there are fewer or no alligators eating them.

And as the population of gar will increase then there would be a decrease in the population in crab population as there will be more gars to eat them and the population of diving duck will reduce due to the increase in the gar population which results in competition for the crabs as food.
