Answer:
The correct answer would be - Hydrangea plants depend on the concentration of some element which is affected by the acidic or basic nature of the soil.
Explanation:
Hydrangeas plants produce two different type of flowers blue and pink. The color of the plant depends on the pH of the soil or the acidic or basic nature of the soil. If the pH of the soil is acidic which means 5.5 or less the color of the flower would be blue and if it is near or above the 6.5 flowers would be pink.
So, it is clear that the concentration of any element that affected by the pH of the soil is responsible for the color of the flowers, in this case, it is found that the concentration of aluminum ions (Al+++) in the soil. When the soil is alkaline less concentration aluminum available for the plant and more available to the plant when the soil is acidic.
The color of hydrangea flowers is influenced by soil pH, with acidic soil producing blue flowers, and neutral to basic soil producing pink ones.
The information given about hydrangea plants and the color of their flowers is an example of how environmental factors can affect biological characteristics. Their flower color is determined by the soil pH. Acidic soil with a pH of 5.5 or less triggers the hydrangea plants to produce blue flowers, while soil with a neutral to basic pH of 6.5 and up causes the flowers to be pink.

The correct answer is scanning electron microscope and scanning tunneling microscope.
The SEM refers to a kind of electron microscope, which generates three-dimensional images of a specimen by scanning the surface with a focused beam of electrons. The electrons associated with the atoms in the specimen, generating different signals, which comprise data regarding the composition of the specimen and the surface topography.
An STM refers to an apparatus for imaging three-dimensional image surfaces at the atomic level. In this, good resolution is regarded to be 0.01 nm depth resolution and 0.1 nm lateral resolution.
The STM can be utilized not only in a high-ultra vacuum but also in water, air, and numerous other gas or liquid ambient, and the temperatures spanning from 1000 degree Celsius to zero Kelvin.
Endocytosis is a process that moves materials into a cell via vesicles. The cell's membrane folds inward to form a vesicle which then moves into the cell with the material. It is a way for cells to engulf materials in their environment.
Endocytosis is a process that moves materials into a cell via vesicles.
Specifically, during endocytosis, the cell's membrane folds inward to form a vesicle that contains the material to be brought inside the cell. This vesicle then separates from the cell membrane and moves into the cell, carrying its contents with it.
This is a way for cells to engulf and 'eat' materials in their environment, which can include things like nutrients or other smaller cells.
