The specific properties of the most desired organic semiconductors for solar panel technology may evolve as advancements are made in the field.

In the context of solar panel technology, the most desired type of organic semiconductors would typically possess the following characteristics:

High Efficiency: The organic semiconductors should have a high power conversion efficiency, meaning they can efficiently convert sunlight into electricity. This is crucial for maximizing the electricity output of solar panels.

Tunable Bandgap: Organic semiconductors with a tunable bandgap would be advantageous. The bandgap determines the range of light wavelengths that can be absorbed by the material. A tunable bandgap allows for optimization to match the solar spectrum, enabling better absorption of sunlight and improved overall efficiency.

Long Operational Lifetime: The organic semiconductors should be stable and exhibit a long operational lifetime. Solar panels are expected to endure outdoor conditions for many years, so the materials used should be resistant to degradation, such as from exposure to UV radiation or moisture.

Scalability and Low Cost: Manufacturers aim to produce organic semiconductors on a large scale at a low cost. Therefore, desirable organic semiconductors should be readily synthesized using cost-effective methods and be compatible with high-volume manufacturing processes.

Environmental Friendliness: Organic semiconductors that are environmentally friendly and have low toxicity are desirable. This is aligned with the goal of sustainable and clean energy technologies.

It is important to note that the field of organic semiconductor research is still evolving, and scientists are continually working to improve the performance and characteristics of these materials.

The surface area-to-volume ratio of a cell diminishes with growth. If the cell were in the form of a cube, the same reasoning would hold true. The plasma membrane won't have enough surface area if the cell enlarges too much to accommodate the volumetric rise in diffusion rate.

In other terms, a cell gets less effective as it develops. One technique to increase efficiency is to divide, while another is to create organelles with specific functions. Smaller single-celled creatures have a high surface-to-volume ratio, which enables them to rely on material and oxygen diffusion into the cell (and waste diffusion out) to survive. This method can be more effective if the objects have a larger volume to surface area ratio. Larger animals need specialized organs (such as the lungs, kidneys, and intestines) that efficiently increase the surface area accessible for exchange activities, as well as a circulatory system to transport materials and heat energy between the organism's surface and core.

G typical Human cells=\(2.6772*10^{9}\) residues.

C typical Human cells=\(2.6772*10^{9}\) residues.

Explanation:

Given:

Number of human genome in pairs=2.91*10^9 base pair

Number of Human genome single bases=\(2*2.91*10^{9} =5.82*10^{9}\) bases

We know that human genome are diploid, Total Human genomes will bases will be \(2* 5.82*10^{9}=1.164*10^{10}\) bases

Since A is 27%:

A typical Human cells=\(0.27*1.164*10^{10}\)

A typical Human Cells=\(3.1428*10^9\) residues.

The Number of T and A residues are same in human genome. So,

T typical Human cells=\(3.1428*10^9\) residues.

Since A and T combined form 54% of human genome then G and C form 46% combined and 23% each.

G typical Human cells=\(0.23*1.164*10^{10}\)

G typical Human cells=\(2.6772*10^{9}\) residues.

The Number of G and C residues are same in human genome. So,

Explanation:

No, plants do not take in air with their roots. Roots are designed to absorb water and minerals from the soil. In order to get the air and carbon dioxide they need for photosynthesis, plants have specialized structures called stomata in their leaves and stems that allow air to enter and exit. These stomata regulate the movement of gases into and out of the plant, so the plant can take in the carbon dioxide it needs and release the oxygen it produces.
