Over time, a tadpole changes into a frog. Has it evolved?

Biology

viva [34]3 years ago

Answer:

The correct answer would be "No because its genes are still the same".  

The process by which a tadpole changes into a frog is termed as metamorphosis, not evolution.

During this process, the physical transformation of an organism takes place through cell growth as well as cell differentiation.

No genetic transformation takes place and thus, no evolution takes place during this transformation.

No, because its genes are still the same. To evolvewould mean that the frog had one set of genes as a tadpole, then a different set as an adult. It just doesn't work that way. The genes are the same.

mr Goodwill [35]

Answer:

Green plants have the ability to make their own food. They do this through a process called photosynthesis, which uses a green pigment called chlorophyll. Chlorophyll is located in a plant's chloroplasts, which are tiny structures in a plant's cells. This is where photosynthesis takes place.

1. The burning of fossil fuels contributes to all of the following ecological problems except for:
kirill115 [55]

The burning of fossil fuels does not contribute to ozone layer depletion.

The burning of fossil fuels leads to the release of gases such as oxides of nitrogen, sulfur, and carbon as well as particulate matter such as smoke, ashes, etc.

The oxides released from fossil fuel burning can cause global warming (carbon dioxide), acid rain (SO2), and air pollution (particulate matter).

Ozone layer depletion is caused by pollutants such as halocarbons, solvents, etc.

Which of the following functions does the myelin sheath perform for a nerve cell?
Ira Lisetskai [31]

Answer:

a. insulation  

Explanation:

The myelin sheath provides increased cell isolation (increased membrane resistance) because there are no membrane leakage channels in which there is myelin.

In addition to no membrane leakage channels, there is also virtually no type of membrane channel when there is myelin sheath (eg sodium and potassium pumps), which causes the cell a lower need for protein synthesis, or that is, less energy expenditure.

Which action would most likely increase the rate of an enzyme-controlled reaction during an experiment on human enzymes? 1 point
Mekhanik [1.2K]

Answer:

Raising the temperature from 20c to body temperature

Explanation:

The increase in temperature will give the particles more thermo energy therefore it will increase the rate of an enzyme-controlled reaction

Which of the following are NOT correct based on Darwin's theory of evolution?
Black_prince [1.1K]

Answer:

D variations in individuals are not heritable

Explanation:

Genetic variation in individuals is what drives evolution. In a population of individuals in an environment, with the adequate resources, overpopulation can occur. However, resources are usually a limiting factor for population growth: there is not sufficient food/shelter etc. for everyone to survive.

Some individuals are better suited to success in the environment. This is because of random variation in their DNA that has arisen that give them a selective advantage. This allows them to thrive, take advantage of the limited resources over other members of the population, and be more likely to survive to reproductive age. This is natural selection.

Because this variation is genetic (in the DNA), they can then pass it on to their offspring. Over time, this leads to evolution over time.
