When humans dig-up fossil fuels and burn them to power the modern world, carbon flows between which two reservoirs of the carbon cycle? * A. Hydrosphere and biosphere B. Geosphere/lithosphere and atmosphere C. Atmosphere and biosphere D. Hydrosphere and geosphere/lithosphere

Answers

Answer:

B

Explanation:

When humans dig-up fossil fuels and burn them to power the modern world, carbon flows between the Geosphere/lithosphere and the atmosphere.

Both the geosphere and the atmosphere represent important reservoirs of carbon. The digging-up of fossil fuels, otherwise known as exploration, is carried out in the geosphere or the lithosphere part of the earth. For example, crude oil is obtained deep from the ground. When the fuels are burned, they release carbon in the form of carbon dioxide into the atmosphere.

Hence, it can be concluded that carbon flows from the geosphere/lithosphere part of the earth to the atmospheric portion of the earth when fossil fuels are burned.

The correct option is B.

Important vocabulary continued: label and illustrate an autotroph and a heterotroph organism. Underline the one that produces its own food. If you can answer 3 also that would be nice

Answers

2. autotrophs make their own food/nutritional organic substances, an example would be plants because they undergo photosynthesis! heterotrophs have to seek out their food, they can’t produce it themselves. so this would be a lion, a human, a dog, etc.

Belinda asked her teacher, "What could make turtles go faster?"
Her teacher replied, "I don't know. See if you could find out."
So Belinda did a lot of research in the library and come upon the idea that
eating carrots will make turtles go faster. She decided to test her ten turtles.
She fed five turtles their normal turtle food. She fed the other five carrots. All
the turtles got their normal sleep and water requirements. Then, after a week
she had a turtle race. She kept a record of the times and realized that she was
wrong. In fact, all the carrot-eating turtles finished last.

How was the dependent variable measured?

The amount of sleep the turtles received

How fast the turtles ate

The turtle's speed in the race

Which evolutionary mechanism increases inheritable variations

Recombination of genes
Bottleneck ig of genes
Gene flow
Genetic drift

Answers

Answer:

Recombination Of Genes

Explanation:

Recombination of the gene's evolutionary mechanism increases inheritable variations, hence option A is correct.

What are genetic variations in a population?

Gene flow, recombination, and mutation are mechanisms that enhance genetic variety. There are more mechanisms that work to promote genetic diversity, but fewer that work to reduce genetic diversity.

Demographic bottlenecks tend to decrease genetic diversity by intensifying genetic drift, but because genetic drift is random and has local impacts owing to recombination, mutation, and selection, the overall impact may vary along the genome.

Because it introduces new variety into the population, the mutation is the only mechanism of evolution mentioned that increases the amount of genetic variation. Genetic drift is the haphazard loss of genetic variation over time.

Therefore, option A is correct.
