B.
the drifting of the continents
C.
the changes in Earth's magnetic field
D.
a transfer of gases from the Sun

Answers

Answer:

The answer is A

Explanation:

The appearance of oxygen-producing organisms.

The appearance of free oxygen in Earth's atmosphere led to the Great Oxidation Event. This was triggered by cyanobacteria producing oxygen that was used by multicellular forms as early as 2.3 billion years ago.

What are cyanobacteria?Cyanobacteria are aquatic and photosynthetic, that is, they live in the water, and can manufacture their own food. Because they are bacteria, they are quite small and usually unicellular, though they often grow in colonies large enough to see.Cyanobacteria are responsible for the Earth's transition from a carbon dioxide-rich atmosphere to the present relatively oxygen rich atmosphere as a consequence of oxygenic photosynthesis.

Naomi runs a computer simulation for a population of mice in a meadow ecosystem. The simulation begins with 100 mice, divided equally among brown and white variants. The variants are similar apart from their body color. A mating of a white and brown mouse may produce a speckled mouse, which is mostly brown with some white markings. The table shows the numbers of each mouse variant over 7 reproduction cycles. Only adult mice are reported in the table.
Which of these events did the computer MOST LIKELY include in its simulation?
A. After cycle 2, a disease arrived that affected white mice only.
B. After cycle 2, a predator arrived that saw white mice more easily than brown mice.
C. After cycle 4, brown mice and white mice began living separately, and stopped interbreeding.
D. After cycle 4, a predator arrived that saw white mice more easily than brown mice.
E. After cycle 4, a disease arrived that affected brown mice only.

Answers

After cycle 4, a disease arrived that affected brown mice only was most likely included in its simulation.

During _____, the homologous chromosome pairs independently align themselves at the equator of the cell.

Answers

Answer:

Prophase I

Explanation:

During prophase I, homologous chromosomes pair up and exchange sections of DNA.

During prophase I, the homologous chromosome pairs independently align themselves at the equator of the cell.

What happens in prophase I?

DNA replication precedes the start of meiosis I. During prophase I, homologous chromosomes pair and form synapses, a step unique to meiosis. The paired chromosomes are called bivalents, and the formation of chiasmata caused by genetic recombination becomes apparent.

Moreover, during prophase I, the complex of DNA and protein known as chromatin condenses to form chromosomes. The pairs of replicated chromosomes are known as sister chromatids, and they remain joined at a central point called the centromere.

Therefore, during prophase, the chromosomes in a cell's nucleus condense to the point that they can be viewed using a light microscope. Prophase is the first phase of mitosis. During this phase, the chromosomes inside the cell's nucleus condense and form tight structures.

Based on the diagram, what would happen if Earth had no atmosphere?

Diagram of greenhouse effect showing the sun, atmosphere, and human activities that release greenhouse gases. The diagram shows that sunlight is reflected back to space by the atmosphere, absorbed at the surface, and reflected by the surface. Greenhouse gases trap heat from the sun. Examples of human activities include CFCs and haloalkane from refrigerators and aerosols, nitrous oxide from gasoline and agriculture, methane from cattle and fertilizer, and carbon dioxide from oil and coal.

Human activities would not release greenhouse gases.
Greenhouse gases would not trap heat from the sun.
Sunlight would not be absorbed at the surface.
Surface temperatures would be maintained.

Answers

Based on the diagram, we can confirm that if Earth had no atmosphere, Greenhouse gases would not trap heat from the sun.

Why would these gases not trap heat from the sun without the atmosphere?

Greenhouse gases are located in the atmosphere, therefore, without it, they would not be able to trap the heat from the sun. Although high concentrations of these gases are a modern problem in global warming, these gases are a natural part of the earth and are necessary to maintain livable temperatures at the surface of the earth.

Therefore, we can confirm that if Earth had no atmosphere, Greenhouse gases would not trap heat from the sun.

How does the mutation rate affect the speed at which a population adapts to its environment?

Answers

Answer:

Under these conditions an increase in the mutation rate evolves, which allows faster adaptation to the spatial variation in local temperature, causing a faster range expansion across the spatial gradient.

Answer:

The mutation rate is the speed (or mutations per unit time) at which a sequence of DNA changes, either through natural means or artificially induced means. Natural selection is the way that a population of organisms evolve over time to adapt to their environment.
