This image was taken with a microscope that clearly shows the mitochondrion of a cell. Which of the following describes the types of microscope that was used.

Answers

Answer:

Explanation:

To determine the type of microscope used to capture the image of a cell's mitochondrion, you would typically need additional information, such as the features of the microscope and the microscopy technique employed. Microscopes commonly used to visualize cell structures include optical microscopes, electron microscopes, and fluorescence microscopes, each with its own capabilities and applications. If you have more details about the image or the microscope used, I'd be happy to provide further assistance.

Before 1800, most peppered moths in England were light-colored. During the Industrial Revolution, soot and industrial wastes darkened tree trunks. Gradually, the light-colored moths became rare, and the dark-colored ones became abundant. What role did natural selection play? A. Natural selection created the variation in the population, and then acted accordingly.
B. Natural selection acted on the variation that was present in the population.
C. Natural selection acted indiscriminately on both color variations.

Answers

The correct answer of this question is option B. Natural selection acted on the variation that was present in the population. This adaptation was a result from the Industrial Revolution. The dark-colored moths have camouflaged more effectively than the light-colored ones.

Answer:

B. Natural selection acted on the variation that was present in the population

Why is deforestation in tropical rainforests more devastating to the global environment than deforestation in temperate forests? (Points : 4) most temperate forests are not experiencing deforestation tropical rainforests provide less useable lumber temperate forests do not contribute to the reduction of carbon dioxide tropical rainforests are inhabited by indigenous tribes who are losing their way of life tropical rainforests have much higher biodiversity than temperate forests

Answers

I believe the answer is tropical rain forests have much higher biodiversity than temperate forests. Tropical rain forests usually have a lot of exotic animals and plants life. Temperate forests don't really have a lot of biodiversity compared to the tropical rain forests.

Answer:

tropical rain forests have much higher biodiversity than temperate forests.
